Toyota Pickup (pre-Tacoma) issues

  • I have a 95 with the 22re also. It had 36K miles when I bought it and has always seemed like it ran hot to me. I remember the first time I checked the oil, I thought I burned myself on the dipstick. I would say that if the gauge reads normal, and it's not boiling over, then I wouldn't worry about it.

    I have a 93 Toyota pickup, 3.0L 5spd manual, 279k miles. About half a month ago, whenever i would turn on the AC, about five minutes afterwards, water would begin dripping out of the floor vents. If i took any kind of decent turn or brake, a larger quantity of water would spill out, soaking the floorboard. Any ideas on the problem here. I have a Haynes manual for my truck, but can't find any help there. Thanks.
  • That sounds like you have a build up in your A/C drip line. Usually as condensation builds up on the evaporator the water will drip out of a small metal line from the bottom. If dirt or mold/mildew builds up in the line, then it has no where to go but up, and out of the next lowest relief point. That would probably be your floor vents. If you can find the drip line, (usually a small diameter metal line coming from the firewall under the hood, on the passenger side) then you can clean it out with a pipe cleaner or some kind of soft wire. If you do choose to clean it out yourself, be careful. If you run a piece of wire up the drip line too far, then you can damage the evaporator!! I had a friend with a Ford that had a similar problem, the mechanic charged him less than $50 to fix it. Might be worth taking it in to the shop.

    :) Sorry for email address. We found the short under the front end of the EFI where the harness splits. The trucks runs pretty good. It has 298,500 miles and burns or leaks any oil. Can any one tell me how to know if the timing chain needs replacing? Also looking for the best place to buy parts (body & mechanical).

    Thanks,
    Ray
  • As far as the timing chain, I'd say the fact that you're pushing 300K is the best way to tell. 300K is when I had the chain done on my truck, the mechanic showed it to me when I picked up my truck and it was fairly well worn. Other than that I have no idea how to tell without taking the chain out and measuring it. If you're looking for good body parts there's an all Yota junk yard in Ft Worth, TX they have over 2 dozen pre Tacoma trucks with good body parts, and engines and transmissions, too. If you're talking about smaller parts I usually stick with the larger chain stores like Napa, or O'reilleys.
  • OK here it is... 86 4x4 22re leaks a ton of oil out of the front of the engine. I talked to a guy who has worked at a oil change/tune-up shop for 10+ years and he said that my oil leak was coming from the harmonic balancer/oil pump area and that there is a kit available with new o-rings and gaskets and other junk. He said that he has seen several trucks with the same problem and the very fact that they made a kit for it leads him to the same conclusion. Has anyone else ever used or even seen this kit available? Right now i just hit the 200,000 mark and the only thing wrong with my truck is the freakin oil leak. Somebody help!
  • I had the same problem that very slowly got worse over a few years. Cold the engine would run fine, warm it would idle slower, make a coughing sound and shake, pumping the brakes would make it almost die sometimes. After adjusting the valves the problem seems to have completely gone away. Hope this helps.

    Had my 1988 4WD Toyota DX brake lines replaced as well as the thermostat. Something he noticed but I knew also was the engine kind of lags on acceleration with a warm engine at times. The truck only has 70,000 miles on it and is pretty much locally driven which would probably explain some of that. (Had a company work truck for many years which accounts for the low mileage)

    He suggested putting in some "Toyota" fuel injector cleaner to kind of clean things out a little. Is he pulling my leg by promoting the use of the Toyota brand or will any good fuel injector cleaner work?
  • :confuse: :cry: I've got a 1994 Toyota Pickup; I did an oilchange onit, but upon taking off the oil filter, there was no oil in the oil filter...., I repalced the filter with the new one, then filled the motor with 5 quarts of oil and then the dipstick did not read anything.... I'm thinking maybe my oil pump has gone bad, but I'm not sure; any ideas? And if it is the oil pump where is it and ow do I repalce it???? Please help!?!
  • Yeah, man. That sounds a little fishy. I've always put in Berryman's B-12 carburetor/injector cleaner in my truck and it keeps it running just fine. You can find it at any parts store and it's $3.50 a can. Every time I change my oil I put in one can to one full tank of gas. I'd try that before getting the fancy dealership additive.
  • My 94 toyota has some issues and I need some help. So I am gonna start from the beginning:

