The noise that I thought was around the crankshaft pulley was really a lifter about to go. So now I will get a new camshaft and lifters . Goodie, Only #3000.00 +. Learned this is a common problem with 5.3. Also cracked flywheels are common. Mine doesnt have that , YET. Kept oil changed and serviced right, Drove it good , no Hot rodding and this happens !! I know people that have 300.000 miles on these 5.3s and do very little if any service. Go figure..........

You wiped a roller cam?

Prices will vary a lot with location, shop reputation, etc. but I'm thinking that sounds like about double what I would expect. By no means am I downplaying the amount of work; the heads gotta come off to do the lifters.

Just find a low mileage short block or long block
And swap that in
$3k for all that is way to much considering I can get a good 5.3 short block for $250-350 all day long

Mixed bag. If the current engine is good other than the failed lifters (and -possibly- damaged cam), I say fix it and keep rolling. Probably also a good time to deal with the knock sensors as they're likely rusted up and waiting to fail.

A junkyard engine could have the same failed lifters if you can't hear it run first, or they could end up failing soon after. Seems like if you don't REALLY stay on top of oil changes with these engines, the lifters are what get you.

You are right though that running 5.3's are somewhat dime-a-dozen though again prices will vary by location.

I need to move where you are. I can't touch one here in Jersey for less than $1000, and that's with contacts in a family owned yard. Maybe I ought to think about driving up to you & buying a couple dozen and bring them back to Jersey...

I have a 4.8. Does this happen to them also? I am currently at 331,400 miles. The engine doesn't want to die

Summit has 5.3 crate engines from $3,100 to $3,800. That's a lot cheaper than paying $3,000 just for a cam and lifters.

I would buy a 2008-2013 6.2L from the wrecking yard &
"upgrade" before spending $3000 on a cam & lifter swap!!

This range on 6.2l did NOT have the stupid AFM system...

So this engine would bolt in, without any other mods needed?

Just DUNE it

I too had a lifter fail on an '03 5.3L in my Suburban. Always ran synthetic oil, and it never was abused. When I read about this "common" failure, I found out that some of the lifter keepers would warp over time and cause the lifter to not run true on the cam. This causes the roller to heat up and fail, damaging the cam also. I found a vendor that repaired the camshaft($75), and purchase 1 new lifter, and 4 new keepers. Total cash outlay was ~$350 for the repaired cam, new lifter, new gasket set (including head gaskets), head bolts, and keepers.

As for swapping to a 6.2L, while it's a direct bolt in replacement, there's a lot more to a swap than bolting the motor in place. If you found a 6.2L that uses the same computer and transmission as your 5.3L, then the swap should be pretty easy.
If you're trying to put a 6.2L in a '01 that had a throttle cable, you'll end up needing a custom tune and a beefed up (or replaced) transmission. If you did have an older vehicle with a throttle cable, the 6.0L from the same vintage truck is a pretty easy swap.
