looking at a LB7. guy says that the intake at the turbo leaked and allowed dust to come in and eat the rings and walls out. compression test shows right bank is 300-380 and left is 320-370. apparently theres alot of blow by out the oil filler.

how bad do you guys think the walls will be? any chance to just hone and run new rings? another consern is the turbo. if that much dust got in to destroy the rings and walls it must have done some damage to the turbine surface?

stock motor. S&B intake, exhaust, 30psi wastegate, DSP5(unknown how hot) built trans.

thanks for the input!
