no compression in 86 oldsmobile engine Sign In

replaced head gasket and have no compression in the engine what so ever. the pistons are not ceased and the firing order is correct. everything is moving in time so i don think it is the timing chain. but i cant figure out why there is no compression

Ok - it's an Oldsmobile - any particular one?

Put a cylinder on TDC and use compressed air in plug hole and you'll see where the compression went. If this ran it strongly points to valve timing being way off (chain/belt) and probably an interferance engineUnsure
