Valve cover gasket was changed by chevy here about 7000 miles ago by previous owner. Already seeping a little. I'm going to change it myself to make sure it's done properly this time. Here in Uruguay the mechanics rarely use torque wrenches and follow specific torque sequences.
I assume they just overtightened it or didn't clean the surfaces properly. Very common here.
Now what would be a good brand? Chevy sell cheap replacement gaskets here but I'm skeptical about their quality.
Heard good reviews about Fel Pro in usa. Are they worth the 40 odd bucks or should I just go with a cheap replacement from chevy here? Should I add a little gasket sealant with the gasket for extra security?
Thanks in advance
