RossD 44 Posted November 1, 2008 If I were to shove a small filter on the top of the breather outlet on the top of the rocker cover, would it fail the MOT? The car has TB's and so it's not as if I can plumb the breather back into the induction system!! Cheers Ross Share this post Link to post Share on other sites

base-1 17 Posted November 1, 2008 The likelihood of you failing for it/the tester noticing/the tester giving a crap is probably miniscule, but strictly speaking it is an exhaust gas and has to go through the exhaust system. Just leave it tbh Share this post Link to post Share on other sites
RossD 44 Posted November 1, 2008 Cheers chaps, I'll put one on and hope for the best then! Share this post Link to post Share on other sites
boldy205 75 Posted November 2, 2008 you could just put a pipe on the cover and run it down the back of the engine, the MOT person wont even notice then, thats what i did with mine. Share this post Link to post Share on other sites
RossD 44 Posted November 3, 2008 I was thinking of doing that too, but none of the local factors had an pipe of the right diameter! Share this post Link to post Share on other sites
arnold naber 2 Posted November 3, 2008 you could just put a pipe on the cover and run it down the back of the engine, the MOT person wont even notice then, thats what i did with mine. That does the trick in the netherlands... i use a oi catch tank i take of the little filter nput a hose on it and it vanishes between the rest of the pipes Share this post Link to post Share on other sites
