Probably because they do not have $1,100.00 to spend on a new head, same reason most people rebuild engines instead of buying new ones.roscoFJ73 said:Why buy used 1HZ heads when they are only $1100 newfor OEM heads in Vic?
When I was speaking to engine rebuilders regarding my engine ,the reputable ones said get a new head.
Others were prepared to rebulid the head but without warrantee.
All the rebuilders I spoke to agreed the 1HZ head was the weak point but definately not a fault.
