Rotating the engine twice ensures that zero lash is found by eventually tightening on the camshafts base circle. I can see how this technique is useful in a shop where distractions occur as well as the DIYer enthusiast at home in his or her garage were interruptions are likely. This procedure works for flat as well as hydraulic roller camshafts with stamped or roller rockers with or without lock nuts. Two thumb up.

Great method. I just did this on my big block C10 this morning. Worked like a champ and way easier than any method I’ve used in this past.

Glad it helped

I love how you factored in the "getting interrupted" moment. I don’t recall ever building an engine start to finish, without being interrupted unless it’s on Christmas morning.

This is Awesome! I saw this method on another video for a 350 hydraulic lifters non roller cam. I tried did it and wow engine fired right up first round; it made a believer out of me 😎

Does this work with any engine other than a marine engine? Also do you use the lock Allen nut to lock all of the nuts? I didn’t see you lock them.

Thanks for the video and explanation!

Hi .. Thanks 👍🏽 just did my valves on my BBC sound good ✌🏽

Good video. I'll be running my rockers after my freshly rebuilt big block started to choke and back fire a bit after only a few hours after the rebuild.

Excellent

Getting ready to open up a pair of Gen 6 HP500 carbed motors to inspect lifters/springs. Do the lifter need to be dry or primed to use this method? By the way, that is a slick way to do it vs. the messy running motor oil going everywhere method LOL!

This worked great on my bbc s10! Can I use this same method on a sbc?

I've got a 351w where i did the valve adj. with the firing order, set the tdc on and on and now i can't even get the engine to idle...Very frustrating since I just spent a grand having timing set. Very frustrating for me...and it's always something for sure...

Thank you

Are the push rods supposed to spin when your done?

So my lifters were already ran on the engine. I just upgraded from stamped to full roller rockers. Does that change my preload

good info

What if you forget to put the half turn and then prime engine. Can you go back and add half turn

Can this procedure be done if I have already soaked my hydraulic lifters in oil overnight?

What happens if you turn a motor over and some of the rockets are too tight you loosen them back up a little bit

Must of got interrupted ! How do you plunge them in ??

What keeps the adjuster nut from backing off and.. do you have a video for establishing push rod length? Building a 460 with aftermarket heads and I need some help with pushrod length. Thank you

I also don’t get that he said now you can fit the covers. There must be a locknut or grub screw to lock the adjuster in place.

There is an allen screw in the top of the adjustment nut he tightened. You just hold the adjustment nut in place and tighten the allen screw. Then you can put on the valve covers.

I've got a 500 inch stroker bbc in my 70 chevelle it has Rhodes lifters in it and always has noise it drives me insane iv had 2 different people do a lash and still clicks and clacks gotta be something up !

Can this adjustment procedure still work after the engine has run? The hydraulic lifters probably have oil in them already. Thanks

There is no need to tighten until the pushrod stops spinning right? I’ve noticed a lot of people doing that here on KZread when doing 0 lash adjustment . I tried that method and it didn’t work .

That is correct. Only bring the jam nut down until there is zero up and down movement on the push rod. You will still be able to rotate the pushrod with your fingers.

@josephprice851

problem there is if the lifters are pumped up with oil this really only works when there is no oil in the lifter

I'm sure this would work with a solid lifter cam by just using the feeler gauge and adjusting to your proper lash instead of zero someone chime in if you know thats correct?

@finscreenname

In mine I just roll the rotor in the distributer around to just after the # cylinder firing and then did both intake and exhaust on that cylinder and just go through the firing order. I figure if it's supposed to fire at that spot the lifters have to be on the back side of the cam. With a motor on a stand like his I would do what he did but start at #1 and go around a quarter turn of the crank at a time doing each cylinder's lash until you get to all 8.

No, you need to use feeler gauges and adjust to correct lash.

If your using howard's max effort hydraulic roller lifters a 1/2 turn is to much about a 1/8 to 1/4 turn no more or valves will hang open .

Feeler gauges are not used when using hydraulic lifters , only when using solid lifters . It appears to be a roller cam but it's hydraulic .

Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all petrol stations to only one state operated central gas station per city. From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime.
