1952 Alvis TA21

Well, the engine on the Alvis is now stripped down to its component parts.  It is extremely poor and we suspect that someone has used modern-type oil in this vintage engine.  It is so important to use the correct oil - all the moving parts in this engine have deep scores caused by carbon embedding itself into the soft bearing material and wearing away at the hard metal surfaces.

The waterways were also totally choked up with corrosion and debris so that the engine had been running quite hot.
