While doing the thermostat the throttle body was removed and there was probably 2-3mm thick build up of encrusted oil. I don't think there's a problem as the car has done 140,000 and probably never had it cleaned.
Anyway, the throttle body was easy to clean, EGR cleaner and pick off the large bits with a screwdriver, but if feels like the intake chamber is also lined with this.
What is the best way to clean this out? Is it an easy item to take off. I'm very much aware anything dislodged will go in to the engine.
I think it's worth doing for peace of mind and the engine is a lot smoother running after cleaning the throttle body.
