I took the drives off to grease the u joints and now this year when I run it hard I think oil is comming out of the vents because the bildge has alot of oil in it and oil is dripping down from the vents, any suggestions?

I've had the same problem in the past. It's probably an accumulation of air in the drive. When you get it hot it pukes out.

Put a barbed tube fitting on the vent. Run a pipe out and into the bottom of a puke tank and into the barbed fitting. Mount the puke tank so that the top is level with the vent. I've found that a bicycle water bottle and cage works well for this. You'll need to punch a hole in the bottom of the bottle. Use a metal tire valve stem to mount in the bottom. It has a rubber seal so it won't leak. Remove the valve core and fit the vent hose you just installed onto it.

This way your drive can belch oil out and draw it back in when it cools down just as a cars overflow tank will.

You should first check to see if you're getting water into your drive. That, of coarse, is another problem.
