So I had this idea...since I have an abundance of chemicals...

I thought...what would happen if I used some kind of high tack, Indian head, gasket sealant on the block and heads when i do the head gasket job?

Has anyone coated the block surface or head surface with any kind of sealant or glue to make the gaskets stick better?

What are the pros and cons?

The stuff i have is resistant to any normal engine chemical, coolant, oil, fuel, and with stands temps of 400 degrees.

Can I get your opinions before I start on the job?

 

400 degrees is about 1/5th or less of the combustion chamber temps. Also, having something tacky would probably cause the gasket to tear under the normal movement of the head and cylinder block.

The gasket not sticking isn't the issue with this engine, it's how close the water jackets are to the bore, as well as the bore spacing itself

 

Which problem are you attempting to solve?

 

 

Doing it again.

I used indian head shellac on an oil pan and front cover once. Removing the pan destroyed the cover and pan.

I thought, coating the parts and then slapping together., let it dry, and it might be stuck for good.

I did the head gaskets about 100,000 miles ago. This time the rear driver side is spewing cooalnt.

The combustion chamber temps arent an issue for most of the head gasket.

 

Most head gaskets are silicon+metal.

Cometic head gaskets are all-metal. I'm thinking that the Cometic approach is how you avoid doing the head gasket job again!

 

If you really feel compelled to apply something special to your head gaskets, what's wrong with the tried and true copper coat? It won't glue everything together and seems to be pretty effective at maintaining sealing effectiveness in the long term.

 

 

 

Yes, but the Cometic gaskets that I bought covered half of the oil dipstick tube hole so they may require some cutting. I did.
