Longgevity of the 4.7 V8?

While there are certainly a LOT of 4x4s on the road today that'll go 500,000 miles, the thing that impresses me about my 4Runner is that we're basically talking 15 year old technology, yet there are no oil leaks or fluid leaks anywhere on the vehicle. The engine and transmission both are bone dry and all the seals seem to be holding up great. That makes me happy.

I guess the $1,200 leaking exhaust manifolds counteract this positive, however. :(

Maybe, but only if you equate a sound annoyance with a mechanical problem.

I've never seen a report of a thrown code, failed vehicle inspection, or bad CO test.

I haven't either...but I've had two different mechanics tell me that if the cracks are allowed to get big enough, it could start to affect the valves in that portion of the head. And that would be considered a mechanical problem. A bad one.

Eh, I think affecting the exhuast valves is stretching it some... you'll get funky O2/AFR readings/DTCs way before that and lose some performance due to the leaking oxygen... I really can't see how it'd really hurt the exhaust valves significantly enough to cause them to fail prematurely...
 
I have an '03 Sport 4x4 V8 with 170,000. Drives like the day I bought it. I am however about to do a transmission fluid flush on it.
 
It's worth it.

I picked up a 06 T4R V8 with 65k miles and 1 owner. You have plenty of power with the v8 where you can toss your T4r around effortlessly. Planning on keeping my T4R forever.
 
One problem with the 4.7L is that the transfer case may develop an oil leak at the actuator due to a lousy design of one of the actuator seals. It is a known problem on the 4R and GX470 (search here and clublexus.com) and the GX470 has a TSB for it. Cost to repair it ranges from $1200-$2000 if warranty has run out.

This is not limited to the 2UZ-FE equipped 4Runners, nor is it limited to the 4Runner, it also affects the Tacoma and FJ Cruisers as they use similar style transfercase actuators.

The issue is mostly agreed upon by everyone due to a lack of proper ownership practices, i.e. the previous or current owner is not exercising the 4WD system reguarly as indicated in their owners manual. Such an act would prevent the actuators from sticking (another common issue) and the seals from drying out as well as making sure the 4WD system functions properly.

In other words, the issue is because people don't read the owner's manual and/or do not properly maintain their vehicle by once a month exercising the 4WD system in Hi, Lo, and CDL positions for a short distance (100~300ft) to properly lubricate the transfercase and its components.
 
Guess you don't know how good these trucks hold their value. I'd offer him $6,700 or so.

since you put it like that, i do know. i
here is a current snapshot of what auction prices are and SOLD history


i bought mine for $5800 03 164k v8 sr5 with aftermarket leather and roof, recent 145k dealer installed transmission and dealer service records.

So yes i know what they going for. i would not offer anything until you get there and see it. its tacky to offer something on a vehicle sight unseen, you maybe short changing yourself.

Pricing differs from location. In GA that price is average.

Oh, and I'm not buying it. I bought mine in October 2011. In posted that for the OP.
 
wow this thread took off... anyway I finally have a bead on another one in mag gray. Hopefully I cna get to it before it is gone. 105k on the odo and it is a 2003
 
I have a 2004 Sport V8 I bought new. Best car I have ever owned. I now have 180,000 miles on it and it still drives like new. I can't even feel the idle.

Total issues so far, (1) a $3 O ring on the transfer case range selector started leaking. $600 in labor to change. (2) An A/C relay failed, bought a new one at the dealer for ~$60. (3) an overhead light burned out.

That's it.

But the sport's have a special suspension system called X-Reas that some people have experienced leaks with. At 180K mine does not leak and is OK.

The prices posted above must be from dealer wholesale auctions. Here in CA V8 4Runners go for twice that amount easily.
