let me give you a worst case, it happened to me.....many years ago by my first wife.....
I was informed the tracker broke down a mile from home, well upon checking it I determined it was a blown head gasket, when I cranked it blew radiator hose, then repaired & took cap off to have a raidator like a geiser, it also had an exhaust leak & didnt hear my other problem, ok so time to do a top end. well fix it & get it running to hear it knocking. huh? what happened? then it was "oh it started doing that while driving a couple miles back" while it was overheated. humph! well I take it down road for a test drive & a couple miles from home the piston broke loose from the rod & went through the block. KABOOM! all because she didnt want to walk home she tried to drive it as far as she could instead of parking it & finding a ride or getting a TAXI.
my solution was a brand new engine from Advance Auto, & under 1 year after we broke up she gave her tracker away. & until recently I havent been around Trackers, & presently trying to find one.
so if was overheated bad enough you may hear wrist pin slap.
Later,
Randy
