It's not the cam cover gaskets that are the source of the filled plug wells - there are hard rubber "grommets" that cap the plug well tops to the cam covers. Unless you are talking about an exterior leak, these are the culprits.

They run about $14 each (x6) at the dealer, so here's a temporary fix, that should last you 5k to 10k miles - RTV the grommets. What I just did on my non-running 91's was, pull the cam cover, carefully remove the grommets, clean them up, RTV the grommet to cam cover seal area, replace the grommet, then RTV the grommet to plug well surface (on the grommet). When you replace the cam cover gaskets (reusable if in decent shape), remove the old RTV beads & re-RTV in those sharp corners.

a couple of bucks for RTV vs. $90 for grommets. Again, this is a temp fix, and not "the right way", but it'll get you through the winter nicely. Good luck Jason.

If you decide you are going to replace the cam cover gaskets as well, look at the upper gasket set from SHO Nut. Cheap in the long run, & you get every gasket known to man in it...

i know where ur coming from man. I got oil in my plug wells. They are filled and sometimes the wires are pushed out a little. I think not all of the plugs are firing due to all of the oil. This week i'm cleaning them out though. I'm putting sealant around it so that'll fix it. I can't wait to get them done and see how my car performs. The sealant will only cost me like 4 bucks or so, so it'll be sweet. Good luck on yours. Late

As Fred said, you can use RTV (room temperature vulcanized) silicone on BOTH sides of the grommets to temporarily seal the plug wells. The real fix is to replace the seals. The last time I priced them at the dealership, they were $30 a piece! They are part of the Fel-Pro VS50738R set ($72 AutoZone, $92 O'Reilly, but they should match AutoZone) that includes the valve covers seals also.
