I have a 346 w/6.0 heads and cam with a vortech blower on it. When I get on it it presures up the crank case enough to push the dipstick out of its hole and blowes oil under the hood and on the headers. I am not sure what else I can do to relieve the presure. It has a hose that runs from the PVC system to the intake of the supercharger but it must not pull enough of a vacum to keep the presure down. Does anyone have any ideas to offer. If you do please let me know I have a few of my own but I wanted to ask and see what other people have had to do. Pictures are helpful on this subject as everyone seems to word the descriptions of the parts a little different. But what every you have to offer would be appreciated. Thanks in advance!!!!!!

I'd do leakdown test (or have it done at a garage) to check for piston/ring damage. If you're pressurizing the crankcase, that's a common cause and there's no band-aid fix for it.

Yeah I don't think that is the case here it only has a few miles on it since the install of every thing and it only happens when you get on it in the upper RPM ranges but not ruling it out the car only has 13k total on it.

Let us know how the leakdown test goes. Any cylinders below 90% and you have issues.

Both PCV lines...the one that goes to the intake and the one that goes to the TB need to be away from boost. They need to be upstream of the supercharger. Either line is capable of pressurizing the crankcase.

I'll look but I think they both are for sure I know one is so I will take a look thanks for the suggestion.
