What is your coolant mix ratio?

Double check your burp by lifting the font of the car, or parking it on a hill nose up, a curb would be plenty high.

Crushed hose? if they are not on straight it could have gotten kinked.

Whats outside temperature? Does the heat work good? Like if you sat there long enough you'd literally cook good?

Suppose the tensioner is bad? Did you get a new one or re-use yours? How did you compress it?

just a w.a.g.

Re-used the tensioner....compressed it in my vice, 1/2 turn every minute till compressed, put pin in it...and it appeared to expand properly. Can I remover the belts, balancer, and timing covers and run the motor with the TB on to verify pump operation without any damage?

:lol: Car food.

Head gasket. My other option was a plugged bypass system, but it's too hot there for that to matter.

If you have compressed air (~100 psi) you can hook it to each cylinder and watch the radiator overflow when the bubbles start coming out. I've done that a few times, most recently on my wagon.

nice idea....I'll give that a shot too...never hurts to double check.....If I have to do the gaskets, is there a good procedure write up anywhere besides a Chilton manual?...

Yep, throw away the Chilton manual.
:lol: Just kidding they are helpful, but wouldn't be my last stop for information. The FSM is so easily available for these cars, makes no sense to use anything else.
http://www.main.expe...u_manual_scans/

head gaskets on the Ej22 CAN be done with the engine in the car, but it's a tight fit getting the heads in and out because the bolts can;t slide all the way out of the block. Pull the engine out if you can, makes it easier to work on and clean the block. Have the heads milled flat.
Autozone carries Felpro head gaskets for $19.99 each. Cheapest price of anywhere that I've seen, and the Felpro is THE EXACT SAME gasket that you would get at a dealer. Even has the FHI swish logo stamped in it. Less than half the price.
You don't need new head bolts but the old ones can generally benefit from being run through a die/ wire brushed to get any crud out of the threads. If you have a tap that's the right size chase the threads in the block as well. Dunk the bolts in fresh oil when reassembling.
Follow the Torque spec for the head bolts in the FSM. Ask questions if you need to.

Symptoms are usually going to include pushing coolant into the overflow bottle when it overheats. Often overflowing the bottle.

It's generally not that difficult to bleed the air from these. One of two things is happening - bad thermostat or bad head gaskets.
