I was always told as a kid, and always at college and during my apprenticeship, that you do the first OC as soon as you get the car home.
Seems like a good rule & cheap insurance
I was taught the same thing over 45 yrs ago. I often read on this forum that engines are built cleaner than ever but obviously these people have never been through a machining facility, its messy, it smells of hot cutting oils and coolant, metal swarf flying all over the place. At the high production rates they machine engines at there is no way in hades they can clean each one spotlessly.
