I am trying to track down oil in my intake issue. I have changed the check valve and tested the pump, which works as it should. Even though everything is working after about 300 miles I have oil all throughout my intake piping.

I was thinking of jumping my pump so it will run on HIGH SPEED all the time. Will this hurt the pump?? I just want to see if this fixes the problem.

I also read where someone put a nitrous jet in the oil feed line to lower the pressure, is this a common fix?

 

I think we all get a little oil now and then.

I would try jumping the switch to put the pump in high speed. It shouldn't hurt the pump. Not sure if it will take too much away from the turbo, but sts now ships their kits to the northern areas with a switch that goes in the cab to do just that for the colder weather.

I would not try starving the turbo of oil.
