i did a search and did find a lot of useful info on this product. the only thing i couldn't find was has anyone installed this breather tank (catch can) on the motor while it was in the car without removing the intake manifold? just wondering it was possible and how much trouble would it be to do it that way. thanks

 

As long as you can get under the car it should not be a problem at all.

 

I know whenever i installed my crankcase evac system i just took off the IM. (car was parked for winter anyways) (It only takes like 30 minutes tops)

But ii didnt have to crawl under the car anyways whenever i unbolted the stock vent box. You might be able to get away with doing it from underneath, but im gonna say its real easy when your lookin at it with the IM removed.
