B16 Low power real problem

Ok let me try to explain. Was doing about 6k rpm's and heard a LOUD POP.

The engine still runs with no knocking. However very low power. (No smoke in the exhaust)

There is Blow By from the vacuum hose and its not Oil, it feels like Steam.

Oil in crankcase is not milky, water in radiator seems to hold its level.

I have not been able to compression test it yet. Still also looking for a Borescope.

So any ideas of how bad it is? Not sure if a cracked piston, or hole cause would be right because would see smoke from exhaust.

Maybe a bent valve?

Please help brainstorm.

if it was a bent valve youd know it... it would run like shit... maybe timing jumped a tooth??

Yeah I am trying to firgure out the easiest way to deterime if timing jumped, any ideas?

pull your spark plugs, manually turn the crank puly counterclockwise until the engine is at TDC. remove the timing belt covers and make sure the mark on the cam gears is lined up

why were you redlining your car in the first place ok when its idling and you press the gas does it stumble or hesitate or what does it do when you press the gas
