Re: correct breather for 1098cc 10cc engine

Hi
Sorry it's taken so long to respond. The 10CC Engine should not have the Breather Pipe from the Rocker Cover. This system was only used on the 10CG, 9CG Engines of the earlier cars. The correct set up for the 10CC Engine would be a Valve unit fitted to the Inlet Manifold connected to a Oil Seperator Canister which is part of the front Tappet Chest Cover, connected by a Rubber Hose. There should be no connection to the Rocker Cover and the Cover should not have a Breather Pipe attachment fitted.
For some pictures please refer to Terry Horlers excellent Book 'Original Sprite & Midget' which details all the information required in great detail.
Hope this helps
Regards
