Also believing in preventative maintenance, myself, I was curious your milage to have an idea of how bad mine might be. I understand each car is different and fuel types differ and environmental conditions also varying, but its good to have an idea of the buildup involved.
I see this is taking some time to do, are these "day" projects? If i put myself to it, can I get it out cleaned and back in in a day or even maybe a standard weekend?
What service manual are you using? Or are you just methodically disassembling and reassembling?
Good info, thanks for the pictures.
