Been noticing the smell of coolant (slightly) after long drives. Pop the hood, and the upper radiator hose has a half inch crack in the top. Oh well, no biggie. Car has been running rough as all hell lately, and I had accumulated it to bad piston rings (burning oil like a mofo, smoking at high rpm etc.). Replaced the radiator hose, and in the process, decided to check my spark plug wires. #1 cylinder's contact point at the dizzy end was bent to s**t.. went to straighten it out with pliers, and the thing just deteriorated. Replaced all spark plug wires, and the friggin car runs excellent now. No more running rough, and not smoking at high rpm. DAFUQ. I guess a bad contact/fouled plug wire can wreak havoc when it wants!
