Melling
I didn't see posted here but i believe Melling makes the oil pump in question. In case anyone was insterested. I also have a car built in 10/17 with 2800 miles but no problems yet.No major mods. Fingers crossed.

Looking like they figured something out for the 19 cars... Hopefully the number stays ZERO!

I wonder if oil weight has anything to do with this, I've been using 0 / 40 since first oil change. So far so good, I do know GM recommended 0/40. I'm no mechanic but I do know enough to get by and do understand 0/40 would be better at higher temps and under load/ Overheat issues have arisen on these cars. Potentially 0/40 is the bandaid?

For example, with a serious oil starvation event the most common engine failure occurs in the bearings resulting in damaged bearings, or even spun bearing(s) causing rod knock or a seizure breaking the rod. |

I just assumed most were catastrophically letting go due to a bad casting / machining or something along those lines & didn't consider being able to detect a premature problem. Gotta bunch buddies in the oil patch who deal turning in samples every week & would be willing to look into it if we could indeed see a culprit. |

I had an indication my pump was failing but didn’t realize it. Probably coincidentally, my dealer switched to 0W-40 for my second complimentary oil change (I did one in between with 5W-30) and my at hot at idle oil pressure dropped to 20PSI within about two weeks. One week later the pump failed.
I can’t confirm, but I suspect the drop in oil pressure was due to onset of the failure that degraded over the next 100 or so miles. I now use 5W-30 street and 15W-50 track and watch idle pressure closely. Last edited by Dixie ZL1; 09-10-2019 at 08:51 PM. |

Looks like Katech has a replacement pump. High flow better pressure. Be cool If it was a quick bolt on replacement and not have to take the engine apart. It would be worth it

You're most likely looking at the one for the dry sump Corvette.

I picked mine up February 16 so not sure of the build date. The first pump did not fail and had 180 passes down the track and 12600 miles. I built a new forged bottom end and installed a new pump, it failed after approx. 100 miles and 50-60 passes. Spun at least 2 mains and roasted the rod bearing. Don't know about the cam bearings/cam as I don't have it all apart and out of the car yet.
