Pushing oil out the PTO seal


Working on 2011 Apex XTX I bought off season. MPI stage 1,shimmed , BOV @10 lbs. Has power commander and voltage clamp. We cannot get this thing to run well at all. AFR's are kinda all over the place. Wide open throttle is good 11.2 . But light cruise , mid throttle is a mess. I've got Scott from Modfather helping me with the tune and it's fighting us big time . It does not push oil or coolant and the leak down was good. Today things got worse ! After a few short WOT pulls it started pushing oil out the PTO seal . Has anyone ever seen happen before. Scott said he has never seen one fail before. Not looking good.....

Thats strange on the PTO seal, try unplugging the pressure sensor on the top of the throttle bodies. It will throw a code but see if it runs better on low to mid.
