    Valve cover gaskets

    In the middle of stripping valve covers on my 65 mustang conv. 289 c. Question is upon install with cork gaskets, do I need to put gasket sealant. If so on both sides of gasket?

    Re: Valve cover gaskets

    I use a light coat of spray adhesive on the valve cover to hold the gasket in place during install.  The gasket should seal properly without additional  sealer.

    Re: Valve cover gaskets

    Seems to be a duplicate post, but I'll add this anyway.  I've never had much luck with cork gaskets.  They all seem to seep oil.  I started using metal core rubber gaskets on everything years back and no more leaks.  They are more expensive, but not needing sealer or glue are also reuseable.

    All true...and, they raised my aluminum valve covers enough that there is no interferance with the Scorpian roller rockers.

    Re: Valve cover gaskets

    I have some extra thick cork gaskets that also provided additional clearence for my roller tipped rockers. I glued them on to the valve cover with contact cement and I put a light coating of grease on the side contacting the head. They were on for quite af few years with no leaks. When I had to pull them off to change valve springs, they came off easily. I reinstalled them and still no leaks.

    Re: Valve cover gaskets

    What I have done on some aftermarket chrome valve covers that do NOT have the tabs to hold them in place like stock factory ones,  I put silicone on the top side between the cover and the gasket.  You MUST let it sit overnight to completely dry.  If you use silicone in places like valve cover gaskets and oil pan gaskets (especially chrome)  and install it while its still wet, it can and will squeeze the gasket in or out.   I found this out the hard way.  

    If multiple things can go wrong, the one that will go wrong will be the one that causes the most damage.

    BB & TKO - I'm interested to know what brand & part number are the gaskets your are using?

    jon5014ren - I use Felpro #FEL-VS50029C, this is a cork gasket w/steel o-rings to prevent over tightening, w/no sealant.  I have Cobra valve covers w/Competion Cams roller rockers.

    Re: Valve cover gaskets

    I use weatherstrip adhesive to glue the cork gasket to the valve cover, then use that brown shellack stuff by permatex, I think its called 3H on the other side of the gasket. Or just do what TKO said and get the metal core gaskets that don't need any sealers.

    Re: Valve cover gaskets

    Over the years I've used both Fel-Pro and MOROSO on various makes/models.  I know this is a Ford forum, but I own and work on everything from Subaru to Chevy to Ford to AMC, etc.  I generally look for the ones I can find in black, as I anally hate having blue gaskets on a black or red engine.  I've been using one piece oil pan gaskets with the same construction for a while now too, and they are much better than the 4 piece ones.  Gaskets, like most stuff I feel you get what you pay for.  I don't mind dropping $30-$50 on a set of valve cover gaskets if they don't leak and last essentially forever.
