Curious as to why am Oil cooler would be needed? I take it there's no way of flushing it if there's debris?

You can flush it, but results are uncertain. |

The service manager at my dealership is a friend of mine so I trusted his explanation.

Doesn't the pressure bypass valve allow oil flow to bypass the filter when the car is very cold at startup in the morning? In this case if the pump is already crumbling inside metal particles from a failed pump could get past the filter. For what it's worth, I would ask the service manager to show you the filter and have them cut it open or let you take it somewhere to do that. It may be too late, wouldn't surprise me if the dealer already disposed of it or withheld for GM. |

It's not just the oil pump itself. Running the engine on load with low oil pressure will almost inevitably cause some damage, I would want a compression/leakdown check. Furthermore I would never consider buying a used car with a reported oil pump failure. Kind of like buying a car with an accident on carfax

There's no need to get a Katech pump, that's just throwing away money and probably voiding your powertrain warranty. GM worked with Melling to revise the pump design and the issue has been resolved.

You can sell the Katech to someone who is doing significant mods. Last edited by SFV1LE; 04-16-2021 at 04:20 PM. |

As far as I can tell the "new design" isn't any stronger. I'm going to make a video at some point in the next week or 2 showing why these pumps fail. |
