PCV Valve Re-route? (pics)

[oneslowwdsm]

So I have an aftermarket intake manifold on my 2g and it doesn't have a port for the pcv valve. So the previous owner decided to stick a rubber hose on the back end of the valve cover (where the PCV valve goes) and route it towards the bottom of the firewall open ended so it leaks down through there. I didn't like this (for obvious reasons) so I figured out a way to route it back into the intake.

Now I am noticing a good amount of oil in my intercooler pipes and there's probably a bit in the front mount as well. Is there anything wrong with this setup or am I just asking for trouble. I know the oil is not from any seals because the turbo is in amazing condition and I didn't notice the oil before I routed it this way.

Speaking of which, I would go this route:

While drilling and tapping will work, it's very easy to to strip the threads in a thin-walled IM, especially with tapered NPT threads. You are much better off welding in some bungs for a permanent solution.

Wow that's slick. I've gotta get a bung welded (on the exhaust) for wideband O2 logging and I might have to steal this idea and get them done at the same time!

You're gonna weld a wideband bung to the IM?

That should be interesting.

Hey... that was too good an opportunity to pass up.

FYI - If you have someone weld a bung on the IM, it has to be blasted and/or cleaned really well, and then "cooked" a few times to burn out the impurities that cast aluminum likes to soak up. The only way to get welds like those ^ on a 20 year-old cast IM is to be ABSOLUTELY SURE that all the oil and grime is removed and baked out of it, both inside and out.

Good advice. I didn't even think of that...
