Team MightyBoy

Im looking at getting back into the mightyboy scene and looked at one the other day. The guy said the motor had been rebuild but the guy put the wrong rings in? Is that possible? And would that cause it to smoke a little when it heats up? cheers

It is possible. Could simply be the right rings incorrectly installed ie. upside down or gaps in wrong place. There are differing ring designs (usually relating to position on piston) and materials ie. cast, chromium & others. More likely is the situation where the bore wasn't measured correctly & the wrong size rings were installed eg. STD rings installed where first oversize might have been appropriate.
I experienced similar symptoms with an engine that had not been run in correctly & the bores had glazed up.

Do not take my word for gospel - talk to an engine builder. I am not professionally qualified, life experience only.

thanks for that i will have to track the guy down that did the rebuild.
