[TR] Rings Not seating

[Roger Elliott]

Hi,

What is the most likely cause of rings not seating?

I rebuilt my Spitfire engine about 4,000 miles ago and still have 
excessive oil consumption.    I don't seem to be leaking oil, so my 
assumption is that it is getting past the rings.

I did check the gap on all of the rings during installation and they all 
were within tolerance - generally towards the tighter end.

I am planning on taking off the head and putting new rings on.

What steps should I take to try to make sure the new rings seat 
properly?  I am thinking I should run a hone down cylinders just to 
roughen up the walls a bit.


Thanks,
Roger  Elliott
