On the subject of non-interference engines... been thinking about a new Tacoma. Are either the 4 or 6 cylinder versions non-interference?

On a side note.. are any engines still using chains? I looked at the chain on my Mercedes (below). It is not only a chain, it is a wide chain.

 

there is a Vet in Medicine Hat Alberta Canada, Dr. Kent Fuson, any way he had a 1990 3.0 V6 3vz-e and in 2003 he had over 950,000kms with NO MAJO WORK or rebuilds done. heck by that time he still had not taken it in for it's head gasket recall. so how you drive is what decides how long your engine lasts.

 

I think you are correct. I'd add that not ever overheating that engine is key. in addition to regular oil changes. It may be that the gasket used on the original 3.0L engine was more susceptible to problems IF the engine is overheated due to whatever. This would explain all the anecdotal problems... and the recall.

 

Id have to go with either the VW 1.8 8 valve CIS-E or the Honda B16A motor... I had a 8v dub shrick 282 cam, 5 angle job, full race port on cis-e, put down 142 ponies on a Mustang Dyno 650, daily driven had more then 280k on it and ran like a raped ape... Ive seen the B16A with more then 400K on them and runnin cherry.. Boogity boo...

 

there are a couple that come to mind yes the 20/22r the vws arent to bad bud the valves always need adjustments, and the older 1600 and 1800 subaru engine's

 

When I rebuilt my 22r last year, everything was original, had almost 1/4 inch play in the pistons and it still ran fine, smoked like hell, but no noise or anything. Now I can let that thing rip at 5000-6000 rpm all day long. Between that or the inline 6 that were in land cruisers would win.

 

2.5 olds iron duke 4cyl,350 chevy and the toyota r series motors

 

very good motor but didn't early (first year) ones have head gasket problems?

the sbc is a given

i believe the 20r(more stout timing chain) and the 22r were better than the 22re, but i still think the 22re is awesome. mike

 

I am not sure if the 4 or 6 are (non) interference, but the new 5.7 l found in the tundra and new sequoia uses a chain

 

both the 4 and 6 in the new tacomas are chains and non interference motors that was a main determinate of me buying mine. The 4 is the same as in the old tacos just with a little more power.

 

Hmm, 2.8 (LD28) Datsun, 2.4 Disel (Hilux, LC, 4Runner, 2L). 350 LS1.
Probably alot of other engines out there who can run, but those are the engines I've seen run for miles on top of miles, I know of many hilux that have reached more than 1.000.000 miles. Aswell as the LD28, and of course the ol' VW motor... And then there is the 4.0l I6 motor from Toyota that was used in LC60. (I can't recall the engine number ATM, 1HZJ or something like that.)
I have 1KZ-T motor in my truck and it's been driven for 280.000 km and still running fine.
Also, I've seen 3VZ-E motors running past the 500k miles... heh.
Probably there are LOTS of engines out there who have proven to be reliable, but this is my experience...

 

Northstar based. Not very reliable, and very expensive to fix. The first 4 years they made them are famous for blowing head gaskets, and then you have to drop the engine to fix it since you have to timesert the block before bolting the head back on. Definitely on the list of engines that needs to be traded while it's still under warranty.

 

Nissan Z24.

Mine has 504k miles and going strong.

 

i have a 55 vw panel, original motor with over 100k on it(1200 cc all stock), not sure how many miles because it only has 5 digits, but it has excellent compression, and sat from the late 70s till about 2001, drained the oil, new oil filter(more strainer) plugs and valve adjustment, no carb rebuild no new wires or cap or rotor, and cranked right up, rebuilt the carb because it leaked from the shaft and new oil pump and been driving it since.

(eidit) ive got a buddie with a 71 bug with over 400k only normal maintance.

i hope my 22r will last as long as some of yours, but its only at 111k

 

i dont care about cars... only trucks I refuse to drive em. On my 3rd Toyota (x2 22re and x1 3vze) with a wrangler in the middle of that.

22RE Hands down the most reliable, enough power in the 1st gens w/ a 5 speed. Easy as pie to work on, the little you need to. I never want to drive anything else.

 

The often over looked 1960s gmc 305 v6.

My grandfather had 2 1966 gmc trucks with the 305 big block v6 one with over 570,000 miles on it when he retired. No major work done, just oil changes.

I know a few ranchers with the same engine still running strong today.

 

The Nissan VG30E 3.0 V6 is probably the best built V6 on the planet and was only surpassed by the VQ series engines.

The VG30 served in trucks, pathfinders, maximas, Quest minivans, and the venerable 300ZX. You could build those motors from mild to wild on stock head gaskets (to about 400HP) and many of those engines run to 300,000 miles. In trucks and SUVs they are matched up to very well geared 5-speeds.

For the same year of production versus The 22RE or 3VZE you find more original condition high mileage motors with the VG30's.

Visit the Nissan forums and you'll see, the engines are something they almost never complain about and always take for granted.

 

Hey Guys,

If it does not make power it will last "forever". Simple pysical principals that no auto manufacturer can seem to get around.

I figure 80-90 h.p. per liter is the "reliable" limit, beyond that You have an everyday driver problem. Some motors do it better then others.

The 22re does not make any power to speak of, so of course it lasts "forever", and it still has the dissimilar metal headgasket problem (iron,aluminium expansion rates w/headgasket inbetween). However the injection system is very stable.

G.M. Has proven beyond a reasonable doubt, that the small block chevy is the most reliable motor of all time. In its 265,283,305,307,327,350 and 400 c.i. configuration it is very hard to beat. Search 1 million mile Chevy.

My honarable mention would be the Toyota V-6, the one from the Cressida, the Buick even fire 3.8, I dont know of any bad VW motors, its the rest of the car that drove You nuts, the Audi 5 cyl. is grenade proof, yea I know its a VW, the volvo b24 is unbelievable (never seen a bad one), the Dodge slant 6 is right up there too, and last but not least is the Honda 1.5.

I may have forgotten a motor or two, but in My experience these motors have all Proven that they have what it takes to go 1 million plus.

Thanks Kiwi

 

350....diesel....a cummins

 

Scion(Toyota) 1.5 liter.

I've seen one that ran just perfect in a Scion xB with 300,000 miles. The owner never missed maintenance.
