need an engine

I was riding down the back roads and heard a loud clacking noise, the noise got worse so turned for home. About 2 miles out from home the back wheel started getting shiney...yup the oil was coming out something furiously like...pulled over and the rest bleed out of the crank case.... Think I need a new engine.
But not really savvy about these things. Anyone got a spare engine for a 1986 Vulcan??? I really love my bike and would hate to have to get another.
Thanks.

I would do a full inspection to see if you maybe lost an oil bolt. It is possible you turned off the engine prior to perm. damage.

The good news for you engines from 86-2006 will work. The bad news is with any engine purchase, you don't know how well the engine was maintained.

Ok here is the hole and there was metal shavings in the oil, very fine metal shavings -didn't see any rubber pieces. My husband says it felt like the chain was very loose in the hole. We were thinking it was the clutch or shift leaver or something like that. We will have to tear it completely apart to find out. Unless you have some other suggestions for diagnosis. Thanks.

The left side of the front cylinder casing has the chamber where the upper and lower camshaft timing chains live. It must be the lower timing chain your husband can feel through that hole.

Yeah, if you are curious you can try to track down what went wrong, but the bottom line here is that you will indeed need a "new" engine. That is in no way repairable. I know from experience that it's painful when your baby dies. But the good news is that with some work it can be brought back to life. Good luck.

I just fixed one that the balancer gear bolt backed out. The damage was not that severe as yours. I used epoxy to seal the block. You are going to need another engine or at least the block halves.
