A lot of the high mileage engines look like this with the valve cover off, see it all the time in Pittsburgh. He probably doesn’t check coolant and oil level often enough, BMW’s use coolant and oil, you have to stay on top of it, especially in hot climates. He probably ran the motor hot. High sulfer fuel might trash the o2 sensors, cats and injectors, heat and poor maintenance causes sludge. I’d sell that car. Pretty much every owner ive seen sells theirs once their warranty is up. I only know of a few people with older bmws out of warranty, they usualy race them and thats why. --- _[View the full topic](https://forums.speedlife.net/t/for-the-gto-guy-headed-to-mexico-or-anyone-else-who-likes-sludge-and-mexican-gas/196365)._
