In the market for roller lifters..
 

I'm looking into options for hyd roller lifters...what's everyone using?

cam...
278/288
.612/.618 lift
114 lobe separation

5500ish rpm...don't plan to spin it any harder than that

I do need the tiebar lifters so let's talk specifically about those please

Reason I'm looking long story short is I'm getting a tick in my freshly rebuilt motor and I think I have it narrowed down to a lifter either failing or just wore out not sure. They are comps that are in it and I think it's time to upgrade to something better.

Did you try adjusting the one that is ticking?? If its a fresh rebuild, one could need another 1/4 turn

Yes I have and it will go away slightly for a bit then it will come back...I've ran the engine about an hour now total and up to about 2500 RPM....kinda nervous to go more than that with the lifter/rocker ticking

What I think is happening is after I adjust the rockers it will run great no tick then I believe one of the lifters is collapsing causing the rocker to become loose and starting ticking/rattling

At this point I'm thinking of just putting new lifters in and know that's not my issue....I will admit these lifters I bought used but was told they hardly any run time and the engine builder looked them over and said there was no reason to buy new as these looked fine....well here I am now kicking myself for not buying new. Plus I've read that these comps are not great anyway and its making me a little leary to run them regardless

That's what I've been seeing that's why I started this...was going to get morels but saw numerous reports saying they are junk but also numerous reports of them being great....same with isky

Seems like comp went to hell in like 2012 or so from what I've read....I know all parts can fail but I guess I'm looking for the best percentage of success stories hahaha

I have used the Comp cams short travel race lifters in the last 4 engines that I have built and have been very happy with them. All of them had considerably more camshaft in them than what you are running.

Yea I'm pretty sure they hosed me on the cam...just started a separate thread about that lol

From what I saw comps seem to be the most economical choice...maybe I wasn't looking at the race ones you're referring to?

I guess nowadays any brand can be a crap shoot

whats the part # on these

Spoke with the clowns at the shop today and they want me to readjust all the valves and see if it goes away...the engine did sit for awhile while I was finishing up other things on the boat and they are thinking the lifters may have drained down and pumped up a little differently than they did when they originally set them...going to give it a shot before I rip into it even further and see what happens....thanks for the insight on the GM ones!! Will def check into them if the noise doesn't go away

I just dynoed a motor customer had built with the cheap factory dog bone lifters.630 lift, duration in the high 230s low 240s, buzzed it to 5800/6000 on dyno and never missed a beat. I dont know what spring pressures but stiffer than stock. Ive always been under impression they were done before that, Jimmy V specd these and says differently , since it worked, Im a believer, Smitty

Good to know thanks for sharing!!

I would like a part number for the lifters if anyone has it handy? Can't seem to find them?

Hey guys, OP has been asking about tie bar lifters.

As far as I know, many have been using the Johnson lifters, as Teague, Eddy Young, Isky, and others have been using/selling/etc instead of the Morels they all used to.

Well I reset lash on all the valves and it did help drastically but if you are very close to the engine listening for it you can hear a very very slight tick....At this point I have bigger problems so this issue will go on the back burner till the other issues are resolved...thanks for the info everyone!!

Which method did you use?

Took them down to zero lash by feeling pushrod/rotating it/moving up and down etc. then tightened the rocker arm another 3/4 of a turn. They were set at 1/2 turn from what I could tell so I went a little more just to make sure they weren't too loose. This was at the guidance of the engine builder...I have lost faith in them however I'm not made of money and they told me that if I did this the way they want me to then they will still warranty it.

just a fyi,the comp short travel lifter gets 1/4 turn past zero lash,if you go past that the valves will be off the seat at higher rpm,s.that will cause all kind of problems.

I don't believe mine are the short travel ones you're talking about...I honestly don't know for sure but they just look like a regular roller lifter....silver not black...sorry for the ignorance but I really don't remember what they are other than being comp lol

these are what I have...I bought them used....I know I know I shouldn't have used them but the builder inspected them and said there's no reason not to use them and at the time I didn't want to drop the coin on new ones....hindsight obviously I should have but I'm here now :throw:
