Oil Pump Issues
I have a Schiada V-drive with a carbureted turbocharged 540 cubic inch big block Chevy coupled to a Turbo 400 transmission. Recently, I noticed erratic oil pres-sure and now it is very low, especially at idle. The motor has a solid roller cam, so I don’t hear any lifter noise, and seems to run OK, but I am afraid to run it. The oil pressure gauge is mechanical, so I think the low pressure readings are accurate. Can you give me any ideas of what the problem might be?
