I have a problem with a 1985 Fuego. It is running very roughly and there is a line of oil spray that has appeared on the exhaust manifold. There is no oil pipes on that side of the engine and so I assumed that it was being blown out between the head and the block. I compression tested the car when it was cold and found that all the cylinders were around the same pressure(163-172 psi) so now I have my doubts as to it being the head gasket. The car is also backfiring and totally gutless at the lower speeds but improves as the engine revs increase. There is no perceptible sign of water in the exhaust and no obvious loss of water in the system. Any suggestions as I am desperate!
