Loud ticking noise from engine

DIGItonium

All of this happened without warning? Like gradually increased noise? I think it's bad luck or accidental overrev that would cause the noise to appear suddenly (i.e., something decided to give up out of the blue).

How does your engine idle? Did it increase or become inconsistent? If you get leaks or droplets, I'm pretty sure you'd smell something by now.

That noise is definitely scary. I realized the sound in the video I made were just ticking injectors. Phew! Yours is definitely different.

There were no prewarnings. No noises. Hell I even dynoed the car a couple weeks ago and it registered perfectly acceptable numbers. It could be a high rev that triggered it. I don't drive the car like a grandma and I certainly don't drive it like a pissed off teenager.

They said they'd look at mine today too. I hardly have any mods either. None that affect any of this, that's for sure.

Man I hear you. From now on forever I will check my oil a least a couple times a month, if not once a week, on every car I own from here out.

No check engine light, low oil or anything. I checked the oil temp on my drive home Thursday night and it was at normal range, engine temp was normal as well. I drive mine like a grandma since I'm commuting so far each day and even more so when I have snow rims/tires on which I have currently...some of the easiest 46k miles a car could possibly see

Need an answer quick guys if you can

Dealer said 2 MAF have issues; 1 is no signal, the other is very learn.

1375.00 for replacement

What is our emissions coverage for warranty?

THey are also going to put me on a consumption test as well

Synack

Sorry if this doesn't assist at all, but:

1. MAF sensors are NOT even close to that expensive
2. MAF sensors should not be your fault and should be covered by warranty
- its not your fault your MAF sensors failed.

I'm outside the 3 yr/36k miles on that part so it's no longer covered. He double checked and I found it as well on the nissan warranty information. Sucks that it's not covered but it is better than having to get a new engine. They're going to change the oil and put the tape on it for the oil consumption test so I'll be back within 2 weeks to have it checked.

$1375 is steep especially since it's right there and easy to access but it's cheaper than me having to trade it in to get a new car...but I have another 1k+ expense is tires coming up now too...

As my grandpa always says...it's always something


I found OEM MSRP pricing for a MAFS is 561...I can't imagine them spending that much per but if I were to buy myself I could get it like $450 so I guess it isn't absurd but still...it's a piece of plastic it looks like..

Synack

It's the sensor that reads air in your intakes. So they think your problem is going to be solved with a MAF replacement? I'm slightly under the impression that if your engine is clanking and knocking like mine then that is definitely not a fix for it. But you have a different situation than I do, you have oil. I had none whatsoever.

Yea, they said the check engine light was on (which it wasn't when I had it at home) so they were going to get that to go away and replace the senors. Hopefully that is the cure and no additional engine damage was caused. I'll be back within 2 weeks so if I have any issues I'll be sure to let them know. Mine didn't sound quite like yours...it probably sounded worse than it actually was though...kind of relieved now that it's not the block

Synack

Yeah but what I'm confused about is:

Ok so they replace the shortblock, is that the ONLY thing that needs replacing? It sounds everyone else noticed that their engine was eating oil BEFORE they ran out and started breaking stuff internally. I could be wrong but this is the impression that I'm getting. I believe that I'll have more than just the short block replaced. Though I would much rather that be the only thing that is messed up. And how long is this process supposed to take? I want my damn car back!

Well, if all mine is just the 2 MAFS and my oil changed and cap taped I should have it back today. I'm at work so my dad will go to pick it up for me...after 2 weeks if all is good w/ the oil level and no issues I'll order up my new tires for the Rays...not before then though

DIGItonium

Before the oil change and discovering the shortage, there was noise? Then you changed the oil and noticed unusually high temps plus noise?

So before all of that, did you notice unusually high oil temps as well prior to refilling oil?

I'm thinking something decided to give up, and it's probably just bad luck

Can't wait to see them dissect the motor, though. If the block is still good you can probably salvage it.

Before the oil addition and discovering the shortage, there was the knocking and high oil temps. After 5 quarts of oil, there was still knocking, but I did not run the car long enough to examine anything because everyone on here was telling me to keep it off and have it towed, which I did. I'm willing to bet it would've ran lower though because there was actually oil in it. I'm wearing my lucky items just to make sure I'm going to be in luck when it comes to warranty.
