Failed oil consumption test

WarmAndSCSI

I feel ya. I'll keep it more on-topic but I just find it amusing how many reports of this come from the Z community. People are probably just too nice to their new babies. Nothing wrong with that, but I wish I could redefine what "being nice" is for some people. Tough love is how I would describe it.

But on the real, I'd be demanding a whole new engine. There ARE some potential side effects of poor ring sealing on the engine as a whole.

Actually, I'm surprised somebody hasn't had a bearing failure during all of this. Fuel dilution in oil is pretty much the #1 killer of bearings. To that point, you could have some excessive wear in your valvetrain due to lack of oil protection and potential dropped oil pressure due to lower end wear.

Point these things out to your dealer tech or service manager. It's perfectly logical especially if the consumption has been on-going.

You can point these out to the service manager and such but they will most likely not change out the entire engine unless absolutely necessary. Nissan is going to approve the minimum amount of work required to fix the car. Until that motor is actualy pulled apart and checked to see if more damage has occured they will most likely stick to the original repair.

Well, to properly check every single camshaft/eccentric shaft journal, cap, etc for roundness and wear would take some serious labor. The OP should at least force them to do a thorough inspection of every component in the engine. And that plus proper reassembly (and associated risk) is probably just as expensive due to labor costs as getting a new long block or whole crate engine put in.

Nissan has to reimburse the dealer for labor and parts costs, so they'll probably go with the option least likely to produce a repeat incident. Which that is, who knows.

If it were me, I'd replace the shortblock and be OK with it, but I don't even trust the dealer to change my oil, yet alone the lower end of my motor. That's my concern more so than whether the replacement lower end fixes the issue.

Nissan will only pay the dealer however long nissan says it takes to repair a part, thats how warranty works. Generaly repairs like that take longer than what nissan pays and isnt beneficial to the dealer at all. So they will take whichever route is easier. Id want a new engine too but I dont think its going to happen.

PS: I broke my engine in hard and havent had any oil consumption problems. only time my car ever consumed some oil was before the first oil change and it was only like half a quart.

A new crate engine on a 2009-2010 must be in the order of $10k, so I'd be waving the option of going to court in Nissan's face if it were me. They're likely to cooperate on a repair that serious.

The minimum proper repair here is to have the cylinder heads checked out or at least have the inevitable varnish from an oil-consuming engine cleaned out of them to avoid any future oiling issues. I'd be happy if Nissan paid the dealership to do either.
