Compression Test Results

If compression is more than 15%-20% lower than the spec required by the factory spec you have a problem,weather minor or major.I would do a leak down test with the proper guage set and determine weather valve seats or rings are leaking on each cylinder.A wet test helps to determine ring problems and small amounts of valves not seating.The wet test should go up a noticable amount when cranked over.This is a ring problem,if only a small amount is gained,the valve seats and face are at fault.You can remove the plugs and put 4 oz of combustion cleaner in each cylinder and leave it over night to help disolve carboned rings that are sticking,weather be compression or oil rings.Mrmopartech
