Eric - I wasn't aware that Mk II Spits had a pcv valve in the exhaust
manifold. That seems a little odd in that it normally would vent into the
intake, not exhaust manifold. Are you sure about your arrangement? It
seems to me that venting it into the exhaust manifold is no better than the
old fashioned dump tubes on some older cars.
In any case, you could always try plugging up the hole in the exhaust
manifold and then connecting the tube to the port on the air filter housing
(that is what you mean by a "dust cover", isn't it?). This would, I
believe, be the proper set up in any case.
