This is what happens when you don't change your oil! - Motorcycle-Journal Forums

One of the mechanics bought a broken generator from a guy, planning on rebuilding it. It's a 16hp Briggs and Stratton V-twin. The guy didn't know what was wrong with it, it just quit one day. So him and I took the motor off the generator, and pulled the crankcase cover off, and this is what we found.

Bottom of the crankcase, with the pieces of a connecting and main bearings just chilling.

Some pieces of the camshaft and gear, it snapped into 4 pieces, the other piece is still in the block.

The piston sleeve and piston with a chunk taken out of them. You can see the rest of the camshaft in the upper left corner.

The guy said he bought the generator used, and had checked the oil, but never changed it.

Make sure to always change your oil!!

Wow, that looks nasty. You sure that's from not changing the oil or just getting really low on oil? Surely atleast having oil at all wouldn't cause all this damage. Could be wrong though, I ain't no machanic. (That's me speaking Pennsylvanian)

Shea, no it had plenty of oil, it was just real gummed up.

Oh, I see. That's no good at all. How many miles do you think you would have to put on a bike before it would get to that?

Before it completely blew up? Quite a few. 90% of the cars that come into the dealership for oil changes are like 1000 miles or more past due. But it depends on how hard you run the bike too.
