Have you had a look at it yet?  Best to unbolt the converter bolts and loosen the gearbox bolts and see if you can push the converter all the way into the gearbox. Do it while rotating the converter it should noticeably click or clunk into place. Then bolt the gearbox to the engine correctly so there is no gap. And then bolt the converter to the flexplate.

Yeah I took a three day holiday, and worked on car on hoist. Working over the weekend on it as well.

I took the auto box out. Tailshaft off, Pipe at the back off, Gear selector out of the way, Exhaust off (not sure if required). Had a transmission jack so made it pretty nice (Pro tip someone said its good to strap the gearbox to the jack).

I found that the one piece sandwich plate was the correct one. RWD auto sandwich plates don't have cut outs for AWD sump etc. Unfortunately I put the top of two piece sandwich plate on it before I compared or thought about it. So I cut the bottom off my original one and used that.

I learnt the hard way a couple times not to bolt the torque converter until the gearbox is bolted to engine properly.

While exhaust was off, I dropped the fuel tank, replaced 25YO fuel lines. Drained the tank had like 20L, thought I pumped it out previously. Treated rust above tank and exhaust. Sprayed black stone guard. Tow hook, rear exhaust hanger and rear heat shield are being powder coated black.

Remaining jobs:

-Fit A/C, Power steering  pump, connect starter motor, Drain some oil (put too much in), 

-Hook up heater hose. It has a oil head drain so I can't use factory hard pipes. Going to try silicon hoses from kit I got. with alloy joiners, clamps and silicon hose to link them. Putting some heat shielding wrap on as well.

-Replace fuel filter and front fuel hoses. Going to use a cheap filter run it for a bit then replace with a Nissan one. When I was draining fuel tank I used a paint filter and caught a lot of what looked like tobacco.

-Fit new belts.

-Fit radiator and pipes, fan and coolant. Check for leaks.

-Got to workout how to plumb transmission cooler and radiator to gearbox and do that.

-Find airbox and AFM and a bunch of clamps. and fit them. Add pipe from intercooler and turbo to airbox etc.

-Fix exhaust. Down the track I will replace it with a Jap one, once mrs ok with that.

-Fix some wiring VVT plug is broken so I don't know which pin goes where. Might have to drive up (three hour round trip) and see my R34 RB25DE NEO for pin colours. I probably have more parts I need anyway. 

-Grey six pin plug hanging off intake. Had three broken wires. Someone replaced them with bullet connectors. I don't know what connects to what. I assume that plug is something for auto box. It seems to have two black wires, two red wires and two white wires. Closer examination required. Other connector has different colours.

-Fit front CVs. Find CV joint Nuts and split pins and washers etc. No idea why I separated them from CVs. A boot needs replacing also.

-Turn engine over with no fuel. Check for bad noises.

-Going to run engine with portable fuel system to check before running from fuel system.

Got most of it together now.

I tried to fill the coolant, but leaked out the back of the engine. I removed the heater hoses, for now and bypassed the heater core. Found the small elbow behind the engine had loose clamps. Hopefully that will be the leak fixed. I find out today.

I had a crack at turning it over yesterday with my portable fuel system.

Battery was dead, but used jump starter.

Seemed to turn over ok, but seemed like no spark or fuel?

AFM plug doesn't click or fasten itself. But seems to be on ok.

Not sure if alternator belt too tight.

Ways to check oil pressure?

Any tips?

well, re oil pressure, you can either rely on the dash light going out, or while you are gabbing that battery grab a handheld oil pressure gauge at the same time and screw it into the oil pressure light sender port.

The battery is always a killer when trying to start a car after a while....its the last thing you think to prepare but really critical.....just need to go back in time 3 days and put it on a charger :rofl: 

If you are worried the alternator belt is too tight, back it off....the screaming when running will tell you...better than damaging the water pump or alternator bearings. Because the belt is so short you should be able to get about a half twist out of it when it is adjusted properly

Ha, had to go back to the start to check....4 pages and 3 years, sounds about right for a quick RB rebuild :)

Re no spark or fuel.....can you confirm this is a rebuilt engine being put back in the same car, and that it was running fine when removed? Lots of potential reasons for it not to be triggering properly....

Yeah same engine going back in.

The engine was previously over heating, pitted block.

But been off the road about five years now.

Fuel ins and outs were swapped, so swapped them back.

