head gasket

I have been doing some work to my 1994 mx-3. New water pump, new belts, timing belt, fuel filter, air filter, basically everything is replaced or is waiting to be replaced.

Now I'm at the point where I'm waiting for my new head bolts to come in from mazda as well my new valve cover gasket.

The online workshop manul is confusing to understand where it talks about the head gasket. All I need to know is do I apply any sort of gasket sealer on the block, and head, before I join them? If so what kind, and how much. Dont work I very carfuly sanded off all the old gasket left overs. Also it says to torque between 50-60 lbs I was thinking about around 58lbs . What do you think?

thanks.

It should say, don't worry I sanded off all the old gasket material.

I wouldn't use any gasket sealer. Maybe a copper sealant... the spray on type...

ok, so no sealent of any type. Thats what I thought, but I know some people do it differently. Any other info from you who have done a head gasket on a rs might beable to recomend before I start it up?

btw- incrediable pink works awsome on the inside of the intake manifold when cleaning it out. Very nice degreaser. works great.

I hope you have the torque sequence for the head. If not I can get it from work tomorrow for you.

Also when you torque the head down first torque it half of what the final torque is... so maybe torque IN sequence to 25ft/lbs, and then IN sequence to 58ft/lbs or whatever you choose.

I do believe it's an MLS (multi layered steel) gasket, and you don't have to use any sealer.

BUT on the valve cover gaskets, there are places where you should dab some silicon sparingly in the corners to help it seal. On either side of the end cam caps, and the distributor cap at the rear.
