Question 7.3L PCV Re-Locate Questions.......

Hello ,

I orignally posted this in the 7.3L forum but had no luck , maybe someone here can help me out....

I did a PCV re-locate this weekend and I have a few questions for someone who knows alittle more about diesel motors than I do ..

The stock system purges the crankcase pressure into the intake tube , right before the turbo. From what I have read , this causes excessive amounts of oil to build up over time in the intercooler , and thus making the intercooler not work as well. What I did was run a hose from the stock PCV breahter adapter on the valve cover to a racing cach can with a breather on it. All in all no issues except it looks like I have a fire under my truck due to the steam comming out of the breather.

My new idea was , to weld a bung in the exhaust and run the PCV to this , so the exhaust would actually help suck the pressure/steam out of the crankcase , as well as no more "smoke" under the truck. Racecars use this type of system, know as a Crankcase Evac system , and as far as I can see , would work on the truck as well.

Anyone have any feedback on this ??????

I wonder if the volume of exhaust, especially under boost, would actually suck oil out of the engine.

Not that I've heard about, supposedly installing it in the exhaust creates a better ring seal, and improves efficiency a little bit. Currently mine just vents to atmosphere out behing the back doors, but I plan on switching it to the exhaust whenever I get the initiative to go weld this bung in.

Thanks for the replies. I just wanted to hear from some other Diesel owners before I went and did this mod.
