Re: oil pressure
Hey-Your motor pics up the oil through a pickup tube threaded into the block, from there it runs 5 inches to the edge pof the block to the timing cover. After it gets to the timing cover it gets pressurized and sent back out of the timing cover through the lower end and up the front of the motor to the cam bearings and up to the lifter, pushrods and squirting on your rockers. When you did the cam swap did you make sure the timing cover had a clean gasket surface?...On the passenger side of the motor(same as the pump...duh) were the oil reaches the pump cover there can be a slight air leak in which sounds like what has happened in your case...It has happened to me before too. Another thing...the timing cover might have warped after you took it off...when you disassembled the motor was it still warm to the touch at all?...if it was the different thicknesses of the aluminum could warp alittle...on the same note tightning it down could rectify(scary word) the problem. That what makes me think it is a unclean or a mystery particle of course that always seems to find itself in the worst place at the wrong time. I would just take a look at another new timing cover gasket and you should be able to figure what bolts to take out just to drop the timing cover/water pump out in one piece...DONT forget about the oil pan bolts and snap the cover.
