So, I've got an old Onan in my 64 Bobcat. It started knocking, and from what I was hearing, it was a deep knock, but wasn't real bad. I assumed it was a rod, so I pulled the engine and checked things over. There were no signs of any damage at all, and for an over 50 year old engine, the rod bearings looked great. While it was out, I found I had almost zero compression on one cylinder, and the valves were very burned. Luckily enough, I've got the tools to grind valves and seats, so I got that all fixed up, and assumed the knock was related to the valvetrain. Anyhow, the engine is back in and running better, but I still have that knock.
Reading around on the net, I've see some people refer to a camshaft bushing that can work itself out of place. Can anyone provide more info on this issue, and can it be ignored for a little while, or is there damage being done?
On the plus side, while searching around for parts, I see there is a place in WI that is offering NEW ONAN short blocks for $399+tax with free shipping. I already have purchased one, and put it on the shelf for safe keeping!
I found them on ebay, and there were multiple shaft sizes and such. Couldn't pass it up.
