Hello. I have a problem that has got me stumped once again on my 235.
When i start the engine completely cold, I get about 30-35 pounds of pressure. Rockers are oiling great.
Now as the engine warms up and runs for awhile at idle, I start to loose pressure. It eventually drops to about 10 pounds but im still getting oil to the rockers but not as much. Here is some info that im using.
58 block
54 head
Brand new oil pump
external oil filter mounted on intake.
Running 10-30 oil.
Any ideas or help would be great.
