4.0 SOHC Valve Cover Gaskets

[JohnnyO]

2008 4.0 SOHC Sport Trac. Driver's side valve cover gasket is leaking. It looks like I have to take off the top of the intake manifold to get to it, which at my skill level I think I can do. I have not had to change valve cover gaskets in decades. Do I need to use gasket sealant or do they just go on plain with nothing else? Rock Auto lists about 6 different gaskets from $6 to $14 a pair. Is there any one that is the better kind to get? Thanks in advance.

If the aftermarket set is the same as the factory gasket (molded rubber) you do not need to use any kind of sealant.

I always use Mahle or Felpro.

Get some new plenum gaskets, too. The plenum is the upper half of the intake manifold, by the way. I use Felpro as a first choice, too.

Okay, thanks. Rock Auto lists Mahle and Felpro both. I didn't know the upper plenum had a gasket, it's something I never took apart before but then I never kept a vehicle for over 200,000 miles until now either.
