Can hyd roller lifters "collapse"?
Hi Paul..
I went through this in October. One of my lifters was rather noisy out of the blue one day. I forgot the exact technical reason....but I did have a collapsed lifter. You'll know it if you have one. Mine was there no matter the rpm, cold, warm...it was just there.

Re: Can hyd roller lifters "collapse"? (JD 90 383)
as you can tell, I am having "issues".
I have "clack" no matter what I do with the rocker arm adjustment. I tried the running method, at idle, backed off till clack, add 1/4 turn. Still there. Added 1/4 more for total of 1/2, still clacks. Tried static method with lifters on base circle, 1/2 turn after zero, still clacks. Tried 3/4, still clacks.
then, took heads off, found many bad valve guides, replaced them all.
Heads back on, running method adjustment, still clacks! Sound really louder in the top center of the SR lid. It's not the EGR valve tho.
Car runs like crap. I think I have a SR leak too :rolleyes:
Does this sound like bad lifters? Thanx JD!

We tried all that stuff too. backing off the rockers, tightening them etc. The sound didn't exactly go along with the cam..but it was there no matter what.
What is the mileage on the current lifters? I saw no record of NEW ONE'S when my 383 was done...so I am assuming mine we're 109K old. I have new one's in there now(Sealed power ht2148) and they're nice n quiet. The bitch of it is, if it's all together for you now, the intake and the rest of that mess has to come off. Only way to do it. LOL my manifold was off three times last year. I think it wants to stay on this season though!(So far!!).
Keep us posted on what you find.

Re: Can hyd roller lifters "collapse"? (MSR)
Micheal, the thought definitely crossed my mind, but I don't have a dial indicator. Pushrods are plain jane pr's that never gave me a problem before. I'm guessing motor has approx 20K miles on it.

Paul, just for info....if you have a Harbor Freight outlet around you, they have them on sale for about $10 and the magnetic holder runs about another $10. Obviously they aren't the best qualtiy but for what you ar checking it would work just fine. I bought one to check run out on on some rotors. :yesnod:

Re: Can hyd roller lifters "collapse"? (ittlfly)
I had one fail on me with less than 500 miles on it. Ran it to about 6500 on night "following" a few buddies. ;) At low RPMs, it would sound like a very loud clacking sound (almost like rod knock. At 3000 rpm or hgher it would stay pumped up and had little noise. Replaced it with a new one and has worked flawlessly for a couple thousand miles now (at least the lifter has).

How did you locate the bad lifter/s
Thanks... Denver :seeya :flag

Re: Can hyd roller lifters "collapse"? (C4Crazy787)
If I recall correctly, I tried adjusting the rockers while the engine was running. If the noise changed, I found my bad lifter. You can generally locate the lifter front or back, but it does get hard to narrow which one the culprit is wthout pulling some stuff.
If your lifters have some miles on them, just get a whole new set since you have to pul the intake to swap even one of them. The only reason I just replaced my failed one is because I had so few miles on the whole set and the warranty would only replace the one and not the set.

Re: Can hyd roller lifters "collapse"? (Vette92)
:thumbs: Thanks, I will try another engine running lash adjustment to get the idle and noise a little better. I am planing to install a hot cam, I will go ahead and get new lifters then. I just need it to idle a little better. I think I'll be ok to run the bad lifter/s for now, just maybe take it easy. 48550 mile's on the beast.

Can hyd roller lifters "collapse"?
It's related to this topic....
How would you determine which lifter was the bad one OUT of the motor? I don't know how...but we goofed and mixed the bad lifter in to the mix with the good ones. :mad I don't need 15 good lifters laying around...and they we're either going to be placed on e-bay or here for sale.
The last thing I want to do is send someone the bad lifter though.
Is there a way to check which one was the noisy one?
Thanks!!

My GM manual says that the lifters are serviced as a unit (lots o help). I know you can tear down some nonroller lifters. Maybe someone will chime in??

I ordered a new Crane OE roller set from summit awhile ago. $170.00 ouch. I hope this fixes it. Thanx guys!

Re: Can hyd roller lifters "collapse"? (89 Paul in Cal)
Amazing how one can go bad in 500 miles. Like because of lack of oil/lubrication maybe?

Re: Can hyd roller lifters "collapse"? (89 Paul in Cal)
:seeya You probably could ruin one by running too much pre-load...could just be a bad part. You might check to see if the rocker stud is loose, or pulling out, especially if you run strong valve springs. As for running with one loose, you could bend the push rod, or punch a hole in the rocker. Just luck as to how long you could run it with out damage.

Re: Can hyd roller lifters "collapse"? (Curveit)
OK guy's pulled off a running adjustment in 2.5 hr's last night. I tried it at 1/4 turn, 1/2 turn, and 3/4 turn the idle never changed same old lope @ 700rpm.
The noise seamed less @ 1/4 turn so that's where I left it. :smash: I think my lifter's are ok.
Will 1.6 rr's give you a lopie idle??? Maybe I'am barking up the wrong tree with this idle thing? I got a few other things to check out (1 sparkplug missing both pucks) I down know if this helps anyone, but it's where I'am at now
