Oil cap leak fixed

raywong · 01-12-2013, 05:49 AM

many people complained about oil seeping out from the oil cap. I had this problem and here is my fix.
Pull out the rubber gasket ring, wash it really really well. Clean the cap, the cam cover opening really really well. Reverse the rubber ring and put everything back carefully without any contamination. No more leak!

He is referring to the rubber ring that is on the cap, remove it...flip it over and reinstall.

I just replaced it with a new cap... it was 12 bucks. No more leakage.

The first time I cleaned it, I only used a wet towel to wipe, leaking actually became worst. I searched the Internet and found out many people had bought the new version oil cap and still had some leak. I think the rubber gasket is too thin, any dirt trapped will cause a leak.
I washed everything again in a bucket of water, and wiped the cam cover clean. No leak so far.

Going to try doing that...

I have had the new cap since it came out, and it does leak occasionally. Wiping off the rubber ring seems to help.

New style cap doesn't fix mine, will give op's method a try.

When this topic has been brought up before, it's been hit or miss as to whether the newer cap really fixes it or not. I know there was a user who doubled up on gaskets to try and seal it better. Bottom line, don't count on the new cap to fix anything. I have the newest one and it still leaks.

How come I've had the car for five years now and haven't had this issue. I had the occasional weeping which I don't know was after an oil change when the dripping had occurred. It's is just puzzling that a lot of people have this issue seriously.
