Car is actually my parents. Old BMW's is my thing.
Last year (before I started learning about cars) I was driving the car on a pretty long drive home from the shore. Long story short it overheated and got all sorts of messed up. Took it to the mechanic and he said the heads were gonna need to be resurfaced and need all new gaskets. Leading up to this happening the motor was running on like half power and getting alot of smoke discharge from the breather on the valve cover. Mechanic said what was happening was the seals were all deteriorating from not being run on leaded fuel.
Car will start and hold a rough idle but pretty much no power obviously.
So where do I start. Im used to straight 6's and 80's german engineering.
