    NIce pic of the issue:).

    Was there anything in the housing that could be seen as the cause of the gash :whistle:?

    Usually with a scar like that, it has a mechanical cause. Just trying to understand better;).

    Glad it is sorted though (y).

    From what he told me its a orod7ct defrct they're seeing alot of when theyre hitting 130k to 200k in mileage. I saw another one where the gas was on the lower part of the cylinder. Nothing maintenance wise could have caught it according to him.

    Do you have the old pump or if the mechanic is seeing this frequently, could you ask him to take a pic of another one when he gets it:whistle:?

    Where I work we use a lot of magnetically driven pumps and sometimes we’ve seen the containment shell cut by a swollen magnet:cool:.

    Thanks again for sharing (y).

    Got the part about the product defect with the OEM water pump at certain mileages.

    But the second part I was having a time with; which cylinder was that again?
