leaking slight oil from Valve Cover

megalapagas · 07-09-2014, 06:55 PM

As the tittle says it looks like if someone spit oil down to the headers heat shield and everything else around it (Just very minimal nothing exagerating). My question is can I just pour in a Oil Leak sealer? Also why does this happen, why does the valve cover gasket get shot? Its my DD with some spirited driving, I'm to the point where I just want to rid of my car, changing the gaskets was a hastle last time I did em.

First thing to do would be just to tighten down on them if they are loose. I need to take a look at them. I have to ask, did you put RTV everywhere? It is only needed in certain places if at all.

Re-torquing the fasteners may do the trick.

I don't know your skill level so no offence, but did you do it right? The gasket shouldn't fail if installed according to the manufactiurer's installation instructions i.e. the gasket should last quite a while. Leak sealer could work but the best fix is to determine the cause and repair/replace as required.

I wouldn't touch that leak sealer type stuff, if you mean the kind you add to your engine oil. Especially not for a relatively-superficial issue like a valve cover gasket.

jwick · 07-10-2014, 11:46 AM

Where exactly is the leak?

1slow370 · 07-10-2014, 12:45 PM

a freshly installed valve cover gasket shouldn't leak, key things on the vhr gaskets for proper install is to make sure the old silicone is gone, and to follow the instructions in the manual on how and where to apply new silicone, and to follow the torque sequence. the gasket is pretty thick so when you tighten it down it is possible to tighten it on an angle which is bad for the gasket.

I don't know if OP means the last time he changed valve covers on any car, or on the Z...

1slow370 · 07-10-2014, 03:46 PM

he changed his valve cover gasket pics are in his nitrous thread

megalapagas · 07-25-2014, 03:54 AM

Well haven't had a chance to update lately and check on my Z...valve covers are fine no oil leaks but I did found this though^^^^ Do Our motor monts have fluid in them??? <'--Dumb question but its worth a **** and I'm about to check if I have an oil leak on my oil cooler lines after this is posted.

1slow370 · 07-25-2014, 04:19 AM

the mounts are liquid filled but it doesn't look blown, most likely oil from somewhere else like the fittings or sandwhich plate seals if you have an oil cooler. you might just need to take the filter off and tighten the nut that holds the sandwich plate on.

Edit: also thats not slight oil thats a **** ton of oil

fuct · 07-25-2014, 09:03 AM

^^^exactly! thats not a little oil man!

1slow370 · 07-25-2014, 12:39 PM

hopefully not too much of it got in the alternator, it tends to make dirt stick and the dirt can short stuff if it gets run around in there.

Well as you can see started digging more down took off the undershroud (slightly difficult without jack stands but do able) and yea undershroud was pretty much filled with dirt and some oil....I was able to clean the alternator which was my main concern though. So in order to fix this leak before I go running on to my local autoparts store and buying a leak sealer hahahaha jk jk jk...what is needed? O rings?? Or whatexactly? And in order to fix this I will have to drain my oil correct in order to do it?
