Just got the call from the service manager. They want to keep my car until tomorrow. The engineer ran some "tests" and wants to run some more "tests" tomorrow to collect more "data" I say it in quotes because I tried to ask what tests exactly were done and got a runaround answer.

Day 2 at the dealership.

Service manager tells me that the Engineer wants them to tear the engine down and see if coolant is in the block. And then try cold starting it in the morning. If you refer back to my picture from when they had it for 14 days, it says they performed a leakdown test and it passed. So they're doing the same thing again is what it sounds like. If the head gasket is blown, it's not showing any signs whatsoever.

The amount they're going to have into labour they could have replaced the engine already.

Update. They checked for coolant in the cylinders as if theres a blown head gasket, even though they checked that before. Had my car 3 days this time. The ABS/VDC off/Slip light came on twice today. I noticed a lot of people said to check the brake fluid. I did and it was full just below max. There's antifreeze everywhere as if they took the cap off while it was hot and sprayed it everywhere. Engine grimy and dirty everywhere. I noticed something on both stock air boxes that looked odd...looks like spit, but feels like candle wax or something? Anybody have any ideas? Pics below.

Others have posted that the brake fluid should be right at the max level, not just below. Might want to try that.

Will do, and see if it keeps doing it.

Battery acid, or the tech decided hell with the car :wtf2:

Well...time to get rid of this car. What do you think id get for it on trade in? 43k miles. 3,800$ in aftermarket navigation/speakers/sub/amp/dvd etc all the works professionally installed. Only performance mod is apexi single exit 3" exhaust. Btw, it hasn't been messing up lately...maybe its fixed or something, but im tired of worrying about it. I have 33,000$ tied up in this car and hopefully i can get like 25k on a trade in...it IS a nismo after all.

If I was to trade it in...it would be for something that costs $28,900. About the same miles. Couple years newer.

Just want to share my horror story
 

You've been told that this is not a problem and it's a common issue with the 370Z. They all will do this periodically.

Here let me help:
