Engine gasket installation

Post by Kevinstonge »

Hey guys, just curious if there is a secret or better way to install paper gaskets for metal to metal surfaces so that it's easier to remove when changing the next time.

I've had a couple ch80 engines apart recently and realized every time I've disassembled one in the past I've had a b**** of a time removing the paper gaskets( usually with a razor blade, sand paper, abrasive scrubby) I've always installed them dry and on super clean surfaces. Also never had one leak on me with this method. I guess if I HAD to choose I'd rather have a b**** of a time removing the gasket and have no leaks, than have a seeping gasket that's easy to remove..

Any comments are appreciated.

Greetings:

I always slather a generous amount of Harley-Davidson Hi-Temp Multi-Purpose grease to both sides of the dry paper. Any grease will do, but this is what I've had on hand for almost 15 years... This serves three purposes:

1. The gasket is rendered a bit tacky and so stays in position better when you start fumbling with mating parts and fasteners,
2. The gasket starts soaking in Petroleum right away and from all sides instead of soaking it in from the "wet" side only. You can get away with less-than-perfect mating surfaces if the gasket is moist and pliable and the grease pre-fills the defects.
3. Best of all, when it's time to take it apart, it splits like Buttah. Sometimes so easy that I can re-use the gasket.

Your mileage may vary. You don't have to do this. It's just what I do.

Thanks sir wheelman. I have heard of using engine oil on the gasket before installing, but I was skeptical of doing so. I like the hi temp multi purpose approach. Much appreciation my friend.

Ive used hi temp brake grease it has worked well. I have been using my ipone synthetic 2 stroke oil because its there in my oil can for assembly and it has been working extremely well also. As wheelman said the grease does a great job of holding the gasket in place during assembly. So sometimes I'll soak the gasket in 2 stroke oil and use grease to hold it from sliding around :-)

Copper spray is awesome for paper gaskets on the engine as well. I use high temp grease per wheelmans regime on them if there isn't any copper spray available.

I'm not familiar with Copper Spray. My experience using engine oil is that it eventually dries out and coagulates, causing the gaskets to bond to the surfaces and tear upon removal. I've never had H-D grease do that.

Permatex copper spray a gasket that can be found at most parts stores. It's good for high temp apps where there may be leaking gasket. The copper coating helps it seal if you allow it to cure properly.

Thanks lmh! Never thought to use it on paper gaskets. I'll have to try that out as well.

I have never used ANY sort of sealer/oil on any gasket on a Japanese engine. Any gasket I have installed and had to take apart later came off easily, usually with no damage. I think since you may have been the first one to remove those gaskets after 25 years, they were hard and stuck to the surface, which is normal.

My preference has always been dry. You are welcome to try anything you like.
