Alright while messing around with my car today, I noticed oil in the Throttle body. I have a 90 GTU, so I have no clue how oil could get into the TB. I am thinking maybe somehow the Purge control valve is malfunction? Any ideas?

Anybody have any ideas?

I know how the turbo FC's run it's purge valve back into the TID fitting, but the NA's should have a similar set-up.&nbsp Yep, you pretty much hit it on the nose...

Any chance you got a little to excited the last time you oiled your K&N?

Hehe...actually, yes. I didn't even think of that. But still I'm pretty sure this is castrol GTX oil, it smells different than the K&N oil.

so as I understand the PCV, it uses vaccuum off the throttle body to pull vapors from the oil crankcase or whatever, and recirculates them into the intake stream to get rid of them. So how could oil get sucked up into into the TB, unless the oil level was too high or something, or WAY to much vaccum was being applied to the PCV or something? How could I go about troubleshooting this? This is probably why my car is using oil, and blowing blue smoke on startup.
