A new head gasket.
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.
Because the head gasket is blown.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
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.
Sure it will start with a blown head gasket. But, if you continue to run this engine with a blown head gasket you will destroy the engine.
yea it works good on a boat motor In my experience the only permanent repair for a blown head gasket is to replace it. These gasket sealers are only a temporary fix used in an emergency.
Yes, I blown head gasket will definitely effect the emissions.
remove head and replace gasket :)
No. You can have the head gasket replaced. This is unless you kept driving the car with a blown head gasket and have totally destroyed the engine.
