Reinstalling Gaskets

To anyone who has done engine work or replaced gaskets what is the procedure I should follow. My whole engine is broken down and my new gasket kit arrived in the mail. Do I need to dip gasket in oil before place it or silicone or anything like that or do I just place it and screw the pieces together?

I have had good luck with cleaning the mating surface very carefully with a razor blade and then wiping it clean with some alcohol on a rag. If you use silicon only use a very light coat on both sides of the gasket. When I had my engine torn down I used spray gasket adhesive to coat both sides of the gasket before compressing it between two pieces. The spray gasket adhesive is made by permatex and can be purchased at any auto parts store. I like using the stuff because it is not messy and it provides a great seal once the pieces are together. When using silicone it blobs out of the gasket and just makes a mess. Of course there are some exceptions to using gasket sealants on some gaskets. Some gaskets to install dry would be something like a head gasket.

If you do use RTV, after the engine assembled, run it for a few minutes and change the oil filter. No reason to have silicone clogging up the oil passages.

I have done it before on my own bikes, but never to a customer's bike. Prior to even gasket sheets becomming avaliable after WWII I was great in using brown paper bags or brown wrapping paper for gasket material on a few of my bikes, but we are talking about pre-war Harley & Indian bikes with all of 24hp in said cases of brown paper bags.

With the Brit irons I found out most required a new head gasket though in some cases all I had to do was heat up the bronze head gasket-----ah the good old times!!!!!!! LOL

some gaskets its ok to use silcone sealant with but just a small amout , do not use any sealant on cork gaskets. look in the book and see what it says on the head gasket some say use a sealant with and some say dont. i find that if you are usuing new gaskets and are torqueing the parts when you assemble them you dont need any sealant , sometimes sealants will do more harm then good. the stuff you want to use is called high tac it is a spray and will be ok on new gaskets. i work in a shop ( auto ) as a tech/shopforman just a title hehehe means nothing, but i do have alot of experance doing engine work if you get in a bind call me at 207-487-6324 ill help if i can.
