The replacement block for me, on both my 350 and 370, was great.

Just expect it to eat some oil as it's breaking in. From what I've seen, it should be largely finished by the 7500mi mark or so.

New short block is fine; no oil consumption at all. Dealer did a decent job.

I really hope you reported this to the NNA?? It's dealers like this who WANT to be fired so they don't have to shell out the money for parts/labor, all to be covered by your warranty. Incompetence. :mad:

It is my guess that dealers make money on warranty work, if they're competent. The paperwork for my short block replacement included a good size bill to be reimbursed by Nissan.

While they do make money on warranty work, there's a particular line they can't cross when it comes to monthly reimbursements from corporate.

If they do too much work, it starts to look like they're just looking for things to replace and bill out to the manufacturer. This is the reason that some dealerships will be hesitant to repair things when you bring them in while others may jump right on it.

Just another reason not to stick with one dealer if they're not working out.

930.5 from my last oil change at the dealer. Follow-up oil consumption test scheduled at the dealer this Friday.

Judging from the dipstick, it looks like that is at least 10mm from the H point of the dipstick.

What do you guys think?

Yeah. The oil rings are toast on your pistons. It is pushing oil from in the crank area into the cylinder. And you have a 6spd. My service managers was saying it is more prevelant with the manuals.

Yay!!! New engine for you!!!


930 miles and you're about 3/4 of a quart short... Motor is toast.
Thanks for playing, lol

That kind of consumption warrants a new block.

1145 miles from the oil change....
follow-up consumption test is tomorrow
I hope I fail!

in the pictures above the oil isnt at the proper temp to be checking it anyways. you should let it get up to 180 at least. then let it sit 10 min then check....

I guess oil use is effected by driving style and time between changes. I've had my '09 Z for 3 years and 11,000 mi. and had the oil changed three times now, (every 3,000 mi.). No oil consumption between changes was ever significant enough to be indicated indicated on the dipstick---none. I'm not complaining---just pointing out different situations. I drive pretty gently and I guess that makes a difference.

To Fuct:

Each time I checked the oil in the pictures below, I had just come home from work which is a 20-25 mile highway commute averaging 70mph+. I waited 30 minutes and then checked the oil which explains why the temperature was under 180. I suppose if I waited 10 minutes, the temperature would be closer to 180 but there would probably be even less oil on the dipstick.

To oldguy:

I noticed oil consumption with this car immediately after doing the first oil change. I agree that the oil consumption became worse between changing intervals if my driving style was more aggressive. However, it is a sports car and I bought it with the intention of driving it hard at least occasionally. It just doesn't make sense to pay this much for a car and then to be carrying around quarts of oil in my trunk.

Update as of this morning on 03/15/2013:

I failed the oil consumption test. The dealer ordered a short block motor which will come next Tuesday. The repair will take two days and they are going to give me a rental car. They gave me back the car and told me to continue driving it until then. They didn't top off the oil because when they drain the oil from the old engine, they want to get an exact measurement.

I think this is probably one of the few times in my life that I am happy to fail a test. :)

hmmmm. 10 min versus 30 i think wouldnt amount for much. i was unaware of the 20 min drive.

soooooo yea, your burning oil. :/

You're absolutely right. My point is that my car is closer to what you're entitled to expect as the owner of an expensive car, whose manufacturer should anticipate is being driven for sport. You are perfectly entitled to a complete remedy.
