Yep. And tolerances have gotten way tighter over the last 30 or so years.

I do bet you will see variance due to break-in success or failure -- that probably accounts for anywhere from 1% to 3% (poor ring sealing, lost compression) to 100% (blown motor! :p )

Anyway, OP, glad to hear you are getting a new short block and no BS from Nissan :tup:

Thanks, gonna baby it through break-in. Possibly unlike the previous owner...

Sounds like you got a good dealership. Well assuming they don't screw the work up!

Zemurray 02-27-2012 07:50 PM

Really glad they are taking care of you. That's great news.

Have the dealership do an oil consumption test. My car failed the test in august. Their is a technical service bulletin about this oil problem. I had the short block of my engine replaced as a result. Don't worry, all covered under warranty.

I think in this situation he is way past that (Engine is shot) He is getting a new engine anyways he said.

It's either short block or whole engine. They haven't told me yet.

Either should solve your problem, if its oil consumption issues...

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.

Synack 02-29-2012 03:56 PM

UPDATE!

Replacing short block under warranty. Will update with what happened and what broke. 4-5 days work.

DEpointfive0 02-29-2012 04:02 PM

Whole engine
 
Tell them to replace the whole engine!!! I KNOW Baker South has a complete engine from Nissan sitting in the service booth!!!

DEpointfive0 02-29-2012 04:03 PM

Oh, and another reason to buy the extended warranty, LOL

Already planned on it.

Synack 02-29-2012 05:27 PM

Why replace the whole engine when he's getting a short block?

DEpointfive0 02-29-2012 09:21 PM

Why not? It's free? And it will take less time for an engine swap... The Nissan book says 13.2 hours I think...


On another note, just checked my oil. Damn car hasn't used a drop of oil in 1500 miles, it's EXACTLY the same... I guess no new engine for me...

Because it comes down to money, and why waste a long block, when a short block will do the trick?

Ah, now the strategy dawns on me. Buy one of those suction oil change pumps that extracts through the dipstick. Claim consumption, pull 1 qt every 500 miles while they do the test, get a free new block. :tup:

Ron 03-01-2012 08:05 AM

They put some sort of tamper proof seal on the dipstick so that you can't do that lol. U can always drain a little bit from the oil pan, not sure if they seal that too.

Gm uses a sealant on the drain plug/paints a witness mark on it. I suspect Nissan thought of it, too.

Labor nigh offset it. Also, a service department is not the best environment to rip the whole thing apart in. There is also the caveat that the dealership employees don't have the hands on that the original builders do, etc.

ImportConvert 03-01-2012 08:25 AM

Further, if the bottom end was starved, who is to say there isn't damage to the top end? Just because the bottom end is what caused the noise doesn't mean the top end isn't damaged too.

Sound like you spun a rod bearing maybe two. Yes good thing you had it towed it could throw a rod through the block running it much more. Right now it's just chewing into the crankshaft.

Cool I hit it on the head! Maybe I have missed my calling as a mechanic. Although, I would only want to work on exotics. LOL!

Great deal they are getting it done. Post pics I wanna see.

None the less, they probably found no symptoms of failure in the head to denote a full long block. Heads (especially in this car) are expensive, not to mention the intake manifold and other goodies. They simply wont change that out unless they know they have to.

You can pound your fists all your want, but unless he can prove damage to the top end, he's not getting it.

Price difference on a short block vs. long block is probably much more than the few hundred bucks it'd cost to transfer heads and intake manifold over to the short block.

You're basing your argument off of "maybe"'s. MAYBE his top end has damage. MAYBE they decide to hand a head swap over to some inexperienced twit in the service department.

Or maybe, it'll just all go well.

And in this case, the shop is known to be high quality. They've worked on my car, and I'd trust them in general.

Yup. In fact, here's some footage of them doing an engine removal:
