Good evening,
I'm getting a small build up of oil in the inlet manifold of my standard 1979 Sprint. It is usually after a run and the car has been left to stand for a few hours. It burns off at start-up (a rather embarrassing smoke screen) but doesn't cause any other issues.
The oil collects where the carb mount bolts onto the inlet manifold. I suspect it is coming from the crankcase breather. I don't think excessive blow-by gases are the cause as the engine was recently professionally rebuilt, although I will compression test just to be sure. The crankcase ventilation system looks in order, although I can't find a PCV value and there isn't any gauze where the take-off pipe mounts to the rocker cover - Does anyone know if there should be one or both?
So in summary - Has anyone else had a similar issue and if so what was the cause?
Thank you in advance
