Welcome to Justanswer ! my name is Gary and i will do my best to assist you with this problem
when you say water in the cylinder do you mean the engine coolant correct ?
and im assuming the engine coolant is low ?
ye coolant has got in some how level is low in rad
ok those injector sleeves can allow coolant or water to get into the cylinder and into the oil in the engine and mix
the best thing to do is have the sleeved check for them leaking if one is have the sleeves and sleeve seals changed if it still does this there is more than likely a cracked cylinder head and or a bad head gasket
those are the only 2 issues that will cause coolant to get into a cylinder and mix with the engines oil
the head gasket was only put on in january and the cylinder was on a replacement engine from isuzu with only 24000 miles had to take off head to replace heater plugs
ok then have the coolant system pressure tested and see if its leaking from the sleeves when pressure tested
if it is replace the sleeves and seals
if its not leaking from the sleeves then there is a head failure or head gasket failure
there is no other way coolant will fill a cylinder up
