Longest lasting engines.

[Ma70.Ent]

Well since I spend so much time on SupraForums Other Cars section, I like this section, so I'll just start up this topic. What cars/engines do you think are the longest lasting?

For me, I'd say the 22R/22RE, and anything that came with them.

 

[Big Wang Bandit]

My small block 400 in my chevy.

196k miles. Only thing ever done to it other than common maintinence is a new oil pan gasket.

 

[Mk3Jesse]

Chevy 5.7 350.
If you take care of them i have seen over 500,000+ miles stock engines..

 

[chopstickz]

5fse. 450k miles before an engine swap

 

[Sil]

4.9 L Straight six out of 8th and 9th gen F series, seen lot of em outlast the truck at 250k+

OM.616 3.0L inline 5-cyl Turbo-Diesel. Originally sold in the US in Mercedes W123's. These things are damn near impossible to break (harder than a 22R) and they get outstanding mileage. Oh, did I mention properly maintained ones regularly reach 300k+ miles? There are a few owners I have met that have driven them to 600k & 700k O_O. Definitely something there to be said about German engineering in the 70's and 80's.

I've seen 22R/REs go over 400k as well, but that's just a minor point. The durability of both the engines are really good though, haha.

Agreed. My '82 Celica retired with 1.6 MILLION km on the clock, that's pretty damn close to a million miles. I had to replace the bottom end once, it spun a bearing due to oil loss at about 750k miles.

Oh, and when it retired it was because I was attacked by a moose, and the SOB destroyed the body. The 22R was still running fine.

I read somewhere that the longest running engine was the v6 out of a 91-94 Maxima. I had a 92 that had 267,xxx miles, and ran perfect. Till a semi killed the car. It burnt maybe 1/4 quart of oil a month or so, but didn't smoke, and had lots of power.

Why doesn't the 7M last as long as these engines? (hehe)

I think a better thread would be..."What is the longest lasting 7M?"

LT1 and LS1

 

[Doward]

Not the LT1 - optispark kills that.

LS1 yes. Longetivity vs power, it is very hard to beat an LS1.

A20A1 is my recommendation for longest lasting engine. I've seen MANY 86-89 Accords with 300k+ and the body rusts out around the engine.

My neighbor had a 86 accord with some several houndred thousand miles on the original engine. Never burned oil, never gave him ANY trouble.

The body rust is another story....

 

[MDCmotorsports]

Cummins QSK19G. 48,000 hours + and still running strong.

 

[Mk3runner]

got 342,105 on my 92 accord f22a6 motor. still nothing compared to others but still.

 

[empera]

i had 296k on my 92 Acura Legend c32a

 

[super.secret.supra.club]

my 86.5 7m-ge. ran fine with a BHG. got it up to 353,XXX miles before i got into an accident the was forced to sell it the jusk yard.

Could be measured with an hourglass.....

 

[Tanya]

20R, 22R, 22RE, 5MGE, 4AGE, Datsun L28, Mopar 225cid slant 6, 318cid, 360cid (unfortunately, Mopar trannies suck), Chevy 305s are fairly durable...

...as boat anchors.

The 3406C Cat motor in my excavator has nearly 50k hours on it. The Detroit 4-71 in my old Hein Werner excavator broke the hour meter 15 years ago at 35,000 hours. It still runs stong and has never broke once in the 18 years I have owned it. Oil changes only.
The 6V-92T in a dump truck we had turned over 1 million miles before we sold it. Still running today. The 236 mack in a tandum mack dump truck I still have has 600,000 miles on it and runs very good still. Can't beat the older Diesel motors for life span.
For gas motors, the Massy fergeson 35 series and the flat head motors in pre 1955 ford 8 and 9n tractors are hard to beat.
