hatcity Posted February 14, 2010 Author Share Posted February 14, 2010 Thanks fjh for getting back so quick. i was hoping a light bead would do, but still have to dis-assemble to clean.O-ring was cheap and I do have a second on hand. Its just a PIA to take off oil fill and all for that but I guess thats a monday project.

hatcity Posted February 14, 2010 Author Share Posted February 14, 2010 Monday is now a working day. took care of it today, actually my son did. Wasn't that big a deal. Make sure it was clean and generous amount of silicone. will find out how it holds at the end of the day.BTW- the o-ring was split. much easier to fit in there on the workbench. again, thanks, Ed Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/12649-turbo-drain-leaking/#findComment-49678 Share on other sites More sharing options...
