Believe it or not, I bought an engine from Mazda. Delco Remy (GM) has the contract and has done all the Mazda factory rebuilds for probably 5 years now. My new engine showed up with TWO new rotor housings. I didn't rebuild mine because it was a high mileage motor and I thought the rotor housings and side housings were out of spec. Housings alone would have cost close to what I paid for the complete engine.
The original engine died because I changed radiators and thought Dex-Cool was a good choice for coolant. Two words describe that: STU
. I installed the new radiator, put in the Dex-Cool, and 8 months later my BRAND NEW radiator was leaking from a seam. I pulled the radiator and took it to the best radiator tech I knew where I was told, "Whatever you're using for coolant is devouring the radiator." When I told him Dex-Cool, he said the heater core would be next. I flushed the coolant and went back to plain green Prestone, and six months later, at 367,000+ miles, my original block lost a coolant seal. I've written articles about DEATH-Cool for both MazdaNews and RotaryNews.
That engine photo is from one of Dave Gibson's engine clinics. Someone from Mazda R&D (where SevenStock used to be held) showed up and filmed that clinic. Dave owns Speed Machine Performance (a Mazda shop in San Diego) and the ClubFC3S dot com website. This is the type of thing I'm looking for in the Mercedes-Benz community - clinics. Suspension, engine tuning, brakes, dyno days, track days, and things along this line. That, and we could use a performance magazine.
