I took the cylinder off today - what a mess...
Makes for fun to see other peoples pictures or their bad engines as dismantling the own engine 

Water fully blocked

   

Oil everywhere

   

   

Interesting, that is still run not too bad...

The more oil burned the more rapidly oil blackens. Nevertheless that degree of blackness and tar is more characteristic of pre detergent oils. Are the oil rings totally plugged?
The top land has been rubbing but very common, esp as split skirt pisons soon devlop clearance. Can get a vague idea of taper from change of ring gap; nearer 1/2 then 1/3. When were angle cut rings last marketed?

Hi

That is a seriously dirty engine.  When I cleaned the crankcase on the RK I joked that we both had a serious paraffin bath together  Smile.  The back spray from a compressed air paraffin gun soaked me!

Your photos are great.  Please keep them coming as you start to rebuild.

Cheers
