hi there

I bought a full set of gaskets and oil seals for the entire engine, but I have some doubts about which of them are applyed in dry and others nead some kind of sealant or glue.

for instance: the thermostat housing in the engine head are a bit corroded, so I think it have to nead some kind of glue and others that I can't figure by the old gaskets if they had glue or not.

someone who had made this kind of total replacement of gaskets and seals could help me in a way to not make mistakes?

thank you

both thermostat and waterpump housing require a gasket sealent. (obviously one thats water resistant)

I use sealant on all gaskets except head and exhaust
Never use sealants with bearing seals
I have had issues with sealant and oil pickup so use a thin layer to bond gasket to sump and letting set.
Rocker gasket is sealed to rocker cover then thinest of layer on cleaned head surface
I often use O rings and sealant for the rocker cover bolts

Rule of thumb - card or paper gasket, use sealant (and normally just the slightest smear to cover it - don't drown it). For anything composite, don't.

Cork ones tend to depend on what its sealing, but I tend to use a smear of something as its usually something that has a tendency to leak!

Rubber gaskets (more modern sump and cam cover), then refer to manual (but normally a no).
Any exceptions I can't think of...?

cork ones improve with a smear of grease plus ut holds them in place while you line the two faces up

Cork or paper gaskets put Blue Hylomar on one sisde and a very thin smear of silicone grease on the other that way you can de-assemble the joint.
