I'm pleased to report that the engine flush was good .
I did 3L oil and 3L kero and 3L diesel , fast idle for 20mins , drained the horrible mess .
Repeat with 5L oil and 3L kero , fast idle again for 20mins , drained slightly contaminated product , looking good
Straight diesel engine oil , fast idle another 20mins , drained , clean enough to say its all good .
Had a huge challenge getting the oil feed pipe to the rockers sealed at the block , I soldered it as usual but I can't have been holding my mouth right as I had to have several goes at it until it stopped weeping .
All good now
