Nice video. I appreciate you taking the time to explain this. Something I like to do also is to use a paint pen and mark each rocker so I know its done in case I get interrupted in the process. I'd like to add also that it really doesn't matter the order you do it in, just that its done on the base circle. Thanks again man. God bless
Thank you sir!!
Yes I agree. Paint pen makes a big difference. After adjusting 16 valves things can get a bit confusing.
You have to be careful when using the turning method.. Its not zero lash when the pushrod doesnt turn anymore..its zero lash when u feel a very slight resistance when u are turning..not turning anymore means u have bottomed out the plunger in the lifter..hope that helps
I agree with the vertical slack method. The method of twisting the pushrod confused me. It kept turning with the same resistance past zero lash. This video was more informative than most websites that explained it. I have the Comp Cam Magnum roller tip rockers which make this adjustment very difficult because you get a false sense of pushrod tension with a socket.
thanks for watching and commenting
Minor note of safety for those about to try this at home, take the coil wire off before bumping the engine over.
Bizzhatesme Just a minor note. LoL
Bizzhatesme Or just adjust them with the engine running, to me its just faster.
I didn't know Father Guido Sarducci was a mechanic as well!

you're so dated!!! 99.7 % of the population has no idea who that is....lol
Remember this simple method. Exhaust opening, adjust intake Intake closing, adjust exhaust. Follow the firing order and its really easy.

Thanks for this video, I just had one of my scorpion 1.7 rockers come loose on my Chevelle, not sure why it came loose but I’ll use your method to adjust them all again. Thanks!
the one thing i will add to this video on the amount of lash/pre;load applied while adjusting depends on the lifters manufacturers recommended spec or on a stock oem vehcile say 90s obs chevy the service overhaul manual. 1/4 turn or 1/2 turn to 3/4 turn is a good basis for stock lifters,
I have performace or race specific hydraulic lifters be recommended to be set at ZERO lash or 1/8 turn passed zero.
using the starter to turn the engine over is a good way to do a quick check or re-adjust, in my opinion turning it over by hand gives you a little more control over valves opening and closing for better accuracy for setting lash. adjusting following the firing orderfor the engine is usually how i have done it.
exhaust just starts to open on #1 adjust intake lash, #8 exh open adjust intake lash on that cylinder etc down the firiing order, then #1 again you watch the intake valve open all the way just slightly passed max lift right as it is just as its about to start closing now adjust exh lash.
or you can do the ( ROCK & ADJUST METHOD) WITH cylinder running mates
thanks man, I used your video to do the Scorpion 1.6 rockers on my C1500
you took the effort to try make this video much appreciated
Jamal Cole thanks for watching
Thanks for the great video mate. Would definitely help a lot of people out . Jamal is right . You're just helping people out. Thanks.
I put a 1/2 turn on mine (289) , but this video was extremely helpful. Thanks
Thanks for watching
Assembly lube is only necessary on a new cam with flat tappet lifters..however i always soak lifters over night with oil..and just as a safety measure, i put assembly lube on roller lifters as well
like your explanation best, just ordered heavy duty roller tip rockers and poly lock set from Mondello for my 455 Olds. They say I can use my stock valve covers which I prefer the stock original look on the outside for stock show at meets,hiding all the nasty inside hehe
Thx
You did a great job explaining & nice video , god bless you.
kenneth rippy thank u
What's your opinion on adjusting the rockers while the engine is running? I would think it would be the most accurate. Just wondering as my engine has a little tick and I'm trying to figure out whether I should turn the crank by hand and adjust each valve or just turn it 1/4 to 1/2 turn after it stops ticking while running. My engine is a the 5.3L LM7 truck engine.
Edit: FYI it has 180,000 miles on it, if mileage matter on how I should go about it.
+LinusScrubTips ive done it both ways..i feel that engine off is more accurate for me..thanks for watching
Hi i picked up a 302 small block ford and I noticed that the valve diameter for the intake and exhuast are slightly different, the exhaust is a bit smaller than the intake valves, but the exhaust valves have lash caps on them. two of them are missing, the engine hasnt ran like this or anything but is it normal that the exhuast and intake valve diameters are different ? and Do i need those lash caps? should they be on all of the valves, or just the exhuast ones to make up for the diameter difference from the intake valves. Thanks
is it necessary to put assembly lube at the base of your lifters? I soaked them in oil for a lil bit..will that be ok?
Yeah thats kool..that tool thing is a good idea..hmmm something to think about lol
Roller or hydraulic. Hydraulic rods are solid. I just assembled a 350 .40 over with camel hump heads... hydraulic cam, lifters and rods.
Yeah, I'm stupid. you said lifters...
If those are poly locks, you're supposed to turn the nut 1/4 turn AFTER you tighten the allen bolt.
huh?
@@klowny1969
You never knew that? You tighten the nut to spec, tighten the set screw, then turn the nut 1/4 turn more. I noticed some guys don't do it, but most do. Maybe it's not a big deal.
Not feeler guage..he's talking about an offset box end wrench with a t-handle allen..they come in a set specifically made for adjusting rockers
Did you take off the ecm?
Nice Camaro
Saludos!
