Oil leak on S/C 5.7 after cam install - HELP Just installed a camshaft for a customer cam is a 224/228 114 lsa cam and the car is a 2004 5.7 GTO. The car already had a Procharger with intercooler and was fine. Upon fire up from the cam install I noticed a decent flowing oil leak coming from the front crank seal. I removed pulley and removed components. Reinstalled crank pulley and ran vehicle - NO LEAK. I reinstall the supercharger and bam immediately starts to leak at the seal. What do you guys think this could be. The PCV system is connected the way the customer had it. Any suggestions....

No I didn't. I bought one when I saw it leaking, but again it doesn't leak at all without the s/c spinning, no matter how much I rev and build oil pressure. I put the belt on and it pours out within 3 seconds of running at idle. Coincidence?

Did you use the alignment tool for the front cover? Without that & using an old seal I can imagine the blower might pressurize the case enough to make it leak.
Could be worse, I knicked my real seal installing it once & had to yank the tranny....
