Thread: Crane retro fit roller lifters?

Tweet

Hey guys gotta question. I'm freshening my 406 to help solve many issues. Last summer I installed an oil pan I had powder coated. The power coater used glass beads to prep the pan for powder. Well some of that crap was hiding in the crevasses and went through the motor. I ended up having the machine shop polish the crank. The main & rod bearings weren't in good shape. Machine shop said I was very lucky not to destroy my motor. The cam and cam bearings look perfect, not a mark on them. So, the six million dollar question, should I somehow flush the roller lifters, or since the upper part of the motor didn't show any signs of damage, would they be fine. I can't take them apart, due to the link bar rivet doesn't allow the cup to be removed. Another option, damn up the valley and prime the oil system and pull the motor through a couple revs and retrieve the spent oil? Another, fire it and immediately after change oil and filter. Maybe even do it a couple times?

nope they can not be re built or taken apart . buy new or keep using the ones you have .you never blast parts you can not clean out oil pans valley pans any thing with seams lap joints. the sand man is a bad man

Ouch!

That's a nasty shame - I concur with Pat, the sand man is evil when it comes to components that can not be really flushed. I'm assuming that you did a complete tear down and re-assemble - if not, I'd also be concerned about the area around the bottom of the distributor as there's some "nooks and crannies" there that can hide the little beads.

Sorry to hear about your not-so-good experience. Those Crane retro's are real pricey to replace, but that's the only sure way to know you've got all those little glass beads as they're impossible to see.

Good Luck on this one Keith!

I hope you pulled the engine and did a complete teardown and thorough cleaning. If not you spitting in the wind. And as cheap as cam bearings are why risk it.

Burned one,shy twice.I suggest a complete tear down,hot tank,gun brush all the oil feeds.I agree with Pat and think a build up from scratch in the long run is in your best interest.
Sorry to hear what happened.Those things when you try to do something good doesn't work out drives me nuts too.

Yes, I've completely torn this thing down and gone through everything.

the deal is if the lifters work ok then they just maybe fine .but if sand gets in the valving then there is nothing they can do to get the marks and wear out as it.s more cost effective to just buy a new set and know there not some thing ticking way getting ready to fail in time . really hard to say if they are fine. the way a SBC oils i would think see just as much junk go thru the lifter is as the oil thru the cam bearings. but your block should be priority oiling on that block you have . you could call crane see if they will take them apart clean them and put them back together . but i look in to this with another brand of hyd roller lifter they would not take them apart to rebuild... it was very hard just to get them to inspect for wear them finally they did .i would worry more about the axle pins and bearing s on the rollers them self as they see oil spalsh
