I read / heard somewhere a suggestion that the valve cover can be connected to the carb to re-cycle the gasses. My car puts a fair amount of smoke from the valve cover holes, which enters the car.

Does anybody have experience of connecting the valve cover the the inlet / carb in some way? Any reason not to do it?

I have a Cambridge Ally cover and an SU carb.

Alternativly, is this just covering up the symptom that there is something else amiss that I should be addressing?

Thanks!

your valve stems and/or guides are worn. It'll use a bit of oil but other than that I shouldnt worry overly. Wait for the engine to die properly before you fix it. Knackered engines 'go' best!

My old engine did this so I filled up the holes and soldered on a elbow and took that under the car, aimed at the back axle. It is a soloution only to the cabin full of smoke, not the cause.

If you do as Hedd suggests you could refine the idea with a seperator and catch tank assembly , thus allowing you to pour the oil back in again .

Before I Did my pistons I had this problem. Crankcase fumes are in the main caused by worn piston rings.I have an updraught carb, so i welded up the vent holes in the valve cover and drilled a 5/8 hole, welded on a tube that lined up with the orifice of the carb and this sucked the fumes into the engine.
