Life span of a VQ37?

SPOHN · 07-18-2013, 10:19 AM

I've seen a 350 with 220K miles. No issues.

Actually seen 300K on a VQ35 in a Maxima

Are you sure it wasn't an AWD turbo eclipse?

First off, I think you're already fully aware of the differences between an automatic and a manual. Your old car involved hitting the gas....and that's it. It's going to take some getting used to, especially with the Z's finicky transmission.

60k miles isn't a lot, but some basic maintenance will certainly improve things. Resetting the ECU might also help. I could be mistaken but I think ECU learns from driver input. If the previous owner was easy on the car, the ECU may have adjusted.

If all else fails, buy some mods and have it tuned with UpRev.

Yeah reset ecu and drive like you stole it

Most people forget to change the blinker fluid. Doing that can prolong the life of your engine by tens of thousands of miles.

Ecu reset and k&n filters installed...all I can say is WOW world of difference. No hesitation after a shift at all. Still cant get the tires to break loose but oh well. Im feeling a switch to 4.08 gears anyways. Ill never need to do 170 and i read that 0-60 time is around 4.5 or maybe lower with the swap. On a lighter note i walked into advance and there was a young couple coming out and the girl sayed wow wat is that and the guy ah its just a 350z haha she obv has better taste than he does.

A well maintained engine and not abused engine will last hundreds of thousands of miles. The rubber and plastics will break down before any mechanical failure baring any defects missed at manufacture.
My family drives a lot of highway miles and usually get over 200k miles with only one mechanical issues from the engine on about 7 cars. The one engine failure was in a 79 Camaro where a push rod broke. Everything is standard maintenance and 3k ish oil changes.
This is the main reason why so many manufacturers have been increasing their power train warranties.

I know the plugs are supposed to be good for like 100K or something asstronomical. It still might not be a bad idea to change them now. And here's why. I had a 2005 Frontier that was running like a$$ right around 70K. Figured I change out the plugs and give it a good tune up. When I pulled the wire off the #6 plug, the head was full of oil thus covering the top of the plug and wire boot in dino piss.

I googled the find and surprisingly enough, it is quite common among Nissans in general. A lot of hits on Frontiers and Maximas. Sure, some go forever with no issues but it was common enough to be found on various forums. If I recall, the fix was to replace the seal on the intake plenum but it was just short of ripping the top end of the motor apart on the truck. So I cleaned it out, changed the plugs, and ran it to the dealer to trade in. (Another reason why I never buy used).

Long story short, there is a guy on here with 100K and no issues. Not a lot of folks are racking up crazy miles just yet, so who knows what quirks might surface when more of these motors get higher miles.

Change plugs and filters. Get an oil analysis when you next change the oil. Change brake, diff, tranny and clutch fluids. Get an alignment. That's about everything I can think of when buying a used car.

Zensation · 07-18-2013, 11:07 AM

Yeah i had a 350z and there was always oil in the plugs just bc of an o-ring that happens a ton. Im an engineer at a facility that makes seals and gaskets so thats where my expertise lies if you could call it that. I wasnt so much worried that the engine is worn out but that it may not be producing its peak hp anymore. Ill deal with it i can live with how it feels now haha. Thanks for all the support guys! I love how close knit this forum is.

And power steering fluid IMO

Chuck33079 · 07-18-2013, 11:16 AM

I knew I missed one.

That might be part of your prob right there. Those tires aren't that great, especially compared to the Yokohama and Bridgestones that come stock with the Z
