Hi fellas, lots of good information and smart people here so i had no choice but to join :P .

I have a low km R32 RB20Det which has started to tick even when at operating temperature. The sound is coming from above the rocker covers so i'm thinking tappets (i don't mean the the injectors ticking).

Last night my oil gauge wouldn't budge much off 0, i checked the oil level but it looked right on the money. Engine was still running smooth on the way home and the gauge stayed at 0 but occasionally rising a little bit. I read in other forums that a seal is usally the culprit and the gauge is probably not reading properly.

Anyway some VX Calais pulled up at the lights and wanted a run so i thought bugger it, lights went green easily took him but wooot the guage went back to normal. The thing that still worries me is that tappet noise though.

When i did a service (4300kms ago) i couldn't get the oil filter off (I've never had this prob before with other cars) so i decided to leave it and just replace the oil. Car drove fine and no ticking was evident until the last few days.

Could this be the culprit? I used Penrite HPR 10 10W-50 Semi-Synth.

Thanks.

Thankyou for your suggestions, what i was thinking is since the filters probably had around 10,000+kms (guess) the filter might be restricting oil flow?

Before i did the service i had a leaking oil crank seal which i replaced along with both cam oil seals. Leaking was due to low oil and thrashing when i first got the car. Once fixed the car felt like a new again and no oil leaks!

I have 2 different oil filter wrenches, 1 chain and 1 strap type but both didn't want to budge it. I was going to just stick a long flat head screwdriver through the filter but wasn't brave enough.

I'm not going to go against your suggestion xr8eater but this oil doesn't seem too bad at all, when i checked the oil the colour and viscosity looked like i just filled up.

Although when i start the car when cold i hear a clacking sound for a second then the engine revs up and settles, the rocker rattle sounds more like a mis rather then a constant rattle.

I usually solve these types of problems in time, but thought someone has had a similar fault here and could save me a bit that time.

Thanks.

i am going say it even though people will dissagree who use that oil

dump it and get some turbo light

Just read a thread agianst Penrite oil on this forum and your right, but have I damaged my engine?

I'll get the new Motul oil and filter on tomorrow thanks m8.

i used that oil once and never again

it dident do any permanant damage but took almost two or three changes before it was running right. make sure you use the valvoline filters or standard nissan filters as they have the best filtering applications for skylines that won't brake the bank

If all else fails check your zorst manifold it may need tightening. just a thought

i use that oil with no problems :confused:

as for the sound... maybe the lifters aren't getting oil into them (ie some sludge or something lodged)

try some "oil flush" on your next change

oh, and its been said buti have to say it too... change your filter with the oil!!

cheers,

Warren.

Are you sure its not just the injectors? Nissan motors especially the SR20DET have shockingly loud injectors. The RB20DET does as well, just not as loud. Stick your head down there to see its them pulsing....

If it is them, its normal...

M8, it's not the injectors it's a light rattling sound coming from above the rocker covers. Injectors have a distinct sound and that sound isn't what i'm worried about.

Is it definately a clicking noise or a 'miss'? If its clicking I'd agree with Waz, if you change the filter tho and it's still clicking perhaps they need to be adjusted?

I left the old oil in and simply changed the filter yesterday. Within the next couple days i will change the filter again and fill with Motul Turbolite. The clicking or rattling sound is fairly light not that loud.

My oil gauge started playing up which then led me to check under the bonnet and hear the lifters. Today when i first started her up the gauge read just above 4 (i thought yippee), then gave it some stick and the gauge went back down to 0.

I'm thinking about using the engine flush with this old oil before refilling but not sure if it's a waste of money or if my oil pump is on it's way out.

This kind of thing shouldn't be happening to a car with under 100,000kms so i'm stumped.

Nulon make an additive that it claims can clear the lifters (presumably if you get them early enough).

So, try an oil AND filter change (it is possible to get the filter off with the strap type wrenches that have the screw down the middle). Even leave it draining overnight to get as much as possible of the old oil out. Add some good quality 10-30 synthetic and the Nulon (it's called something like "Lifter Clean" - very imaginative!)

It may be nothing to do with the lifters.

When I had a SR20DET Silvia, I used Magnatec once cause I was poor one oil change. The engine made a racket, sounded like a timing chain rattle, never actually found out what it was but it sounded seedy.

I dumped it, went back to mobil 1 and it was fine. Bizarre.

All this torque of injectors blah blah...

Have you checked the oil sender unit as this seems to be part of the problems. As for the rattling it could by the hydraulic lifters. Use caution when using an oil flush as I have seen some cause oil starvation and piston rings collapsing.

Run a full sythetic, Motul Turbolight is a semi, I would recommend using this for the flush only, then go for something like the Pennzoil Full Synthetic or Mobil 1 or even Shell Helix. Also after the flush run another lot of oil through it before putting the final through. Sounds pedantic but may save a rebuild.

The only reason for the gauge not ready when warm may be that when the oil warms up it gets thinner and for some reason the pressure sensor is not reading properly. this is a common problem I would be getting an after market gauge preferably mechanical to test the actual pressure, not these these are dangerous and should not be installed in cabin and thus only be used under the bonnet in the garage or where ever you are working.

Ok the sound is not that loud though and the engine is low km so it shouldn't need a rebuild anytime soon.

The noise is a light tapping sound which it didn't do before and at the same time my oil gauge is acting up so i thought the old oil filter is blocked. I've changed the filter that i couldn't get off with a new one and have run 50km using the old oil. I won't be using the engine flush, i'll just purchase another oil filter and either Shell Helix or Motul Turbolite.

It was suggested to me in a private message that i should change the oil and just replace the filter 4-5 times using the same oil, then changing the oil and filter again the last time.

What i'll do though is change the oil and filter tomorrow and if the tapping goes away i'll leave it at that and change the filter again after another 500kms.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
