You should definitely heed the break in warnings. That would really help. BUT an all out failure like that is still unacceptable IMO. Either way, EVO. There. Now my post has it too. Can we stop that now?

NIZMOZ 09-23-2009 08:13 AM
Okay wait a second. You guys took a NISMO up to 140mph with only 300 miles on the ODO? The car wasn't even broken in. No wonder why you had a failure. I have had my car sit at 160 mph for 30 minutes before several times, never had a issue. And that was on a course not public roads.

I'm also replacing the engine oil (I limped mode remember?) and at the same time installing an HKS oil cooler. Also changed the tranny oil just to be sure. The guy whom I bought the car from has been great and assisting me with everything I need.

I hope my car will be back to normal.

above: the real stinky oil after only 300 miles in the odo. I forgot to take a pick of the deformed drain plug bolt. It has a plastic covering and it was slightly deformed. (the plastic, not the metal parts). Just goes to show how hot the oil was. How could this be? We were going in a straight line. changing lanes was minimal.

I'll know tomorrow if the car is better. I'll prolly Dyno it so it can go 140 mph in a safe environment... see if the diffs boil again (at the same time, get a baseline dynapack reading). better to test it in a shop than in a highway in the middle of nowhere.

Sorry, but diff oil is really stinky..."burned" or not.

+1 on having to take it easy during the break-in period. i can't imagine ragging my car out with only 300 miles on the ODO.

RCZ 09-23-2009 11:09 AM
I had my first trackday at 600 miles on the ODO or something and My car runs great ;)

Zeto 09-23-2009 12:26 PM
Damn I need to check my diff oil.

Baddriver 09-23-2009 03:16 PM
yeah, my fault for not heeding the break in.... but there were other 370s on that day, we are all in a convoy, one was another mt, and atleast 3 others were AT. Yes, they all have higher mileage than my car but I'm quite sure that most of them have yet to break the 1200 mile barrier either. the other nismo that stalled had 500++ miles on it with an oil cooler. I was trailing an AT 370 and not overtaking anyone.

we were in a convoy of 18 cars..... more than half of them have low mileage (bnew gtrs and 370s, porsche panamera, r8).

hey kannibul,

the shop/guy I took it to has been working on cars for a while now and whatever smell it was, they say it's not the usual stench:)

billydsz 09-23-2009 03:33 PM
Insanity driving at those speeds with a brand new car (before breaking in the engine). Throw your money away it's easier.

It's still good that you changed though. I changed both my diff and trans fluid over to Redline at around 2500 miles. (I wasn't having any issues though.) Also, just in case you aren't already aware, DynaPacks are notorious for reading too high. That's just something to be aware of if you're planning to compare your baseline to readings from other makes of dynos. Nice looking Nismo, btw!
hey man! yeah, I will only compare dynapack readings with other dynapack readings. thanks!

the real indication that the oil may have gone too hot is perhaps the molten plastic lining inside the drain plug:) but still the opinion that it's extraordinarily stinky is from the shop guys, and they've worked on cars for a while now.

semtex 09-23-2009 04:16 PM
Molten plastic lining? That's strange. I did my own fluid swap, and there's no plastic lining on the drain bolt itself. The bolt is steel, and there's washer. Are you referring to the washer? The washer is aluminum though, not plastic. Either way, it sounds like there was some sort of sludge stuck to the bolt, which definitely is not good.

it could be sludge....hmmmm. there were 2 bolts, the one in the pick has something black and stuck to it:(

we'll seen soon if it's made a difference.

Yes, there are two bolts. There's a drain bolt and hole, and a separate bolt/hole for filling. Which pic are you referring to? This one?

That's the drain hole, and all I see is a little residual fluid dripping out.

semtex 09-23-2009 04:39 PM
Here is the exploded view of the diff from the service manual, in case anyone is curious.

hmm, methinks the OP is not one speaking from experience.
