And that is not wear... Neither is a loss of 500 RPM...
Well, you can define 'wear' any way you like...
Dar, you're playing with semantics to confuse the issue. Take the head off your car and look at the bores. Do they still have the cross hatching they had from new or are the bores polished? If polished, have you mistreated your engine?
Yesterday I finished running in the engine as per Dar's thread and last night I stripped the engine and spent some considerable time checking everything closely and taking some photos. There was one thing I found that caught me by surprise but I'm considering starting a new thread with two posts...the first for the rich running and the second for the "proper" running in.
