One of my 588 blower motors blows out the oil breather on valve cover makes a big mess and causes my blower belt to slip. It has a rubber tube that goes to a small holding tank. i assume to much pressure in case can a pressure relief value be installed. Any ideas would be appreciated

588 block
B&M Mega Blower
6 lbs of boost

tks again

leakdown test, something hurt ring seal. for now, put largest vent hose you can on to ;largest vented tank you can. Extend breathers taller if possible

Thanks for the followup
