I am leaning toward this Crower.. It shows to have high pressure oiling from the band down.

Interestingly, Crower insists on the HIPPO oiling for their bushed lifters:

I just got this two weeks ago. Maybe marketing and engineering aren't in sync?

Or break the bank and put Jesel rollers in. Very nice roller but have a crazy price tag attached.

Mine now have 185 passes. Lash stays on within .000 during most lash checks. 2-3 lifters may change .001" at each check. Heck that could be my feel. 300# seat, 800# open Comp .471 lobe, 1.7 T&D.

Like I said, we’ll be looking to hear what Isky has to say, but the fact is at this point that after 200 miles we have 16 lifters where the bushings are worn out.

The whole motor has been torn down to make sure any metal that may have been pumped through motor didn’t do any unseen damage.

Everything else was good.

The only issues were that the bushings and wheels on the lifters are shot, and the cam is scored up.........like what you’d expect to see if the wheels on the lifters were skidding instead of rolling.

Hopefully between Comp looking the cam over, and Isky looking the lifters over we can get a more definitive answer as to why this happened.

Paging Al Alguire...Do you happen to have any pics of the red zones you are using successfully in the b1 motor??? I'm curious to see which of the 3 or 4 different styles of body you are using with good results.

If he's running with pushrod oiling, it would have to be the "Chevy" style body.

The 3472-RH EZX's my customer has have no provision to oil the pushrod.

IMO, the bottom line is....... Is splash oiling going to sufficiently lube the bushings or not...... Because that's how the ones my customer has get oil in his OE 440 block.

I have been looking and looking for pics of my lifters out of the engine to no avail. These would be 3772-LO-180 w/ EZ-X Roller Option. There is a label indicating they were assembled in June of 2015. They were for sure the solid body and had a hole feeding the axis of the roller bearing. That I remember.

Also, my cam is a 1.050 base circle. Doug, do you happen to have the base circle of your cam handy? Could that have something to do with it as well?

FWIW I have had no oil pressure but that was only 20ish dyno pulls.

Those are raised pushrod seat, pushrod oiling, .180 offset.

Yep they are in the low deck with the MW Victors and Hughes 1.7's. I ordered pr oiling because in case we went to paired shaft at some point down the road.

I don't remember the base circle but the cam lobes are Comp RX1718 Intake XCX1866 Exhaust.

All else being equal, more lobe lift = smaller base circle.

3372-RHEZX with thousands of miles on them. Just sent em back and they said they were ok and didn't need to be rebuilt. 400 seat and 950 open.

They are made for pushrod oiling though..

I've sold a few sets of these over the years, never an issue before.
I felt these were really the go-to lifter for this application, street/strip 505 with about .650 lift, which is why I recommended them in the first place.

Efidart, do you know if yours have the oil feeds to the bushings like the ones in the pics from HardcoreB?

I've had this same issue with just about every mfg of lifters. What they say the lifters are like and what they actually ship are sometimes two different things. The catalog will say pushrod oiling and bushing oiling but when you get them you can see that they don't work that way.

I've had this issue with Crower and Comp. These days I don't believe anything the mfg tells me. I just order one pair of lifters and check them over and then order the rest of the set.

My guess is that most of the mfgs don't understand how a Mopar oiling system works so they just ship stuff that works in a Ford or a Chevy and call it good. Crane seems to be the exception. I've talked to the folks at Crane a few times and they actually seem to understand how to make a Mopar lifter. Not so sure about anyone else. Maybe Morel knows how to do it??

I have a set that are my spares now...would you like me to take some pics?

I don't think you can oil a bushing from splash. We all know a needle bearing needs much less oil than a bushing does.

Personally, I wanted bushing type rollers as far back as 1984 when I lost my first roller lifter. All the engineers I knew said you needed pressure fed oiling to do it. Then years later they came out with bushing lifters.

This is exactly what happened to me with brothers Iskenderian. Told them I wanted pressurized axle oiling, and sold me the 3472 RH w/o pressurized oiling. Called them back and he said that he would add the pressurized oiling, for a price.

They have so many lifter body options, I don't think they actually know themselves.

Went with them as delivered. Several thousand miles, no issue. Mine has the needles, and I have mild lobes and lollipop springs. 15 psi at idle in gear. FWIW

I think the "Red Zone" lifter came out around 2004.They were advertised as having pressurized oil to the needles.So I ordered a cam,lifters and springs for my HEMI after having a failure of the Comp 829 lifters.They sent the cam and springs and told me the lifters were to follow.We installed and degreed the cam and installed the springs.When the lifters came,there was an oil band in the body of the lifter,,,,but no orifice to allow pressurized oil into the lifter.I called Isky and got one of the 5 techs that I spoke with during the ordering process.I had repeatedly told them I was buying the Red Zones for that feature.That's when I was told the BBM lifters did NOT have that feature.
Well I made a stink and ended up with "Rich" that supposedly owned Isky.He offered to rebuild my NEW lifters and drill the body so I would have the option the lifters were supposed to have and would only charge me $125!! I informed him that they were advertised to have that option and should NOT be charged.He came back with,,,,we make those lifters for Jim Oddy and Jim said they weren't needed.I told him I'm not Jim with 5 engines as spares.He then told me to sent his s%$t back.If I had not installed the springs & cam I would have sent everything back.
Out of curiosity I dropped the lifters in and the link bar attaching the pairs hit the lifter boss on my mega block.
I sent the lifters back and bought Comp 848s that were an AMC application.They are on their 3rd rebuild.Because of the treatment from Isky I will NEVER buy their product again!
Because of their PR oiling capability I sent oil up the exhaust PR for a little extra oil on the exhaust springs.I also installed a set on my friends wedge,we both lost 15 lbs of OP.So I installed restrickers in the PRs and the 15 lbs came back.I have no clue how they make then now,but id does not matter.NO isky products for me.Comp has been good to me.