Ok ok... so the point of this is so the valve is completely closed when setting lash??? Ihavent done this on a push rod V8 so i gotta look this up
Thanks
Yesir..lifter has to be on the base circle of the cam lobe
Good I got your attention. Have you got into Pontiac 400 heads
ENLIGHTENED CHILD OF GOD THE OFFSET if i have any 400 heads? Nope sorry
klowny1969 Well my question is have you used double springs. I'm redoing my pontiac 6x heads the cam I'm using is 466-488 lift and it requires double springs. Had you ever had to use a cutting tool in order to use double springs. Thank you
ENLIGHTENED CHILD OF GOD THE OFFSET double springs are the same way..
sorry if it sounds like im trying to troll your video, but from what I know you are supposed to use a feeler gauge and set the lash at what the cam card says on a mechanical cam. and yes I actually run a solid cam on my engine and the actuall settings is somewhat debatable because a lot of people actually set them with less clearance than specified on the cam card. so in a way im not totally saying getting the engine to operating temp and setting it at zero is a bad idea but its just not what ive been taught
Yes u are correct..u cam do it that way too for mechanical lifters..thnx for watching
less lash more low end power/torque more lash higher end power
Yeah I was thought to use feeling gauges and go by the firing order idk what they clearance would be because I’ve only don diesels engines so idk if it the same for gas
When go a quarter turn my roller rockers still clatter should I go half a turn after zero lash? THANKS
Dickey Moore they shouldnt make noise..you probably did something wrong
I followed these direction to the extreme and still have a tick at 1100 Rpm. No tick at 750rpm. Should i do more than a quarter turn?
Nicholas Goolsby it's possible that you didnt get zero lash at the begining..or u were real close...u can go another quarter turn on all of them and see if it goes away..if not u might have another issue
klowny1969 ive had the heads redone, new lifters, and push rods. And a thumpr cam. Ill try another turn.
Nicholas Goolsby hopefully everything was done right and checked all the clearances..good luck
are your Scourpions Rocker Arms Noisy at idle?.
mine are alittle noisy..
They all make a little noise
I have a question my buddy over tighted the rocker arms and it war the under side of them will we tryed to seat time which as uk we couldn't because they we're way to tight but will this wear hurt anything
sorry i dont understand your question..are you asking me if overtightening rockers will hurt anything?
+klowny1969 in a way they wore the undersides of all my rocker arms from us trying to get it in time but I am saying will that wear harm the arms
+Chris Cole in it will bend push rods and suck but I am basically asking if over tighting. and turning over trying to time put the wear on them actually hurt the arms themselves
+Chris Cole ok i think i sort of understand your question..sounds like you installed rocker arms that should have been clearanced underneath to clear the spring retainers..this is done in high performance engines all the time..the answer to ur question is depends how much wear there was and how much is left on the rocker arm..i suggest getting rocker arms that are designed to clear most springs like comps ultra pro magnums..these work great for mild street engines
+klowny1969 I had to get new heads the valve springs were getting completely compressed so I had to get dirt aluminium heads these are different in design and they shouldn't rub at all and to answer Ur question basically the paint is wore off maybe maybe a little metal not much it isn't flat by any means
IF THE LIFTER IS NOT FULL OF OIL IT MAY LET THE PLUNGER GO DOWN SOME, IF THAT'S THE CASE, WHEN YOU GET FINISHED, THEN CRACK IT ,THE ROCKERARM MAY BE TO TITE, IF SO IT MAY BURN A VALVE, AND START MISSING, I HAVE HAD BETTER LUCK ADJUSTING THE VALVES WITH THE ENGINE RUNNING, IT A LITTLE MORE MESSY, JUST TIGHTEN THE ROCKERARMS DOWN UNTIL IT QUITS TAPPING, THEN GO ONE HALF TURN, DEPENDING ON THE CAM, THIS USUALLY WORKS OUT ABOUT RIGHT. NOTHING WORSE THAN BURNING A VALVE. REMEMBER IF THE PLUNGER IS HAVE WAY DOWN THE WHEN YOU OVER REV THE ENGINE IT CAN SWOLLER A VALVE.
could you do another video while engine is on
Thank you for sharing!
What about gen3 Ls motors?
Check out my video on how to do an LS swap..thanks and dont forget to subscribe
@@klowny1969 i’m already subscribed where’s that video?
Do u have to do it in the doring order? Or just done one side at a time?
Thanks buddy, made a lot of sense. I ca do mine now with some confidence :-)
Awesome glad I was able to help..thanks for watching
good video info
thanks dont forget to subscribe
Great video, thanks
Bob O thank u
they do it's called a feeler gauge. they are clearly marked and come in both SAE as well as metric ..
Use a torque wrench and hand turn the engine over. You'll be replacing a starter motor very soon.
ENLIGHTENED CHILD OF GOD THE OFFSET lol what?
Ok i have to be sure i state this because MOTORS are electric, its a damn engine man
LOL
What about motor cross
Or general motors
@dylanantalek2422 The original post is correct. GM may have made an electric motor at some point? Hell, they used to make Locomotives. But just because a company that deals with engines puts "motor" in their name doesn't mean that it's correct technically.
No bueno..
doesn't he go on, a lot of it is pointless and yes he has no feeler gauges I would have liked to hear it running at the end interesting
feeler guages? ? not for hydraulic lifters!
+klowny1969 sorry my mistake how stupid of me LOL
+jaguar420g lol np
Wow glad he is not working on my shit
Randy Justice and why is that?
Are you a little confused sometimes waste a lot of time talking but informative anyway
+James Holsinger thanks for watching..dont forget to subscribe ;)
+klowny1969 I Did
You have no idea what you are talking about. That is NOT how you adjust them with solid lifters.
Solid lifters? Did I say something about solid lifters?
Clown job
U R soo soo close in doing it right but still far far away 🤔
You know this is a gen 1 sbc, right?
