What's in Vista, & why do you need a new bottom end?....or do you mean as-in engine?
My trusty ol Escalade (150k + miles) started having "low oil pressure, turn off engine IMMEDIATELY" warnings which have a lovely LOUD clanging chime, only 2 days before the event. Of course it turned out to be just a pressure sensor, but @ $ 539 r & r (dealership), I wasn't feeling justified in the expense to show up @ Chuckawalla just to watch!.....but I'm DEFINITELY attending the NARRA race @ INDE, Mar 23-25!
