Oil Check Please!

[FSUZ33]

I see it as Nissan will certainly key on that 'modification that involves oil circulation probably causing the starvation' route. A catch can has been proven its worth over and over in the long run, i.e. valve deposits, but it's still not OEM. Ugh!!

If the industry would start calling them Air Oil Separators like Porsche and others do maybe it wouldn’t have the same stigma attached.
Ive got one, for the record.
Tried to think from his perspective. If I had glitter in my oil and needed to take it to the dealer, what would I be concerned about?

They sure are technically Air Oil Separators. I installed the high capacity aftermarket UAOS which I drain after each track day from my Cayman S, 3-4 oz typical collected.

There you go. Just like the Latrine Colonel Welcoming Device. The proper name is everything.

I have many questions...

For now, Im here to follow to see the results to your finding and how Nissan will handle this.

Safest option is to always remove all aftermarket parts prior to a dealership trip for a major issue. Yes, you could litigate the Magnuson-Moss claim, and spend a lot of money on legal aid and time, or just spend a bit of time up front to avoid the issue. Looking at your creamy latte oil with a double shot of forbidden glitter, I'd err on the safe side.

Has anyone here been denied warranty service because of added catch can? If that's a red flag I might reconsider installing mine, but will ask my local dealers if it's a potential claim issue...

Manufacturers cannot void warranties in the US, they can only deny warranty claims if they can prove something you did caused the issue that would have been otherwise covered by the warranty. If they won't even look at the issue because of a catch can or other simple bolt ons then you should contact your local consumer affairs department and file a claim against the dealer.

Spending 2-3 hours removing mods before what is likely going to be a warantied engine replacement is less risky then the (small) chance that the dealership throws a fit about mods.

It's crazy we've seen another bearing failure one these forums in such a short time.

kcbernard2000 did you ever see a high oil temperature warning?

Speaking of, anyone know what actual temperature the warning comes one? I’m always watching all of my gauges and I’ve never seen any get close to the dreaded “red zone,” including the oil temp gauge, but the gauges have no numbering.

Hmmm… per Google, it’s 280F.

- Nismo intakes, Z1 catch can, 2.5" lower down pipes, Nismo track exhaust, no tune.​

How long you've been driving with the lower down pipes and no tune? Is your dealership still servicing your car with 0w20?

as mentioned by others before, looks like the oil is milky and glittery. Which could suggest coolant mixing with the oil and bearing wear in the engine, which is no beuno. Likely first signs of engine damage

I'd take out all the mods and make it stock as best as possible. Have Nissan check it out, hopefully they can cover it under warranty (good thing you didn't get a tune yet eh). But yea, oil looks cooked

 

[FSUZ33]

Good point @Hernandooo

Complete speculation, but here goes…

Generally frowned upon to run LDPs without a tune, but I don’t know what SPECIFIC issues and failures could result from that. As I posted somewhere here before, if you search (Edit: VR30 in general, not specifically the Z) you’ll find people saying not to run without a tune as they had engine failure at some point. And others that say they‘ve been running that way for a long time with no known issues.

It’s also said (unsure if it’s proven) that the cause of oil pump control solenoid failure is crud/particulate buildup.

Could this be a condition(s) resulting from running LDPs without a tune that allowed coolant into the crankcase, starting the bearing wear. Then, maybe, killing the solenoid exacerbating the bearing wear?

The way the pan looks it doesn’t appear to have been happening for a long time. Not sure if a little coolant in the oil would start wearing the bearings down that fast. But IF the solenoid failed (regardless of cause) AND there’s coolant in the oil it could start peeling the bearings quickly when you’re ripping it.

I’d really like to know as much as possible about this, but he hasn’t responded, so not sure if we’ll ever know anything more about it. If anyone sees these pics on other sites please report.

Honestly, this could just be water from not driving it enough. 4th oil change at 5600 miles and if you don't drive long distances (30-40 mins) high temps to burn off water.

I'd say just change the oil and send it. If you have a good relationship with your dealer, you will have no issues at all with minor mods.

Less risky, time consuming, possibly labor intensive, and for those who aren't mechanics or don't have the means, very costly.

I would run a Blackstone analysis to make sure what's really in the oil. This is good to do ($40 per analysis) for ongoing health check. Turbo engines get quite sensitive with oil viscosity, longevity.
