Danger! Danger! Bill Robinson, (sorry, could'nt help it) The 185 thru 1125 Changfas have extraordinary oil pressure, above 320 PSI cold, in that line. This level of pressure can and has caused severe leaks of 2 types. Type 1 is finances, IE: wallet leaks, due to parts replacement and oil refill costs. Type 2 is more precious, and is the amount of time spent running or waiting for said replacement parts, as well as cleaning up all the oil sprayed out of the failed parts.
