Gaskets for valve cover, valley cover, or pan gaskets is this reasonable? thanks tom | | | | | Joined: Feb 2006 Posts: 549 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 549 | I use it on the ends of the intake on a V8 but wouldn't consider it on the pan or valve covers. | | | | | Joined: May 2005 Posts: 8,878 . | | .

I often use permatex # 2 with a gasket, but nothing replaces a gasket.

A sealant will be a very temporary fix if it works. | | | | | Joined: Feb 2000 Posts: 5,228 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,228 | Yes with the right sealant. http://www.permatex.com/brand_right_stuff.htmThis stuff will hold anything, and you will bend the covers getting them back off if needed, its that strong. It works just as well with gaskets to. Don't get it on you, it takes a while to wear off!

Joe And how exactly is that a good thing?  | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | .... I agree with Joe H. guys. Unless your a mechanic you will not likely to ever have to pull a pan, or intake, off in our lifetime if we do the job right and while we age the chance of leaks all over the drive way or in the garage are lessened.
We've used it on racing engines and once the pan is in place you get pretty good after a while wiping the edge of the pan to leave a pretty and smooth seal that will withstand a lot!!
I DO use gaskets and I usually make individual choices on different jobs.....
Just my .02 | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | Pans and covers that require a liquid sealant are designed differently than gasketed surfaces. A liquid joint needs a groove in it to act as a bead lock to keep the sealant in place after its cured. Flat, smooth sufaces require a gasket. Also, some gaskets are a factor in clearances between the two parts. My 2 cents, use a gasket when a gasket is called for,

theres a tool for every job,and that tool is a hammer. it's easy to give advice if it's not your pocket book at stake. A well thought out plan,Is nothing. Untill exacuted twice.
