Well Hell Just Froze Over

Chevys don't have engines that sludge up even with proper maintenance.

Um... actually mine was. If Dexcool slowly mixes with oil, the buffer additives can cause the oil to sludge. As soon as i fixed my cracked head, my oil did not sludge up anymore.

But I know what you are saying.

Don't overestimate the stupidity of the human race.
Someone will buy it.
For full asking price.
It'll break.
They'll take it back to the dealer and argue.
Dealer will convince said moron to pay for repairs.
Dealer makes $7k off a $500 ride in the first 6 months.

Dealers are not stupid. They know people.

My '93 Cadillac STS, and that Northstar engine, required "WOT" once every 2 months to clean out the carbon.

My dad would do that with his Buick Lucerne. Thing sounded very good.

My dad called that “Getting the cobs out.”

Gotta get the cobs out regularly.

Yeah, but the V-6 in Lexus and Toyota high end cars had small ports in the piston to reduce emissions. These would plug up and sludge the engine to the point it looked like black pudding.

You can't do it on catalyst cars but I had a little trick with skeeter beaters that had good compression when I ran a shop at the salvage yard. When they'd smoke from blow by, the rings might still have life but there's would be a glaze on the cylinder. I'd head out to the country and remove the air filter. Start the engine and by hand, run the throttle to about 80-90% of full throttle. Shake a can of Bon Ami cleanser into the carburetor. It would blow a huge cloud of white powder out the tail pipe. About 1/2 the time, it would quit smoking. If not, we'd either junk the car or replace the engine. This was on our cars, not customers. I told people what I did if they bought the car but nobody ever complained.

I believe GM had trouble with small parts on the lifters or something like that. Not that that led to sludge in GMs, but it did lead to lifter failure. Ford's had issues with oil ports plugging up in the cam phasers. All these issues seem to be mitigated if synthetic oil is used.

A little trivia.... An engine of a Formula 1 race car.... the piston gap thickness of top-dead-center is less than a sheet of copy paper.

Useful information indeed.

The only problems with Honda’s, especially Accords and Odyssey’s is that the transmissions implode at 100K miles. I would never own another one...ever

Except the 3 honda accords weve owned, with 2 going above 200k miles easily (my daily accord v6 auto coupe is in the 230k range, it replaced a v6 sedan of the same gen. Meanwhile, my tahoe (and my buddies yukon xl) both lost transmissions before 175k miles. I think you got your facts mixed up

212000 miles on a 4L60e 2002 Tahoe and still going.

My dad's 1997 Tahoe lost reverse. Apparently it was a broken sun shell. If you do not come to a complete stop and go directly into reverse, that can cause it to snap. Sounds weak, and it probably is, but if you always come to a complete stop before shifting into reverse, this may keep your transmission going and going and going.

08 acc 340k.... sold it last summer and i still see it puttin around...I think I tuned it up once, changed oil every 10-12k and never touched the trans...

We bought a new Infiniti...... But she still drove her old '99 infiniti to work, for about a year & a half because it was still perfect. We eventually sold it. It had almost 200,000 on it.

Both have the V-6 and the new one has rear wheel drive.

The older Infinitis were great cars. Not too much tech and ran great. The newer ones have way too much tech in them for my tastes.

I agree.... That's what we like about the 2016 QX50. An injected a 3.7 liter V-6 engine and the 6-speed transmission / rear drive. The last of the classic set-ups. 325 HP. & 370 Z suspension.

( And a SWEET Bose system !! )

Nope, don’t think I do. I’ve had a Surban and 2 Denali’s and never had an ounce of trouble with with one. I’ve also have had 6 Toyota’s that never gave me a problem
