Okey, i will do a leakdown test on it! Just to be sure! The whiter colored sparkplug could be a sign, even tho i cant se the leak! Thank you very mutch for your time and help!

The pvc system is with one of the valve covers connected by a hose to the air cleaner, and on the other valve cover i have the pvc valve that connects to the carburator (edelbrock)! I think that this is the way its supposed to be hocked up!? Its an edelbrock manifold, not really sure if it has the same fittings as the original one!?
