Fellas,
We have a knock....
here is a link to the video....hopefully this one will work better than before: Try copying and pasting if a clickable link doesnt show up.

My dad took the head off and found this on the #1 cylinder.

We always felt like we had a knock, but thought it was just ignition knock. So we adjusted the timing at 3/4 throttle and got most of that, if not all of that out. Then I moved onto the carb to try and tune it in at 3/4 speed. Thats when the knocking started REALLY REALLY BAD like in the video.
So we pulled the engine and are looking into to having it machined and re-sleeved. Has anyone ever had to do this to a 109 or similar engine? Just curious what to look for. If we bore it out, do we need to bore out all cylinders or just the one? Any advice is appreciated.

You won't know about the cylinders until it is disassembled and measured. I would suspect rod bearing problems, probably Babbitt bearings, crank would have to be ground and bearings re poured. |

I don�t see why just that one cylinder couldn�t be sleeved. Maybe you will be lucky and it is just that one wrist pin that is bad and making all that noise. It sure did a job on that cylinder.
(I have a Stover. CT2 stationary engine with similar damage, but on that engine there is just a set screw that holds the wrist pin in place and keeps it from scoring the cylinder (or not if that set screw comes loose.) |

We took the engine to a machine shop here in town and he has the engine torn apart. Sounds like it was not rebuilt very well by the previous owner. My fault for trusting a 30 year old rebuild.
Crank is shot, beyond repair. Machine shop thinks that is what cause a wrist pin to break/come off and scratch the piston wall.
Currently waiting on a price for him to machine everything and rebuild. Its a one man shop so might take some time.
I have found a few online sources for part for the block using the cross reference of a Jeep Willys 6-226 engine, but I cant find a crank. Would anyone know where I could find a price for a crank? |

I would check out places that service and rebuild older forklifts. I believe that Continental engine was used in lots of them. It shouldn't be too tough |

sorry I havent posted in awhile about this. We took the engine to the rebuild shop in December. He gave us a quote of $4500 to completely rebuild it. We decided to go ahead with it. It was a hard pill to swallow, but the right call as I will eventually be taking my wife and kids out on the boat with me. No sense in risking it.
We gave the go ahead in February and should get it back in about a week or two. Looking forward to getting it back, painting it up and reinstalling. |

Did you get a report from the machine shop about what was found that was causing the knock?? |

bearings and crank were shot. That caused a wrist pin to malfunction in the #1 cylinder. That in turn sent the piston into the wall of the cylinder...she has been resleeved and completely overhauled from bottom to top. |
