Pretty much all signs are pointing towards a spun bearing. Knocking sound when revving, metallic mirroring in the oil, oil burning, and low oil level (possible cause and totally my fault, lesson learned :bash. From my research (Im not very mechanically inclined so bear with me), it seems that I need to either replace the short block or rebuild it. Im planning on keeping the power level stock so I assume just a rebuild will be the best option. My question : How much am I looking at as far as the short block rebuild goes, parts and labor? Im sure prices vary but a ballpark figure would be great. Any other suggestions? Maybe a place near Miami I can take it too? I know these guys specialize in mustangs, obviously :lol1: Mustang Specialties - Home If you need more info just let me know. Thanks guys.
