    With the weight of these rigs I kept mine on pretty much the entire drive. The increase in RPM helps the rig get up and going! 

    I also use it almost always. My OD Off/on does not work though, so it helps the kick down when in the mountains. yeah, fuel economy sucks, but it sucks either way. just happy I have a little house on wheels

  2. Ideally, a mechanic would measure the clearances,  calculate the needed shims, remove both camshafts, and put it all back together with adjusted valves, new timing belt, cam seals, and a crank seal if needed. water pump and timing belt idler too if there's any sign of leakage out the weep hole and or the idler is noisy. You may end up spending $1000 if it needs everything, but you won't need to go back in like that for at least another 60K miles.

  3. Is it still in the shop? The valve clearance can be checked with nothing more than a feeler gauge and the tools it takes to get the valve covers off. I've seen these engines go 160,000 miles without a valve adjustment needed. A solid mechanic could perform the adjustment if needed without any special tools either. But, if the shop doesn't have an assortment of shims, then the shim thickness needed will have to be calculated and then ordered. Exhaust valves are the ones that tighten up first. Another thing I'd ask for is to have them make the clearance at the big end of the range. the clearance if I remember correctly is .007-.011'' for intakes and 009-013" for exhaust. I'd have them get as close to .013" as they can without going over. On these engines, a noisy valve is a happy valve.

  4. Not a mechanic anymore, but when I was, I worked at Toyota. I've probably rebuilt 100  3VZE engines.

     

    The rule of thumb was "it's never the computer"

     

    The roaring noise-check your fan clutch, maybe it's locked up

     

    the lack of power...

    you gotta check all the basics first. wet and dry compression test. valve clearance, air boots, air flow meter, timing belt, distributor base timing, plug wires (original?, arcing? ), fuel pressure

    Is the fuel filter plugged?

    is the fuel pump working?

    is there water in the fuel?

    does it have a blown head gasket?

    how many miles does the engine have?

    you can check for codes with a jumper wire in the DLC under the hood

    you can use the same jumper wire to power up the fuel pump

  5. saw a rub through like that once on a 22RE pickup. the temp gauge read high. after replacing the radiator, thermostat, fan clutch, water pump, I found the wire harness that comes up and through the intake to the injectors and senders was rubbed through. the only wire affected was the one to the gauge sender. one strand of wire was making just enough contact with ground to make the gauge go high.

  6. Food for thought to all of us...

    I worked on many Toyotas in the 10 years I wrenched there. Anytime I ever removed a fuel line, I would go back and loosen the gas cap. I don't know the physics of it, but if you leave the cap tight, fuel will leak out of the line you have off. Loosen the cap, and it can sit for a month with lines disconnected. I think the fuel expands and makes a slight pressure that pushes it out of the open line. With the cap loose, it just expands and contracts and any pressure just vents out the cap.

    I tried to get codes from jumping the DLC, CEL blinks no codes, OD Off does not come on at all. Isn't the OD master switch an input to the ECM? how does the voltage get to the switch if the bulb is between the fuse and the switch? I can't imagine they would push power to the switch through the computer and have power coming from the ignition switch and fuse too. I do not have the factory wiring diagram, only the page that was posted here, and going by that, I can't see how the switch could work if the bulb was open.

    if you look at the pattern select switch in the diagram, if it were open, you'd lose your ground to the switch. no light, no ECT Power function, right?

    on the OD2 main switch, when you close the switch, you'd be grounding a circuit with no power leg if the bulb was open, no? and if the power came from both sides, how could grounding the wire before the bulb (OD2 side) make the light work under any circumstances? it would be a short to ground.

    Have you checked to see if the O/D light bulb is good?

    I never took the instrument cluster apart to check the bulb, but I tried to make it work through the wires from the shifter. there's only 2, and I applied ground to both. but... it looks like from this diagram that if the bulb is out, the OD main switch will not get power

    2 thoughts - there is a situation where the engine rpm can drop and seem like a gear change. my warrior does not have a tach so I can not offer baseline data.

    also, IF you plan to drive into the mountains (thinking colorado) you DO want to be able to disengage the OD.  Going downhill, the use of OD off (ie 3rd gear) and the use of 2nd gear a, you e paramount.  Without them , you could have brake failure on long downgrades.  if you can't turn off the OD, 2nd gear would work but in some situations it will be frustrating.

    That's exactly what I was thinking, downhill will not be something I'm not looking forward to. gonna fix it before I go into any real mountain travels. thanks for the input!

    I'm pretty sure it is going into overdrive. the drop is about 350 rpm. I can also feel the lock up and see it on the tach, it is less of an rpm drop.

    a word on the OD button:  the only way to get feedback is if turning off the switch when the vehicle is actually in OD and observing a resultant downshift.  Assuming the OD light comes on when the ignition key is turned on and the idiot lights come on prior to engine start(including the OD annunciatior) ,  then I would guess the OD is armed and your OD switch on the shifter is screwed up. 

    well, the OD OFF light never comes on, even with the initial key on check. the diagram I posted is for a 4 cylinder A43D, not a A340E, which i think is the trans for the 3VZE. I took the plastic off and found a two wire connector coming directly from the shift lever. could not find the relay.

    The OD light is confusing when the light is on the OD is off. The OD button is monetary the ECM relay will not allow OD solenoid to open if the engine temp is too low. Check the engine 10 amp fuse if it's out the OD solenoid will not open and the OD will stay on. 

    I will check that fuse, but the engine fuse must run more than just the OD. In any case, I don't think the OD OFF light is confusing, it just doesn't work. the button is not momentary...it has an on (in) and off (out) position. I have overdrive. the light and the control of turning overdrive OFF is what I don't have.

    So, grounding terminals 3 or 4 energizes the relay coil and opens the relay switch, and turns off the overdrive, right? then if that's the case, wouldn't an open circuit at 2 (blown engine fuse) cause the OD NOT to work?

    I'm just saying, it looks to me like the schematic shows a normally closed relay contact (1&2) makes a complete circuit to run the solenoid. anything that opens that circuit, fuse, or grounding relay terms 3 or 4, would make the OD turn off.

    I'm thinking if I ground 3 on the relay, I will get my light back and be able to shut it off again. gonna go try that. Thank you all for the input. If that works, I will buy the shifter that's up on Ebay.

    Knob should not spin at all. My bet is the wire is broken. The knob spinning probably means the shifter is now junk. Here is one on ebay, at least the pic might help https://www.ebay.com/itm/1989-1990-1991-1992-93-94-95-Toyota-Pickup-Automatic-Column-Shifter-OD-Switch/153324682197?hash=item23b2dcfbd5:g:4E8AAOSwb15cK27N:sc:USPSFirstClass!97396!US!-1:rk:2:pf:0

    Thank you, I will probably buy that one. is the OD OFF light supposed to come on when you turn the key ON? would a broken wire at the switch make the light never come on?
