rings

[JE 17]

I've documented my travails with this 02 S earlier. 

Bought as a non-runner project. Engine had oil intake plugged with debris from disintegrated chain guides. Replacement engine No. 1 flooded sump with coolant after installation. 

Replacement No. 2 seized.

So, I have a wealth of parts and at some point, one of them is going off to LN to transform into a 3.8, but in the meantime, summer beckons, and I'd like to drive it a little. 

My question: can I reassemble using old rings just for a short-term runner? I don't believe honing is possible or I would just re-ring. Is that correct?

If the rings are going back into the bore they came out of, so that the used rings match how oval the cylinder walls are, possibly; otherwise, you need to hone and re ring it with new rings.

Thanks, I thought they couldn't be honed. I have no aversion to new rings and would prefer them.

On second thought, I would suggest you contact LN about your idea of a short-term engine assembly, it may be more complicated than you thought.  You may also be correct about the honing due to the plated surface.

LN confirms no honing, but suggests reassembly if ovality is ok.

So my plan is putting a temporary engine in for the summer as the other is sent in for Nickies. I think a 3.8 in this car will be more than a blast!

There is a benefit, too, in learning assembly on a non-critical engine so when the "better" one is built, I may know what I'm doing!
