So...before I start dismantling this thing, I was hoping for words of wisdom, or at least offerings as to what others might think is the root of this. The long story: My 2003 R53 has been acting a bit odd lately. I thought it was the fuel pump, as is seemed like the engine was acting as if it wanted more fuel (hard to start, "bogging down" on heavy peddle depression, and would pick up when the throttle was eased back on). So I replaced it. That seemed to work, at first...but then it started being real hard to start. I would need to "prime" it by turning on the key a few times and letting the fuel pump prime the line before starting it, even then, it would only, but nearly always, start on the third attempt. I also replaced the fuel filter, no change. It wasn't ideal, but I ignored the issue, as I only drive a little ways to work, and life has been hectic. I never pulled the CEL codes. I was just happy it got me to work. I was wondering about maybe a vacuum line, or something as the fuel tank never seemed to pressurize. Anyways...driving home last night it lost nearly all power. It didn't go into limp mode...just acted like it couldn't get fuel...would "bog" if I pressed to hard on the peddle, but would slowly get up to 3k for a shift to the next gear...so I made it home. I took the intake tubing off to see the throttle body, wondering if it was just worn out or something, and to look for fuel lines, and vacuum hoses. Well I tried to start the car, as it still acts like it wants to fire up, and will, just with a horrid rough idle...to see if I could notice anything...and I did. Coolant sputtered up from the throttle body. I shut it down and stuck a rag on a stick down the throttle body opening...it came back soaked in coolant. So...what do you think would be the most likely source of this coolant? I checked the oil and it didn't look like it had water in it. Coolant at that spot would mean it came through the supercharger? Isn't the water pump on the far side of the SC? Does it ever crack through? Could the weird lack of power be some leak in the SC due to such? I know that the only way to be sure, is to take it all apart and be sure, but I have found, that with these quirky little cars, there are often valuable insights to be learned from those who have dealt with the oddities of these MINI's. TL;DR: Coolant sputtered out of my throttle body. WTF? Thank you for any and all insight.
