well I got the news last night that the case on my 2002 WR426 is cracked and now I need to get a new one. over torqued the oil drain hole on the bottom of the engine and then the threads let loose and had to put a heli coil in it and when they expanded the drain hole the crack opened up. anybody have a good connection for a new one? I am not skilled enough to rebuild it myself but I would like to tear it down. do you think I could do any significant damage by tearing it down myself or should I just let the professionals do it? how much do you think it should cost to get a new case and a rebuild?
