My 94 toyota with the 22re has been making a rather loud ticking noise once it warms up. You cant hear it until it has come up to operating temperature. I have tried to adjust the valves and I know it isnt the timing chain, it was replaced 20,000 miles ago. If someone could help me out it would be very appreciated because it has me quite worried.

Sounds like Valve Train noise.

Did you adjust the valves with the engine warm-up to operating temperature...?

Could be worn rocker-arms and adjusters.

make sure you didnt overtighten your valve cover,should be finger tight + 1/4 to 1/2 a turn...like 9 inch pounds.start it up,back off the acorn nut a little,see if the noise goes away.

You did not put one of those cheap eBay timing kits in. They go bad fast. Can you make it go away under light loads. How's your oil pressure when it's ticking.

I adjusted the valves at operating temp to .008 and .012. I will have to try the valve cover being over tightened. The timing chain was replaced by the previous owner so im not exactly sure where the chain and tensioners came from but they are good, i looked at that the very first thing. It doesnt seem to go away no matter what i do after its up to operating temps. The oil pressure is where its suppose to be according to the sensor.

I think if I remember right the Cyldiner Head Cover(Valve Cover) nut torque:

-59 inch lbs

You said it makes the ticking noise once it warms up so I'm assuming it doesn't happen when it's cold. I think that can rule out the valve cover being over-tightened because the rockers would hit the cover regardless of the temperature. It would have to be some VERY tight tolerances between the rocker and cover to only happen when the engine is warm and the metal has expanded. And to duplicate the exact same noise both before and after the cover was removed to check the timing chain guides is very unlikely. Take a stethescope or long screwdriver to it and see if you can isolate where the ticking is coming from. I've heard of an exhaust leaking causing a 'ticking' noise, but it doesn't sound like that to me. Still, it's worth a check.

I took my stethescope to it and the sound is very prominent when i put it on the back of the valve cover on the intake side, so idk if that means that there is something wrong with the valve or the rocker arm on that side?

it is not.....

^-- Sure..?

Could have sworn... >_<

But yea usually snugging them by hand with a gentle touch will do .

If the valve lash was set properly, check the valve stems for pitting and the rocker shafts and rocker arm bushings for wear.

Is you're EGR making the racket. Maybe unplug it cap the vacuum line and see if it goes away.

I have a 94 22re with the same problem!! I've also taken a stethoscope and cannot pin point the sound, but is definitely coming from the back of the motor. As posted above, on my motor the sound only appears after the motor has warmed up. I've had this truck for over 7 years and it runs awesome, still runs really good. But just started making the ticking sound last year, and it only shows itself between 2000 & 2200 rpm. I was terrified it was the timing chain buy I had my mechanic look at it and he suggested it was the flange gasket on the exhaust. So after hearing that I replaced the exhaust manifold and it did minimize it just a bit...haven't got around to replacing the flange gasket yet

great-info-thanks

If I put a finger on the four nuts with the rubber bottoms (I think they're called gramonts) that are on the studs off the head that hold the valve cover down, I can feel my engine ticking/clicking. The ticking is more intense on different nuts and I've readjusted my valves based on which nut felt like the hardest hits were by it.

Weeks ago I put my 22re 87 4runner in 4-wheel drive and pulled a big fallen branch backwards for about 15 feet. I unfortunately had forgotten that I had the emergency brakes on and man did it make the brand new front brakes smell.

Well since then the engine made scary noises that 30-35% Lucus Oil in an oil change and 4 valve adjustments (done while the engine was cold but I used suggested smaller gaps to compensate for the engine not being at operating temperature) have improved, (or more like changed) the noise but what remains is when the car is warmed up there is a strong, poorly adjusted tappit clicking/hitting kind of sound and I can feel metal hitting metal when touching the four nuts that hold the valve cover down.

The gas mileage for the car has improved quite noticably, to the point where it's become fun to watch the gas gauge, and the power is roughly the same, though weaker now at idle (to point where the engine can lug when in gear at idle like it didn't before.)

The timing chain is tight and the plastic (unfortunately not metal) chain guides look fine. I have loosened the valve cover nuts and while the engine is running don't feel metal hitting metal when I put my hand on the valve cover (but as noted before do when I put my finger on the nuts over the four studs that come up from the head that hold the valve cover down.)

One of your great posts suggested finding where the noise is the loudest, from the top, the front or bottom. I need to do that.

If it is a valve smacking metal I am concerned that the valve could break, though from posts I get the impression other fellow owners have heard in their car(s) this noise for a very long time. I have to wonder if it's as loud as mine after the engine is warmed up.

Any other suggestions, words of solace? Thanks.
