Did you check for a scored or damaged crank? I've seen it several times with amateur installs that wreck the front of the crank and it never seals right.

Most shops remove the blower to do an upper, so maybe something got screwed up there. It sure sounds like the crankcase is getting pressurized somehow. |

Different car obviously but I had a ‘12 CTS-V (wagon!) that went through two SC belt idler pulleys and on the second failure the belt wrapped around the crank snout and murdered the front main seal. Do these cars like to throw belts or have idler failures once you go to smaller SC pulleys (or larger crank pulleys)?

I was honestly on the cusp of scheduling my car for the 750hp package. Going to vengeance tomorrow to get scheduled. Anybody got anything bad to say about vengeance?

Not me. One of the best things about Vengeance is that they back up their work if there ever is a concern. Extremely customer service centered.

Exactly why I have decided to pay a bit more and have vengeance do the work. Haven't heard anything bad about them.
