Valve guide moved

[Phillybo]

if the head has not been off, do a visual inspection with a bore scope on the piston. You may find that the pushrod was bent when the piston and the valve met. That can be because the piston cracked and broke into a top and bottom, or a valve hung open. The leak can be either the hole in the piston, cracked piston or a broken guide and bent valve where air is leaking past the guide. Usually that will also show up in the intake or the exhaust.

I don’t have a scope.It did sound like some air movement around the valves also But mostly out of the dipstick. The plugs got slightly oil running it just for a couple minutes so I’m guess rings or piston.
