You might have a set that are ok. Early on they were fine. Just got worse more recently. I got tired of yanking intakes to replace them. That’s why I went with solids.
Hopefully. I know you don't just **** on products, unless you see actual failures.
I won’t. When are you going to call Bill T. and tell him he apparently doesn’t know how to adjust hyd lifters?
Let us know when you get a hold of him. Thank you.
all this stuff about Bill is him using pre evo lifters. This is a discussion about the newest design, not the older design which he didn’t like. you also endorsed the old design. how about you call Bill and ask him if he’s tried the new evolution design.
or you can link me to where Bill says the Evo’s suck
I don’t think you even realize I’m defending a lifter YOU sold to Cristian … I’m on your side on this one…now is when you can do the forehead slap..DOH😂😂

why did you keep all these Evo problems a secret that you were having? pulling intakes? that’s 2 or more , yet you didn’t say a word here about it ….not even to Christian.
only when I said I’ve used them without issue…you jumped on me with all your problems

that’s weird. you’re full of crap, like usual
It wasn’t every set, richard cranium. And as mentioned I wasn’t having any issues with any of them early on. Ask Christian when he bought them from me. That might tell you something.
And I don’t remember our (mine and Christian) whole conversation, but I can tell you even today some guys are willing to take the chance with hydraulics, even though I tell them about my recent findings. It is what it is.

I needed lifters as the low mile set you sold me for cheap, I stupidly stored above a battery on the shelf in the basement. A couple are fine, potentially as a back up. You sold me these I want to say, the very beginning of 2022, about 3 years ago. We were all hoping these were the next great lifter and Edelbrock was releasing these heads shortly, here we are 3 years later. Hopefully I got a good set of lifters to use with these new heads.

never said it was every set…I said you apparently had an issue with several sets and had to pull
intakes to do whatever you did to fix them …you got sick of pulling intakes
that was kept a secret, until a couple days ago for some reason. you are here every day, several times a day…..but failed to mention the problems you had with the Evo’s?
It's a double edged sword. If you actually vocalize problems with a product, there is awareness that the manufacturer could fix it, OR they drop you as a dealer, taking other brands under the corporate umbrella with it. Olds parts are a dying market; I'm sure everyone would love to eliminate them from production.

^^^^^^^^ BINGO!
My Comp rep knew my findings. He denied anyone else having any problems, but he’s also Trovato’s rep as well so…….
In addition my main guy at Topline knows the issue I had with a few of their sets too so again…….
It’s refreshing to know that someone on here actually gets it. Thanks Bruce.
It's the new corporate model:
1- acquire well known and established company
2- cut quality to increase profit and please shareholders
3- leverage company's credit for cash via "loans"
4- close company and default on said loans
If you look around, it happens everywhere. The only recent resistance was the Gamestop debacle where a bunch of customers got together to stop it. That's right; gamer nerds are more dedicated than car guys.

the problem with that is the Evo is still out there doing great like it has been from the beginning .It’s a proven new design that has proven itself over and over
you keep going back to Bill and him not liking the OLD pre Evo design…they have nothing in common
when you told your rep about the problems you had, he probably dismissed it because you don’t know shyt. you’ve done nothing but bash Comp for years..this is just another one of your bashfests.
a perfect example of you not knowing shyt and not being able to figure things out is you also swore off flat tappets. how can I use the most aggressive flat tappet hydraulics available and never have a problem? but you’ll go online and tell everyone else they are junk.
of the four lifter designs, hyd&solid flats, solid&hyd roller…you have real issues with three out of four and swore off two of them and now say you’re only using solid rollers.
My buddy is building a 66 Vista Cruiser and Danny Lattimore is building the 496 engine. All this hydraulic roller lifter talk has us using a flat tappet hydraulic cam instead of the roller. I'm not an engine guy but in all of my years racing and restoring cars I've NEVER lost a flat tappet hydraulic cam/lifters.

