110 vented case

[parkerwarn]

Has anyone ever drilled and tapped a 90 degree brass fitting right below where the oil dipstick is and ran a hose off of it to remove some crankcase pressure? My 110 is building quite a bit of pressure in it due to being 56mm, full race cam, ported head, and ported intake manifold.

I drilled out the centre of a dipstick slightly offset of the stick portion, threaded in a brake bleed screw and ran a clear hose way up into the frame. Poor mans venting but it worked.

I second the valve cap vent on the top. we used to run the Chinese clone motors of the 110 engines for my son's racing. drill a hole and run a 3.8" 90* barb off the top valve cap and your set. just connect a hose and plum to a T that goes from the crank case and your done.
