Yes, all the LSx series engines (5.7ls1, 4.8, 5.3, 6.0) can experiance the same issues. There's really no kit to make a 5.3 into a 6.0. What people mean when they say to swap to the 6.0 is, they want you to take out the 5.3 and but a 6.0 and put it in your truck.

This, to me, is not cost effective when you can fix the existing engine.

 

So your sayin i should replace the lifters and guides. Even on a motor with 100k. I mean i guess its possible considering the truck has no loss is power really, it just sounds like a pos. Where can you purchase the guides and lifters through gm only?

 

Anyone know where i can get the guides and lifters?

 

100k miles on these engines is nothing. i have a 4.8 sitting in my driveway with 225k miles on it and it didnt burn a drop of oil when it was pulled out/swapped for a 6.0

 

You can find these at any of our sponsors or you can get them at GM.

 

Torque Wrench,
In this situation, is there a updated lifter and guide design that engines with this issue would benefit from? IE: LS7, LS6, L33? Part numbers? Are these any different in design from the lifters / guides from a LS1(5.7l), LM7(5.3l), LR4(4.8l), LQ4/9(6l/6l H.O.)? Ahhh, to be free of annoying engine noise.

 

Yeha mna...part # 17122490. It's the newest design change in the GM lifter. 12551162 is the guide part#. As far as what they changed...I don't know ....but I've installed several sets ans they seem to be performing with no problems.

 

What could this noise lead too down the road?
My truck as 160k miles on it and now i have a STS.
We will see how long it will last...

 

How much of a pain is it to install these? Say i was gonna keep the 5.3 and build it up what would be a good setup for a good lowend midrange powerplant. i like to play offroad and pull alot so.. And the same for a 6.0 what kinda stuff should i be lookin for.. Sorry for all the questions just trying to weigh my odds and get some good insights thanks to all who have helped so far

 

help anyone?
