Ok so i have had this ticking noise, not a knock or a tap, a tick, like as if you were listning to an old grandfather clock, except faster.

The car has done 80K, and has always been serviced even in japan, i got all books and so forht. The engine has good compretion 150psi across all cylinders. Engine makes great power over 200 rwks, and is always warmed up and cooled down.

It does not blow any smoke or use oil or watter.

Now i know the tappet tap, i can hear those, the injectors are noisy, common issues, no probs there.

But this sound can only be heard under the car, on teh turbo side, and possibly towards the rear, hard to tell. it's a faint tick. You can only hear it under the car, and if you are driving slow in a carpark. I do not know if it gets lowder when you go faster, cos it is faint.

I think the sound is the same on cold or hot starts, i think. I have tried to listen with ahose to see if i can pinpoint the noise but no good.

Now i have did find two louse studs on the manifold did these up. so far i have not found any other. The manifold sustds are all there.

The clutch throw out bearing has been replaced, and sounds fine.

No i don't know what this can be, as it can ONLY be heard under the car.

Can someone with a simmilar problem give me some ideas ????????????

What are teh signs of a big end about to spin?????

HELP I am going to go insane i am to anal about cars. LOL

Yea i've got the same problem... would be good to know wtf is it...

exhaust gasket is farket or turbo gasket is gone i had same problem on a ca18det ticked and went like a dog fixed the turbo gasket and gone like that just a thaught

cause if two studs were loose its probably damage

the gasket

yep, just the gasket as above.

Nothing major, and pretty common issue.

Make sure you replace it, and ALL of the manifold studs/turbo gaskets at the same time so it doesnt happen all again

but the tubo pulls great, boost like there is no tommorow, i wish i could recod it.

I am going to go over all the agskets to have a look.

so does teh gasket cause a fain tick, tick tick????

well i went over the car, and well no ticking when cold, only when hot. Went over all the bolts, all tight. I think it's the manifold, as when you close the bonnet, its a bit louder.

Dam it.

yepp taht trick is the one i used, my dad told me how to use it properly, works dam well too.

I have checked the oil pressure, all fine good oil pressure, new oil, and the ticking noise can't be heard anywhere on the engine, not bearings, not block no idea. so i think its must be my exhaust.

ohh well wait till it shit me too much.

My internal wastegate made a similar noise when I got a hi-flowed turbo. So I just bought a tensioner and welded it to the actuator rod to put more tension on it, worked fine and adjusts boost (like the hks items). Probably not this as you haven't changed your turbo but something to check none the less.

I'll tell you now I had that same noise. I recently got my GT3076R turbo on my car and in the process they changed manifold bolts (heads broke off and screws stuck in thread), manifold gasket (that was completely f**ked to high heaven) turbo and a few exhaust gaskets and the ticking noise was no longer an issue.

Thanks guys, yeah i am sure it's an exhaust, i found some black burn marks arround, evidence of exhaust leaks.

I wish i got my warranty now. LOL. Oh well, looks lika a weekend job.

Gettign some pricing today, but where is the best place to get manifold gasket from. nissan is about $100 i think.

It'll be a few hundred very quickly

* All manifold studs changed out

* Manifold gasket

* Turbo & Dump gaskets

Also note, your more than likely going to snap a stud or two. Its just the nature of the beast.

Use LOTS of WD40 or similar a few hours before you start if DIY from home.

If your paying a workshop do to it, its going to be close to a 600-800 advanture i reckon by the time its all done.

are the other ones shit or something?

I have heard that Sparco have good ones.

How do i tell if it is a good one? Anyone have had bad experiance with non genuine ones or something?

Thanks R31nizmo, but i'll be doing all the work myself, this is a piss of piss compared to some of the jobs. Allthough i am only a mechanical engineer, having worked on car's since i was 9 and dad did rallying in Europe, this is nothign new.

Well new in the sence that it is a Skyline, and haven't delt in turbos before, it's a bit more complicated, hence the barage of questions.

I have the manual and all the tools, so i figured i can't stuff it up to much. LOL. here's hoping anyway.

So far costs are

Exhayst gasket manifold = $100

turbo to manifold = $ 15

turbo to dump = $23

Stud kit and new nuts and washers = $38

Also will replace copper gaskets on teh turbo, but have not got price as yet.

Total = $176

Hideen charges

Beer = $30

Bandaids = $5

Trip to doctor for scuffed knuckels = $30

Knowing you did it yourself = pricless.

LOL

thanks guys.

    • 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.
