I had an SR20de engine that had problem starting. I repaced the engine and after 6 days the lower bearings went out; metal shavings in oil pan. I was replacing the head gasket on the first engine and had a head bolt snap in the hole; block down. Is it possible to take the crank assemby; including the pistons and put it is the second engine? I can't afford another engine although that is what I would like to do. Finances are really bad right now.
