more than likely engine rings or valves. to find out either do a wet and dry compression test, or have a tech do one. this type of test will tell you which is the problem. the test is not difficult. you can check with the local parts store and they should be able to help. they will also try to sell you the tester. it is not an expensive testor. hope it helps. duboff
