Looks like I bought a dead motorset! Sweet!

I can give a history if needed, but would recommend reading my post titled "I love getting suprised, but not sure like this.".

I know that your suppose to get the car up to operating temp before you do a compression test. That understood I figured it would still be a good idea. Here are my numbers.

dry 65, 95, 90, 110wet 75, 100, 110, 130

I thought the gauge might have been bad, so I got another one. Same results.

At this point it sounds like I have fried piston rings. I have read up on results from warm engines, and it does not sound like there is a huge difference. Anything I might be missing?

they all need rebuilt as far as im concerned, its a 20 year old engine.

sounds like busted ring land possibly, but strip it down to a shortblock and bring it somewhere for a rebuild.

Mine lost compression on #1 too, it is the same age and it was not a terrible thing. Rebuild the motor as you should have to begin with.

Your motor needs a rebuild. I'll say it again because it needs to be said loudly. YOUR MOTOR NEEDS A REBUILD! 89 was the last year the CA was under the hood of an S chassis, that is 20 friggin years of use, older than many of the buyers are. Even the most religiously maintained, one owner engine, "only driven to Sendai on sundays" is going to be loose and need a good overhaul. Your motor has been beat up, badly. I have lived in Japan for 15 years, I see how they drive and I see how they maintain their cars, they DON'T. Your engine has been bounced off the rev limiter sliding around corners for years until it lost compression or the owner threw it away to get an SR. Know that it has had infrequent oil chages and rusty water coursing through the jackets. It needs help, will you help it? Are you man enough to help it?

AIDA gentlemen

It takes brass balls to drive a CA
