The timing chain on my 22RE broke a couple weeks ago. After inspecting with the valve cover off, I decided the inside of the valve cover looked good, and didn't need to be replaced. However, today I pulled the cover and found the bottom lip around the crank gear was broken-off. Should I put this project on hold and replace this timing cover, or can I still use this cover?

I'm sure Toyota put that lip there for a reason, bit I wanna get my truck back on the road...

Also, the chain didn't eat too much around the water pump.

Oriellys can get them for the newer blocks. Take yours in to match it up though. I forget how much they cost, but they dont have the older style blocks. Being as your is a 22RE you should be fine.

Did you have to loosen the head bolts to pull the cover? I'm trying to pull mine to inspect it and it's not coming off with all the front cover bolts + crank pulley + water pump removed.

No you don't have to. But there are a couple of bolts that come in from the back side, did you get those? You can see them in his second pic.

Ya, then there's the infamous hidden top bolt, it sits under a puddle of oil just inside the head.

I remembered teh hidden bolt from 20 years ago working on my 20R! I pulled the two on the water pipe, but I'm not sure I got the one just below it. Thanks!

I removed the head, but only because my valves were smashed to poo from the timing chain breaking.

I didn't make as much progress today as I woulda liked, so I might as well order another cover.... Thanks for the advise, everyone.
 
The oil pan should be an issue if he has the head off to check valves.

You're going to want to pull the oil pan off anyway because those missing pieces had to go somewhere. You better find them before they become an issues later.

If you try to install the chain in a; pan, chain, timing cover, head, camshaft order it's a royal pain because you are trying to pry the chain up to get around the cam sprocket, and you can not easily reach down and compress the tensioner.

The head and cam need to be on, then the chain, then the cover, then the pan.
 
I guess you are right, I have done a head gasket before without removing the timing cover. It was a PITA to compress the tensioner when putting the cam gear back on. It probably wasn't good on the chain either.

I changed the time chain on a 22RE a couple of years ago and found that same lip broken like your's is. I replaced everything except the timing cover since it wasn't the issue in the first place. I never had a problem with it. That being said, I would still recommend you replace the timing cover. I just had to get the truck back up again on a weekend.
