5.3 connecting rod #5 breaks

[RockySierra]

My 07 had piston slap from day one, 400 miles on her brand new, and plenty of others on here have posted of having it on their GMT900s as well.

Interesting... I've been on here pretty consistently since ~2008, and haven't read much about it. My '99 did it after sitting for a while, but none of the 07+ trucks I've driven (or friends) have it. I have read numerous posts re: valve ticking at startup, but not much about "piston slap". I guess I missed those, or it didn't catch my interest.

I've been off an on this board for the past 8 years and the issues date back that far. When the 07s/GMT-900s first came out, I remember distinctly a ton of posts from people upset about piston slap being present in these engines and not having gone away from the previous generation GMT-800s. The engines are pretty much the same, they just upped the power a bit with a few minor tweaks.

New to the forum and joined just for this reason, picked up a 2002 yukon XL with a #6 broken rod,5.3l, 244000 miles, trying to decide the best course of action from this point on.

Sounds like it's time for a new vehicle IMO.

You didn't pick up a vehicle....... you picked up a hobby...

[RockySierra]

get a jasper rebuilt motor if the rest of the vehicle is fine.

[ChevyTech77]

I wouldn't put a Jasper engine in my lawn mower, just saying.....from experiance.

 

Put an engine in it and run it.

Well I'm the 2001 5.3 #5 connecting rod broke 88500 miles I know nothing about who's is better, Jasper ECT. Do know I quoted Auto I Web $2360 3YR. 100,000MI. UNLIMITED MILE JASPER $3200.00 100,000 mi. 3yr. General Motors 50000 mi. 3yr. $3500.00 and Advanced sales group $2150.00 3yr. 100,000 mi. Anybody that remanufacture's a motor is bound to build one that does not with stand the test of time , the same as why did OUR connecting rod break ? I got mine up and running with a new remanufactered Auto I Web motor runs real nice , No piston slap but I bought my truck new and pistonslap did'nt start till 18000 miles. And cause it had less than 100,000 miles on it and I bought it new and who the heck knows why GENERAL MOTORS stepped up to the plate and are going to give me some help. Thank You GM. Let me say I'll be buying another GM cause of that . I did'nt mess around when I had mine installed I put new everything in with it belts, thromstate , water pump, plugs, wires , hoses were not going back in there for a long time I hope. GOOD Luck !!!!!

Earlier you posted that you got the Auto Web engine. This post appears to say that GM did something for you. Actually, your post reads like it was written after the party. Can you give us a sober version please?

[captianhook3]

Well maybe you should read it again, I did not slur my words , Try having someone explaining it to you.

I was referring to the writing style you use. You jump around topics, and speak in half sentences, perhaps someone will it to you.

 

Did not say you slurred your words. Said it looked like it was written by someone that had been partying too much. I was referring to the "not staying on topic" style of writing. Just like someone who has been drinking too much when they talk to you.

[tommydurk]

My thought too...some form of hydra-lock at some point, causing the rod to bend.

Doug........ not sure why you are having a problem with CaptainHook3' writing....... Maybe you missed the 1st post in the thread ....... Anyway... it all makes sense to me and not many of us are professional writers.....
