This is a lose lose situation. On all internet forums there are conflicting opinions. 1 Person may want to do his own rebuild- members chime in even flaming him for not being willing to do the job himself. Then if he does it himself and something is wrong members flame away saying you shoulda paid a shop to do it right. 2 Person pays a shop to do everything because they want it done right. Engine has problems and members chime in saying you shoulda done it yourself and not paid some hacks to mess up your engine. I sure feel bad and angry for anyone who pays a supposed pro for pro results- but gets hack results and service after payment.
