| I poured a 50/50 mix of ethylene glycol into a fresh
batch of oil and it sank, but it leaves a decidedly green
film on the top. Is there some kind of dye mixed with
ethylene glycol that may be separating? I'll re-torque
the head and wait for the Blackstone report, but I think
I'll be pulling the head in the not to distant future. The
number one cylinder spark plug had a sheen to it, kind
of damp looking. That's probably where my problem
lies.
Thanks,
