I found my freaking leak finally!! If you recall I had been chasing a leak on a 230FT and had already replaced the o-ring on the remote oil cooler adapter and the crush washers. I finally douched the whole engine down in gunk, hosed it and wiped it by hand. When I started it back up I laid under the front of the engine with a powerful little beam spotlight. I finally saw the steady ooze pumping from the oil press sending unit.

Next question: what size deep well socket is it? My set goes to 19mm and its too small. I'm guessing 22 mm but I would like to get the correct one the first time out and not repeat trips to the parts store. Anybody know which size I need?

Thanks.
