You may be lucky and get away with a bit of 'glaze busting' and a set of new rings. This bore, (LR1) had a similar problem but engine now runs on full load without any oil burning issues.

Hi would you reuse the bearings that I have removed from the engine or do the photos show they has lost too much bearing material and are showing the copper coming through?

The copper 'is' the bearing material.

The white/silver layer is a running in material.

I would not personally use them. See link (third paragraph text & images).

Your call in this particular case.

Looks like new bearings required. Just need to measure the crank accurately to see if regrind is called for. I will continue trying to get the piston unseized to see if rebore and piston are also required.

Looking at your image of the con-rod shell I suspect the engine has been run with very dirty oil, it's also possible the crankshaft big end oil holes were not de-burred after the last regrind.

Default LD bearings

Hi, noticed this post whilst trolling through. I have some old stock bearings and a set of rings and perhaps an injector should you be in need. Would need to check though before. Mike
