I have an 88 Blazer with 5.7l 350 that crapped out on me on the highway. Mechanic says he thinks bad bearing, the engine is bad and needs replacement. I have a transmission leak as well. Does it make sense to fix? I can find a reman for $2-3K installed. Should I put in a new one or sell it and buy something else? Any ideas on what would make it worth anything now? I am a complete newbie and pretty mechanically useless so any advice would be very welcome. I am halfway between Richmond and Charlottesville, VA if anyone would want to take a look at it.
