well for some reason i can't keep my lifters adjusted on the 383....

i have brand new sealed power roller lifters and trickflow 1 peice pushrods 7.200"

i had to get a small base circle cam and i am wondering if this is the cause for the lifters keeping bleeding off.....

i have adjusted them to 1 full turn after lash to 1/4 turn past lash.. they will get quite for a little bit and when i start it again bam there they start ticking again... i am severily frustrated and beg for some tutorial to what might be causing this!!

all help is appeciated!

thank you!

I had the same problem on my buddies car but it wasnt a roller. Try adjusting them when the car is running (yeah it sounds scary but it will work). Just make sure you get the clips to put on your rockers so you dont get oil everywhere and yes i mean everywhere!
-First remove one valve cover
-place your rocker clips on (i didnt do this but wish i did)
-start the motor
-back the rocker of till you hear it click really loud
-tighten it untill you dont hear it then go about 1/2 turn past
-do the same to the other vavles
-put the vave cover back on and move to the other side

By the way are the rocker nuts new?If not they can loosen up after a while.

GOOD LUCK

 

the roller rockers are crane gold race and made for center bolts with guideplates, or non self aligning.....

i have afr 190's and i think the problem may be due to the fact of the pushrod angle not lining up with the valve because of the machining......

my uncle was telling me about the oiling hole on the lifters having to match the oiling hole in the lifter bore.. but don't both sides of the lifter bore have these oiling holes?

ede, rb? thanks again everyone and hope to hear from yaz!

 

The oiling hole position shouldn't matter if the outer perimeter of the lifter body is grooved.

A small base circle cam with stock-length push rods? As long as you checked the valve train geometry, I guess it's O.K., but I wonder about that one.

 

well the valve markings look right on....... i'd like to adjust them while it's running but will the retainers work with the crane gold rockers? couldn't i just clean the rocker off and use a peice of tape to keep the oil from squirting?

it's obvious that adjusting them cold isn't going to do it.... i just can't figure out why they won't pump up like they should? the plunger won't budge when trying to push the pushrod down in it by hand so i know it had oil in them but they still have noise....

my friend has a sloid roller and his aren't that loud.....

 

do you have poly-locks on your motor?? if not get them, they are much easier to keep adjusted because they load the nuts to keep them in place.... when you adjust the lash, let the car sit over night so the lifters bleed off alittle. then loosed the lock inside the poly locks with the right size hex bit. put the nuts on the rocker studs, grab the pushrod in between your fingers and move it up and down while you tighten the nuts on. get it JUST until you can't move the pushrod up ands down anmore, but dont put pressure on them. them start with the wrench at 12 oclock and move it to 9 or 10. then take the hex wrench and tighten the lock down with some pressure. repeat 15 more times and you should be all set. I have never had a problem with mine, but I also did them with the intake manifold off which makes it 10 times easier cuz you can see the lifter and what you are doing.

 

huh?
dood, its rocker arms, not rocket science. Do it w/ the motor running and let the oil fly.

 

well when i set them like explained above they just keep bleeding off....... the jam nut screws into the rocker nut correct? if so i have them......

and i'd rather not get hot oil on me but thanks anyway! thats just somthing i'd like to pass on.. lol...

 

ok, I read over what you said again, and you say when you start it up they click... does it go away after a minute or two? because if it does than your lifters are just clean and they bleed out when the car is shut off, which isnt bad, and there really isnt too much you can do about it. Its if they continuously click that you have the problem. Even brand new cars click for a second or two when you start them. the lisfters need oil pressure to properly lash themselves.

 

from the time you start it till it's shuts off the are clicking like hell!!!!!


i have 60 psi according to my gauge inside which i have a melling m55a oil pump in her....... it's all brand new including the sender....

i think i will just got to 1 full turn after lash and be done with it.....

 

I had to go with .100 long push rods in my 383 with a 1.05 base circle cam. Running dart heads comp cam and roller lifters.

 

nah dude dont do that...thats a band-aid fix and it could come back to bite you..
you should only have to turn another 1/4 turn after lash...

are u sure its the lifters?..i mean not to call u stupid dude but gm had a qs9000 spill with there 2001-03 corvette, camaro/firebird,C/K trucks...
im copying this right from a gm factory bulletin source

Engine knocking that sounds like a collapsed lifter may be caused by a cut O-ring in the oil pump. The noise will be noticed when the engine is brand new and my be heard when the engine is cold, seem to diminish, then return as the engine warms up. The O-ring seal between the oil pump and the pick-up screen may be cut, causing aeration of the oil..

the air bubbles get into the lifters and cause them not to pump up..and having to over lash them to get the proper setting...

obviously not your motor...but why not check it out..your going crazy over this so whats one more thing to go crazy over?

seriously dude check it out..

 

trust me this aint a dimmished sound...... it's up top defanantly....

funny, i have a 1.050 base circle as well...... i wonder...

back when we first started her up at my college, my teacher took her up to 3000 and held it for like 2 minutes... i asked him why and he said to get the lifters to pump up......

well we had one that just wouldn't pump up so i had to adjust them.. i got them to tight and it started missing...... so i know it's in my power to get them close....

i also noticed that there are a crap load of bubbles on my oil dipstick...... i thought a while back i might have a blown head gasket but i wasn't losing coolant and my oil was clean as can be when i drained it.. so i put everything back together.....

i think they just need to be adjusted to 1 turn because of the lobe profiles will cause noise in itself.... it's a comp xe282hr cam with a 112 lsa.....

 

well dude there ya go...there were bubbles on your dipstick...
the noise will come from up top because its the lifters that are making the noise

the o-ring on the oil pump will allow air into the oil that is being pumped..that oil with bubbles in it go to the lifters and cause the lifter to not fully pump up to were you u adjusted it, so you hear the play...which is that ticking noise

the seal in the oil pump may be the problem but its affecting the lifters by not allowing them to fully fill will oil...

 

where is this o ring located anyway??

i bought a new milodon pick up to go with the pump.. i don't remember seeing a o ring... my pickup has been welded....

i just don't see how.... explain please dude.... you got me wondering now....

 

ok the oil pump body itself drives off the cam...the pickup bolts to the oil pump body and between them is the rubber o-ring seal...

if your pickup is welded on then there probly isnt a o-ring seal.. maybe theres a pinhole in the weld, because thats all it would take to suck air into the oil..


im not tryin to worry yah. im just givin you a different angle to look at things...

maybe it is a pushrod issue or the cam circle..maybe the lifters are faulty...but there were bubbles in your oil and that can only be one thing..air in your oil..and the only place to get air in your oil is were its pumped from...

maybe you have to much oil in the pan and the crank sloshes around in it, aerates the oil, and the oil is pumped to the lifters..

 

i know what your talking about now!!! it was made into the pickup...... the pickup was tacked on so i doubt it has that much air in it.. maybe a crap load of condensation? it's been sitting since febuary...
