Title: small orifice?
Post by: eddie on 24 September 2008, 03:41:13
In the process of sorting out a missfire I decided to clean the crankcase breathers.  Found the larger pipe to be relatively clear,but the small (orifice?) about 2 mil across was blocked solid.
I have cleaned it out using a small drill bit.

Just wondering what the hell such a tiny hole was used for and what Plank put such a tiny hole in such a vulnerable place? What are the expected consequences of that hole being blocked?

On the breather box at back of drivers side head?  If so, should just have a pinhole in it :)

It needs to be a pin hole to restrict the flow into the inlet at idle  :y

Same here had to drill mine out, amazing how much the hoses were blocked up too
