    Default Fel-Pro MLS?

    Assembled a motor using a set of Fel-Pro PermaTorque Multi-Layer Steel Head Gaskets. Fired it up, ran for 3 minutes, found a leaking valve guide, shut it down and pulled the motor apart. Ready to put to back together, question is, can the head gaskets be re-used or do I need to get new ones?

    Spray them down with spray tack and re use them Pat.

    You have to be carefull with the term MLS. Seems Felpro like to throw that term around when refering to composition gaskets as well. If they are blue, there aren't MLS, they are composition. MLS gaskets are black and sticky as hell. http://store.summitracing.com/partde...2&autoview=sku

    you can reuse them as long as the coating wasn't damaged during disassembly. if the coating came off onto the block or head, use some copper coat spray to recoat the gaskets, let it fully dry till its tacky before reinstalling.

    Dare to be different, if it turns out great you can claim you planned it that way.

    The hot set up is Mopar #VOU 1508 spray sealer. 71 Hallett turned me on to the stuff. Seems some guys even sray it between the layers.

    See....I am only part idiot.

    Like GN7 just posted this is the best to use and between layers is ideal.

    We have used the Fel Pro MLS many times. I had to remove a head that was torqued but never run. Fel Pro said DO NOT re-use the gasket. When I pulled the head the tacky surface was compromised so I would not re-use them. Just my experience.

    Seems my good buddy 71 Hallett may have given me a bad part #. Maybe it's a Canadian number? This is the number I used P/N 04318035 and a link to a service bulletin on MLS gaskets.

    I can't see how they would still be good. I have installed many sets but never taken heads off after they have been run.

    Leaking guide? The strangest thing I have ever seen is a BBC guide completely eaten through where it goes through the water jacket. But looks perfect everywhere else. The only way to detect it was a pressure test.
