Well I just got through with installing my new alky control kit, tested out the system which worked just fine. Took the car out for some more tests. I started out with 17 psi without akly running fresh 93 octane and I would see barley any knock retard on my scanmaster. I made incremental increases in boost, and when I got to the 20 psi level the car would pull great through 4th gear with 0 knock. Alky was spraying, and then after making one last adjustment to bring the boost to 21-22 psi, I heard the pop, oil blew out the passenger side breather, and I could hear a very noticable hissing sound right under the intake on the passenger side. Blue smoke would come out exhaust when under throttle.
I then shut the car down, checked oil to see if any water got in, but it looked clean. Same with coolant. I managed to get the car home and I then noticed that I also blew a small hole in my exhaust right before the muffler.
So my question is why did this fail. Everything was running great, the car pulled hard, alky was spraying (set at 6 as mentioned in instructions) and again didnt see any knock whatsoever. The motor has 110k on it, and has never had the heads on intake pulled before so I know the gaskets are original. So is it just a matter of its old, and they lasted long enough or what?
