The owner stated he took very good care of the motor ,not until the problems came to light did he say the guy who passed away put the motor together . My friend who knows him said the guy was a good guy. I blame myself for letting this happen, because the guy said some things after i bought it that now make me wonder (i just had to vent a little). The only thing i don't have to repair or replace is the camshaft,push rods,rocker arms, belt drive. I LEARNED A VALUEABLE LESSON. Thanks for letting me tell my story guys .
