Re: T-98 vent location? leaking fluid...
On the T98, the vent is a small flapper valve on the back left corner, on the same level as the cover bolts. Since this area is prone to getting highly mud-caked, its venting qualities don't last too long.
Simple quick fix: the flapper valve is just pressed in, not screwed... therefore, it should be possible to coax it out by prying, then clean it out and replace it.
Permanent fix: On my T98, I already had the cover off while rebuilding, so this was a little more feasible. I popped out the flapper valve, threaded its hole, and then plugged it with a set screw. Then, on the rear center, drilled and tapped a hole for an air hose nipple. Then, run a hose from the new attatchment to some point high enough to keep water out.
