Hi guys, this has probably been discussed before, but i'd like to clarify if its ok to reuse a roller cam with its matching lifters on a new block? Will lifter bore wear be an issue with the old lifters in the new bores? How bout cam bearing wear on the cam?

Physically, the cam and lifters have maybe 20K on them and still look immaculate: no feel-able wear, just visibly there are marks on the lobes that are shinier where the rollers have contacted them. Its my understanding that roller cams are hardened, so not surprised bout no wear. But just questioning the lifters...

(comp cams roller)

Thanks

As long as the needle bearings in the lifters feel smooth with light oil like WD-40 lubing them then re- lube them up with a 30w oil and slap it all back together as your good to go!

And will add that if possible, you should maintain the original order of lifters to lobes. The order they were run in for the beginning of it's life.

Yes, there is usually very little wear, but there is some, and they do take a 'set' or 'seat'.

He's going over to a different block I think so it will not matter!

"As long as the needle bearings in the lifters feel smooth"

Related....and a quote by another, "I got about 10K out of the Comp lifters before a few roller wheels started to sound like gravel. One roller though was totally shot and ready to spit it's guts out causing a knock which is why I tore it down for inspection. I should have caught it earlier as in hindsight it could tell the lash was not keeping spec like it should have."

Sort of related, and my story. Not long ago I had my first solid roller lifter 'failure'. While checking the valve lash during a routine check we found one valve would not stay in place, the lash would open up slightly after short use. We removed the intake and found one Crower solid roller lifter where the wheel was ground flat enough it had got into the lifter body and it damaged the cam. We checked the valve spring pressure and all was fine, that was not the issue. All the other lifters checked out fine as far as being smooth rolling. We had no clue as to why. I sent the lifters to Crower and had them rebuilt.

Does Comp offer rebuild service ?

Note your mileage. We had about 5200 miles on the lifters.

Opps, I made comments before we determined what type of lifters.

Solid roller lifters or hydraulic roller lifters. My comments were concerning solid roller lifters. Sorry for any confusion.

Thank you guys for the input.

-yes i will maintain the order of lifters to cam lobes
-these are hydraulic roller lifters. Still ok to reuse?
-i've heard complaints about comp lifters, but these are circa 2002 vintage, and not sure if their quality has gone up or down since then...
-is it worth going to new lifters from another company?

Too bad Isky does not yet make a EZ roll hydro lifter for Pontiacs yet!

[tom s]

They out soured their hyd roller lifters

[steve25]

How's that if they do not make the one I am posting about?

[Steve C.]

EZ roll hydro lifter for Pontiacs ?

I have no clue about the link bar used on the EZ roll but years ago we used Isky Small Block Chevy solid roller lifters and ordered them with "Pontiac" link bars with the proper spacing. In our application the oil band location worked out fine with the cam in use. Again I'm talking about solid rollers, I have no clue about hyd rollers if that could be done.

Some years ago Ken at PPR was getting some Hyd roller lifters from Isky.They don't at this time sell Pontiac Hyd roller lifters.I was at their shop some month ago and was told they out source their Hyd roller lifters and had none for a Pontiac.I was asking as I was interested in a bushed Hyd roller lifter.I asked if they could do a set of SBC with Pontiac link bars and they told me they could not.FWIW,Tom

I am having my Crower HIPPO solid rollers converted to bushings right now. To do the bushings the lifter has to be HIPPO fed on both sides of the axle. Normal HIPPO lifters are only drilled on one side. I don't see why they couldn't do this with a hydraulic lifter.

The circa 2002 Comp lifters may be the era where we have seen quite a few axle failures. Enough for us to avoid them all together. I hear Comps latest Pontiac lifter is made somewhere else, and is a better lifter. I guess time will tell. I would investigate them more, and maybe think about something else before they possibly fail.

[HWYSTR455]

I have a set of the 'new' Comp HYD rollers, sourced from Butler, I called to order, and specifically asked about them. They are not old stock, are the 'new' ones, and was assured they will perform as expected.

But as Paul said, we will see. Time is the true test. And/or miles, really.

I use the Crower 66295H Severe-Duty solid roller lifters with High Pressure Pin Oiling. In May of last year I sent them to Crower and had them rebuild to Enduramax Bushed Bearing roller lifters- Includes new bearing, bushing and pin. The cost at the time was $478. Way less than half the cost of this type of new lifters.

These are not the 'regular' 66260 Pontiac solid roller lifters. Years ago it was stated on PY they were better material, better bearing and a larger oil hole compared to the 66260 lifters. That said, I've never confirmed that with Crower. I mention this because the cost to rebuild and convert the 'regular' lifters may be different.

Here is a link to Crower rebuild information:
