    attn to GreenHulk, or anyone can help,,

    Hi Jerry,,,your mail box is full, so i post it in here.
    Need your help on my 2006 rxp (120hr),
    i was playing my ski today only 10 minutes from the shore and my ski start to acting wierd, it seems like cut the rpm 2-3 times, it was like the throttle is empty. and it slow like it stop, by the time i accelerate, the engine shutdown, without any error or alarm.
    after that, i see the milky oil in my exhaust come out on the sea.
    by the time i try to start, it only crank 2x and after that the stater motor free.( and it wont let me start) wait few minutes, it do the same thing 2x crank and stater motor free.

    my friend pull me back to the shore and when i open the seat, i notice my coolant is empty, and the milky oil (white greenish) dripping out of exhaust.
    i pull the dipstick oil and check it is normal color oil.
    i try to start on the trailler and it does the same thing, twice crank and the stator free.

    i check the pump, everything is clean. i double check dipstick oil, the engine oil color is normal and in the 3/4 position as always at 3/4.

    what could be wrong? please help.
    the engine wont start till now.

    thank you
    Dre.

    sounds like a blown head gasket and the biggest mistake here that you tried to crank it multiple times while you had your engine hydrolocked. Hopefully you didnt bent a rod, the starter has enough torque to slightly bend these rods.

    best thing to do when these engines are not running right is just best to shut it off and inspect them.

    to inspect the connecting rod you have to split the engine and remove it and inspect it, or let a mechanic take a look, some ppl say by checking the compression you can tell but compression test will never really be the same.

    the ski will run fine and you wont be able to tell the difference. until later on that bent rod will come back and stab you in the back.

    I would start by removing the head and taking a look at the cylinder walls pistons and valves.

    Dre, sorry I'm just seeing this.
    You need to inspect for a bent rod also.

    What kind of damage to the piston? Can you post a pic for us?

    Hi Jerry, thanks for your reply, after i open up, it is a big mess in the engine. piston #3 is crush, valve is bent, the cylinder head is done( valve housing), block is crack. very bad. i dont know if this is cause by blown head gasket or my ski overheat? im using RR thermostart 168. my ski is rxp 2006, 120hr.
    i need to PM you on the item list that i need to buy and need your advise as well.
    thx
    dre
