Thank you. Garage have told me today, it might not be as bad as first anticipated, might not be complete replacement of head gasket
Ronnie, a partial head gasket replacement is a new one on me for a car. Can't say in 30 years of engineering I have come across a partial head gasket! Many large engines have a separtate head for every cylinder but as a general rule car engines have one head, maybe they mean another gasket when the oil system connects to the head.
Usually there is a ferrule (small pipe) on the mating face between the block and the head, which is the passage for pressurised oil to pass to the top part of the engine. This is generally at the same end on the block as the oil pump. The seal for this ferrule is usually made by the head gasket, although larger engines may have a separate seal or an external pipe fitted. Once the oil has done its work it will drain back into the sump under garvity via passages in the block.
