    I recently acquired an M2 valve cover (chrome) and even though it was NOS it did have minor pitting but with some chrome polish I was able to bring back its glory but I could not stop there eventually everything i owned that was metal and not painted got polished.

    The air-box can use a little more love but I need a more abrasive compound.

    But I was so happy to clean up the mazdaspeed exhaust because I plan to put it back on. There's a super small hole in one of the welds but I can fix it no problem.

    Here is what it looked like before i put it on the wire wheel:

    After:

    I hit the flanges really good with the wire wheel they had surface rust but that came off no problem. I want to send the mid-pipe out and get coated and painted most likely silver.

    And for a 20 year old exhaust this one is super clean practically no flaws considering its age and was on the car its whole life.

    Did someone say AutoX?

    The 6th of January i will be at Autox at my hometown track homestead speedway the have it in the go-kart track and that makes it very easy to see where you're going and you can do a ton of runs so very worth your buck. But I have to get ready brakes are number 1 these will be done this coming weekend I chose to go with Pitwork (Fronts) and ENDLESS (Rears) pads. Rotors will be DBA Drilled/Slotted (Fronts) and Brembo OEM (Rears) my SS lines are APP and the quality is ridiculous very well made and highly recommend them.

    I have needed to change the Trans and Diff fluid since I've received the car so for that I am going with Redline. Also I have read this is a problem with the earlier miatas but if I'm in gear and let off the gas it sounds like a grinding noise coming from under the car and it never ever makes a noise at any other time, only when I'm slowing down in gear. So if you know a fix for this please tell me.

    Finally I'm doing a lot of seal maintenance starting with the valve cover and shifter and i will be swapping in the A-Spec short shifter which I am really looking forward too using.

    Driveshaft U-joint, maybe?

    I have read countless forums with this same problem saying that my transmission maybe out of alignment with my PPF and I need to loosen the PPF bolts on the trans and lift the trans slightly and re-torque the PPF bolts to 80 Ft.Lbs. Also read this noise is very common with the NA6 Miatas.

    Here is a photo from my old CarDomain page of the Mazdaspeed vs the OEM unit on NA Miatas.

    Yes, the PPF needs aligned, quite often the diff is pointing nose down slightly so just lift diff nose a couple of mill and torque it up. It is very common and a super easy fix, obvs easier if you have a ramp and aren't doing it in the street ( but we all have to make do with what we got. ).

    It is relieving to hear its a common issue. As one of the forum members said "Sound like a bunch of ball bearings are spinning inside my transmission." I have stands so it shouldn't be too difficult.
