Yes, good to have a lab...used a desktop SEM, Hitachi TM-1000 and an optical...but we're not metallurgical...I don't know what metal it is....I'm passing the material to a colleague at Uconn in material science to answer that and other questions free of charge. We do do gov't applied research...called BIR...Small Business Innovation Research...special govt set-asides for small biz alone.

Your car sounds amazing...500PSI on the cylinders?? Stunning...must have had a lot of power. Good to know that if well maintained, these engines can go the distance. Sounds like you had great luck rebuilding your injectors...the first couple of times I tried with Monark cores, the body leaked/weeped in the middle...I had to do a lot of lapping to fix that...wouldn't show up on the bench, only in a running car after a few miles.

Do you agree doing injectors and glow plugs every 100K or so? It seems to be that way. What oil make did you use? I've ben using Shell Rotunda with a bit of Liquid Moly.
