Okay, this truck is a total loss. I bought it to save money. I bought it for $1500 with 210,000 miles on it (1990, auto, a/c, shortbox, 2wd)... since I bought it 6 months ago, I've spent nearly $7000 on it... $3000 of that was an engine rebuild, and that's where most of my problems are.
The guys put a rebuilt engine in it and the new engine is just as noisy as the old one. LOTS of valve train noise. I've had it back to them a bunch of times and they can't seem to find anything wrong, they think it sounds fine. But a local guy who knows toyotas pretty well says no way, it's way too noisy... and I agree, it's much noisier than any 22re I've heard.
So, all that brings me to this question: Can you buy 22re heads, prebuilt, online? All my problems seem to lie in the head of the engine.
Also, do you guys know of any solutions to a throttle body that is worn out to the point that "it can't be adjusted"?? (that according to the toyota dealer)
It idles rough, surges a bit at idle.... Overall, I'd like to shove it off a cliff....but advice will be taken graciously... thanks
read, read read... also adjusting the valve lash clearance does wonders. look on ebay for a good used throttle body. you may try a throttle body cleaner or seafoam. you can adjust the throttle body just not the iac valve. you cna also adjust the tps sensor and it will caus eproblems. look at your air box , on top is the maf meter and if the flap is stuck it will run like ass. clogged cat? fuel filter new wires, plugs, roter ,cap? clogged fuel injector, o2 sensor....
when they rebuild your engine they usually almost always use the original accessories meaning everything on the outside of the basic long block is reused. look at the factory service manual sticky above and read the piss out of it, also look at autozones site as they have the repair manual too.....
Well, when they rebuilt it they cleaned the injectors... Like I said, it's all valve train noise....
As for the throttle body, the dealer said that the fuel mixture adjustments were worn out and can't be adjusted. So basically I either adjust my idle rpm's up to make it idle smoother (this causes the deceleration surge problem) or I adjust the idle rpm's down and it idles rough.
It has a new cat, and it runs good (other than the valve train noise) once past idle... so that eliminates fuel filter. I think it's a fuel mixture problem....
I just want to quiet this turd down so I can sell it. I think I'm going to have to convince the engine rebuild place to put a new head on it.... that or buy a new one myself and do it just to sell it.
It's rare... automatic, a/c... hard to find around here... so I figure it's worth book.
I've had 2 of these. One was a 22r & the other a 22re.
The first one got noisy & my mech said it was the timing chain hitting against the timing chain cover. A new engine has plastic chain tensioners and a plastic chain guide but after a while they get worn throug or break and the chain hits against the side of the timing chain cover. Eventually it makes a hole in the cover and leaks oil.
The second one seemed to always be a little noisier than I would have liked. I bought it used with 87000 on it about 3 years ago. In June of 2005 I was fortunate enough to experience a BROKEN TIMING CHAIN in the 94 22RE at about 160,000. One of the side links on the chain cracked and it slipped a tooth. The dealer had to remove the head, and the timing chain cover which had to be replace since part of the casting was broken by the chain.
When we looked at the inside of the chain cover we could see a fair amount of wear on the side of the cover and the chain guides were gone. It is possible however that the chain guides could have been broken when the chain went.
Since the valves were kissed by the pistons all the valves had to be replaced, the head turned down, new head gasket set, timing chain, chain cover done at a dealership. . . . . . . . Chaching, Chaching, . . . . $1950.
Try to isolate where the noise is coming from by holding a tube or a pipe close to the timing chain cover at the front of the engine & put your ear to it. Move it along the valve cover & listen. ( Careful of the fan. )
If it's the chain guides you might change these relatively inexpensively by removing the chain cover and replacing the parts.
Decking The Head Can Also Cause Looseness In The Chain, His Engine Is New However The Ticking May Just Be Your Rocker Arms Are Worn Out.... Mist Of The Time They Reuse Them..
So, all that brings me to this question: Can you buy 22re heads, prebuilt, online? All my problems seem to lie in the head of the engine.
Yep, you sure can.
I just bought a prebuilt head from J and C Enterprises off ebay and it has made my valvetrain the quietest I have ever heard on a 22re engine.
They use SS O/S valves, heavier duty valve springs, and a Crane Stage 2 cam in the performance heads which is what I got. Crane recommends tighter valve lash than stock, .008/.010 vs .008/.012 stock. I think this is part of what makes it quieter, the SS valves the other.
I got prices of $250-260 to resurface my old head and put 4 new stock intake valves in it locally, and saw reman heads on ebay for $300 + shipping, and got this one from J and C for $399 which included shipping both ways (return core too).
I can tell it's running better, though it's not like a V8 engine swap. Overall I'm happy I went with it.
Here's a link to my auction. I'm sure if he doesn't have one like this on right now you could call him and get one.
As for the TB, do the '90 models have the old style TB or the new straight style?
If its the odl style it's supposed to be pretty easy to change it to the new one and supposed to make a good gain in performance too. I'll try to dig up a link.
Thanks guys.... I have no doubt the noise is coming from the valve train... I can hear it, and a mechanic listened with a stethoscope and verified it. I may have to tell the rebuild guys that I want THEM to replace the head.... we'll see how that goes over.
I don't care too much about performance gains, since I'm selling it.... I just don't want whoever comes to look at it (to buy) to say "Yeah, sure this was rebuilt...it sounds like a diesel."
ONE OTHER THING: If I replace the head, how hard is it? This truck has bled me dry already. I'm a decent shadetree mechanic.... can I keep my existing camshaft? Anyone know how many shop hours this job is? TIA
