What do you think of the "redline a day keeps the mechanic away theory"
 

The statement in this article about how raced engines don't have many problems got me thinking about this urban myth, or is it true? I really trust mechanics that have worked on a lot of engines (obviously these guys have) so it does carry some weight with me. What do you guys think?

I musta missed something cuz I didn't see that in the article. By the way, it does have good explanation of intermediate shaft failures. :confused:

Before capacitive discharge engines it was very easy to foul plugs in city driving. Mechanics sometimes did an "Italian tuneup." A few miles at or near redline in a lower gear would often burn the carbon off the fouled plugs.

Always two camps on this arguement with strong beliefs from each.

There is little real evidence to support either side.

Race engines are very different and not a good comparison. They're built to much looser tolerances, generally have much lighter reciprocating gear, and are designed to run at higher revs for long periods. They also spend much less time idling, or stop&go, so oil pressures and flow is generally higher /hr. run. Coolant too. Maybe more importantly, they generally are in better tune, receive greater and more regular maintenance attention than the average street car engine.

It all pretty much boils down to what you believe and how you want to drive your car. They all pretty much break eventually no matter what.
