ISX losing water into oil
I have a 2005 ISX and have been losing water. Oil samples came back this spring that is was in the oil. I changed inj. o-rings/seals and did not help. Thought head gskt, pulled head and no signs of leak in Head Gskt. Tested head and shop said inj. cups, cost about as much to fix as replace head so we replaced head with NEW RECON HEAD, it is the updated head cummins introduced. still using water, about 1 gallon per 2000 miles. Any ideas???
Is this a good question?
