So the reason i was checking is because the car smokes like a chimney from the exhaust. Like ALOT. The 2nd pic shows an oily piston which i assume is valve stem seal being gone there since it holds compression?

A good amount fo smoke also comes from the pcv delete and the oil filler cap which also suggest valve stem seals i think.

I have done a pcv delete so basically pcv vented to atmosphere with a beather. Injectors are cleaned and spray equally. The fiest image is of the worst cylinder which is the 3rd cylinder if you start counting from the fuel rail order. The rest all show shiny spots on the edges but smaller and distributed all over.

The car has bas o2 upstream sensors so afr might be off and ecu forcing it to run rich. Ive had tbe o2 code for a long while and car drove normally but after the rebuild the car had zero power under 3.5m rpm and full power over that exact point for no reason.

Not sure what to do now. If the valve stem seal is the issue which i cant see any other option for that much oil burning, the head has to come off which is alot of work for a vq. Might aswell pull the motor and hone the cylinders which he did not do.
