| I am using a Stewart-Warner borden type gauge connected to the top of the oil filter adapter. I checked it with my air compressor. I dialed in 100 psi in 10 psi increments and the gauge read exactly the same as on the air compressor. I changed all the press-in plugs to threaded ones, put restictors in the heads, plugged the lifter galleries (am using solid lifters), enlarged the oil gallery from the pump to the adapter, flared the adapter mounting boss on the block, chamfered the main bearing holes to match the bearings, etc. Clearances are 0.002" and no bearing wear is evident. I have tried different types of oil filters with no change. I use 20W50, but the same probalem was there with 10W30 which I used for break-in. It's just strange that the oil pressure rises so slowly as well as pressure not quite making it to where it should be. The only thing I did different from my last engine was to use the drain-back sheet metal trays which may not seal well with FPP support stands. But even so, I have restrictors in the heads. I even inspected the cam bearings which the machine shop installed and couldn't see anything wrong there. So.....that's why I call it engine #13...for bad luck. |
