Guys with 90 mm FAST & MTI/TPIS TBs
Guys with 90 mm FAST & MTI/TPIS TBs What are you guys doing with the PCV system, as these TB don't have a provision to connect the passenger side valve cover? I tried putting a breather filter on, but when I hit the upper RPMs my valve cover gaskets blew. I just finished cleaning up 1.5 quarts of oil from my engine bay.

the air flowing thru the bellows would draw in some of the gas (just like the OEM TB).

Good post, I had not realized this was an issue. Has anyone actually SEEN the Fast 90mm yet and are sure it doesn't have the provision?
The only problem I see with tapping the bellows would be you get crap all over the TB blade when it's closed and inside the bellows and TB... ETC. I wouldn't recommend doing it if you've ever seen the back of a TB blade on a car with more then 10k miles and it hasn't been cleaned you'll understand.
what I would suggest doing is seeing if you can modify the place where EGR should be and then putting an NPT fitting in there.
Of course if you have EGR and want to use it then you have another issue.
