Have a VC 202 which has been fitted with extractors many years ago due to a warped manifold, I have had to pull the extractors and inlet manifold off to replace a starter motor. I know on the original cast iron exhaust the inlet and exhaust manifolds were bolted together and there was a valve that let hot exhaust gases into the inlet manifold to warm the inlet manifold when the motor was cold, from what I remember that valve set-up was on the right of the carby. When I took off the manifolds I noticed that the exhaust people had blocked of the inlet into the inlet manifold with a thick steel plate, I thought yep I know why the did that, but then I noticed the same hole on the left side of the manifold which they have left uncovered, was wondering why they would have blanked off one side and left the other open. I don't think it matters as the inlet manifold appears to be a double skin type of casting and the holes or ports only appear to go to a chamber that is designed to heat the manifold on cold starts.
This car runs faultless during the warmer months but when the cold weather hits it tends to stall until up to temp due to having no heating of the inlet manifold. was wondering if these holes or ports could have something to do with the cold weather stalling. ie one blanked off the other open?
