I don't understand what you mean here.

Both cars have been in the garage as I've been busy with a home remodeling project. I expect to be working on the benz in about a months time. Before I begin however, I have decided to compression test the m102, and further diagnose/isolate the problem. If the problem turns out to be in the top-end, I MAY refresh the M102 and dump the CD, with the aim of sourcing a turbo diesel donor (or other interesting donor) in future.
