More like a major set back. I suggest you re-build it your self. Can be done by a first timer in a few days. Since you won't have much cleaning to do and can re-use most of the apex seals, it will cost only a few hundred bucks in gaskets, supplies, tools and a single replacement seal. If you want, you can ship your new turbo to me for save keeping (heck, you're only going to destroy it too). :-) Dave Leonard Well, they say a picture is worth 1000 words. In this case the picture is worth about 1000 dollars. :( The compression tester prints a tape showing the compression pulses. On rotor 2 it looks fine. 3 peaks for every cycle. On rotor 1 there's one peak, one tiny blip, then nothing. I took off the exhaust manifold and, sure enough, two of the seals are shiny and spring back about 1/16 inch when you press them (hard). The other seal is intact, but not shiny and only springs back maybe 1/32 when pushed. It IS moving, so it's not a stuck seal - sounds like the side seals are gone. We'll know more when the Mazda guy gets the engine comes apart......
