"if he says its not worth fixing then i believe him"

Not to be anal retentive but I'd love to know what he's basing that on.

I was told once that I had a blown engine (throwing oil everywhere - too much head pressure). It ended up that all it needed was a PCV & oil breather ($8 & 5 min labor). That was back in the good old days though when shade tree mechanics could actually fix their rigs. Engines are more complicated now so he may be justified - maybe I just think too much.
