OK, I have a 360 in a CJ and have always been holding around 30psi at idle hot and thats after installing a oil pump kit and new oil pickup tube about 500mi ago. The engine has around 2,000 mi on rebuild. After playing around the other day my engine started knocking and I realized I had 0 PSI. I need to replace the main and Cam bearings now. I tried repriming my current set up and it pumped back up to 15psi so I got pressure back. The pressure is low now due to the main bearings wore down to the copper. Anyway I have been reading alot on here about oiling and now I am lost. Would it be better to buy a stock oil pump cover and a mid plate seperate, or just buy the nickle plated oil pump cover and skip the mid plate. Either way it works out about the same price. I will buy your hand lapped gears to go with this. My tolerance on my gears to timing cover is .004.
