soldave Posted January 11, 2015 Report Share Posted January 11, 2015 Does anyone know off-hand what size the inside diameter of the breather hose is that goes from the crankcase to the airbox? Thinking about going without the airbox but would need a filter for that hose to go into. 18mm and 20mm spring to mind, but I can't remember which one it is.

markgenesis Posted February 14, 2015 Report Share Posted February 14, 2015 Ha, i just did this very job on my car yesterday Used a breather with 15mm ID adaptor and a short bit of 15mm OD metal pipe to join it to the hose from the crankcase. Breather is a cheapo one off E-bay, works fine. 1 Quote Link to comment Share on other sites More sharing options...
soldave Posted February 14, 2015 Author Report Share Posted February 14, 2015 Thanks for that. What did you do about the hose/pipe that usually goes from the rocker cover back to the airbox (the thin one)? Quote Link to comment Share on other sites More sharing options...
markgenesis Posted February 14, 2015 Report Share Posted February 14, 2015 My engine already had a breather on the upper cam cover (the top of it can just be seen in the bottom of the pic), so it now has two accessory breathers, one on the crank case and one on the cam cover. 1 Quote Link to comment Share on other sites More sharing options...