    For the past couple of weeks, I'd be driving down the road and the "yota" would kick forward almost as if the engine has shut off (but it didn't) and then it would buck a couple of times. Then it would drive fine. It kept doing this, progressively getting worse. Finally it started idling really rough when i would start it, and it would kick out black smoke, and eventually die. When I would try to start it back up, it wouldn't start, it just kept cranking. So to try to fix this problem, I replaced the fuel filter (which is a ROYAL PAIN IN THE [non-permissible content removed]!!!), air filter & spark plugs. It already has a new starter. I also had a slight radiator leak so I drained the radiator and added antifreeze & stop leak. The truck, after a couple of hiccups, ran like a champ.

    Then after about a week or so, I noticed it starting to run Hot. Not overheat but to the point I would turn on my heater to try and keep it a little cooler. It appears my water pump is now leaking, so I am going to replace it & my thermostat. I think this should fix my heating issue. But after warming up, the yota kinda hiccups and shuts off. And again, it just cranks not start. After about five-ten minutes it will, but what the f#@k? My check engine light comes on periodically and shuts off after a little bit. Is this connected to the heating issue? What could cause these problems? SOMEONE PLEASE HELP ME!!!!!!!!!!!!!!!
  • Well, man, I don't know if it's all related, but I do know that Autozone's pretty much nationwide will run the codes from your computer for free. That'll at least tell you why the check engine light is comming on.
  • Thanks for the reply, I live right around the corner from autozone. I'll take it over there and see what they say.

    Just FYI today I changed my waterpump, thermostat, both belts, and did a completely flushed my radiator. The truck isn't leaking anymore, and it's not running hot. But it'll run fine for a while, then choke up and die. I am starting to think it's a vacuum leak or something. F#$@ING SMOG SH#%!!
  • No problem, and BTW while you're at autozone ask 'em for a can of Berryman's B-12. It's the best fuel system cleaner I've found. It's worth a shot and it's only $3.50 a can.
  • Its sounds ike you have the overheating part figured out. The hiccuping and the slight coolant leak sounds like a head gasket leak. If the air leaks into the cylinder, it will run extremely lean and cause a very rough idle. If it is a 4-cylinder, this will cause sever for awhile and improve the driveabiltiy like you reported.

    Perform a compression check on the motor to verify this diagnosis.
  • Unfortunately, what I have to say is not good news.

    Your problem is exactly the same as my problem with my 92 3.0L V-6. I also had codes 14, 25, and 26. I replaced the Os sensor, cap and rotor, and refitt all of the electrical wires. Eventually, I got it down to just code 25, but the engine started idling roughly. It would still run fine at speed with a very slight loss in power.

    I went out and got a compression tester, and checked the engine today. The number 4 cylinder has almost no compression, anbd I noticed a slight oil leak above the plug hole. Diagnosis: a leaking head gasket (again). Last time it was between adjacent cylinders (4 and 6), which had a more noticeable effect at idle.

    Perform a compression test on your engine, especially cylinders 4 and 6 since they are the ones that usually go bad. A blown gasket will be readily apparent with a pressure of well below 100psi. These engines had a recall for a badly designed head gasket, which was blowing frequently. Toyota replaced these gaskets with a supposedly redesigned gasket. I think they just installed a new one of the same design. Either that or the problem is with the head design rather than the gasket.

    Other symptoms would be a coolant or oil leak if the gasket leak is bad, and poor gas mileaage compared to past mileage.

    P.S. The raw gas being dumped by a leaking cyclinder could have comtaminated your new O2 sensor.
  • 4 cly, auto. Starts and idles fine. When driven it dies and can be driven if you constantly baby the throttle. If you accelerate it in neutral, it dies or sometimes will rev up if you mess with it long enough. Check engine light is not on.

    Put on a new fuel pump and filter. Plugs, wires, cap and rotor. No change. Any help would be appreciated.
  • I'm pretty sure you need to check your Idle Air Control valve (IAC) that's a common problem with automatics of many makes.
  • It runs fine at idle. It dies when you try to drive it. I thought the IAC only adjusted the idle speed. Is that correct?

    I didn't see a MAFS, just a big box with a flap. I assume it does the same thing. I'll have to figure out how to check it.

    Thanks
