i have coolant in my 2002 4.3 crankcase, i need opinion on what to do.fix leak, or just buy a engine? ill be doing work myself. what year engine will fit my blazer?

 

lower intake manifold gaskets

 

if its done gone milkshake on you,then unless you have the time and money to do a total teardown and check the bearings etc,then its just a big risk that youll have problems later. Id go a used engine route.

 

Yes coolant is killer for bearings. I'm thinking of tearing it down first, if its a intake gasket, I fix it, if it a head gasket, ill get a used engine. I figured by the time and money in changing head, or head gasket, I could buy another engine. If I go the engine route, what years is a direct bolt in? Is a 02 a one year engine?
