Mileage Roll Call - 200 Series

[xeuxaz]

I don't know why this is a surprise. The 3UR engine doesn't forgive overheating. Once it's been overheated, it's essentially a ticking time bomb. Owners with higher mileage 3URs (especially in the 150k+ range) need to be proactive. Pay close attention to common weak points in the cooling system — the valley pan, radiator (Pre 2018 design), all coolant hoses (heatercore Ts, etc), and the water pump. Even minor leaks or early signs of failure in any of these components is death for the UR series engines. Routine inspection and preventative replacement could save us from a major repair down the road.

Most 200 series owners don't pay attention to this stuff at all. The valve spring stuff is also concerning but seems to be rare overall.

Original engine had 165k miles on it before a valve spring decided it had enough. Carnage ensued.

Found a donor from a 570. It had 70k miles on it. We’ve put around 3k miles on the donor.

I'd really like to get some "color" on both engine. Like, WTF happens, to 1st. Where did replacement come from and what WTF happen to it?

I've a 2011 w~/210k miles. With hole, in crankcase. It's Slee'd, with decent bones. I'm kicking around replacing the engine. Or parting it out.

If it was a 4.7L 2UZ. I find a good used 4.7 engine. Hands down used, better than 99% of rebuilt on the market.

5.7L 3UR, I've no clue as to what's best.

Watching the Care Care Nuts videos. I've concerns with 3UR.

Original engine "failed" at about 140,000 miles. That owner said he was highway driving and the engine started making a lot of racket.
He traded it to a Honda dealer and that dealer sold it at auction. The used car dealer that I bought it from bought the vehicle at auction and poorly installed a
questionable replacement "salvage" engine.
That dealer has gone quiet on me and will not respond regarding the history of the swapped in salvaged engine (not that it matters now).
The salvaged engine has now "failed" due to "retarded cam shaft timing" at around 145,000 miles and has very low compression in 5 of 8 cylinders.

Presently, I have a pristine 2014 body/interior/chassis with a fubar engine:

For Sale - 2014 LC (Silver w/ black interior) with Fubar Engine (i.e. needs engine)

Undercarriage and interior and exterior are top-shelf. But engine needs replacing or significant work. 145,000 miles Silver exterior, black interior - excellent condition. KO2's with excellent tread. Iron man front bumper with 12k winch. I am trying to determine the worth of this vehicle. I...

So these are ones over 200K. Seems only one head gasket failure, reported in this thread.

Is the youtube Care Care Nut, wrong? Saying there's all UR engines have issue with HG?

Everything fails on a bell curve. The HG failures that are shown "early" are the leading edge of that curve. Not enough 200s have made high enough mileage to fill the middle of the curve, and may never. (accidents, rust etc kill most Land Cruisers, not catastrophic part failure).

The odds of a HG failure increase with age and mileage, and coolant flushes only help push that out. Given infinite vehicle life otherwise, every HG will fail one day, but the middle of that curve is probably higher mileage than most 200s will ever see.

This + Cooling radiator failures not caught in time leading to warped blocks and subsequent HG failures

Looking at the 3UR V8, trying to get handle on longevity. I found this statement. Can anyone point to Toyota testing, that can be used to VET below statement?

The UR Engines Made The Second-Gen Tundra A Million-Mile Pickup Truck​

Engine5.7L V8 Gas
Horsepower381 hp @ 5,600 rpm
Torque401 lb-ft@ 3,600 rpm
Towing Capacity10,200 lbs
Fuel Economy13/17/14 MPG

One of the reasons the UR family is so dependable is that Toyota subjects the engine blocks to an X-ray scan to ensure they're on-spec. Aluminum alloys can warp and deform during the die-casting process, so Toyota used X-rays to ensure that these deformations weren't severe enough to compromise performance or longevity. Beyond this, the 3UR was extensively tested, subjected to more than 800,000 miles of durability testing before hitting mass production. And that doesn't mean sterile "best case scenario" lab testing. Toyota's durability testing has them recreating gravel roads, rough weather, snow, ice, desert, and flooding in order to ensure that their engines will last even when conditions aren't perfect.

are the valve spring issues common?

Been a few posts about this… unfortunately it’s a thing. Sometimes.

HG and now valve springs - thats a bummer


any way to tell or prevent VS givinf away?

I can remember less than a half dozen valve spring incidents in seven years reading this section. IIRC a recall was issued for other engines in the family, but not ours. There were microscopic pictures of the root cause, some issue with the grain structure of the steel in the spring.

100%

My 2014 just turned 150k and I had the entire cooling system overhauled - probably overkill. The service manager thought I was crazy and they had to call corporate for approval before starting the work. But I had them replace all the hoses, the water pump, the radiator and a big list of other stuff. I plan to drive this thing for at least another 100k so had no problem dropping the coin for peace of mind.

call corporate for approval?

was it their $ or your $?

I don't know the details of Toyota's internal processes but the sales manager told me that my request raised some eyebrows. I guess spending $10k to replace a bunch of parts that were operating okay at the time was a red flag for them? Not sure - but having blown a HG on my old LC while on a trip and getting stranded in UT for two weeks...well, it's a scenario I'd prefer not to repeat.

weird

dealers are usually like the women at the chicken ranch

they are always happy to take your money



glad you got a new HG - smart move

Toyota issued a massive valve spring recall for 138,000 vehicles 2008-2010, but the 3UR-FE was not one included. If it had been a remotely common issue, they would have included it.

you mean how no rx300 transmission recall was issued when they were failing left and right?

no 3.0 L oil sludge recall

LS500 V6TT failing since 2018, no recall issued till 6 years later when same motors failed in large numbers in tundra and lx600?

no valley plate coolant ever issues even though ISF, GSF, LC500 having these problems since 2008….

Don’t forget—no 200 series radiator recall, just a quiet redesign 10 years after the fact.

I guess it depends on what issues are widespread enough and occur before the warranty is up

 

[2001LC]

Was Toyota making corrects in engine design?

Any threads around, on 200 series engine changes thru the years, and variations between Japan & USA?

I'm looking at partsouq with 200 series VIN from 2008 to 2015. I see changes in part numbers (PN) for long block, short block and block Assy.
Block Assy:
2008 11401-39815 sub to 11401-39816.
2015 11401-39816, sub to 11401-39817 after 03 2010.

Anyone know why PN change?
Any more changes after 2015?
