On the weekend I decided to get to the bottom of my sticky throttle problem and removed the TB. Horrified to see that the back of the TB was covered in black tacky oil and golden oil varnish. The inside of the IM looked that way too.

I gave it all a clean with spray on TB cleaner and it came out nicely.




So I reconnected my catch can (it was disconnected because it leaked air) but this time to the breather side of the PCV system (pipe goes from VC to intake pipe.

And I added a second catch can too. For the PCV valve itself. It looks so messy but I had to ensure that the hoses ran downhill towards the catch can.



Catch cans are next to the battery. I used oil cooler hoses with ID of 8mm.

Has anyone else here ran dual catch cans?

I checked my compression thinking that I might have excessive blowby but all cylinders came out at 225PSI.

I think some of the mess may have been caused when my PCV valve stuck . . .

you could just not hook up the vent line back to the intake it is enviromental anyway. you wont throw a cel either.

Yeah the environmental bothers me. Prefer to not contribute too much more to greenhouse gasses if I can help it.

I should add that I found traces of oil in my intake where the vent hose is plumbed into it. That's why I added a catch can to the breather. Oil does go out that way at WOT when the PCV valve shuts, the blowby gasses take the lease restrictive route out of the crank case, which is out the breather.

its funny how most contries other than america have way less tighter emissions rules here in the us you have to have emisions aproved hoesing going from the valve cover to your intake. they are getting a little anal a, also oil catch cans are illeagal in california even though in theroy they make it run cleaner.
