rings/rod and crank bearings
Where can i buy the rings/rod and crank bearings???
How hard of a job is this?
Does it need to be done by professionel shop.

this a precautionary rebuild?? or you low on compression or have blow-by? failing leakdown?
bearings are easy... cleanliness is next to godliness upon assembly.
your cross hatch wiped out? bores measure up good?

105 hour rebuild, precautionary only.
Just thought might be good idea while i got engine out of ski. ????
I am just not sure if i can attempt this build (bottom build)or if I need to look for help.

Ive looked at OEM parts list and dont think it is something i should dive into.
Looks like would be better to have someone else do the bottom end work work, or not even atempt it.
Just worried about 105 hours on engine and then more rpms with higher boost and then having issues cause the bottom end cant handle it.
OHH this is gettting confusing.
All i want is fast ski at 8,500 with no issues.

I would not worry about 105 hours. My yellow 04 has 120 hours and runs strong as heck. NO leak issue's either. I wouldn't do it unless you are careless with maintance and you ski is abussed.
These motors are very strong when properly cared for.

100 hours is nothing for these engines. I wouldn't sweat it one bit.

After this weekend I'm freaked out because PBJ blew out his rings on #1..(I mean #3), I got the same amount of hours on my boat/16# charger. I was told with 16#'s of boost and a heavy thumb that these motors a really only good for 50 hours or so I can't afford those issues..Pitching back to 8500 boys.. Can this be true?

Alex he is running the 8800 ECU too... That might have contributed to it.

I have 90 hours on my ski. 80 hours are stage 3. 30 hours are 2rude.
80 hours are WOT.
My ski still starts but, preliminary check of the plugs says I lost #3 cilinder.
It blew the dip stick out 6 inches.... I had oil everywhere!

Skoepp, you can do this. It's not complicated or difficult. Get the crank polished by a machine shop and then go by the manual. You will install the crank bearings with plasti-gage (I would think) to check torque values and clearance. Take the bearing caps off to measure the plasti-gage and then reassemble. It's not rocket science and this is the perfect chance for you to learn. Just follow the manual and ask for help when needed. 105 hours is not alot of time but like you said, it's already out and what have you got to lose. We already know you're a talented mechanic. Just believe in yourself.
