Hi

[Z OH 6]

I think all 2017 and 2018 models are not if but when the oil pump fails.

[arpad_m]

Let me make one comment, not for OP who unfortunately got to the receiving end of this issue, but for everyone else who may stumble upon this thread later.

In light of the oil pump failure survey results below, one has to get the latest GM pump revision from 2019 at the very least, or even better, Katech's billet aftermarket pump that nobody has reported any issues with. See both options here.

OP send us pics of what the pump failure was if possible.
On mine the vanes in the pump broke off and littered the engine with metal shards.

I went to downshift its a M6 and I noticed the oil pressure went from the normal 38 to 40 psi up to like 65 - 70 it never does that so I slow down watch the oil pressure push in the clutch and it goes down to 38 and then keeps dropping slowly so I killed the car and towed it home. No noises no clicking or anything when I shut it down. Now my question is I have a lift and tools I was a GM tech back in the 90s but does anyone know a decent garage in Maine to do the work if I dont have the time? Maybe even NH? Do you think I should pull the motor and take it to somewhere like Jannety to check it all over and put a cam in it while its there LOL I shut it off very quick I am pretty confident I didnt run it low for very long at all, what am I looking at here.

Sorry this happened, but happy to hear you caught the symptoms early!

I think it is a good idea to send the car to Jannety for a cam and supporting mods while the engine is apart.

Oil pressure in the 30s isn't a failure yet. What temp was your oil at? Your pressure is also dependent on oil viscosity and temp. If you didn't see it below teens then I wouldn't say you have a bad pump yet. When they fail, you know it.

[race24x]

It was odd going down the highway the oil pressure was fine. I went to downshift and saw the oil pressure spike to about 70psi or so and that is what caught my eye. When I let it idle the oil pressure dropped down to 10 and was headed to 0 I think, but I brought it up to about 1500 and the oil pressure returned. I shut it off and towed it.

Good Morning and sorry for your trouble.

Jannetty Racing will appreciate your business.

We have done many oil pump replacements and yes we pull the engine every time, it is far cleaner and better results.

The timing covers and oil pan are glued on the engine with RTV which would be impossible to reseal with oil dripping out of the engine when working from underneath.

Certainly a good time to move in to a cam as well as there is a fair amount of Labor overlap vs the 2 jobs separate.

We just completed one last week and delivered last Sat.

Give us a call and we will go over what your goals and budget are for this project 203-753-7223

Thank you

Ted.

Sorry about the bad news.
I actually thought this issue was running out of steam.
Did you add it to the oil pump failure poll?
Good luck with the repair.

I did call Jannety this morning and I think I am going to pull the engine and take it to them. I have a lift and I was a GM tech years ago. The money I save pulling it myself would pay for the cam I want I could replace the oil pump but would rather have someone who has seen a million of these engines look at it and give me some assurance that I didnt hurt anything else. Just a bummer I am very sad. I left the car show with my brothers, one has a Mustang the other a Dodge Charger. Dont think I will ever hear the end of this.....

Look at the bright side, you'll demolish them again and again once your car is done, especially with a cam and maybe some ethanol

Who's going to retune for the cam?

[race24x]

I would use Jannety for that also. I used to use Josh Pearl for my 14, but he doesnt do it any more. Jannety helped me get my first tune which was an Email tune on my 14 that I added a supercharger. Josh finished it up when I put smaller pulley and E85

These pumps all seem to fail at the exact same point, 6:00 position in your photo where the metal is thinned at that semicircle for the pivot.
Despite subsequent "revisions" in the part number, I doubt they altered the metallurgy that goes into the piece that fails. That housing is breaking at its weakest point, probably due to cavitation.
A stronger casting by an aftermarket supplier is what I would go with.

My personal approach is to stick with 5w-30 for the long haul. As I have posted before, this pump we all have was originally designed to eek a few extra MPG out of the Chevy cruze, and GM subsequently plastered it across many engine platforms.

In a failed pump, it would be interesting to compare the leading and trailing surfaces of the vanes. That would be to see if there is pitting on the trailing side like you get with a boat propeller, a sure sign of cavitation.
