Very low compression

Most shops will give the head a light soda blast to make it all smooth and like minded.

Are you serious? New one to me. I really can't imagine how that would serve any more purpose than cleaning off the rest of whatever carbon was still stuck to the valves so you think you're getting your money's worth.

BTW, you seen that they now make equipment for blasting with pulverized dry ice? No mess! Oh, and it's cold, so it's the safest thing to use on sheet metal!

Well in this neck of the woods they do and that's because the old napa parts store is the village machine chop main.

Well I've been procrastinating, but i am finally going to change out the piston rings. I read a post that said the oil pan can be dropped by just jacking up the engine a few inches http://www.toyota-supra.info/forums/...html#post32515.
Is there anything i should know about this method. Plus the head is already off so is it going to be a problem if i try to jack the engine from the motor mounts instead of the hooks on the head?
Also, are beck/arnley piston rings any good? I'm liking the $30 price tag from rockauto.com. Thanks in advance for any input.

input: Take the engine out. Theres no point of leaving it in if everything is already apart, theres hardly anything keepin it in there! You are going to have a much higher chance of damaging expencive internal parts if you do it from the bottom, and you will likely end up with more issues than you started with. You should probably at least get the block honed out equally if measurements come out into spec.

PAULMICIN: You have got to stop using autozone parts on this car.

Those parts are bandaids and you are setting yourself up for more work.
Parts like those you should be going toyota oem from the dealer. Unless you're punching and stamping the block.

And then aftermarket. AutoZone is the DEVIL.
