    I'm coming here 5 years after you posted this. I don't know where you are now bro but you saved my bacon! I had shops throwing electronic parts at this thing even telling me my cats were clogged. I saw this video, took apart the front end of my engine, and found that crank sprocket had an entire belt tooth worth of wear in the keyway. My valve and ignition timing was probably going back and forth 10° or more. This is a mechanical problem that seems like an electrical problem to everyone who looks at it. Those shops were just going to keep taking my money and they would have never found this. Thanks a million for posting this I'd send you 50 bucks right now if I had your PayPal.

    This is the type of crap you find on a motor teardown, very VERY difficult to find in your situation (not tearing down). Really good stuff man, definition of not giving up. I've always felt when a job goes perfectly you learn nothing, this 3.4 sent you to school and you came out with a well deserved degree. ALSO I've got a 98 Tacoma with 345k and no idea when timing belt was changed last AND she seems to be lacking in the power department, will definitely be checking this when doin that job, something I had ZERO idea I should look at while I'm in there. Thanks big time for that, think I'll be checkin out more of your skills. I work on shit, I know how hard issues like that can be. This video is just awesome... and greatly appreciated.

      Absolutely!!! Computerization of automobiles is great, but no matter how "smart" the system is, it's always going to miss something that it wasn't programmed to observe. This is where you put the scan tool down and use your hands. My usual practice, when I buy a used vehicle from a seller who didn't keep good records, is to replace key components, fluids, and update records from that point forward. Peace of mind is better than being broken down away from home. Keep me posted on what you find.

    Nice catch! Most technicians would just continue to throw parts at the problem to only make them look like an idiot and pissing off the customer in the process to the point that they will never come back. I've been a dealership technician for over 2 decades and I always get stuck fixing my coworkers come backs after their 2nd failed attempt which happens more often than I care to admit. I guess that's part of being the shop foreman. At least the jobs pay well and I get to see the odd problems that most never get to see . Love to see videos like this, keep them coming.

    Whenever you/we do a timing belt replacement,
    Do so accordingly to the Toyota spec.
    I had mine done by a Toyota M/M after a reputable shop replaced the timing belt (only), later a phantom oil was found.
    The OE Toyota 5VZ 3.4L V6 kit that the Toyota M/M used contained the following:
    New Parts:
    1pcs Timing Belt 13568-69095/13568-YZZ03
    1pcs Idler Roller 13503-62040
    1pcs Tensioner Roller 13505-62070
    1pcs Front Crankshaft Seal 90311-40022
    2pcs Front Camshaft Seals 90311-38051
    1pcs Water Pump 16100-69398-83
    1pcs Hydraulic Tensioner 13540-62021
    1pcs Thermostat 90916-03075
    1pcs Air Conditioning Belt 99364-20870
    1pcs Alternator Belt 90080-91090
    1pcs Power Steering Belt 90080-91126/99364-21070
    By following the Toyota M/M spec and not just replacing the timing belt only, you/we will save $ & acquire a better working knowledge.
    Compatible Model:
    1996-2002 Toyota 4Runner
    This complete parts list was found on eBay and was the same as the parts list/repairs I needed to do to locate and remove the phantom oil leak,
    it would have also provided discovery of your diminished crankshaft pin/key that is/was causing you throttle sensor problems and would have saved you the unnecessary purchase of a new throttle body.

    This is helpful! What did you do to correct the bottom -- crank spline? How'd you get that spindle to ride where it needs to? I have the same engine, 3.4L V6 on my '97 Tacoma 4x4... just turned 290K and got my first ever 'check engine' on the dash. The symptoms were, it started strong as always, it idled ok, there was no hesitation in acceleration but when I got to speed and the load fell away the RPM fell off as if I pulled my foot off the pedal. I wasn't able to get a reading on it. Five different devices couldn't read it. Toyota couldn't read it. The truck had a stroke, I've got the brain out getting refurbed and I'll get it back in like five days. I have been racking my head trying to figure out what might have caused the power glitch -- because the check engine light came on at the precise moment that the power fell off with no load. You showed how that can happen. Now all I got to know is what did you do to fix it, did you video the job? Thanks, KCOD

    Sounds like throttle body nonsense is caused by timing confusion: need a screen to log crank timing signals vs. cam timing - this instability would show up, as the drive hub on the crank walks around it's [trashed] keyway. Is there a handheld that can do that? I have an OBD tool, but don't think it can catch data with millisecond accuracy [plus the screen is too small].

      That's exactly what happened, and lead me in the wrong direction originally.

As soon as I took the upper timing cover off, and hand cranked the engine, boom, delay in timing belt movement.

    When plugs and wires don't work I would go strait for the timing sometimes it will jump a tooth still run but not well. I can't imagine a throttle body going bad without visual damage. The TPS maybe but easy to check. Throttle body you just clean. Live and learn.

    Did this engine by any chance have a tick or a knock coming from it? I've had a strange sound (sounds like a knock) that seems to be coming from the timing cover area for about 5 years since I've bought the truck. I've taken it to several mechanics, including what is supposed to be the best Toyota specialists in the Houston area and they suggest I have the timing belt serviced. So, I had it changed but the noise continues, though it seems not as loud now. During acceleration there is what feels like a miss but there is never a code and so I'm wondering if this is my problem?

    • @MeccaEl
      @MeccaEl  4 роки тому

      Hey Robert.
      No, there was no ticking sounds on this engine. It almost sounds like you have a slightly bent valve, or a loose valve guide, or loose valve seat. Maybe have a compression and leak down test done, and see if those results match Factory expectations.

    !!HATS OFF TO YOU SIR!! that is a demonstration of good old-fashioned SKILL & TECHNIQUE. these things cannot be learned at any tech school nor buy an apprenticeship. they can only be learned through years and years of figuring, struggling, trial & error'ing, engineering, reverse engineering, researching, getting advice, being creative & LEARNING TO BE A CREATIVE TROUBLESHOOTER! which is the hardest part. even factory certified techs with straight A's lack the skill and technique to solve problems like these. and most of them will never learn these skills because of how the dealers operate their service departments. any way man excellent troubleshooting and congrats on victory over your 5RZ-FE nightmare!!!. P.S. I hope you're working for an outfit that understands how valuable you are as a tech and pays you well.. cuz if not man I suggest you look for employment elsewhere. I quit my job with the Ford dealer in my town I could not work for the same wage as the tech's straight out of school. I found a job with a private fleet service Company literally make three times what the Ford dealer pay me, the company I work for takes guys with skills like ours and puts them on the road as mobile technicians. I only have to go into the shop sometimes four parts and once a month for a safety meeting. you should look into it. I found out there's Fleet Service shops everywhere.

    This guy didn't even know if it was a 3.4 or 3.6 liter engine. Kind of hard to miss that, when it said 3400 on the timing belt cover. There are so many different reasons for sluggish throttle or hesitation; man you cost this customer a lot of money in diagnostics. I had sluggish throttle and hesitation, and when spark plugs, new coils, and plug wires didn't work, I replaced the MAF sensor with an aftermarket one and the problem was fixed. Cost me $37 for an aftermarket one on Amazon, so I bought a second one in case that one failed.

      I think one reason for the cog keyway and woodruff key becoming worn is the crankshaft pulley bolt not being torqued to spec. and it works loose.
      The spec is 217 ft/lbs for the first generation 3.4 v6 tacoma pulley bolt, I used a new bolt from Toyota that has thread locking compound pre-applied, if I were to re-use the old bolt I would use blue loc-tite on it, but it's a $10 part so I use a new one.
