could be worn piston rings have you checked the spark plugs are seated correctly? Have you done a wet test?

Broken pistons at a guess , ringland failure.

Head off, sump off, pistons out.  :sick:

Heads don't lift on these engines unless running silly boost from a hybrid turbo, or massive detonation.

As you haven't mentioned the spec of the engine at all, I'm going to hazard a guess it's had a Stage 2+ remap, with pops and bangs (natch), and it's either burnt out the exhaust valves, or smashed the ring lands as GVK said.

If the latter, you got off lightly, throw a new head on it and go about your business.

If the former, chuck the motor in the bin and get a new one.
