Leaking Oil Cap

[texasjack]

Has anyone come up with a method to stop the plastic oil cap from leaking on the plastic 4 cylinder valve cover?

I purchased a new cap and it leaks, installed a second gasket it leaks.

I was thinking about removing the tabs from the valve cover and using a expandable rubber freeze plug with a wing nut to tightened it.

Any ideas will be appreciated.

 

Thank you

sounds like to much pressure and your breather is clogged.

You likely have blow-by, crankcase pressure, you'll never get it to stop leaking. 

 

I suggest an aluminum cover from a 90s Wrangler. 

 

There's a 90% chance you'll destroy the cover taking it off, they get brittle with age. So, the chance of you altering/modifying without damaging the cover is slim. 

 

Plastic is still available, if  you want a plastic replacement, I suggest having the new one before you remove the old one.

 

 

 

 

 

My setup is a little different now but this was the replacement-

Note the absence of the little lugs on the bottom of the cover where the gasket goes, I ground them off, the blue Felpro gaskets fits much better, no leaks. 

 

 

Lugs are shown here-

if it doesn`t leak, it`s not a Jeep