you guys must be doing some secret voodoo magical stuff.
I’ve never had a fail either …I’ve used the most aggressive lobes available, much quicker ramps than any roller could ever be with 1.8 rockers and .675” lift on the intake up to 7000 rpm .
that cam and lifter combo was with used resurfaced GM lifters. 😳.
you keep going back to Bill and him not liking the OLD pre Evo design…they have nothing in common.
Bill, and others, have tried them all, just ask them.
And I’ve been using Comp cams stuff for quite some time now, years and years in fact. Only thing that I don’t support from them are their hyd rollers. And again I’m not alone.
Finally, don’t ASSume you know what my relationship is with my Comp guy. You’ll just make more of an *** of yourself.

you don’t support their hyd rollers? uh, you did…up until I said the new Evo’s are ok. then for the first time , you opened your yap and said they have issues
you were pushing the old clackety clacker comps and then you sold Cristian some of the new Evo’s... You can’t keep your lies straight.
the guy at Comp dismissed your crying and complaining because the problem you had was in your imagination..he told you no one else had problems, because that’s true.
There was a run of bad hydraulics out there in the past. Maybe they've changed things since then. I have a set of Morel link bar hydraulic rollers that I got from Bill when he did my engine that is still in the case on a shelf in my garage. These have less than a half hour of run time and zero miles on them. I hated how much they rattled no matter what oil I used or how I adjusted them. I called Bill up about it and he told me that he's tried Comp, Morel, etc. and he can't make any of them quiet. He told me, at the time, that all he does is BAM solids now. So the Morels are essentially a $600 paperweight.
I’ve used Howard’s quite a few times which are Morel..Howard’s told me that. I have another set coming for a spring build.
what kind of rattle are you talking about? the ones I’ve used aren’t silent but nobody is complaining. no customer of mine has said anything.
comparing them to an old school solid flat tappet sound, the Morels are very quiet

FOR THE LAST TIME, I SAID EARLY ON THEY WERE OK. Christ you’re dense!!!!!
something new that Comp does with their Evo lifter is every single lifter cartridge, what they call the HCT, hydraulic cartridge technology, is tested for leak down rate… every one, fully pressurized and leakdown tested before it’s mated to a lifter body.
you get 16 lifters that passed their leakdown rate test.
no lifter before has ever gone through that type of rigorous QC testing before you’ve got them
if anyone can find a problem with the Comp Evolution lifter through a google search, let me know…I can’t find anything. not a noise problem, not a failure problem, not a HP loss problem…it’s weird.
not even one..I see lots of happy customers though.
if you find something, post it here..I’m dying to read anything bad about these.
When I dissembled and cleaned my EVO lifters prior to assembly I found the check ball in one of the cartridges was not seating correctly. The spring had moved out of position and no longer held the check ball closed.
Here are some pictures of the cartridge cup however you really can't see that the check ball isn't seated.

You are something else! And not in a good way. Did you even look? Or did you not like what you found, proves you WRONG!
Some common issues reported with Comp Cams Evolution hydraulic roller lifters include: lifter noise upon startup, potential for lifter bleed-down issues under high-performance conditions, concerns about inconsistent lifter performance, and occasional reports of lifter failure, particularly when used with high spring pressures or in extreme engine conditions; some users have also mentioned issues with the lifters not properly compensating for valve lash, leading to ticking noises.
Key points about Comp Evo lifter problems:
Startup noise:
Many users have noted a noticeable ticking sound when starting the engine with Comp Evo lifters, which is often attributed to the design of the lifter itself.
Bleed down issues:
Under high RPM or aggressive cam profiles, the lifters may experience "bleed down" where they lose pressure, causing inconsistent valve timing.
Potential for failure:
In some cases, Comp Evo lifters have been reported to fail prematurely, especially when used in high-stress engine builds with very high spring pressures.
Fit and clearance concerns:
Ensuring proper lifter bore clearance and correct pushrod length is crucial to prevent issues with Comp Evo lifters.
What to do if you suspect issues with Comp Evo lifters:
Check for proper installation:
Verify that the lifters are installed correctly and that the correct pushrod length is being used.
Inspect the oil system:
Ensure adequate oil pressure and oil quality to properly lubricate the lifters.
Listen for unusual noises:
Pay attention to any ticking or knocking sounds that could indicate lifter problems.
Consult a professional:
If you suspect lifter issues, consult a qualified engine builder to diagnose the problem and determine the best course of action, which may involve replacing the lifters with a different brand or adjusting valve train components
you desperately needed to believe that bs 😂😂😂😂😂. it’s a fairy tale,,like your fairy tale.
did you suck Cristian into buying a different set of lifters yet? you got your evidence now.
Man you just can’t take the fact that you MAY not be the only one that hasn’t had any problems.
What are you 6 years old? Are you going to hold your breath and stomp your feet until everyone agrees with you? My god man grow up.

