Next order of business.. is the use of sealant necessary on the Thermostat housing base to cylinder head gasket? If so which is recommended? Blue RTV?

By the looks of things the was sealant used on the old gasket, but not sure if it was the same as the new felt gasket I have now.


Cheers guys,
Callum

Use the gasket if you have one. Ultra blue will be fine if not.

Just scrape the old s**t off first.

And do it when you fit the inlet manifold - the lifting plate uses the top bolt of the thermostat housing along with the upper bolt of no1 inlet runner.

+1!

Put a smear of rtv blue on both sides of the new thermostat housing gasket anyway, i always have and never had a drama. Better be safe than find out you have a leak there in 20 mins..

I've mostly used blue (and twice the black toyota sealant) the gaskets don't last long on m ine because I'm often pulling the housing on and off doing the intake manifold or whatever at the time..

Check the flatness of the face with a ruler, they do warp. You can put some emery paper down on a flat surface and run the housing on it in a figure of 8 motion.

Yeah, check for corrosion and pitting as well that may thin the edges in some spots.
