Re: Oil leak - Cylinder Base

YepI That would be correct on the actual through bolt. I did the silk thread with thread locker or RTV in the thread.
I did both left and right ends to keep from leaking on either side. You will need to pull both 2 and 3 cylinders away from the case halves.
When you start wrapping the thread just keep wrapping it until it starts to fit snugly. Then do the other end and make them both fit snugly. I think I wrapped them at the outer ends but not outside the side of the case. You don't want to let the thread and locker hold the cylinder away from the case half! Add the thread locker to the thread and push the through bolt into place. It should be snug enough to keep it in place but not enough to keep it from going into place.
When you torque the bolt try to keep the ends fairly symmetrical.
My leak has been on the left front side of the case. There are 2 bolts that thread into the case half on the other side. I thought I might need to check out the cylinder base flat O ring but D and B Engines said the leak never happens with that base o ring. He said the 2 bolts are the culprit. I affirm that as I have seen oil coming out of the threads.
I finished remounting the cylinder and torquing the base nuts and installing the new push tube oil return tubes. I will most likely finish plumbing the rest this week while Honey Lamb is working. I get lonesome at the hanger so I came home to "entertain her"!
I will shout out loud if I can get this 0200 dry!
