Hi everyone, Im a newbie to the site, from Toledo Ohio. Ive been a long time Toyota (and Chrysler) owner, and wanted to see if any of you have experienced this problem. Ive got an 88 Toyota 4x4 pickup, which has ran strong with little trouble for 204,000 miles, but in the last year has developed a rattle in the engine when cold. Im a Chrysler mechanic by trade, and have never had a reason to tear my 22re apart. I have changed the oil every 5,000 and adjusted the valves, etc, since new. Especially in the winter, when I take off out of the driveway and go to shift gears at higher RPMs, I get a loud rapping sound. It goes away after she gets warm, and it runs perfect, as always. Its came to the point I let it warm up for 25 minutes everyday before leaving. By opening the hood when cold, and revving the engine, I can hear it in the top end. I replaced the valve cover gasket this summer, took a quick look at the timing chain, and it looked good. I am considering a new engine for her next year, but if someone here has had this problem and its not too much of a fix, I will do it and get a few more thousand miles out of it. Thanks for your help.

I'd pull that valve cover off and look at the timing set again if the rattle seems to be at a certain RPM range. The later model 22r(e)'s are bad about breaking timing chain guides. IF the guide breaks then what you are hearing is the chain slapping the inside of the timing cover. If you let it go it can machine its way into a water chamber in the timing cover (big trouble). I had that exact problem in my 85 4runner. It made a rattling sound around 1800-2300 rpm. It was worse when it was cold. I descoverd that the chain guide on the right side of the engine was totally gone. I also discovered all of the pieces of the guide in the oil pan. Luckily it had not totally gone through. Email me for pictures.
The problem is that toyota went to an all plastic guide when when they went to a single row chain in 84-85?. They are junk but you just have to live with it or cough up the money to upgrade to a double row timing set along with the new cover and oil pump necessary to do so. With those kind of miles you're probably due for a new timing set.
Hope this helps.

Yeah i forgot you can get the metal-backed guides from LC. The reason i forgot is because i was going to buy them and realized they are $80. At the same time this is much less than buying all the other stuff to upgrade to a double row system.

your rokcer arm pads are prolly toasted. I just fixed my 22re's top end and the #3 and #4 exhaust r-arm pads were scored bad! They both had 3 flat spots where they rode on the camshaft, making a god awful ticking- rattling sound. i also had my cyl. head rebuilt too. now it runs whisper quiet!! check you rocker arm pads for uneven wear!
