no a thin film of grease can be applied but do whatever the gasket mfg. says. Depends on the gasket and engine manufacturer. Follow what it says in the service information.
A new head gasket.
IMO, this is only a temporary emergency fix. It will not permanently fix the problem. You will need a new head gasket.
No, nothing will fix a blown head gasket except replacing it. Sealer are only used in an emergency situation as a temporary fix.
Replacing a head gasket on a 1996 Honda Accord requires removal of the cylinder head, timing belt, and several other components. The head will need to be resurfaced. Remove the old gasket and place the new one with gasket sealer. Reinstalled the head.
Not likely.... I'd never use anything "temporary" on a head gasket.
NO you do not. That is what the o-ring is for. If you use sealer it will wind up in the oil and that is Not good.
it doesn't matter. it mostly depends on how it lays on the head. be sure to use lots of sylcone to prevent leaking. New answer; IF you use silacone on a head gasket, you will have a hell of a mess. NEVER put sealer on a head gasket. They do not need it.
There is none. You cannot fix a blown head gasket with any head gasket sealer of any brand. They should only be used in an emergency situation in order to get the vehicle to a repair shop. The only permanent fix is to replace the head gasket.
All the head bolts need sealer.
No, far too much pressure and heat is built up in the cylinders. If a head gasket has failed it often means that the head has become warped perhaps from overheating.
It is most likely a blown head gasket or a cracked head. Chemical sealers generally do not work. Your best bet is to replace the head gasket and inspect the head for damage.
Depending on the motor you may need to put a small dot of silicone at the corners where the intake meets the head of a V motor. 4-6 cylindar straight motors don't use sealer.
