Hi

I've not posted for a while but am back on my ME7 based autograss car hoping to get it done this winter.

Engine is a very tight fit and it looks like the breather box needs to be deleted to make way for a conventional throttle housing . I'm planning to remove all pipework and block off as required. Anyone routed the two hoses from the block to a separate can?

Thanks Nigel

Many have deleted the pcv in the past, me included and in many different ways, a common one is to tap into the rocker cover and take 1 or 2 breathers from there to a catch tank, if your removing the breather box then you will need to pipe up the hole on the side of the block into the drain hole below, I don't see why this wouldn't work, my box is still in place but this is what I planned to do on my next engine build. How's your grass car project going..? Any pic's of it..?
