Keys checked, still perfect.
Went through cycle 1,3,4,2 checking TDC and valve lash yesterday, all seems timed right...
Cam lash checked, all still good.
Cam lobes appear fine from what I can see and cam is not loose.
Put the leak-down tester on cylinder 1, lots of air coming out exhaust.
Put the leak-down tester on cylinder 2, air moving across cylinders it sounded like.
I feel like it's head gasket since all 4 cylinders went at the same time. Just going to pull the head and look at valves, etc
Main question: how the heck do you get the O2 sensor out??? Sucker is rusted(welded) in there!!!
