1990 convertible.
Looking at the valve cover, the bolts look like they had some o-rings or gaskets that need some love. I’ve found felpro options for 93 and newer - unsure if there is a better option or if these are necessary at all. Photo attached.
also looking to replace the PCV valve/gasket as there’s a small amount of oil leaking from this point. Any advice is appreciated. I’m new here to all of this. Photo attached.
Looks like somebody has put some kind of sealant around the valve cover bolt.
Normally it's just a metal washer under the bolt head, but some people will also stick an o-ring or a rubber washer under there s as nt to mess up the paint.
The PCV grommet you can get from Zip. They have the right sized ones and they're nice and tight. I just replaced those on my '90, in fact.
Thoses ones on RockAuto or wherever else are all different inside and outside diameters for whatever reason.