Topped up coolant. No more leaks from coolant today. I will bleed it once the engine gets running.

Battery was replaced. This new battery leaked acid so got another replacement today.

After work with a bunch of guys from work observing we manged to get the engine running. I think it seemed to run pretty well maybe not all cylinders. A little smoke started to come off the exhaust manifold. The we shut it down.

Unfortunately we couldn't get the engine to run again.

I had a hole in transmission hoses, this has been fixed.

Alternator belt was loose today. Had the wrong belt on alternator etc, put the middle sized belt on.

Going to fix some dodgie wiring, tomorrow (The grey 6 pin plug, think its for auto transmission).

The plug from the AFM doesn't catch. I might try another AFM, see if its the plug or the AFM. The plug looks OK.

Someone told me to remove the CAS and spin it by hand, with ignition on and see if injectors pulse. I assume the CAS normally spins anti-clockwise.

I'm going to bring a stethoscope and listen to each injector. Might also try tapping some fuel injectors to free up blocked ones.

Whats the best way to run an engine in? Someone said idle it for 24hrs. I am not sure about that.

Hopefully success will come for a change.

Definitely do not let it idle for 24 hours. I can’t remember exactly what you did to the engine but a few heat cycles without driving then a few light load drives making sure it gets up to temperature properly 15-20 minutes. Then drain and refil the oil and change the filter, checking for contaminants like bearings. then send it

So many questions in one post :rofl:

You can tell if the fuel lines are the right way around because it will only run the right way. Also the feed should be very firm for about 5 sec when you turn the key on or are cranking and the return will be squishier. Also the feed has the fuel filter in it. Having said all those things, it is soooooooooo common to put them on wrong way around.

I had a problem on a recent rebuild where the injectors had gummed up sitting around....might be worth getting them run through an injector cleaner.

A rebuilt engine will almost always smoke enough to think you have set it on fire, from oily/greasy finger marks on the manifold....only stop if you see flame not smoke  :)

finally.....never let an engine idle when running it in, other than to get it up to temp and do some basic leak checks. Once it is running you need to get out and drive it at different rpm levels (say 500rpm apart up to about 5000) and with at least some load. A good dyno operator can do that in about 30 min but generally due to different conditions on a road you might need 100klm. Don't just drive on a freeway either, find some hills or something for load

please don't do this, worse advice!

Just go for a normal drive, then eventually start to introduce load - don't be shy.

Fuel Feed -> Fuel Filter -> Rail -> FPR -> (I think your car has an OEM dampener) -> Return to tank

I got it running during the week.

Was the fuel ins and outs swapped again. They got swapped about four times on the build. Setup as per R34 photo above.

Seems very quiet the fuel pump is louder. Boys at work thought the exhaust output looked good.

Think its running on about five cylinders. So going to unplug injectors and see which cylinder is bad. Then workout if its gummed up injector or coil/spark plug etc. I'm expecting gummed up injector. Haven't done timing or anything.

Haven't bleed coolant yet as well.

I'm a bit worried i'm going to take a month or so to get it back on the road. So makes it hard to run it in. So far I haven't revved it over 1500rpm. Idles around 1000.

Lost my front shaft to hub fasteners. The nut, washer and split pin etc. I should of left them on the shafts.  Anyone got any spares?

  • 2 months later...

Update:

Done:

-Running on 6 cylinders, one injector was gummed up. I made an injector tapper, bit of Teflon on the end of a metal rod.  That fixed the injector. Need to replace one injector plug, the fastener is broken.

-Coolant bleed

-Fixed 4WD warning light, bleed 4wd system

-Fixed electrical problems: alarm, brake lights, various broken plugs 

-Got all the parts ready to connect head drain. Head drain is fitted with a blocker atm

Todo:

-Fuel pump dead, Been cleaning out the tank, had a lot of tobacco looking stuff, think its OEM foam. Got a Walbro 460 to put in. Probably going to add a relay to give the pump a solid 13volts. Replacing all the fuel hoses, in tank etc.

-Front drive shafts still not back on. Waiting on parts. Would like to buy some new ones, but probably going to patch these up for now

-Replacing gas struts on back door. Waiting to be returned

-Headlights need a polish/repair

-Going to touch up the paint a little.

-Clean up the interior

-Connect up heater plumbing

-Cosmetic stuff, powder coat replace rusty parts, replace rusty bolts, wiper blades, silicon missing rubber

-A million other things

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
