Breather Valve

Posted By : Angus MacLean, 02-Feb-2004, 09:54am

All GT6's and 2 litre Vitesses had a pressure regulating and one-way valve mounted on the inlet manifold, in the tube between the rocker cover and inlet manifold. This is an alloy casting with a circular (3in dia) flat steel cover secured with a wire clip. I need to obtain the control spring from within that is located under the diaphragm and operates on the plunger.
Background - My car, a 1600 Vitesse (with a 2 litre engine dressed to appear as a 1600) suffers badly from start-up death rattle so a spin-on oil filter was purchased. To provide sufficient clearance for this to be fitted, the 1600 standard crankcase breather pipe had to be removed and blanked off. Therefore, an alternative breather system is needed so as not to pressurise the crankcase and compromise crankshaft oil seals. A 2 litre standard closed circuit breather system appeared to be the solution but the spring is missing.
Question - Is this the best solution? Where can I obtain the spring?
Grateful for all responses.
