Ouch !

Glad you found one problem, that can be fixed. I like the idea of getting lifters that have a more robust clip, but the shape of the groove matters, so I don't believe you can just remove the round wire clip and replace it with a TrueArc. Find a lifter that comes with a TrueArc.

Buy some rare earth (neodymium) magnets. You'll be amazed how strong they are and they'll catch any and everything. I use small ones at the head drain back holes, larger ones in the lifter galley and large ones in the oil pan. I stick a couple on the oil filter too. The ones in the heads are generally covered in fine metal dust which i clean off whenever I adjust valves.
I ordered them on ebay but see that Home Depot had them last time I was there. Don't use refrigerator magnets, they're useless.

Re: Check it out...
 

I was wrong,thought it would lock up pump,guess gears were soft enough,to let it through,I would check distributor shaft,gear and replace oil pump shaft.
If you still have filter cut it apart and may find clip in it or in a oil galley somewhere since plug was gone under main cap. if not planning on it I would clean all galleys well replace cam bearings because trash could be in grooves behind them and no other way to remove it or check for it and try to find clip,you had metal go through bearings but not the whole clip,what has went through there is probably not much more than .005-.010'
Probably can polish crank have to be sure metal isn't raised on sides of groove,if grind crank .010-.020 more probably will still have some of groove left, groove there is about the same as groove in bearing,some cranks have grooves in rods and main journal for oil.

All good advice, thanks Mike. I would love to be able to stay with this crank but I'm a little leery. The rod journals are already -.030, so do you think the groove would be a weak point?

Re: Check it out...
 

radius next to counterweight is where strain is,groove like that most likely won't hurt it just have to be certain it isn't raised on sides,when it gets cut alot of times it raises metal on the sides that would mess up new bearing,if I was doing this I would show to my customer and get the OK from them,either they would leave it up to me or not want it like that, I won't use something like that for them to find later and not be happy about.
If you use it when putting back together after engine has been rotated check your bearing for scratching/scuffing if is OK I would check again before putting pan on,you can mic and feel of it but assembled and rotating engine will tell you for sure it is smooth enough.If regrind there is rods .040and .060 and mains .040, I would guess that .010 more on rods is probably still going to leave groove is only going to remove .005 off each side of journal

Paul, Honda rod journals are 1.880 and bearings are commonly available for use with Chevy rods.

Just sayin'...... ;) -Al

Re: Check it out...
 

Sounds attractive, but I scoured Clevite's catalog and don't see any bearing that would work with the 2.125" big end on the rods. Looks like that would involve new rods...and that ain't gonna happen!

Re: Check it out...
 

Yes you can just takes a little time

Re: Check it out...
 

I believe.070'' is most undersize legal in stock,I think some FE's are allowed more to use bbc journal

Paul, I figured 'ya for a small journal guy! ;). Clevite and King offer .050 and .060 undersize.....maybe that wouldn't be a bad way to go? -Al
