I had a good look underneath the car today just to check for any problems and came across evidence of a small leak.

I'm unsure if this is a common thing on the M35's but just looking if anyone can help give me an idea where this leak is coming from.

From what I can see, it looks like it might be coming from loose hose clip.

The leak doesn't seem major, and there's no drips under the car overnight so far.

Looking at sorting out the leak, if anyone has any idea or can help, your input would be appreciated :)

Small leak? :down:

It could be a few things, most likely the rear of the passenger side rocker cover, they are well known to leak from there. Fixed with a replacement rocker gasket.

It could also be one of the plug hole seals, mine had completely filled the rear plug and spilt out under acceleration. Fixed with a smear of silicone.

Hopefully it isn't the oil inlet for the turbo, its a pain to get at. Can you see oil weeping from the top? See if you can get the camera in there.

Thanks Scott.

I've inspected the rest of the engine bay as much as i can but couldn't trace it any further than that clip and where the arrows are.

I can't see anywhere else where the leak is coming from besides this part.

It doesn't seem to be leaking much (as in there are no visible drops on the ground yet). The car should still be fine to drive for now, right?

Hey Dimi, you picked it up last week so it's still under warranty. Take it back and ask them nicely if they can rectify the problem? You didn't pay for a car with an oil leak so they should have no problem fixing it for you.

Hey fellas, appreciate all your help! :)

I think it is engine oil.

You might be right though. They might have fixed the leak already because it doesn't seem to be dripping at all.

So what i'll do is degrease it and sus it out after a good 100kms worth of driving. If the leak persists, i'll contact the dealer and ask them if they could rectify it. They should be cool about fixing up the leak, right?

I might give them a call today at lunch and ask them if they sorted out or noticed a leak before.

Okay, so i degreased everything and took it for a good 100km drive.

I can now see more clearly where the leak is coming from.

The leak is there and i can smell it when the car is at idle with the fan on.

It's at this odd location just on top of the turbo.

What are your recommendations on this? Take it back to the dealer and ask them to help me rectify the leak? I've only had the car for 7 days.

My car is leaking slowly from the same spot, it is the rubber rocker gasket by the looks of it. They will probably order one in and fix it, you could of course get it yourself and fit it if the dealer isn't local.

I would change the plugs while you're there if they haven't been done already.

Yours is doing the same thing?

I see. Well at least i now know it's not an "impossible fix".

It seems like a slow leak on mine too.

How long has yours been leaking for Scott?

pretty sure they have to fix it under the statutory warranty that you get from a dealer - 1 month and 5000(?) kms i think

How it passed a roadworthy with that much oil underneath, I have no idea.

I fixed mine myself as I didn't want the dealer touching anything else on the car... I should have bought a new seal though, instead I used silicone and it only lasted a few months.

Thanks fellas. I called them and they were nice about it. I'm going to go there this afternoon to have a chat then i'll leave the car with them on Sunday afternoon. Hopefully it doesn't take long to repair.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
