But the last couple of days there has been smoke coming from the exhuast. yes i know smoke will come out from the car sitting for a bit and thats wht an exhaust dose. the thing thats is bothering me about it tho is it smells like fuel and kinda gives u a headach. i have thought possible head gasget but it dosent get any thinker wen you are driving its only at a idle it dose it. when you take off it give off a cloud like it was burning oil.. what the hell is going on.. and nother thing i have a fuel pressure gauge and today i was watchin it as i pushed the throttle and it was around 35-38psi but drops wen u hit the gas and it was like it just keept ging down is this normal? dose it have n e thing to day with the other problem or what? thanks for help

attention to detail when modding will help future pitfalls as such,, check for any vaccum leaks and set timing properly

it's possible you didn't get the intke gaskets seated properly and it is pulling in oil from the bottom side of the gaskets

It's basically standard measure that you do NOT use the cork gaskets on the front and back of the intake. Only use the gaskets between the intake and the cylinder heads. Use a heavy bead of silicone where the cork gaskets should be(front and back of block to lower intake mating surface).
