Longgevity of the 4.7 V8?

[KaseyMcc]

How many miles do people have now? Any issues?

I was never a part of this thread before you revived it, but my 04 2UZFE has over 230,000 on it. Only thing wrong with it is the exhaust leak, which the tick subsides after warmed up. I bought mine two and a half years ago with 175,000 miles on it and can't say I've really babied it. Very very good drivetrain.

I’m past 220,000 and wheel it pretty hard. Outside of blowing Chinese CV’s I’ve had no issues at all. No manifold cracks on mine, all original exhaust too.

Regular maintenance is the key.

The thing is bullet proof. I just bought mine a couple of weeks ago at 139K miles and I looked it over thoroughly prior to buying it. The motor has zero leaks, runs smooth and quiet, and feels decently powerful.

First thing I did was change oil to make sure that it has Mobil 1 and put on a Toyota oil filter. I thrash this engine everytime I take it out and expect it to last no less than 250K miles.

I've had many different Ford 4.6 and 5.0L overhead cam motors and while those things are very durable engines when taken care of, the 32V Toyota V8 just feels and sounds smoother. It must be that Japanese precision!

Many ****s on the EPA for forcing Toyota to abandon this jewel of an engine.

... stop making me regret not getting a V8...

Engine should last 500k miles easy. The only things I didn't see mentioned.... Be sure to change the timing belt tensioner, idlers, water pump, and thermostat every 90-100k. The only other significant thing I can think of is the air injection pump issue on the VVTI engines, but you can just buy a pre2005 and avoid that. Other than that the UZ engine packages are basically bulletproof if you keep them cool.

According to that million mile Tundra video he only changed the timing belt twice. LOL

Timing belt wear is more related to the age of the belt and engine hours, less related to mileage. It's possible to do a lot of high speed highway driving and rack up tons of miles while acquiring a less-than average number of engine hours.

Yes, but they also said in thy video that he was almost always hauling a heavy load out back and/or towing as well

I would think mileage = engine hours.

 

[4Rnr4Evr]

1 engine hour at 1000rpm =/= 1 engine hour at 5000rpm.

Bought my 2008 V8 SR5 new in Feb. ‘09 and currently have 94,xxx mi on it, 90% of which are highway. Have an appointment Friday for the timing belt, H2O pump, thermostat & serpentine belt replacement.

This thing has been our rock. Survived five Minnesota winters in which the single vehicle I would have traded the T4R for would have been an H1. Can’t tell you how many “4WD” others I pulled out of snow banks over those five years. Did treat mine to weekly car washes though during Winter and Spring months to keep the rust away.

We own a 2014 MB ML350 also and I prefer the 4Runner for many reasons. Yes, the MB is “easier” to drive but the 4Runner has infinitely more personality, which I wouldn't trade for anything (but that H1).

I wanted a V8 in white with some specific options, had my local dealer find it and ultimately brought one to CA from a NV dealer who happened to get an exact match, and I wouldn’t change a thing.

I towed a filled-to-the-gills UHaul trailer from CA to MN, five MN to WY round trips, two MN/CA round trips and so far four CA/WY round trips. All of that on top of towing a 24’ Airstream up and down CA, a bunch of boats/accessory trailers/random other towables around CA and the thing is unstoppable.

I’ve driven 6cyl 4th Gens and while my 8cyl isn’t 25% more “powerful” than, it’s at least 100% more awesome than.

I turn 37 today and plan to drive mine until one of us dies.

I have not really seen anything bad about these motors. If you keep up the maintenance they seem to last much longer than most others. I am enjoying mine so far and hope to drive it well past 300k miles.

This. Just change the oil and they will run forever. My engine blow up was NOT because the engines are bad. It was because an some previous idiot put something in the radiator causing it to clog up, which then overheated the engine. Hence why I bought another V8 engine and fixed it all because I know this new/used (112k) engine will run forever now!

I always hated that previous idiot problem. I dealt with that on my 85 Toyota Celica. Had to pull and replace engine because he took it to a shady mechanic friend.

I saw some of your previous posts, have you got your 4runner driving again or are you still working on finishing the motor swap?

She is running again, but having a couple of issues due to me trying to save a couple of bucks and not doing better research on Fleabay 02 sensors (see link). Hopefully by Sat morning she will be sorted. Then on Sunday I'm going to flush the tranny and put the armor back on and call it a day! <crosses fingers that's how it goes>

It's usually (almost always) one of the parts the t-belt rides on that fails causing belt break or jump teeth, and potential damage. It's pointless imo to change a timing belt at 200k and not do the water pump, tensioner, idlers, etc.

I think it's pointless to change the timing belt without changing the waterpump no matter the mileage, it's right there and take a few minutes to do while all the stuff is off doing the belt, so why take any chances by not replacing it, if the water pump fails shortly after doing the timing belt the coolant will cause premature timing belt failure and we have at least one member here who had to replace his engine because of this very problem.

Unfortunately mine only made it to 208k miles. All scheduled services done at Toyota dealer. Drove home in the rain next day when I went to start it, it made a knocking noise and started leaking oil.

Sorry to hear about your ordeal. Did you find out what happened to the engine? What was the cause of the engine knock and leaking oil? What oil did you use at the time and the filter?
