Hmm, piston rings heat up and expand, and can reseat themselves... Its weird how it does it on certain turns... Not sure what that could be. I think with wrecked piston rings or even valve seals it will run for the most part normally just the smoke. And of course it is also burning oil which I am sure would bring your hp down a bit lol.

Definitely would be one of the two IMO but for a better diagnoses I would definitely wait for a post from someone with more experience.

If it is one of the two the smoke will probably just keep getting worse but lets hope for the best.

Thats weird you say that because tonight I had to add more tranny fluid to the truck. There is no leaks still in the garage. And I have had someone tell me this also. How would I check it and if it was would there be results or what to look for?

To all the guys that Helped with the smoking problem, Thanks for all your replys. I changed the modulater valve or the vacuum diaphragm what mazda calls it. and I have cut the smoking down by at least 75-80%.

Now the smell is about the same and someone told me it smells like a bad cat? dont know.
