Message I yanked out my blow off valves over the weekend as an attempt to figure out why they weren't functioning. I read on here that there is a common issue with corrosion, road grime, etc., clogging up the valve and causing them to stick. I figure I'll give them a cleaning and see if that works out. Pull out the driver side bov and it doesn't look too bad, however, the passenger bov is caked in oil. Also, in the piping you can see a little puddle, maybe a few mL, of oil.

After seeing this, I immediately ordered the PCV replacement kit from Courtesy (hoses and valves). Just the other day I noticed my dipstick blown out and I've had a small oil drip. Obviously the PCVs were in need of replacement.

In any case, I cleaned up both BOVs and still nothing. No pressure release when shifting, etc. I haven't checked for other causes yet. Can you guys point me in the right direction as to other possible causes that I should look out for? Any particular hoses, connections, or common trouble areas that I should check out?

The BOVs are mounted into beneath the air intake into the stock recirc valves (I'm assuming, sorry still a noob).

Thanks always and everyone's help is much appreciated.
