I think it was you that said in an earlier thread that you planned on running it for 10K.. so at 1qt/2K miles all that oil will be gone.. what are you going to replace the lost oil with?
Good point... better go get another jug and make that a $160 oil change. But I suppose it's cheaper than pulling the rings on a 140k mile car.
What's in BG EPR?..is that a flush?
OP, have you tried soaking the cylinder?
You usually have to do more than one flush and/or soaks to achieve any meaningful cleaning effect, especially on what are likely very dirty rings. (140k miles)
