The Tech Barn / Re: 327 oiling HELP
« on: December 28, 2009, 06:53:34 AM »
Just rebuilt a 94 350 in Oct, and had the same problem, check to see if the rear cam bearing is pressed in all the way, remove the plug on the back of the block to make sure, the bearing should have an oil groove in it, the hole does not have to be lined up thats what the groove is for. We tore that thing apart 3 times and put 3 different oil pumps in it before we found the problem, but make sure you pop out the plug, thats the best way to check. Do you have oil pressure when you 1st start it, then as temp comes up the pressure drops? If so thats more than likely your problem, as oil gets hot it acts like water, takes the path of least resistance and heads back to the pan, when we finally got it right we had 72lbs off the drill and 67 when installed and idling. Good luck and hope it helps.
