[TR] Ring gaps

[Andrew Uprichard]

The manual for the TR3 says the ring gap should be 0.003 - 0.010.  But I
have new pistons and rings marked that the gap should be 0.003 - 0.004 per
inch diameter of the bore.  3 thou sounds awfully tight to me, but what do
others think?

 

On a related subject, a friend has an engine where the ring gap is 0.040.
How much of this could be made up by simply replacing the rings?  Or is
there a point at which the only solution is bigger pistons +/- rebore?
