Black oil quick

[cretin]

Stock intake? I came across a situation recently where an aftermarket intake didn't have an exhaust crossover, but also nothing to block it off, so if you didn't block the ports in the block, it would put exhaust in the valley, which would make the oil black, among other issues.

Cretin, I believe the block ports are plugged, stock aluminum intake. I need to check my build pix.

If they are blocked, it could cause dirty oil?
