i have 347 with a novi 2000 and i keep blowin oil out the valve covers under wot.. i changed my gaskets thinking that would fix it but it blows right through them.. i dont have vents on my valve covers.. should i buy valve covers with breathers on them or is there any other suggestions? thanks for any help

i have the same problem...you need vents because the crank case pressure is either goin to come out there or your oil pan gasket...i didnt have room for breathers because of my throttle cable bracket on the passenger side and the intake manifold on the drivers side so what i did is got a rubber groumet and poked a hole in it pulled a piece of 1/2 hose in it and on the other side put one of those breathers on it (just one of the apc import ones that come with a clamp) and clamped it on the other end and wire tied it to a wiring harness nearby ..it looks clean and its effective...no more oil on the valve covers....BUT if you have room i would put breathers strait on the valve covers

You don't have a breather on either valve cover? It helps to have at least one breather and two would be ideal on a boosted car. I have a single breather and the oil was leaking through my older over torqued rubber gaskets, not as much on the side with the breather but that could have been unrelated to having a breather. I replaced them with Mr Gasket MRG-5870 from Summit and they have been holding so far. There are valve cover gaskets that claim to be much better but these have worked for me so far. If you already have a decent gasket, I'd say the lack of a breather is your problem. That pressure has to go somewhere, might as well let it go out a breather and not somewhere you don't want it to go.
