I know 98% of the V8 ZJ's in '93 have had the engine replaced. Does anyone know what the failure was, and did the dealers replace the entire engine or just rebuild the one that failed?
Thanks[addsig]

i went onto alldata.com and did a search for this particular model. it looks like there were a LOT of service bulletins that were engine related. i'm not sure what a dealer would do, probably just tackle one thing at a time and not replace the whole thing... cost efficiency!
