No..non s/c. Did correctly startup procedure on water hose. Have air intake snorkel off and see water coming thru small hose at near oil cap assembly.. coolant level normal, compression good 160 psi.. no leakage on leak down..oil xhanged/ normal level. New plugs. Good spark. Does run off idle (dies) @ idle. No codes stored..guages are inop but try know good cluster..does seem to push more water thru as u accel/ gets hotter. Anyone see this?
