got a wierd problem.

I worked on Hyster forklifts for several yrs. and they used GM engines and I did see that happen a few times. Check the bushings and shaft for wear. If it's real sloppy it'll let oil seep up through it and it really don't take much oil to make for a big mess. Only other reason I can think of is if the pcv valve isn't working properly or the breather is plugged up as mentioned above.
