Metal Flake in Oil - Low Oil Pressure - Next Steps?

zisfor_nizmo

Bringing some closure to this thread. Over the course of the last 6 months the the Z got a replacement motor out of a 2012+ g37 with about 60k miles on it. The engine itself was pretty clean when we were taking it apart and it got new gallery gaskets, hardware, and a billet oil pump from boundary engineering. It also got Poly motor and trans mounts as well as ISR long tubes but not directly relevant, did new spark plugs as well.

The new engine has about 1.5k miles on it, oil analysis is being sent out to Blackstone to confirm everything is good, otherwise the motor feels to be healthier than the one we pulled out of it before failure.


Interesting bit for the folks who want to know what the hell went wrong: I took the old motor home and completely stripped it down, and I was baffled there was no visible damage anywhere. The bearings didn't look too bad and honestly the rest of the damn motor was clean. While cleaning out the valve train and removing the cams, I finally found some damage. Portions of the outer edge of the valve spring retainers were missing on more than one retainer. I'd say probably 5 or 6 of them had varying amounts of material missing. So she was real damn close to dropping a valve I'd say. I will post some pictures of this in the next post.

Currently car just had rear camber arms, toe bolt, alignment, and 285 square Indy 500 tires done. Looking to get tuned by Seb soon. To be done in the next few weekends: Pads, Rotors, Stainless lines, Brake fluid, Diff fluid and Trans fluid.
