hi all,just joined,and bought a 26 freeman with a 4107 diesel engine,first of all ive got that dreaded grey oil in the sump,i havnt done much investigating as of yet,but hav an idea it will cost me if my worst fears are realised,which is burst liner,.but before we go down that road the jabsco water pump is leaking alot of water into the bilge,and i am going to replace this asap,and i was wondering would this be another way which the water could enter the engine and mix with the oil? thank you all in advance
