Steve- got to looking at the lines and the o-rings. Found one that was seeping, so replace the entire lot, lines with new rings on them. That is some kind of fun working under the intake manifold. BTW, one of the lines has been subbed to a banjo bolt termination on the injection pump.
Dr.Diesel- lost on the 50/50 with the shut-off valve. New one fixed the problem.
I still kind of find it odd that I managed to have both these leaks at the same time, but I must be lucky like that. Put a couple of hundred miles on this weekend and not a drip.
Thanks to you all
