irondiezl3 is on a distinguished road
is it true of mmo

some forums online have people stating mmo and seafoam even more so will destroy seals gaskets anything rubber? r u serious do you think its true. i use mmo in my crankcase following manufacturers specifications of course but i love the stuff. to be honest it helps with the 3400 lifter tap in my opinion but if its possible to do damage screw that no more?
