I have a friend who I talked into using a set of 3472 ez rollmax lifters in his street car. RB block bushed lifter bores, large feed hole bored into bushings.Nothing crazy for springs PSI 1224 springs.
He had called me during the summer to say he has had to set the lash a couple of times.Which is really strange because the same set up with other guys with almost the same set up except with a std unbushed roller lifter go a couple of summers without taking off a valve cover.
He tells me he only has 1500 miles on these new lifters.The only thing different between him and everyone else is he has not changed the oil since the lifters were put in.
His old red zone lifters had over 5000 miles on them with 5000 miles of hard driving and lots of oil changes (over 12 changes) and to be safe we figured send them back for a rebuild.
Long story short the bushings are worn on every lifter.Has anyone seen this before??
