Hi Guys,

I am helping out a friend's stock '89 TII...He thinks his car has a bad seal because he heard some ticking while racing some guy and now he fears that the engine may have detonated and took the seal. I am doubting it because his car idles fine and seems to rev okay, but it is just flat in power (just my opinion compared to my car; I have never driven his car before yesterday). Other than getting a compression test, what does the engine sound like w/

1. A bad Apex seal? Will there be idle problem or rev problems?
2. A bad corner seal? Will there be idle problem or rev problems?

Can any shop do a compression test? Or does it have to be a rotary shop (hard to find around here)?

Thanks in advance...

Jay

 

Any Mazda dealer will do a compression test for about $80.

 

Check the rear propeller on the turbo. Remember that the car uses the front rotor to start, so if it is blown in the rear it will still start. I blew all 3 apex seals on the rear, fucked the housing up, fucked the rear of the turbo and it woul still start. It could also be a bent apex seal. If I were him I would open the engine.
