I honestly would have no idea where to start. I'm not very mechanically inclined. Like I said its not an issue as of now, but you can hear it and feel it when I stop at red lights and stuff. Everything still runs and drives great.

It seems pretty random from what I can tell in the video. I know it's not a diesel but this noise is very common on all newer diesel engines after an oil change. And it's nothing to worry about. It has something to do with the engine harmonics.

I have a duramax and it makes the same random "typewriter click" noise after an oil change.

If you google search "diesel typewriter click" you'll see what I'm talking about.

I know it probably doesn't help, but it seems too random to be a lifter or injector, unless the injector is slowing dieing.

My old '95 pickup's 3VZ engine had this sound. Sold it with 180k miles and zero operating issues.

My 2002 5VZ 4Runner has made this sound since I bought it. At 170k miles and 90k miles since I bought it, no issues.

I used a mechanic's stethoscope and the sound seemed to come from the power steering pump. Flushed the fluid this spring and it made no difference.

Sound disappears if I open the throttle. My guess is either something in the power steering pulley or maybe valve tick that just transmits to that area. Opening the throttle and getting some rpms might tighten something up a bit. Who knows.

My buddy's 4Runner (2001) has similar miles and doesn't make the sound at all.

No answers here, but I wouldn't sweat it unless it gets worse. [shrug]

i have a 2002 and i just did an oil change and now i have the same kinda tick. can't hear it in park but in drive or reverse i can hear it. it gets louder with the rpms and gets drowned out after 2000 rpms due to the motor. no power loss that i can tell not eating any kind of fluid from what I've been checking, just kinda annoying

So, had the same ticking sound as above, i also thought it was a valve train issue. As it turns out, today I blew a spark plug out, the same one I had to previously helicoil. The blown plug helicoil threads were still perfect, so my theory is that the combination of me not torqueing enough and a slight oil leak, the oil got in the threads and the plug worked itself out. That being said, the ticking noise must have been the sound of the plug firing further away from the cylinder as it kept back itself out. In the end, new helicoil, plug and ignition coil=engine running normal and no ticking noise.

I have a ticking noise too, and with a stethoscope I can pin point it to the #6 injector. However the rig runs perfect. Have run several bottles of techron throug it, no difference, so now just live with the noise....the "toyota tick". New plugs and wires did nothing for the noise. Compression is near perfect.

This spring I have to do timing belt and vc gaskets, so I might just go ahead and throw some rebuilt injectors in it while im at it. After all by then I should be at about 295k so they have seen some use. Last ones I did were from motorwest. Did them when I had a bad knock sensor. I bought their already done ones but now I have 6 spares right now and will send to them and have redone, they charge 20 per injector to test b4 adn after, clean , new seals and flow test print out. I think new seals are about half that per injector, so good deal I think. If you dont have spares or not time to send yours to them, then they do sell kits. They will also buy back your old ones when you are done swapping., well they used to anyway.

They also sell the fuel rail crush washers that you will need but not the fuel regulator o-ring.

no relationship to them, these were the guys mtbtim suggested in his video

20 per? pretty good. I bought some rebuilt injectors a while ago when i thought my #4 was going, but new plugs/plug wires fixed the misfire issue for me. My point of my story is i immediately thought the worst (valvetrain, etc) when it exposed itself and was so simple. only had it a year and a half, 270,000 on it!
