Front Oil Cover Leak? Easy Fix? *PICTURES* - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

when we put my motor back together we forgot to put the rtv on the front section where the oil pump assembly is, and its been leaking since.

if you cant afford to pull the head off and do it right, then just leave it alone. any way you look at it, it costs labor. if you can do it yourself and you think its worth the time then figure it out, but for me personally i can deal with the front cover being dirty rather than pulling the head off. ill just wait til the next time i remove the head for whatever reason it is. the engine runs fine. i add about half a quart of oil midway through oil changes.

wow you guys are making this hard. you dont have to pull the entire cam, thats just a waste of time. like everyone else said.

remove lower and upper oil pan sections
remove crank pulley
remove valve cover.
remove exhaust cam gear(ziptie gear to chain to not lose timing)
remove tensioner(helps to get the gear back on with the slack)
remove the stupid 10mm bolts that connect the head to the timing cover

DONE. shouldnt take more than 30 minutes IN THE CAR.

installation is reverse obviously

great time to change the FMS. ive found it pointless to put rtv on the top of the head gasket since the head covers everything at the top most point and have yet to have a single problem.

The grease seems thick and appears to have been there for a quite long period of time. The wet spots are just some Mean Green that I sprayed on it planning to clean the greases off.

At first, I thought the head gasket was leaking, but after close examination, the grease seems appear around the front oil cover. It seems that it needs new RTV. Is it easy to remove it? Do I have to take off the head to have it removed?

Thanks. Much appreciated!

Good afternoon,

I have exactly the same problem, could you please tell me if you finally solved it by changing the o-ring?

I would really appreciate it if you could help me.

Thank you very much for the help.
A greeting from Spain.

Have you considered the front main seal to be the problem? id replace that first before anything, seems like every Nissan leaks there
and definitely clean that stuff off so you can get an idea where its coming from it doesn't look to be oozing out the timing cover.
it really doesnt even look like th oil is leaking from the cover, it looks like dirt and oil are being thrown there

Its most likely front cover oil pump.... It just gets hot and leaks. Nothing you can do about it on an old motor.

Good luck
