I got some high pressure in the system and its causing blowback. I am trying to eliminate all the small reasons for it before we open up the engine. Basically trying to avoid that, hoping its not a broken ring or something. So far we looked inside the cylinders with a bore scope, and didnt find any problems at all, the pistons were black, and no signs of lean condition. Cylinders 3,5,6 have low pressure in them, around 70-90psi, while the rest of cylinders are holding at 120psi. The pressure is forcing the oil out around spark plug gaskets, and if u get up to 9 psi and higher in the boost under load it completly blows the plug wire out of the hole. I can see where the little round gaskets are leacking. If you guys have anyideas on things that i can check without taking the engine appart i would really appreciate it.
