Last night I discovered a broken exhaust manifold bolt on the passenger
side of my 89 s-10 blazer 2.8 . I have noticed a slight use of water,
but none in the oil. Today, I was driving to the store and my temp
started rising. I pulled over, and to my surprise water was pouring out
of the manifold area where the broken bolt was.
I guess my question is...after 189000 mi. should I replace the whole
engine, or can I get away with just replacing the bad head with a used
one. I need to drive back and forth to school and to the store. thanks,
