sounds like upstairs and downstairs are having a problem. Def sounds like timing and/or valves are not right. Also sounds like the lower end is also making noise. Very hard to tell from video but that definately has a problem. It does sound like top end and lower end are having a problem. Compression check is good you say and thats a good sign but neither a compression check or a leak down test will tell you if you have bad oil rings. They are under your compression rings and it may be holding compression....but the oil rings could be shot causing oil to get into your cylinder...foul spark plugs. Basically a slow death....but still fatal....( I consider anything where you have to split the cases to fix as fatal...Anything is fixable but when it gets to that point it is very costly and time consuming!
