I had an UDP on my 1st Focus for 10k miles (automatic) and it didn't hurt anything (besides the a/c).

No... they don't. They can other engines... there is NO evidence that they adversely affect our engines.

Cant harm your engine. I put the crank pully on my car at 23k and now I have 96k and I never had to do eneything except change my belt(normal maintanence).

Its all good!
