With the thread of all the lovely engine bays i think its time i gave mine a bit of a clean to say the least... I keep the rest of the car mint but the closest the engine bay gets is the wing edges and around top of the lights leatherd off when its washed. When i take the audi engine cover off (its a 1.8t) theres a bit of well like dryed oily dirt pretty normal stuff really around all the coil packs ect. Whats the best way to clean the engine with out obviously damaging anything? Anyone got any ideas?
