dang, why didnt i think of that? Is there anyway around this? how about if I use one of those breathers attached to a catch tank.

Im thinking If I do end up using one of those breather/catch tank combos, I could put a 0psi check valve on the pipe that goes from the valve cover to the breather, which means when there's vaccum in the intake manifold, it could still pull vaccum in the crankcase, and only if the crankcase pressurizes will the check valve allow the breather to vent out excess pressure. Would this work?

something like this:

It allows unmetered air into the engine, in SD it doesn't matter since fueling is based only on map and rpm

 

Iridium plugs are very sensitive to the presence of oil. They will foul much faster than copper plugs in an engine that has any oil passing through the cylinders.

 

thanks, I could probably use some copper plugs, any suggestions on the gapping?

 

I would say stick close to stock gapping (.040) but since I don't know the exact dynamics of copper vs. iridium someone here may know how to better gap them.

 

That is where I'd start, looking at the plugs again. Carbon fouling from too much fuel can be any color, and oil fouling is not necessarily wet. Look up NGK's diagnostic photo chart, it is very informative.

 

also take a picture of the plugs with a quality camera and let all the experts on here look at them

 

10.7:1 CR and 8psi of boost, I think it should have a tighter gap, and should see 1.5-2 more psi when its done.

Still collecting a bunch of parts before I would start modding
