Running in a new engine question
Hey guys,
I tried searching for a running in a new engine thread and couldnt find one. Can you guys help direct me to one?
Thanks!
If there (by some remote chance) there isnt one, here's my thoughts:
I've heard the theory of running it in hard... here's a link:

VS the vast majority of automotive manufacturers who prefer you baby the engine eg:
http://www.volkswagen-environment.de...axis_21745.asp
I can understand the running it in hard theory - to try to achieve good valve closure.... but but, if for arguements sake if you take the extreme of getting 100% sealing then you'll get no oil on the sides of the pistons to lubricate the engine = more wear and less engine life (not that you'll get 100% sealing in reality). Sure you'll get minimal power loss from leakage but at the above mentioned expense of less lubrication.
On the other hand the manufacturers would rather an engine to last long rather than get extreme performance (for reliability issues) so I'm guessing that's why they want you to baby the engine....
BUT in the hard run in method wouldnt you run the risk of running in the seals against micro imperfections that could cause micro tears/shears in the ring? In that case then they'll always tend to leak once the piston 'bores' out the cylinder over time. Sure the manufacturing process is much better nowadays but it's not perfect right?
Opinions?
