So decided to give my new K100 a toothbrushing.
Found evidence of light oil leak at the top and bottom of the timing cover so decided to take everything apart. (still snow on the ground for a couple of months).
Here is what I found.
The fairings oil, coolant has to be drained.
The valve and crank covers need to come off.
Wow my bottom end is clean (what a relief).
Wicked close but not perfect.
The timing cover (1990 K 100rs 16v) does not have a solid gasket for the timing cover.
Makes sense as the valve and crank covers mate to the timing cover.
The cause of the leak is that the interface of the Cylinder Head and the Block are not a perfect fit as the gasket seal for the timing cover is liquid applied (3 bond) RTV and overtime and heat cycles that slight imperfection let the goo out.
So, while i'm this far........
