No no e vac system. should I get one?



No... not with a full exhaust... a E-vac will pull a
max of 5"hg and with a exhaust for every inch of back
pressure you reduce the effectiveness by that same amount
so if the exhaust is greater than 5"hg it will pressurize
the crank case




Mr P,I thought the one way valve for the evac system would prevent that from occuring.



If you start backing up that heat, that valve wont
last for a minute
