QUOTE (Troy @ Apr 15 2004, 08:02 PM) Call me pedantic, but it's not exactly the best way to rev an engine. When there's no load you can actually glaze the bore, doing more harm than good, but you only really have to worry about this if the engine is fairly new and/or you do it for like 2-3 minutes at a time. I am being picky.
No, it won't glaze the bores. You need to idle your car for hours and hours and hours for this to happen! LOL.
Ask any truck/plant owner with a diesel engine that has glazed bores.... they'll tell you it came from idling for hours or overnight even.
