Hello Friends,
When it comes to technical issues beyond my knowledge, I turn to you guys,
independent of the engine manufacturer. The engine I'm building is a
Lotus-Ford Twin Cam from a '65 Elan S2. Here's the story and the question;
Bore = 3.250"
First compression ring = 0.083" ring groove width, ring is designed for 0.078"
width.
Second compression ring = 0.079" ring groove width, which is within spec.
Oil ring = correct.
Lotus specifies that the groove width limit is 0.080" but that's for a new
engine. My question is whether 0.005" is a little too large for an engine
destined for mild street motoring (with a few moments of spirited driving
tossed in). Or am I going to have to source custom rings? :-o
Thanks in advance for any and all advice. Respond off-list if desired.
-rick
