coolant still disappearing ;(
After changing spark plugs/wires/coil pack and about 4 hoses in the intercooling system, all symptoms went away and my 02 Cooper S was running soo strong all day I was so sure it was fixed. oddly enough go to leave this morning, misfire came back along with check engine light and bone dry coolant overflow tank :/ aside from anything to do with a head, (I hope the engine block test I did was right coming back negative) what should I look for? the misfire is in cyl 1 and I don't know where the coolant is going, but it is making it into the radiator as far as I can tell. the fans seem to be kicking on way too often for short trips to the gas station/store etc so obviously its hotter than it should be under there

I remember i keep adding coolant before. I thought i had a leak on head gasket due to constant overheating.

i was thinking head gasket too maybe but I bought a test to test for carbon monoxide in the coolant and it came back negative and I was told that means no head gasket problem. Fingers crossed

my other dying question is if the coolant disappearing and the misfire are related or two seperate issues 😩 Because of all the warped and broken hoses, and my spark plugs/wires being garbage I was sure they were two seperate issues but after changing all of it and still having both problems I'm thinking they might be related

I just looked into that, i do see slightly different test like radiator pressure test, fuel pressure test.. which should I try in specific? I just went for a drive, had to fill with coolant the overflow was empty, I can definitely smell the coolant burning somewhere while I drive, definitely from the front not the exhaust. Got home and it was dry again. just a short 3 miles to the store and back. Had to pull over because the misfire wouldn't stop on my way home. at this point I don't think I'm gonna drive it till I find out why it's burning it I don't wana risk further damage 😩