There more out there.
I believe that bs as much as I believe Mike Remmi. Here’s the actual thread to that question the guy asked about if anyone has used them..two responses and both said they were fine.
Nobody in than link said they had any issues ..the two sets used ,,he said they are pretty quiet and he is happy with them.
the bs you posted above isn’t there..where did you dig up that bs?

You are a hack!! Stop making yourself look like a jealous fool!! Keep looking! There are videos about some years the body wall where too thin. Not correctly assembled, Burrs on some of the internal parts, check valve ball not setting properly. Metal shavings in them.
Read all the comments in the Comp cam Evolution™ Hydraulic Roller Lifters own video!!! Not good, Junk. For all to see!!

good lord…you’re making my point for me. the problems mentioned in the vid and in the speed talk link are the PREVIOUS design to the Evolution… the Evo is the FIX to those problems 😂😂😂😂😂
those PREVIOUS ones were the ones Mike Remmi was endorsing and selling, and the ones the guys were having problems with.
so keep going, I gave you a job, and like the good little useful idiot….you’re helping me. you’re such a clown you don’t even know the speed talk link is talking about two different style lifters 😂😂😂
todays task is to find more non problem with the Evolution ok? go…….

I bought a set, 2+ years ago from Mark when they first came out. They are going in this Winter/Spring with a small hydraulic roller with the new 68cc Edelbrock heads. I have seen some positive and some negatives, like at least one major failure with these. It seems nearly everyone has moved onto solid rollers, even with hydraulic profiles. I am going to continue running VR1 10W30, probably switching to the synthetic version next year. Opinions, like I have to ask.
was the one major failure of these lifters the one posted on Classicolds by Fleming in his friends Pontiac back in 2022?
2024
We did have an issue with the lifters, I used the new Comp Evolution hydraulic rollers and we had significant trouble with the bleed down rates. We tried a number of different lashing strategies and just could not overcome the bleed downs to a point where we could rely on consistent valve lash.
Man you just can’t take the fact that you MAY not be the only one that hasn’t had any problems.
What are you 6 years old? Are you going to hold your breath and stomp your feet until everyone agrees with you? My god man grow up.
the only one stomping their feet is you…I’m not the one desperately trying to prove there’s a problem with a part, when I’ve never had that problem, like others who’ve used them..it’s positive feedback
so far you haven’t proven anything, no data, no proof, no links to anyone showing a problem..all you have so far in one guy on here “supposedly” saying he took one apart to clean the internals before using them , and supposedly discovered a ball spring issue..the pic doesn’t prove crap. Why pull each one apart to “clean” the internals? I’ve never done that and it’s not necessary. Did he end up using them after or not?
you didn’t ask him because you didn’t need to hear the answer..you only needed the problem.
highway star posted a link to speed talk where a guy is asking if anyone has used them . there were two sets used, both with positive results. they said they are quiet and liked them
one was in a big lift heavy valve train BBC marine engine, the other a Pontiac..both successful.
thank you Highway star!
here’s what’s childish..you constantly demanding and asking if I called Bill yet to prove you right. 😂😂😂😂 it’s not up to me to prove you right. that’s what a lazy person does in a debate.

Yes CANADIANOLDS are the such a master debater 😂😂😂😂
I only ran a set for the dyno, no long term use as of yet, I think my comp hyd lifters were pre Evo series, I seen a post on here where they failed, think flemming posted it if I remember. Other than that never heard of them failing. Maybe it was the way it was put together rather than the part.
that post by Flemming are the pre Evo design, they were 857-16. what’s the part number on yours? The Evo’s are 85701-16
i also doubted the lifter was the issue there…every lifter doesn’t just failed at the exact same time.
