I have had a persistent oil leak from the rear main seal.i replaced it some time ago and it held for 15 min.then started running out really badly.someone told me high oil pressure might cause this leak so i put a pressure gauge on it and it only came up to 6 psi cold.i thought the gauge must be wrong so checked it out and it was right on.this 312 only has 15.000 miles on it.i pulled the pan and checked bearing clearance,because i figured they must have excessive clearance,but they checked out ok using a plastigage .002.i had a oil analysis run ond nothing unusual showed up.so i guess my question is other than a bad oil pump is there anything else i should be checking.i did pull the engine out .oh yea i guess i better say why the rear main seal leaked.i read everything Ted wrote about rear main leaks and followed his advice to a t,all the proper cleaning and proper use of sealer.but i did one of most stupid things possible,I PUT THE BOTTOM HALF OF THE SEAL IN BACKWARDS. talk about a senior moment.any advice on my oil pressure will be greatly appreciated.the pump i have in ther now is a rotary   Carl   Ohio
