oil leaks after blower install

[red 408]

around christmas i saw some posts regarding oil problems after installing a blower. can sombody help me out with the part # for the buick gn check valve? does this help stop oil from getting into the intake upper? a friends car was having this happen with the factory motor and 10 psi. haven't opened it up since new stroker mtr, but it sounds like good insurance. i also have been wondering about the effect of the stock breather line from the oil fill neck to the t-body. left in place wouldn't this also allow boost pressure to escape/pressurize crank case? if i remember correctly his saleen had a cheap auto parts store glass case/ screen fuel filter in this line. on my previous blower installs i deleated this line and went with a breather replacement oil cap. any ideas out there?
thanks

Get rid of the line from the valve cover to the t/b......then put a filter were your oil cap was this will help vent crank case pressure. Also check that cheap ass oil drain back line from the blower. If it is the on that came in the kit it will only last about a year before it leaks. Use a -10 line for your oil return line.:D

thanks bk, already dealt with the oil leak thing, he almost bar-b-qued an SA-10 in his driveway:eek: removing the cap and line for a filter is what i've done before, but buddy wants to keep original saleen look (what ever, if it works better do it, but i don't own a saleen).
