Let me remind you that my motor has 108K on the clock and leaks a bit of oil from i dont even know where.. Whenever i would go WOT, i would smell burning oil, but i just thought the smell was out my exhaust.. Last week i noticed my lower intake right inback of the waterpump was a bit wet, but i thought not much of it.. Today my blower just got shipped back from vortech and i put it all on and ready. As soon as i got into boost for a few times, i smelt that oil burn, but MUCH worse... I just thought maybe the oil return line was leaking. Come to find out, i popped my hood and the front of my lower intake in back of the waterpump has PUDDLES of oil! and in the back it is dripping down on my oil pan and then to the ground badly..

What do you guys think the culprit is here? would a lower gasket have anything to do with oil? or is my problem elsewhere...

Thanks alot

well for sure you have bad lower intake gaskets. I'd recommend getting the rubber ones and not using the cork ones. I'm not sure of the part number, sorry, but use the fel pro rubber ones and a little bit of RTV, but not a lot.

When you use a s/c, the pressure has to go somewhere, that's why you run the hose from your valve cover to the airbox/atmosphere and cap off the throttle body connection.

Hey, by the way, when you do your lower intake install, go to the hardware store and get yourself 4 bolts the same size as the lower intake bolts, chop the heads off, slit the ends and use them as dowels...helps so much lining up the intake and you don't have to mess around and screw the gaskets up. then put a couple bolts in (not torqued down!) to hold the intake in place and pull the dowels out w/ a screwdriver (or vice grips). You can also use them to line up the upper intake. :nice: Michael Yount passed this advice on to me and it helps a ton :hail2:

Sounds like you might have boost finding it's way to the crankcase -- and that crankcase pressure is forcing oil out the path, or paths in your case, of least resistance. Changing the gaskets won't do much until/unless you find out how you're boosting the crankcase and eliminate that.

This is a great example of why the base operating/running condition of a motor should be sound before asking it to do even more via boost. Sounds like you'd do yourself a favor by freshening up things with a big gasket replacement party before you crank the boost to the beast. If not, you'll likely continue to chase leaks, or worse.

the tube that used to go to your valve cover to the TB. Is it still hooked up there? You should have plugged the TB side, and put a hose from the valve cover, to the inlet of the blower.

If you don't do this, you are pressureizing the crank case by blowing air into the PCV, and the TB to VC line, therefore blowing out your lower intake seals. If you continue to run it like this, you can even blow out your crankseals.

Another option is to remove the TB-VC line and plug the ends, then install a breather. But I don't recomend this as it only causes more problems. And remember you are presureizing the crank case if you have the TB-VC line hooked up, even at idle....

Sorry dumb question, but where on the inlet on the blower

Anywhere AFTER the filter and MAF meter, it CAN'T be in boost (such as in the discharge). I have a power pipe on mine, so I drilled a hole and put in a barbed fitting for the hose. If you have the Vortech airbox the instuctions for it should have told you to do this.

I think this is my problem too!!

I recently posted about my pcv blowing right out of the intake due to crancase pressure... I have my Valve cover hose running to the throttle body... I guess all my gaskets are ok and the pcv is the best way for the air to get out. Does anybody have a picture of how they ran the hose into the inlet tube of the blower? I have a afm powerpipe, where can i run this hose?

If you vent the tube from the valve cover to the atmosphere, it leaves a crap load of smoke.

If you figure it out please post...

I don't know how similar your setup, but this is how mine was w/ a powerdyne

I asked Rick at AFM the same question, here is what he told me " You have to vent your valve covers, one way is put breathers on each valve cover or run one breather and your PCV"
