Ok so in early spring my 470 overheated on me and got the head gasket. so i had the head reworked surfaced valve job and reinstalled with a factory mercruiser gasket. boat runs great not even offering to get up to 165 on temp. However now i am losing oil from my dipstick and i mean like check the oil put the boat in run for about an hour and it has pumped all the oil out of. What gives boat runs great as always plenty of power real smooth hold 40 -60 psi oil pressure in gear. my dipstick tube has threads on the end of it like the dipstick is supposed to screw down on it but my dipstick looks like just a common dipstick with nothing to screw down on the tube. anyway like i say boat is running fine other than losing oil. please help im at my witts end
