my engine is doing this weird noise like if it was restricted first i thought it was the cat that was clogged up so i took it out and it still does it, than i thought it was wit the full and it still does it, so i did a compression check and the fron one was ok, but i got no compression from the back at all, does that mean i blew an apex seal?

 

No compression means you blew an apex seal. Pray your rotor housing isn't fuxored. I'm in the same boat, another $800 down the drain..

 

have you tried the atf treatment, blew a engine last year,it was dead used the treatment and car strarted right up, go to www.mazspeed.com; under facts go to atf treatment, good luck
