Hi Neal The boat was going out for the 4th time and fired up easy motor was starting to loosen up prop 1st time out was an Andy Brown prop 1457 and we had changed to a 1657 set the motor on a flow meter 50 % fuel motor was rich I phoned Mike Hallam for a price on parts I do not plan on fixing this motor I have had many nitro motors over the years and know what to expect. The video posted below my post by nightmare that motor was my 45 exr black head I should have kept it.
Thanks

Tim. from what I saw the rod split at the oil hole. no heat marks no blue marks anywhere. the rod came off the crank pin clean with out the bushing, I could see the bushing on the crank and it looked like new, everything in the engine was nice and shine.... it looked liked it never run!!!! its a shame that the manufactures don't stand behind there product because to me it looks like a defective rod :angry:
Gary take some pic from the parts and post here so all can see what a piece of **** that engine really is.

Guys,
Not to start a "Picco Bash", but it sure looks like the Picco rods of the past. I suppose Picco will continue to blame us "stupid Americans" who "use too much nitro."
They'll never change.........
Thanks. Brad.

h34r: Hardly believe piston fail from rare mistake cnc machine or lousy quality material ABC ( not compound metal) cause somewhere poor balance or too tight onto the sleeve

Allan, the sleeve and the piston are perfect... no discoloration, no pitting, both C clips in the wrist pin.. I think the engine was tight but I don't think it contributed to the rod giving in. I think the rod itself is defective.

can you show picture of sleeve? Reason you can't see on piston very thin hairline cracked so very rare poor compound aluimiun from melt not complete or drop to hit somewhere pistons in the box but wish underwarrenty before inspector clue on piston any cracked or tight P/sleeve so will replace it( no fire start to run) and keep your save neckAllan, the sleeve and the piston are perfect... no discoloration, no pitting, both C clips in the wrist pin..

Do you have any way to measure the crank pin to see if it is round ?
Just curious.

yes it does
sorry for quality of the vid as it was on my M/phone
look i love running boats and it is all to do with running the motors in and holding back from leaning them out and when you think you are done running the motor in then double what you have just done
all i can say is if they are run in right then you should not have a problem
keep the oil up..... heat cycle the piston and liner...... and when you think you are done........... run it in some more
thanks neal

Gary has a very good understanding of how to break in a nitro motor properly , he is not new to this.
If the crank pin has been ground properly and is round and if the clearance between the rod and crankpin was good then that leaves the rod itself to be the problem.
If the manufacturer is willing to sell a motor with the piston is so tight that it could lead to potential engine failure then they should also be prepaired replace the product when it fails.
I have had engines that were so tight I used a wrench to get them over the top and the engine never failed , but that was NovaRossi.
Gary has just lost a fair amount of money on an engine that he believed to be safe to run out of the box and it failed , Picco needs to step up and replace the engine and they also need to fix the problem before to many others waste their money.
Best of luck Gary

Thanks Tim I have been many years in the hobby and many engines not just boats helli and planes I run gas and nitro had a problem with a gas motor RCMK it was replaced you see they brought a new product out and there way of fixing the problem was to try and keep every body happy my motor was not the only one they replaced. I feel picco lover feels I am to blame for the failer.
