I have a 1999 silverado extended cab short bed 4x4. It had the 4.8 originally. I have installed a 6.0 LQ4 from a 2004 yukon. I did NOT do this for racing purposes or anything like that, One of the...

Its not the piston slap, its a very faint lifter tick.. has not gotten any worse, but wonder why its there at all?

The engine has 130k on it, are the lifters or rockers prone to failing this early on the LS engines by chance? Heck, the 4.8 i pulled out had 235k on it and was fine, and i have seen MANY others...

I replaced the 4.8 with a 6.0 with 130k on it from a 2004 yukon into my 1999 ecsb 4x4. I love it and it runs awesome! Its been in there for around 4000 miles now. Uses no oil or anything, but it has...

I have a 1999 ecsb 4x4 with the 4.8. It now has 236,000 miles on it. I had one of the heater hose quick connects blow out on me yesterday, luckily i had a spare one with me. I started thinking about...

ok, i have a 1999 silverado that had a 4.8 originally, I swapped in a 6.0 from a 2004 yukon. I used my original intake from the 4.8, but used the 6.0 injectors. Is there any differences in the 1999...

1999 4.8 engine, anyone kn ow off hand what size the bolts are that hold the bellhousing to the engine? I have to pick some up to bolt the 4.8 to the engine stand..

Allen, I just stuck the old PCM in and it fixed the problems, the 4wd icon on the instrument cluster lit up and it shifted through the gears in 4-low, so its in the PCM...(btw, it was not a fun ride...

Its not the 411 because thats what i had you do the first time for me and all was well (except that charge light, which you fixed)..I know my truck doesnt have the pushbutton 4 wheel drive, it has...

Well, i found a more serious problem today.. We had some snow and ice, so i reached down and put it in 4-low, and i immediately noticed the 4 wheel drive indicator on the instrument cluster did not...

hmm, anyone on here rent those scan cables?

how do i do a live recording?

I wish there was a way to just record whats on the PCM instead of driving it and trying to write it all down while its happening..

farmtruc, i dont want a refund by any means, i was just hoping you could tweak it for better mileage..

Allen,
I ended up swapping in a 2004 lq4 into my truck because the 4.8 had a bad castech head on it, so i had yall do a retune to run the 6.0. Well, it runs fine and all but the mileage is...

Just did this 2 weeks ago and have been driving it everyday since. I went from a 4.8 to 6.0, but same thing. Its literally a direct swap out, no problems. I just used all the sensors from my old 4.8...

we got the 6.0 in a week ago and is doing good! Recap, i have a 1999 ecsb 4x4, originally with a 4.8 that had the leaky castech heads, so i swapped to a 6.0 to avoid getting any more bad heads since...

I got my 6.0 today from LKQ, and as normal with these LS engines, there are 2 exhaust manifold bolts broke off in the heads. On the first one i tried drilling into it and using an EZ out and it didnt...

I thought the 2004 intake would be a returnless fuel style? I was told to use my original 4.8 intake because of this..? Is this not right?

you may be right. I work at a cadillac dealer and remember something about the mexican built vs. american escalades, but it seems like one of the models, like the EXT escalade that is only built in...

Its a stock 2004 yukon 6.0. Ok, i HAVE to use my original 1999 4.8 intake, and your saying the 6.0 injectors are bigger, so will they have to be modded to fit into the old 4.8 intake or are they the...

I have a 1999 silverado with the 4.8. I am swapping in a 2004 6.0 from a yukon. From what ive read, the 1999 injectors were oddball, then 2000-up used the same injectors on the 4.8, 5.3, and the 6.0....

Heres the deal..I have a 1999 silverado extended cab short bed with the 4.8. This is our FAMILY vehicle. Well, turns out it has castech heads on it and with the mileage it has, its cheaper to just...

I have a 1999 silverado with the 4.8 and it has the bad castech heads and is leaking coolant into the oil, so, i am looking for a good quality used engine to drop in. Want to go with a 6.0 to avoid...

sorry about the topic mistake, supposed to be 4.8 to 6.0..
