If the car has overheated to a dangerous point., than a tell-tale item will be that the small, plastic screen inside where you pour the oil into the motor will be melted. But that doesn't nessisarily mean that engine damage has occured in 100% of all cases. My car has had this happen, and the engine still runs strong. Although generally I would consider myself to be VERY fortunate! Other than that, the motor oil is supposed to have the appearance of a "chocolate milk shake". It will usually be accompanied by foam. There may also be oil in the coolant as well in the case of a blown head gasket. Others on the list here may know of other signs as well. -Robert vin 6585 "X" --- In dmcnews@xxxx, "paulkane45" <paulkane45@xxxx> wrote: > I'm looking at a Delorean here in MN and I have a suspicion that it > has a blown head gasket.
