Re: 0 Compression in Cylinders 1+4
If it did it all of a sudden and has zero compression, I would say a stuck valve. Could be bent could have a sludge of crap in there, maybe some carbon chunks....?
Rings.....would not just go out all of a sudden. Youd probably have low compression, but not none.
If your dipstick is not coming un-seated or blowing out when you crank it, I think its safe to say you havn't any holes in your piston.
I bet its something with the upper components. Valves, valve springs, cam lobes, cam, etc
If the valves dont close, there will be no compression. Do a wet compression check. This should make a quick seal around the valve, allowing a compression reading.
