1987 1.3 Ford escort ohv 34,000 miles , it starts fine , it drives fine , but when you accelerate hard in any gear it kangaroos a bit - jerking forward .... When its in neutral when you rev it hard the engine knocks and vibrates like hell - the gear lever vibrates like crazy as well .... The mounts are all fine ... I,m thinking its the camshaft???? But I,m guessing ??? Any pointers ... Please Roy
