Sean, I am in DC so no pictures available. I have two sets of Iskys and one set of Crower bushed lifters and also use Jesel stuff in the Predator. Pretty sure all my iskys I have used look like the ones you have posted. Definitely never seen one like Dwayne has posted and 100% sure on that. And the Crowers look similar to the iskys you posted. They are ALL pushrod oil, I also have them in my 68 Camaro street car and they have been in there for years with no issues. Wish I could participate more but without seeing them in hand cant tell you..

Yes please, if you could also comment on your success and application that may help the thread.

Russ, when you said yours had the same body design as this set I'm working with I wondered if they had bushings or bearings.
Obviously the splash oiling is sufficient with the bearings....... That's what everything had for years........and I'm pretty sure if we would have gone with bearings in this set there wouldn't have been any issues.

The lifters are enroute to Isky, cam to Comp...... We'll see what the verdict is.

Not Russ here but, in the sets I have here, I do have BOTH styles of bodies with BOTH bushing and roller...it maybe be one possibity... by design the one style that is 'supposed' to be for bearing BUT gets 'upgraded' to a bushing during rebuild etc...some time after it initially leaves Isky initially.

There was no rebuilding of the set we have that failed.
They were bought new a couple months ago as 3472-RH EZX.


My personal "opinion" at this point is, the configuration for oiling on the lifters we have is not sufficient for the bushings.

Now, if there were several people who were running these same style lifters we have, also bushed, that also have the feed holes not being pressure fed most of the time........ And not having any issues with them, that would be a step towards me changing my opinion.

I'm really not looking to point any fingers at either Isky or Comp. I'm just trying find the cause of the problem so we can avoid it happening again.

So I am using this lifter in a Indy block, with pushrod oiling...

Judging by the witness marks on the lifter body, it appears that the lifter is way up in the bore at full lift.
Any feed holes in the oil band going to the axles?

Did you happen to notice if the oil feed hole above the axle is exposed when the lifter is on the base circle?

Since those lifters have an actual oil band, the pressurized oil supply is quite a bit closer to that axle feed hole.

Looks like that part number puts the pushrod oiling holes where they should be for a Mopar...... Parallel to the axle.

I'll get back to you this evening with more pics and do my best to answer your questions...

Sure. I have been watching this post from the beginning and did not post initially because mine have the bearings. When no one seemed to describe the lifter body that you put up, I thought I'd mention having the same body.

Must had a bad day as Andy's post spurred me to tell my whiny Isky story. Thought I'd finish with at least some info, albeit not on point.

I personally think it is reasonable to believe you have a lifter design issue there, and was not suggesting otherwise.

Bumping for GregsDart and anyone else. Greg, the oiling orifice is likely an oddball size so to find brass that will press-in may require some machining. I remember seeing a set of lifters that BoatRacer572?, with the Predator builds out in California, posted that had brass in them to restrict. Maybe he will offer what he did? But as Doug pointed out his system has the same orifice area using thinner oil and has very good pressure (not that it is correct, but it's working) As THAT thread was concluding maybe you have a smaller base circle and that has caused direct unrestricted presssureized orifice exposure.

Here is an update on what happened with the lifters from the start of this thread.

We never really got an answer as to why the bushings failed so quickly.
But, they did replace them with a different version that does have an oil band and edm feed hole from the band to the axles.
They also have the upgraded “speedway” bushings.

I had the customer prime the motor with the valley cover open, and he verified oil would ooze out around the wheels with the system under pressure.

No problems with these so far.

I sent back the cam and had it checked for hardness, it was fine, so I had them regrind it.

Mine are still running fine, 250 passes. Very little if any lash change on inspections. I don't know if I mentioned it but I had 1 fail at 80 passes. Sent them all back. Got them back a week later, no charge. Don't know what they did but I haven't had an issue since. Maybe they changed all the bushings? Don't know. The failed one was caught quickly on a lash check. gained .007" in 20 passes.
