intake gaskets are not a prob at all. I've done a million chevy trucks with center bolt valve cover heads, they are prone to it. Diesel nut LOL, yes we are all sled pullers around here. I always figured it was the back valve cover hitting the exhaust since there are no oil spots, the underside of the car is clean , and you can smell it. Do you guys all think it could really lose a quart and a half out the valve cover in 3000 miles? you'd think if it was leakin that much that there would be smoke comin out from under the hood.
