Reusing gaskets?

.

And don't pre-oil paper or cork gaskets like you do w an oil filter.

Also, they should be (must be) used w a gasket cement. I like Indian Head brand, but others are fine too.

Thanks for the tips so far guys.

Soundguy - the Canadian Tire stores up here carry various Permatex products but most seem to be gasket makers of some sort.

The closest thing that I could find from Permatex here that could qualify as general purpose goo for gaskets is this. It says it eliminates the need for pre-formed gaskets so I don't know if you can use it in addition to an existing gasket.

Your Kabota dealer should be able to tell you if it is a rubber gasket. When I said glue I was refering to gasket sealer. If you have a rubber gasket dont put anything on it. If you have paper or cork use a gasket cement/sealer.

Canoe, I wouldnt use the stuff you listed. THeres no link to the actual permitex product, but it sounds like 518. Thats usually used on machined surfaces without gaskets.

If rubber, just leave it where it is and reuse.

If paper, leave it where it is and put some gasket cement on the pan flange and bolt it back in place ( use something like aviation form a gasket from permitex. available at Pauto and cdn tire i think)

Or remove all the gaskets and use this http://www.permatex.com/products/Automotive/automotive_gasketing/gasket_makers/auto_Permatex_the_Right_Stuff_Gasket_Maker.htm

I no longer make or buy pan gaskets since discovering "the Right Stuff". Best gasket ever:D And it even comes in a spray cheese can:eek:

Gotta tell you, I am really impressed with all these spray on gasket products that are available. I went to Princess Auto today and I was amazed at the variety. They had ones that were sensor safe and so on.

I'm pretty sure the one I've got here is rubber so I guess I will reuse dry. More than anything, I think I'm going to reuse because it is perfectly aligned and it really does seem to be in good shape.

Not all paper gaskets get goop.

ford N hyd top and bottom cover gaskets go on dry.. goop makes the gaskets blow out... it's 1700 psi and 2 metal plates bolted to a casting with an oil hole.. and a gasket as thick as a sheet of typing paper inbetween.

normally use new only. if you don't you are going to have leaks and be redoing the job.

paper only reuse if emergency or nothing else available, with Permatex.

rubber ok if not stiff and overly crushed. if you have to reuse it, then use a little Permatex on it.

My 2 cents on all of this. It is hard to tell without removing a gasket if it is rubber or rubberized paper / cork

If you use RTV (Gasket in a tube) don't go hog wild with it. A drip inside your oil pan might plug something useful.

If you remove your gasket, inspect both metal surfaces and clean of any residue before applying new gasket or gasket seal. You can use a metal paint scraper to get it nice and clean.

I reused the rubber gasket and did not put any goo on it. Everything looks good. No leaks noticed so far.

Thanks so much for all the thoughts.

Good choice. What has not been mentioned here is that silicone sealant in contact with the very slightly oiled surfaces of an existing gasket and pan [in your case] will fill any small imperfections and form a release agent between the two sides of a joint. In subsequent removal the gasket will be more likely to stay on the other side. You use a very thin layer - just enuf to feel the stickiness when you spackle it on with a finger. Low pressure gaskets are good for repeated separation of the joint for the life of the engine with this treatment.
