WHY IT BROKE! 4.8L LS LIFTER FIX!

LS LIFTER PROBLEMS? What caused the failure? Junkyard Turbo LS-We Got Lucky! Our 4.8L turbo test mule was headed for trouble. While replacing the worn-out lifter trays, we noticed damaged cam lobes and lifters. This happened once before, with the Compound Turbo test. What was causing the damage to the cam and lifters and how could we fix it?

Those trays disgust me.

I am just finishing my LS 6.0 turbo build and was ready to put my motor in next week. I am ordering new lifter trays before I button this thing up. Thank you for the heads up!!!!

More often than not guys and gals neglect to change out the lifter trays when replacing lifters and i for the life of me cannot understand why. It is an inexpensive preventative maintenance item that should be done. And only use GM OEM trays, no Ebay stuff, it matters.

Sloppy stage 2 versus the world cam test! Can't wait

[@gregsullivan7408]

Nope - I got new lifters, new trays, new cam, but just 20,000km later, it's very noisy again. Going back to the workshop. 😡 (I have an LS3 based Holden Caprice)

[@runescapersonutube]

Yup, definitely what caused the wear in the cam and lifter, switching to bar linked lifters would solve the issue compared to plastic litter trays that wear out and can bend with all the heat cycles

$25 for lifter trays, so change them any time you have a chance and they have a good amount of time on them.

Personally I blame squirrels

[@necrofool]

Makes me happy that I replaced the lifter trays when I cam swapped my junkyard 5.3l

[@chucksgarage7165]

Another option would be to use tie bar lifters and get rid of the trays altogether.

Always good to find the cause of a failure. Good lesson for all of us...thanks

I like watching someone that knows so much about GM motors tear into them, even as basic as it seems to you or I, there's someone out there who's having similar problems , but may seem like relocating continents to them. Until they watch Rich make it look as simple as taking the next breath of air. Good job man, keep em coming n I'll love to keep watching em

[@BEANS-O-MATICtransmissions]

I think that was a good find and most likely the contributing factor to high mileage failures like that.

[@thatgreenrcsb]

As cheap as these trays are, anytime I have the heads off, I swap them out.

[@dragbikedemon]

And that's cheap insurance! Thanks again for solid tech Richard!

What I love about your video is HOW you assembled the motor with finesse and explained WHY certain parts fail. These exciting motors will be much more appreciated content for step by step DIY engine builds and take out the fear of the unknown. Do a LS7 build next ! Thanks 🔧😼🔧

[@teamgmotorsports]

Soooo glad you did this video and pointed that out! This will help save countless motors!

Hi Richard. I’ve just got to say, I absolutely love what your doing on this channel. I’ve been absorbing as much LS knowledge as I possibly can lately. I’m building a twin turbo 6.0 engine for my AWD LS swapped 1963 falcon build. I feel like you have been guiding me along the way! Just wanted to give you a big shoutout!! Great stuff my friend!

[@charlesfear4606]

As always a plethora of useful knowledge! Richard it's a pleasure watching you in your element

man this is such a great channel.
