valve cover gasket still leak after replacing

[chiihoong]

I just replace my valve cover gasket and spark plug "o" ring due to leaking at the #4 cylinder spark plug. Few weeks later, i found out that my car does not have a good idle. I saw #4 cylinder spark plug is still leaking. Can anyone help me with this problem? What should i do and what cause the problem? Thank you!

Simple.... just remove and reseal the gaskets

u bought the gaskets yourself or your foreman bought it?
could be el-cheapo ones.

Especially important parts needs original. Others at least chop shop, or recon. Cheap parts better not....

i think cheap parts can still do.. non important parts maybe like gear knob, carpet, door visor etc... but still depends on the owner..

mine has small leakage around the cam sensor.. maybe the o ring..

sometimes if you don't torque it right it'll still leak. And certain valve cover gaskets have a direction (up vs down). Incorrect install and it'll leak too. If plug 4 is being affected like that you might have a issue with the valve guide?

I hope the engine sealant was not forgotten on the o-ring for 4th cylinder. It's like a grey toothpaste.

Some use just as a guarantee, instead of taking it out again....
