Piston slap is WAY blown out of proportion. It is a non-issue in terms of durability and performance. Sounds bad right at first, but it is not much more than a mild irritation. No evidence that it causes any real problems at all. That said, GM has gone to full-floating piston pins in its new LS2/4 engines because of the "perceived" quality issue.
I have one of those piston slapped trucks, eventually they DO lose power, and they DO burn more oil.
Not only do they sound horrible, but try to resell it, the noise scares people away and depreciates the value when you try to trade it in.
Been there, going through it!
Cold start it for a few days at the dealer. Listen closely for CSK !
Don't confuse CSK with so called "lifter tick". The tick is fuel pulsing thru rails and injectors and is quite present at idle.
Demand to take it for a overnite or more.
Have the service mgr. run a service report from the GM repair computer. This will show you ANY repairs or dealer complaints.
If no knock or service complaints...YOUR GOOD TO BUY!
Good meeting you and putting a face to the name.
ZBill,
I just did a complete replacement of rotors and disc pads @ 52k on my Y2K 2500. It wasn't because the pads were worn out but rather the rotors were the worst I have ever seen, nothing left to them on inboard sides all 4 wheels. The parking brake drum shoes were fine and still usable. I have never had a problem with the e-brake but could be because I use it all the time.

Try this link for info, but again see what your owners manual suggests. It depends are what type usage you do with vehicle also.

When I first saw this in CarAudio my mouth watered. The trouble is it's first generation, likely fraught with all the querks and glitches attendant. And, considering the pace of technology, it'll be leapfrogged in no time; Better, faster, smaller, more capable, etc., AND OEM.

I switched out my 245/75-16 junkyears for 265/75-16 A/T's. It reduced the power on my truck, but it does ride/handle much better. My dealer reprogrammed my speedometer for about $35.
I just purchased a new 2004 LS extended cab that I'm truly in love with but .. took it on it's first open road trip last weekend and a big problem raised it's ugly head. Once the speed reaches 50 m.p.h. and above the roof sounds just like hard rain does on a tin roof of a barn.
I know this seems strange but I had my oldest son with me and he felt all around the windshield, doors, and windows for air leakage and found NONE. I even check the antenna monuts on the roof (XM & Onstar) but they were not loose either ? So I'm stumped on this one, yes it's headed to the dealer tomorrow. I spoke with the service manager and he's never heard of such a thing either. I've been pulling a wrench for 30 years myself and this is a new one on me (especially with a new truck) ! It sounds just like your standing under an old tin roof of a barn during a rain storm.
If any of you folks have ever heard of this please let me know.
Thanks

If so thats the problem..................
In case of your Silverado, one of the mouldings may not be sealed properly and impact against the windshield frame as air speed increases.
Thanks for the info.
Any particular reason the bug screen could be causing this sound, I have bug screens on all of my trucks and have never encountered this before ? Maybe a difference in the cosmetic designs?
Thanks
BTW, I've got the same truck basically, 4.8L, 3.73, ext. cab 4x4. I probably wouldn't buy the 4.8L again, the 5.3 in my Tahoe is a much better motor IMHO. I don't think there's much difference in MPG either. The Tahoe always gets better mpg, but it's used on the highway more so it's not easy to compare. The truck usually doesn't average over 16mpg.
If no noise with it off....thats the problem!
Then you will do the windsheild surround reseal.
Search back thru this thread. There are posts on how to do it yourself.
Poss. one of the folks here who have done it can post and explain it fully for you.
EDIT......Check Mitzis post #4489 for the windsheild reseal TSB #
and give that to the dealer if you want them to fix it !
Thanks Mitzi........I missed your post on it !

Ryan, Bars look good, what happened to the old ones? Mine rusted thru and Westin sent me free replacements under their 5yr. warranty. I opted for the chrome version this time instead of black since they said the chrome version holds up better to the elements.

Heck, Just turned 5k miles. Been under the weather still but feeling better and still not driving much!
No dealer or warranty issues yet !............
Sometimes worth a couple more $$ to do it without any issues.
