Ok I have set timing to 5 btdc. Changed the plugs and oil. cleaned the throttle body and intake. Used Seafoam in the oil intake and gas. Have adjusted the valves 3 times first @7 and 11 cold, then 8 and 12 hot, and 7 and 11 hot. Timing chain and guides were all replaced about 10k miles ago have tightened and loosened the valve cover. Still sound like I am driving a diesel. I am at a lost here. I am ready to set this thing on fire. runs great though good power throughout the powercurve. Time for a hotdog and marshmellow roast to celebrate the yota passing

its valves.... my truck also sounds like crap.... my noise got worse when i tried to readjust and fix them.....

Just the nature of a 22re. What kind of oil are you running? Synthetics will make it clatter a bit more than usual. I just got used to my clicking.

Ok, I have the same issue. I know it is not a huge issue, but with all the metal in the truck, it echoes like a bad crank or something. My tercel 4x4 wagon was the same way.
Although, if you have done all that stuff, could it be something more serious?

fyi - im sure that you know that if you dont give your valves enough clearance you can burn them up.

Did you listen with a stethoscope? How about running thicker oil?

Same here-my mechanic(independent toyota expert) said that one of the valves got a little damaged because of the recent head crack(overheating) and it can't be adjusted properly -but that that's not a big thing.
He put some additive -ceramic power liquid(very expensive german stuff) and it helped with the valve and with the chain rattle at startup,oil pressure is also significantly higher.

I wouldnt worry too much, most 22re sound like that. While I am jelous of those quite ones, I know mine is extreamly powerful for what it is.
I have tried that STP oil additive and It helps, but it is still pretty cold here and I think it will be too thick on start ups.

Long term debate on whether or not this is "usual" on a 22re. Although it happens on a lot of them, it is likely because they all wind up with the same sort of mechanical issue.
I'd say, do the mechanic's stethoscope gag (long screwdriver or piece of pipe) and listen to each cylinder. Then one at a time, pull the spark plug wire on one cylinder and let the other 3 run as usual. Try pulling the wire to the one where you may have located the most noise first. If the sound stops dead when you pull a plug you probably have either a wrist pin or rod bearing issue both of which are relatively common on this engine.
The valve train can be noisy since you have metal cam followers on the cam, but a knocking noise like a diesel is something else. Make sure the valve cover isn't on too tight so the valve train isn't hitting the cover and check to see if the flame guard on the cover is getting in the way of something (notice any scoring marks on it or around it).
Just an opinion.

Thanks, will do.

I believe there are posts of the this problem which was due to the rocker adjustment screws wearing. I'm sure sombody can dig this post up quicker than me.
