GM built all V8 engines bad

GM has built all cars/trucks with known bad engines. Do a search for silverado rod knock/bearing knock. The problem is two fold. They have crankshaft flex because of an improperly supported crank and the crank is flexing knocking against the bearings. They also have a teflon coated skirtless piston problem where the teflon wears off after the first 1000 miles and leaves the pistons out of tolerance. When you start the engine with either or both problems your will here a rattle/tick/knock. If you look at alldata for TSB's you will find almost every v8 they built since at least 98 shows a tsb for these issues. They also have an engine exchange program for those of us who [non-permissible content removed] loudly enough. They offered me a new engine or a fixed engine and 100k 6yr warranty bumper to bumper. They would not do that unless they had a problem.

Quick question for ya how many trucks have broke down or have had any performance losses due to this knocking tapping or whatever you wanna call it?

I have the version with spin on oil filter adapter & t-plug off drain. This would stop your morning ticking...
But to be perfectly honest, the damm thing is really loud, obnoxiously!!! So I'll sell it for half the new price. Let me know.
Still, may be the answer chevy was looking for.

far. Of course mine is last of the infamous 350 small blocks. ALso maybe the very loud
Flowmaster keeps knocking and pinging noises silent if there were such a thing. Funny thing is
I ve never had a Chevy vehicle ping, tick, ding, kock, cough, spit, miss since 1961
when i had my 265 cu in BelAire hartop.....Have had FORDS too, no problem there
either...hmmmmm
Ever built one? Even with all the assembly lube (sticky goey stuff) every decent builder pre-lubes off the oil pump. Now if it is so bad, why would they do this?
Read any ASE or ASME report on this, and you will understand. It isn't as bad as it sounds, just facts are facts, and the most damage you do to your engine (besides possible over-rev/ over taxing) is starting it.
of a permit. Millions of teens gettting licenses that year. My '55 had the 210 option, a
265 Cu inch V8 w/ 4bbl carb, powerglide, 45 rpm record player on the hump,
reverb, dual exhaust. Hood was nosed, and vehicle painted Diamond black enamel and
was very quick for a stocker. Turned 86 mph in 16 sec at Lyons Drag Strip, smoked
a 57 Ford Fairlane with 312-4V T-Bird engine. In those years gasolene was ultra high
octane leaded. In 70's and 80's i owned GMC, Chevy and Ford pick-ups. None ever
pinged when cold or going uphill under load. Those years were auto industry's worst
years for decent running cars.

Had a '64 Galaxie 500 with the 390. Could never tune that Carter 4bbl carb worth anything. Was a hard start from day 1 till 1970 when I finally got rid of it...no a/c either.....

The modern oils with the additives don't drain off completely,it leaves a film.
So forth & so on is kind of wishy washy.

BUT!
I've got a 99 K1500 Suburban (1/2 ton 4WD); I towed a 6500 lb travel trailer with two kids, stuff, my wife, and my 6'5" 285 lb self; We went thru Kansas at 70 m.p.h in 115 degree heat; The only thing I burned was fuel. In Denver, I went up to Estes Park, and hit an awful camp-site; Awful, because I had to BACK push my trailer into a site, that small valley between me and the site;
The 350 wasn't strong enough to push, my engine temp went up to 265! At that point, I pulled into a level pull through lot; I was kinda scared, but no worries! That 5.7L is a tank, so's the tranny, and everything else;
NOW, I've got a friend who lives in Ainsworth, NE (up by south dakota line) who got 450,000 outta his '89 burb; He swears by this little formula
1) change your oil every 2-2500 miles
2) use Phillps Trop Artic oil
that's my story; I do think you can get a lemon V8 (yuck that sounds awful to drink) in anything; but I've had good luck with mine;

Next time you are maneuvering your trailer - put your transfer case into 4-LO. That is one of the beauties of having 4WD. It makes maneuvering much easier on your engine and tranny.
