    Lost Crank Bearing on my 1300

    Frequent reader, infrequent poster (I think that will change)
    My '03 1300 shot craps this weekend. Engine locked up.
    After dissasembly found signs of water in area of (1) of the powervalves.One of the crank bearings disintegrated.
    A brief history: pre-mix (Amsoil Dominator 40:1) , dual cooling,
    D-plate, Jet-works + basically Riva stage 2. Consistently runs (ran)
    71+. Engine has 390 hours. Had lean seize at 160 hours due to faulty Riva EFI controller. Crank had been trued & welded.
    Take a look at attached pictures and please tell me what you think.
    I have a several question I need help with please:
    (1) Where is most likely source of water (it was not water injestion thru intake)
    (2) Can a trued & welded crank be pressed back apart & fixed, or do I need new crank. If so where do I get one. OEM is $900
    (3) What do you think of how the pistons & head look

    Lots more questions coming with another rebuild ahead of me

    I added a picture of the reed cage. That's 400 hours on stock reeds and they are in really great shape

    Riva won't touch T & W cranked.
    Pro-tec could rework it, but recommneds new crank (1000$ for T & W OEM)
    Crankworks will R & R all bearings for 1/2 price of new crank

    Can somebody vouch for Crankworks??
    Not sure which way to go

    Look at the area at the 10:00 position where the bolt goes through the cylinder. The black area looks to be a start of a blown head gasket.

    I would also check with Rad Performance on your crank.

    Head gasket is a possibility 4 sure. Is the gasket silver around the sealing ring ? Can we get pics of it ?

    Cyl base gaskets can leak. Cylinders can crack...check the exhaust ports. Plus you had a few hours on that baby too.

    Rad is awesome, if you can get in touch with them.

    Crankworks comes highly recommended by Hydrotoys.

    Bingo!
    I sure hope you have another outlet on the head, and have drilled the head gaskets out if you are running dual cooling on the 60T. Otherwise, you just found your water intrusion.
