Anyone get much past 300k on a 3rd gen 4runner?

[Devbot]

My 97 had between 380-390k when it was wrecked. Still running great, and I had thrown a supercharger, 2.1 pulley and 7th injector on it at around 265k. I drive my stuff hard, too. Keep up on the basics and the big stuff lasts really well.

That's pretty ballsy! I would give an arm and a leg to add a blower and 7th injector but I have a strong feeling, at the very least, my trans may not like the sudden kick in power and additional strain after 300k miles of riding n/a. Really thats the only thing keeping me from doing it - that, and the price superchargers are going for now :tape2::tape2:
Edit: didn't mean to bump an old post but whatever

I got 230 but having Trans problems

I have 230 engine runs great but having Trans problems now really love this truck but I might have to look for another one

Why not swap the trans? A rebuilt shouldn't cost more than a couple grand and a weekend of time - a used trans would be less than $1000 easily. Hell of a lot cheaper than a new vehicle, especially in this market.

Just spent $4k on my 2000 limited with 225,000. All new suspension wheels and tires - upgraded. (easy to do these days when you have others do the work). The truck is so solid I can't se any value in dropping $50k on a new one to match what I have. About all it needs is the typical head gasket.

I got 293k miles so far.

I rebuilt the engine at 267k and around 285-290k I had to repair the rear drivers lower control arm mount.

I'm currently at 317,482 and I daily drive it. Mine is an 01' SR5. I've done the usual maintenance pieces (LBJ's, timing belt/water pump and all associated items, radiator replacement, external trans cooler, some steering rack items, CV's, spark plugs, wires and coil packs) along with regular and more often than not, ahead of schedule Oil changes. Keeping it 5K and below.

I've been super diligent about changing fluids because 1. Why not and 2. I enjoy doing them. I think as long as you take care of these things then your rig will take care of you. I've been super fortunate over the years to have owned this rig and I my plans are to keep it forever. Its even been totaled in a hit and run and I still managed to get it back to normal operating condition. Just all depends on what you want to get out of it.

96Red 374k showing going strong when totaled 02-18 I'm sure it would still be going.

DIY engine rebuild or with a shop?

Currently sitting at roughly 310,800-ish miles on my rig. Has some issues with the valve train currently but nothing catastrophic, I expect that with a 21 year old truck. Just keep on top of your maintenance and it'll take care of you!

 

[brillo_76]

Anyone over 300k. Really should look into getting your valves adjusted. As after 250k .. some of these valves will need adjusted. It's normal wear and Tear though..

Nothing serious unless you don't do it. Then you can end up burning valves or cracking valve seats.

Well yeah, but I used those funds to repair the truck through a private person. Spent like $900 for parts, having them painted, then having them installed. And it took the dude 2 and a half months to paint and install a new driver door, driver side fender and flare and repair the rear driver door flare. Like wtf.

I was definitely fed up by the time I got it back but I was ecstatic at the same time because my true love had been restored again. And don't get me wrong, it's not perfect by ANY MEANS. You can tell the door and fender have newer paint on them when you look at the truck from the side. But it's all good. I'm just happy to still have my truck and to be able to daily drive it.

Is this a big time job? Like do I need to have it professionally done? Or is this a Sunday afternoon shadetree type job? If I recall correctly, I think [MENTION=120071]mtbtim[/MENTION] did a video on this exact topic at some point. But I don't really understand the purpose behind it and what it does/how it affects the engine's performance.
For the record, I've never had it done. But if it is necessary and relatively easy/inexpensive, yeah I'll take a swing at it.

 

[Reinout]

I'm at just about 375k on the original engine and transmission. Not sure of the clutch's age, but it passes the curb test. Needs TB/waterpump/etc. It's been sitting and isn't used too frequently these days.

Yes valve adjustments are a project and takes quite a bit of time. I haven't done one yet. But I have too on the one engine soon.

The valve clearance CHECK is ~30 minutes on top of a valve cover gasket replacement job. Might get 'er done in a day if you're quick with the wrench, otherwise plan for an easy weekend. At 190k, all of mine were in spec with only 1 even close to a limit.

I forget if the cams have to come out for the replacement, but I'd add another few hours if so. If it can be done with the cams in place, then an hour tops (assuming you have a good selection of shims on hand, else you'll be having to custom order once you get the old ones out and measured). The most complicated part is the math, taking your measurement, the difference to your desired measurement with the current shim (measured, some are marked but you always want to measure) and the difference needed (new shim size).


As for what it does: Too tight of a valve clearance means the engine can't breathe as well as possible (think asthma). Too loose of a clearance and you're going to be losing compression (ballon with a hole). Either of those get too far out and you're going to run into hard-start situations (usually hard to start when hot but starts easily when cold ~ can be the inverse though). You also run a risk of burning valves when too loose. I can tell an operation difference in my '66 Beetle engine as I get over 2k miles... has a 3k inspection/adjustment interval.

I have two 3rd gens - an '01 that I purchased new, and an '02 that I purchased two years ago as my daughter's first car. Both are non-sunroof Dorado Gold/Oak SR5 4WD autos.

The '01 has 516,700 miles and the '02 has 208,000 miles. Both on original engines & transmissions (I purchased the '02 from the original owner who I've known for years).

I do absolutely all of my own maintenance/repairs/upgrades. On the '01, I've done two timing belt jobs - one at 171,000 miles and the second at 350,000 miles. The third one is coming up soon. I am religious with 3,000-mile oil changes using Castrol GTX 5w/30 and a Toyota filter. Air filter and plugs replaced every 25,000 miles, and a full transmission flush every 100,000 miles.

I have a ridiculous amount of parts receipts since 2001 and refuse to add up what I've spent.

I figured the exchange of transmission fluid every 100K would extend the transmissions life.

Did you change the radiators on occasion? I change mine every 10 years on my autos just to make sure I keep the pink milkshake away.

516K is doing well.. Congrats.

 

[162435]

^ Yes, I've replaced the radiator a few times in the '01 (not just during the timing belt jobs). I installed a new Toyota unit in the '02 a few weeks ago - it was original and gave me nightmares.

Yeah I really need to get around to doing that.. Don't remind me! Haha. She still has good power all throughout the power-band and drives & starts fine. Probably will tackle it once I'm not super tight on money since I need to my my valve covers at the same time.
