2JZ

 

Cummins in-line 6 in various forms for the past 30 or so years.

 

Whatever was in my 90 Accord. 300+ miles and only needed oil.

 

VQ30DE. Most are horribly abused but still keep going.

This one has 240,000 miles. It had been horribly abused and was full of sludge when I got it. Cleaned it up using Marvel Mystery oil.

Coin test.

2jz, 4g63, rb26, VQ30 are some I can think of that are very strong and overly engineered. Great motors to have fun with.

 

Ford FE engines ....

427 High Riser


427 Tunnel Port


427 SOHC

 

Chevy 283. My dad had one go 300k

 

The old school small block chevy is a testament to the power of loose tolerances.

 

What makes a 22R/RE legendary? They had a crappy timing chain design and were underpowered.

My first truck had a 22R and the head gasket blew. My second truck had a 22RE with munched timing chain guides.

 

or like any diesel motor before emission laws ruined them.

 

Every Manu. small block if cared for. (and remember oil was horrible back then) Chrysler 318 (had one myself go 330K+ when sold) Ford 302 got over 250K on my own Fox (but overheated it and had do heads so rebuilt sooooo, cheating, I know) and Chevy 350. I didn't pesonally have a high mileage version of those but DID have a 4.3 (3/4 of one) that went over 300K.

edit: the Ford I6, 240/300

 

LS series are doing fine for the 'tight is right' view.

 

As far as Japanese go of course ours are going to go down as being one and i always thought highly of the Nissan 4, Z motor can't think of the family right off the bat but the one with 8 spark plugs.

 

Who knows, some people have a real hard on for that motor.

Chevy 6.0 iron-block has been amazingly durable, weak, but i would trust it for well over 250k miles in just about any platform it came in.

 

Ford 4.9 straight 6 that’s one helluva good lil motor.

 

I always thought if the 22R had a timing belt, it would have been perfect.
edit: and quieter.

 

The Datsun Nap-Z motors were outstanding for longevity; I had one that was driven for 225k miles, parked (with zero prep) for 5 years, then resurrected when I got my license and driven for another 50k before I sold it. Burned zero oil, started in all weather, and still ran like a top. Every single one I've ever seen has had high mileage with a rusted body and frame falling apart around a perfect running motor.

The Ford 300 I6 was nearly as reliable as the Chrysler /6, with the advantage of more torque due to their larger displacement.

Edit- The GM I6's of the 60's & 70's were reliable as well, but were pretty doggy compared to the Ford & Mopar engines.

 

Every LS motor produced. 2jz. 4g63t, Mazda rotary, Buick 3800, Honda b series, vr30ddtt, BMW 3.0. Ect

 

Yep the Gen 1 Small Block Chevy is still a very good engine , you can easily make 600hp with a stock crank and block and building one is still very cheap in price
