Loud ticking noise from engine

They're going to have to pull and re-install the whole engine either way, so any risks from that are common to both solutions (e.g. errors in the installation process). The VIN on the lower engine block is going to change either way, if it's the matching VINs you're worried about value-wise.

I'd rather have a whole new engine in that case than have them slap in a new shortblock + existing heads. You get newer everything for free, and less chance of some unseen fallout affecting the heads' longevity. How well do you trust that their mechanics would notice (or even be *able* to notice) some subtle problem that developed in the heads from running oil-free?

I understand where you're coming from. Either way I hope I don't get a new block or new engine that has less power than my current one. I've heard of some people with pretty low dyno numbers and that makes me a bit uneasy. Would be cool if I got a factory freak though. More importantly I want the car back with a well operating motor that doesn't eat oil in a relatively short period of time. Like by the end of this week.

I think it more likely that you have heard of people who went to mean dynos and nice dynos.

Good luck on the repair! Sounds like your dealer is being straight w/ you.

They can probably do an whole-engine swap in a few days time given scheduling constraints, they dropped mine out in the past for a quick header installation with no problems. With the added complications, though, of inspecting the heads and waiting for major parts shipments (I imagine short blocks and whole engines aren't something they keep waiting on the back shelf at the dealership), I think it'd be wishful thinking to be back on the road in a week.

wstar · 02-27-2012, 03:01 PM

(And I wouldn't worry about the Dyno numbers. Factory freak-ness is never more than ~1%, the rest is just different dynos and different atmospheric conditions, or factors other than the engine (e.g. gearing, wheel size/weight, etc)).

specblue02 · 02-27-2012, 03:06 PM

I thought I heard incorrectly when I was on the phone with the service guy but he checked with the mechanic who was working on my car to confirm but they indicated that burning 1 quarter per 1000 miles is considered normal. Nissan has higher requirements of 2500-3000 miles to burn 1 quart...still I think that's pretty ridiculous...I'm at work so my dad is going to pick it up now but he's going to question that...seems a bit high, don't you guys think so?

The factory freak is a myth -- here's the kernel of truth (at least to the best of my knowledge): Older GM cars occasionally had a different cam put in on the assembly line when designated cams were short on supply, and because so many parts were interchangeable. If the different cam happened to have a wilder profile, you lucked out with a more powerful engine.

Well this makes sense as to how I was introduced into factory freaks, first new car was a GM. I had a Chevy Cobalt SS for 5 years and we saw some that would come 185whp from the factory and some up to 235whp, the Supercharged version (2005-2007). Nobody saw any factory freaks out of the turbocharged version (2008-2010).

Glad to hear they are taking care of you.
I would not worry about the extra time honestly, an extra week or so to get a full replacement is better than just doing a short block and then having more problems down the road.

If not you can always roll in an Altima, I hear they are the new in car.

sfearl1 · 02-27-2012, 03:15 PM

so my Z has the date: 07/10 in the door and has the beginning VIN of JN1AZ4EH

does this mean i'm affected by the TSB?

It means that if this same exact thing were to happen to you then you would be covered if you're under 36,000 or have an extended warranty.

Trips · 02-27-2012, 03:18 PM

Good to hear their doing the right thing

Interesting thread. Since I just got my Z so I'll definitely keep my eye on the oil level. Anyone got a link to the TSB? If it was posted sorry I missed it.

I haven't had mine long enough to do the first oil change, but I do all my own work. I'm OCD so I keep all my receipts from oil changes as well as a maintenance log book in the car (helps with resale).

I see a lot of misconceptions in this thread as well revolving around warranty. Dealerships CAN NOT void your warranty for doing the work yourself unless they can prove you caused the problem. There are laws against this. The only way a dealer could have such a policy is if they provide free oil changes to their customers.

It's the same reason they can't force you to use their oil or filter.

To the OP, it wasn't the Mobil1 that was the issue. If you burned 5qts in 5,000 miles there was something major wrong going on.

Maybe these cars need a 5W40 or 10W40 weight oil.
