Hello everyone, I'm looking for some advice regarding the current air intake set up on a 1956 Ford F100 truck. I have no history regarding details of the build on this truck, but it does have a 5.0 H.O. EFI engine which I believe is from around 1986. No idea on the history of the engine. When I first got the truck, I drained the existing oil and had it analyzed to see if there were any issues. The report was fairly positive except for some elevated iron and copper levels. As I had no idea...

Is my air filter set up contributing to dirt in engine oil?
