2010 - Low oil pressure, possible metal particles in oil...
Update: the shop called back and said they did not find any sign of shavings or contaminants in the oil pan. So I think I probably should have them replace the gallery gaskets. But man I still feel like after doing that, the code will come back because the vvt solenoids will be dirty, and it's probably another grand to replace one of those lol.
Edit: they did check the vvt solenoids, said they look fine.
So I've had this 2010 Maxima Since 2018, bought it with 60k miles, and have loved it. Fully loaded with everything, And the mechanic I took it to said it was one of the cleanest cars he'd ever seen. I didn't know about the CVT issues at the time, but learned shortly after. So I replaced the transmission fluid around 65k, and was planning on doing it shortly here soon again, it's got about 89k on the clock now. No slipping, transmission shows no signs of slowing down at all. So it's been taken care of and treated me great. I've done the oil changes myself on it, and done them pretty much on time all the time, and kept up on most of the other maintenance.
However recently I got a P0011 on it. I had this before a few years ago, and Nissan replaced one of the VVT solenoids. But it's popped up again, and now they are saying they suspect the timing cover gaskets may be worn, because the oil pressure is a bit low, and they see what they think are very small metal shavings in the oil, around the oil filler cap. They are going to drop the oil pan tomorrow morning to verify if they see them down there. There have been no other symptoms besides the code. Gas mileage has been fine, no noises, sputtering, anything else.
My question is, if they do find oil shavings down there, what are my options? They want $2k just to replace the gaskets on the timing cover. (can't remember the actual name for it). But they said at that stage, they would get me a quote for a new engine. I don't plan on forking out for a new engine. I always assumed the CVT would go out eventually, so I would drive it till then. But $2k only fixes the oil pressure issue, but doesn't fix the damage already done.
What is the state of an engine with fine metal shavings in it like this, and how much life could it possibly still have in it? Could I drive it for another 10-20k? (knowing I only put about 3500 miles per year on it) Or do I trade it in somewhere while it's still in good condition, just to get it off my hands and move on? With the oil pressure low, oil can't get up to the spots it needs to and it's just going to keep getting worse. I just don't know how long I have before it's going to be worth nothing.
I realize it's not good, and I shouldn't expect much out of it, but I'm wondering if it's better to cut my losses now and trade it in, rather than run it into the ground and get nothing for it. Thoughts?
