monifold leak
o.k. so i just finished a rebuild on my 86 and fired it up everything was great until it came out of its warm up cycle.then the idle started wandering .so i tracked it down to a leak from 3 of the injectors on the left bank.brand new accel injectors and a cleaned and bead blasted monifold.so i took everything back apart and got some oem o-rings from the dealer.put it all back together with plenty of lube on the o-rings and it still wanders and leaks from the left bank injectors.this is driving me crazy and i dont have any other ideas i need help and you guys always give good advise so please help thanks

is it possible the bead blasting changed the hole diameter, and you need a thicker o ring? or maybe it has left the mating surface rough preventing a good seal. do the bad three offer the same amount of resistance during insertion as the good ones? could there be some problem with the o ring mating surface on the injectors?
fwiw, froggy.
