I am pleased to report that we have your engine and IRS rebuilds well underway. Unfortunately, your IRS is probably the worst we have ever seen in terms of condition. We enjoy a challenge, but this thing was really nasty!

The engine has obviously been serviced a number of times. The rod journals have already been ground .030" undersize, so we were fortunate to track down some .040" rod bearings in the UK. The water jackets behind the cylinder liners were completely blocked with rusty sludge so the block required some significant extra time in the chemical wash tank. We have already replaced all the liners and begun honing the cylinders to size.
