We have answered this question many times at RAM and as often happens, there is no straight answer. Most of our gaskets do not require sealant. We would recommend gasket sealants alongside our solid gaskets only when necessary, if a flange is very uneven and it could help to fill any gaps and when leakage of the sealant would not be an issue.

But most modern gaskets do not need to be coated with any sealers. And if you're installing a coated gasket , avoid any chemical seals. Furthermore, can I use silicone as a gasket? That would be OK, you can also use instant gasket that is high temperature silicone at a push.

Even normal bathroom silicone sealant is temperature resistant to about degrees C. If the gap is too big between the pipe and slip-on can , try packing it with kitchen foil as well. You don't ever want to use a sealant like rtv on a cyl head gasket. So no way would you ever need to use a gasket and sealer at the same time. Just a thin material to seal the scratches is all that is necessary. Too much sealer and you could get a leak. Just use a gasket and you will be good to go. FelPro has said that if the engine has not started and the gasket is returned to the same cylinder bank and head you can reuse the gasket.

A general rule, if you are using gasket sealant , you don't need a lot! The UP stamp is found on Fel-Pro head gaskets for Subaru engines, which have horizontally opposed cylinders. The edge of the gasket with the Up stamp must be kept up toward the top of the engine block. I put a skim coat of RTV on them. I've never used sealant on paper gaskets.

With flat surfaces and proper torqueing you should have no need for it. Just a thin material to seal the scratches is all that is necessary. Too much sealer and you could get a leak. Just use a gasket and you will be good to go. Yes, some method of sealing is required if the engine will be running coolant or oil through the head gasket.

Since most engines run coolant and oil through the head gaskets we'll discuss head gasket sealants. Most importantly, you don't need very much; second, don't use silicone..

A general rule, if you are using gasket sealant , you don't need a lot! It is fine to use the correct RTV sealant instead of a gasket if used in the right application oil, high temp, fuel. Not, however, if the gasket thickness is required to produce a specific amount of clearance. RTV sealant is better than primitive gaskets in most applications ie.

Do paper gaskets need sealant? I put a skim coat of RTV on them. I've never used sealant on paper gaskets. With flat surfaces and proper torqueing you should have no need for it.
