250,000 miles valve cover gasket replacement

My Sr valve cover is leaking oil around spark plugs and you can see signs on out side the the outer side of cover where it collecting dirt. When I changed the plugs at 100k there was no sign. I think I'm going with factory gasket I heard of people cracking the valve cover with the felpro gasket set on earlier models. Don't want to take a chance. Anyone think otherwise? Or have done it? I know I'm the few people that put this many miles on a 3rd gen. It will be my next Sunday project.

I'm always a fan of using OEM whenever possible unless there's an obvious improvement to be made. In this case, it sounds like you've certainly used it well.

 

My bro has a first gen and I recall the consensus is to use OEM gaskets. I would play it safe with using OEM ones.

 

I would have a hard time justifying aftermarket if you got 250k out of OE.

 

OE only i've had nothing but problems with some Felpro gaskets

 

curious if you’ve had any other leaks or major problems so far. I just cracked 100k a couple days ago. The only thing on my truck that leaks is the timing cover, but it’s not terrible.

 

Nope this is first leak I would of not known if I didn't change the plugs. All I seen is just residue on out side where it meets the cylinder head

 

I'd stick OEM; 250k sounds about right for most vehicles to start leaking.
