electric air pump?
hey guys I'm new to this site but have been around the cumins motors in heavy and light duty applications for a long time. I have been wondering about something for a while now. Had a thought to put an electric smog pump off of a late 90s early 00s gm car or truck on my 96 cummins to reduce crankcase pressure. What do you think? Good idea or bad? I know the trucks have a blow by tube to relieve the pressure but what if I did the pump to suck the crancase down to negative pressue. Wouldn't be enough to hurt anything just a few psi maybe 5-7 max. And it would prolly help with oil leaks to. I run one on my elcomino drag race car and it works great if it doesn't turn on I loose a tenth of a second just by it not working. So give me your thoughts any input is appreciated.

The turbo drains into the oil pan just under regular gravity. There is an orifice usually in the turbo on the pressure side of the oil line to help control flow. If you create a vaccuum in the oil pan though, it will try to pull this oil through the turbo as well.
Also on a reliability side, you'll have to seal the engine up to be able to create this vaccuum, what happens if the pump burns out or blows a fuse going down the road.
I think the "keep it simple" rules apply... atleast if it's your daily driver.
