Gentlemen,

 

I would like the opinion of anyone who has worn out an engine regardless of oils used and change intervals. Chevy engines please. Crappy designs don't count.

 

I have just never heard of anyone wearing out an engine, at least under 400k.

 

Breaking an engine does not count, nor does overheat or other abuse. Just wearing out an engine with proper air filters, etc.

Would an engine needing freshening up, like a rebuild with new bearings, rings etc. count in your mind? Just curious what exactly you're looking to find out.

I have worn out quite a few engines over the years, why do you ask?

 

As a matter of fact I have one now that is worn out, and it has always had proper maintenance and has 189k.

Just trying to get an idea how long these things last. I suppose "freshening up" would count as long as it genuinely needed it. Say burning more than a qt every 2000 miles or so. New bearings and rings would count.

 

Thanks

The most miles that I have ever gotten out of a gas engine is 325,000 the lowest miles that I ever got out of and engine (without breaking something, we are talking just wore out) was 100,000, but that was back in the 80's, oil and filtration have certianly improved things.

 

I have a friend that has a 5.7 in a chevy truck that has almost 450K on it and he is trying to see exactly how long it will last, but technically it was wore out 100K miles ago, he is just trying to keep it going as long as he can.

I've pulled a motor at ~100,000 miles (5.3, 2000 model) and the cylinder walls looked wonderful, too bad a piston rod threw itself through the block.

298K on a little 2.2l when I sold it, not leaks, didnt burn anything. Put a new head on it at 260k due to head gasket.

Snapped a crankshaft in my C60 366 with about 50k on the ticker.... Could have been me snapping the clutch is what I am thinking thou. Edgewise 86 R10 305, with over 500k... Does not burn oil.

Wow, you broke a 366 truck motor. I'm impresed. That is the same block as the 454 derated to make it even more bulletproof. I guess nothing is perfect.

265,000 on a Toyota 22R from 1983. Still ran OK - leaked a little oil in spots. Don't know if that counts as a crappy design or not.

I personally have not had more than 168,000 in a 96 Izuzu Oasis minivan. It could have gone much longer before I got rid of it as it still ran like new. I have seen several stories of some GM trucks and vans going over 1,000,000 miles with just regular maintenance.

Can someone please define a 'worn out' engine for me? I have a silverado with 225,000 miles on it and it does not burn one drop of oil between my 5000 mile oil changes, and it still runs like new. There is a small VERY slow oil leak coming from the rear main seal, but I do not consider that to make the engine worn out, just a failing seal. As said earlier, we all would leak some if we had that many miles!

Your 225k silverado is not worn out.

 

Worn out = hard to start, low compression, low power , smokes like forest fire, rough idle and running, etc. I would not include leaks in this because seals can be easily replaced.

Haha, I guess I should clue ya in on how to kill it........ Hrm, all you have to do is drop the clutch with the chain tight, to a JD 650G attached to the other end..... I was being stupid.... I needed another dozer to pull it out..... I hung it up in a overly swampy ditch.... Anyways about 4k with the trannie in 1-1.... I heard al;sdjf apoushf iuash fliuasd hflkasdhlfksahf (best interpretation I can give), which was followed by me said MORON.... WHERE was your brain.... Replacement 366 was sourced (AKA GM) and installed.....

 

I ended up with a friend bring his dozer over and pulling it out....... But I got the ditch re-worked and its not a swamp anymore....... Just cost a couple extra grand.... Mainly for the engine I KILLED!!!

Edit: I have several GM's with well over 500k without anything but oil changes..... They do not burn oil!!! But I am a 3k or 6 months guy whichever occurs first. Also, towing rates are 1500 miles per oil change or 3 months.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      By rjgvt · Posted

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
