Not a t4r, but a close relative!

Tomorrow I think I am going to grab a 94 regular cab pickup, 177k with the 22re. I figure the thing is pretty much the same as my 94 4runner besides the engine and the manual tranny. I know lots of you guys run the 22re, so I figured you might have some input. Test drove nice.

My only worry with the truck is a noise I can't quite pinpoint. Almost sounds like a slightly metallic sound, and the sound correlates to increasing acceleration. Timing chain scraping (just throwing out a guess)? Or something else? Seems like it is coming from the side of the engine, not where the timing cover is, but I know sometimes sounds are a bit misleading.

Although the seller claims the timing was done right before he bought it (approx. 20k ago), there is no paperwork and I am just going to assume it hasn't been and do it myself. If it is timing chain scraping or acting up should I stay away? I plan on bringing the stethoscope with tomorrow. Any other things I should watch out with this engine?

Really hoping this truck works out, so I can add a more fuel efficient yota to the family. Both the 3.slow and the tundra are killing the pocket book right now. Thank you for any advice/input, it is greatly appreciated!

if the price is right!

not sure on the noise, but if you can get if for a good price then snag it, but id look over everything in the motor, gaskets seals and all! i had a headgasket go out in my 22re, and i know 2 other people that also did. the 22re gets great mileage, especially if your not in a hurry.

Well, picked up that truck last night. It sure is slow on the highway, but it made the 20 minute drive home without incident. An especially good thing with no left blinker, an out headlight, heater blower and no plates Luckily, I think most of this rig's problems are cosmetic, so it should be an easy one to clean up and get running good.

Nice!

As for highway speeds, my 4Runner with the 22RE does 85 on the interstate no problem, and it's heavier than the pickup, and has all-terrain tires. Get that engine running smoothly and it won't be so slow. :bigok:

 

[ozzyleven]

Glad to hear it can do 85 haha! I got it up to 75 briefly but didn't want to exceed the speed limit because of the no plate situation. It sort of revved high I thought.

I was wondering how much gear oil do I need to change the 5-speed trans, both diffs and the t-case? I'm guessing they are the same size as the older 4runners. The Chilton's is saying about 4 gallons, but the Chilton's has been wrong many times...

Not sure if this a potential problem with the 22re (or if it's even the same noise you were hearing), but I just got my 4Runner (3.0) back from the shop to fix a similar noise. It was a rapid, light tapping noise that increased with acceleration. I also had increased exhaust noise, reduced power, and reduced gas mileage.

It turned out to be a split (as in split in half!) air injection valve. It's not a cheap fix - the part alone is $450, plus a few hours worth of labor to replace it. Hope this isn't the same issue your new truck has.

Haven't driven it a lot yet, but it seems like it has all the power a 4-cylinder should. Can't speak about gas mileage. PO claimed he was getting 28mpg highway. The engine sort of sounds like crap though. Seafoamed it today with no improvements. I plan on inspecting things further this weekend when I have time to pull the valve cover.

I don't think its a knock (not like one I have ever heard any ways) and its not quite a tap. To me it sounds like when your bike chain scrapes a poorly adjusted derailleur, but thats probably a poor way to describe it. If anyone wants to play name that sound, I put a video on youtube.
22re name that sound! - YouTube

Yikes Geolander! I hope its not that, but my luck, I probably bought a lemon of an engine that is getting ready to head south. Crossing my fingers that it isn't.

Found this on the 22r/e engine:

Every 80,000 to 140,000 miles the chain would sometimes stretch to the point that the hydraulic-operated chain tensioner can not take up any more slack. When this happens, the timing chain impacts the driver's side chain guide, breaking the plastic within a few hundred miles of driving and creating a noticeable chattering sound in the front of the engine, especially when cold. If the engine continues to be operated after the guide breaks the chain will stretch rapidly (an unfortunate characteristic of single row chains). The loose chain causes inaccurate ignition timing which usually results in noticeable rough running. In continued operation, the chain can jump a tooth on the drive sprocket or break entirely, with either case resulting in engine damage from valve-piston collisions.

That doesn't sound like the noise I was hearing, so I think you're clear on that front at least. Mine was a light, rapid tapping that you could hear pretty clearly from inside the car, accompanied by roaring exhaust (from exhaust gases leaking back through the valve).
