How to Adjust Hydraulic Roller Rocker Arms! (I.C.E. Method)

[@ARMAGEDDON2916]

This company makes great engines! Have one of their 383 strokers in my 69 Chevy C10 with a Edelbrock pro flo 4 EFI system and it runs great every time I drive it!

[@sarsavage]

You did a fantastic job explaining how to set valves

[@rono3045]

We did that one turn adjustment on our lifters and it ended up hanging the valves open and we had no compression, we ended up just going half turn and it worked

[@RobertCarcaterra]

Great info! Can I use this same method if the engine is in the and has been running? Most videos show new builds.

[@heavychevy2289]

Yes you can just use EOIC..exhaust opening adjust intake...intake closing adjust exhaust it's easy brother just make sure your lash is out but not to tight

[@stephensteigerwald2129]

VERY GOOD EXPLANATION. Thank you for that.

[@edcass9]

How do you adjust the guide plates to align the roller tip on the valve? Also how do you check your rocker geometry?

[@ironhorse127]

You call it ice. I go EOIC. Exhaust opening, Intake closing. Work out the same in the end

[@bracken.g8488]

okay so that is with studded rockers, what about typical rocker stands with bolts, you turn it 1/2 turn, now it isnt tight so how do you tighten a ls rocker bolt without adding preload?

[@haroldhirhalin1493]

Have your lifters been primed and bled?

[@josh2madden]

What lifters are you using?

[@robertsnellings2936]

So it doesn’t matter what stroke your on when the intake is opening, set the exhaust?

[@____MC____]

I just re did mine with this method.

[@haroldhirhalin1493]

Are lifters primed ?

[@sepasgozar]

. Thanks for sharing this video… But I am wondering if it would be same way for classic Marine GM 350 opposite direction (RH rotation) or different method??

[@ubethejudge69]

curious 7/16 bbc rocker studs , used in pontiacs when you want to run adjustable valve train. do you typically do more than 1/2 turn adjustments with hydr. lifters , say comp cam and crane for example? in your experience.

[@jasonbeason4780]

What does it do when you trim off the middle divider on the intake? How much do you take out?

[@mattmelaniecorrie2634]

good vid...what do the OEM chev roller lifters use for plunger travel? i assume you are using those type in this demo??

[@Quakeroats608]

Thanks for this video.Explained a lot and made it simple.

[@Tablesaw818]

After preload is set should there be any side to side movement?

[@ireb.7988]

hey bro! does this technique works even if my lifters are full with oil? (I HAD TO INSTALL 2 NEW PUSHRODS)

[@mantisushi]

I get less than an 8th of a turn and the valve opens, what do i do

[@HypocriticYT]

I have an LS1 engine with that tick. Adjusting the rocker should remove that tick?

[@tannermcclellan3021]

If your running a solid rail rocker set up yes. All ls motors from factory are set with a guide plate and use a 7.400 pushrod. 22ft pounds of torque on the bolts for rockers

[@HypocriticYT]

@@tannermcclellan3021 it's a stock engine with hydraulic lifters.

[@daredevildare3641]

Most of the time a tick is either a rocker or an exhaust leak, look at the manifold to head gasket and collector gasket and any flanges if you don’t see any black then adjust the rockers, make sure you do the procedure for an ls though I’m not sure if they are different

[@edfarmer154]

Ls is not adjustable. If that's the issue, you'll need to change pushrod length instead

[@19antman55]

So by locking down the rocker you actually added almost an other 1/4 turn= 1 1/4 turns from zero lash after lockdown???????

[@rotorblade9508]

I saw 45 degrees that's 1/8

[@19antman55]

@@rotorblade9508 almost 1 1/4 Okay 1 1/8 turns, regardless my BB Chev 396 roller cam and rockers would not run with that adjustment, I don't think 🤔

[@PaulCTownsend]

Why does a bigger rocker arm stud take more preload?

[@stephensteigerwald2129]

7/16 diameter rocker studs have a different thread pitch (course thread) than a 3/8" diameter rocker studs (fine thread) because of that difference in thread pitch, the distance the nut travels downward is less with the fine thread than the course thread. Results are, to get the same .080-.100" preload you have to turn the nut farther on the 3/8 stud than you would the 7/16" stud. Hope that helps you

Thanks for sharing

[@RobertCarcaterra]

sorry last post meant to say engine is in the car

[@reevesautomotivefarm9614]

That seems like an awful lot of preload, I've only ever heard of half or three quarters of a turn?

[@SteveV6206]

I've done 1/2 turn for a long time

[@jbrsps4811]

i do 5/8 then get the extra 1/8 from the "lockdown"

[@ironhorse127]

Agreed. 1 full turn is a lot

[@daredevildare3641]

@@ironhorse127I got a Haynes manual and it says small block 1 full turn big block 3/4 Turns, I’ve always done 1/2 turn though

[@dariusbrown5378]

@@daredevildare3641ever had any issues with 1/2 turn? I’m adjusting my small block tomorrow I was gone do the 1/2 turn like you mentioned

Too much preload...

[@LEETIGER-v8y]

There's no such thing as a hydraulic rocker arm

[@jerrycordova1971]

Yes huh there is

[@Scubasteve22]

Spin the pushrod. That wiggle the pushrod up and down is for amateurs.

[@robbygray9562]

Spin is inaccurate. I can spin a pushrod with preload. Cant wiggle the pushrod when preload is set!

[@Scubasteve22]

@@robbygray9562 do it how ever makes you feel good. But i can 100 percent tell you, I can tell when i get to zero lash, every time! 45 yrs with no failure, and no readjustment, ever...

Thanks for the video. Very informative and straight to the point.
