Months back, oil gauge pegged.
last few weeks, ran hot sometimes after slow city traffic. Not always consistent.
fully serviced about week ago thought fixed. Oil gauge running more normal but
running hot again, . Twice I added coolant. Mechanic found oil in coolant dipstick too high.. Mech checking for possiblespull heads, maybe oil pan. Could problem start with faliure of oil pressure sensor leaking coolant then spread?

Oil sending unit doesnt have coolant running through it, it's more likly a head gasket, intake manifold gasket or a warped/cracked head. Pressure and block test the engine/radiator.
