So I am actually in the middle of doing body work but figured since I wasn't driving the thing I would continue my investigation into my oil burning. I have been soaking the cylinders (but not hopeful) and when doing that I ran my scope camera to see how full and noticed the exhaust valve open.

Seems like it has a ton of build up from what I can tell in the pic. I have replaced valve seals and lower intake gasket, new pvc etc.. Just curious if anyone has any suggestions on getting some of this cleaned up without removing the heads or lower intake? I feel like my oil control rings are bad but at this point going to drive it until I feel like spending the money on pulling the engine.

Any good ways to clean the back of the exhaust valves. This is the number 7 cylinder and that is the exhaust valve in the front and you can see the piston and valve relief. Looks to have a ton of build up.

Everything stock except exhaust.
