Ok.. I am need of some serious help.. I currently bought a 1989 Ram 50 with the 2.6 G54B motor, 5 speed 4x4.. I took the old carb off and replaced it with a new head , 38/38 weber, flowmaster exhaust, and performance cam. The truck ran great with the new head except for the fact that oil pumped out of the breather on the back of the valve cover.. The PCV valve works and is also brand new along with the oxygen sensor.. I took the cam out and put a stock cam in the truck but the tail shaft on the cam was too long and stuck out the back ( probably a cam for a front wheel drive 2.6) so to make it fit inside the head so I could use my cam plug, I had it cut down to the size that fits in the truck version and the motor runs rough.. The whole entire truck shakes at idle really horrible when cold but no so bad when it is warm. When I drive down the road, the truck runs perfect.. What is wrong ? If anything, I would like to know how I fix the oil from coming out of the back so I can run my bigger cam.. anything would help.. Thanks
