Some of the comments are truly amazing. Thank you Richard. You're a life saver.

I am currently rebuilding my L92 and you are helping me a lot. I wish you all the best.

So many people need this info, and have no clue they need it or why they need it or why length may change... Well described for laymen.

I actually needed this. Been building up an LR4 as my COVID project, and I'm nearly at the stage for doing this. Thanks Richard.

I think it would be helpful to explain what the spec should be and how to figure out what size pushrod you actually need

[ricardogranados]

Thank you so much Mr. Holdener. I've spent all day read and watching videos trying to figure this out. Everyone just says tighten till snug and don't explain further. I work construction installing up to 300 pound glass by hand so my grip makes "snug" different. Your video made it so much easier and clear. Wish I would have seen it this morning instead of 9pm. Lol

I watched the entire video. I heard you talk about a safety range for preload. But I did not hear what the safety range actually is for the number of turns.

Good tips in every video
You’re the LS 👑

Thanks for all the great content Richard, these are very helpful door answering questions I get from customers at the machine shop.

thanks man. im from uk and im leasrnign this as i want to venture into the V8 worls and i always wondered about pushrod legnths

[Tony-lujb]

I used the old comp cam video with you in it from years ago. Thanks for the videos.

Not dealing with this style rocker yet, mine is still apart, this video made it ridiculously easy to check them. Add in a felt tip sharpie to double check contact and I should be golden.

I use the two finger method as well 💪🏻 works very well

I use a length checker and go 1 ¼ turns and order that length from the checker pushrod.
IMO stay away from the short travel lifters. They're noisy and you don't need them to go to 8k rpm.

[tylertruitt]

this is a great video. I don't see many on pushrod length

[jaydubb]

I've used this method countless times

Just finshed see your video, hear is an improvment to your meathod. The only differance is that you figure out the thread pich. Then after you set the zero lash.
you mark with a paint marker one of the hex sides of the bolt. and a paint mark on the cyl. head. now you start counting number of full turns. remove wrench and then count # of flats of the bolt past the one turn mark.
Hears the math part
since the LS is a modern eng. we know the thread pitch is metric. If the therad pich is 1.5mm then every turn equals a length of 1.5 mm, also each flat past the full turn equals 1/6 of a turn.
using 1.5 mm per turn ÷ 1/6 = [ 1.5 ÷ 6 ] = 0.25 mm per flat.
With your meathod and some math you can get a very close to acurate measurement.
Your fan always...

I love these videos. Sometimes back to basics is great to watch

Hi Richard, love your work. However, throughout the video, I see that the rocker pedestal (Tray) is upside down. Should it not be the right way up (with the writing not upside down) or doesn't matter?

[jimreal]

Fantastic....thank you for doing this video..you explain things well and at the perfect pace..so the guy who put 14 -7.5 pushrods in my ls and 2 - 7.4 under the other 2 rockers is wrong...had a brand new cam put in..a good one! And he says cam is different so it's ok to use 14 of one and 2 of other..I just had a bad feeling all the way home....I asked a few guys and they all scratched there heads..i now have to bring engine to machine shop because it just can't be right like this..If anyone knows, you do...thanks
