Valve covers replaced, new plugs, new pcv valve, compression good, no oil leaks.

Did it all after 1k miles of oil consumption. I now use conventional motor oil and change oil and filter every 2 k miles.

Well the dealer ship said it's good for high mileage cars... idk..

Timing chain O_o

130k 05 G with major service done at 100k. Runs like a charm!

what major service? or are you just talking about what infiniti recs to be done?

I'm at 99,600 miles can I play?

Purchased the car March 09 with 46,000 miles, dropped it 3" last year, and have done the following:

Replaced both front lower control arms
Fixed axle click myself
Changed plugs at 60K miles
Changed both drive belts at 60K
Performed all regularly scheduled maintenance

I need to replace both of my front ball joints, front endlinks, and my rear diff bushing, they are all shot. Understandable driving low for that long, will replace the ball joints with the Megan Racing roll center adjusters. I'm expecting the bushings on the comp rods to go at some point, but as far as major mechanical issues, I've had none. Plan on running my girl to 200K or more if she'll get me there.

Please post up a thread when you do the Megan Adjustable joints. I am really interested in those Tim!

Will do, it'll be after the first of the year though, got a couple more things to get for my DD build first.

Bump. Anybody know any G owner with 250k or more?

2003 G35 sedan...141k
replace both lower comtrol arm and compression rod bushing, thermostat and rack and pinion..beside that she runs like new...

2003 5AT sedan 183k consumes 1 qt every 1k... maintained properly so far only issues have been a tatered radiator, and some crazy computer thing that had my ac stuck on full blast and stereo wouldn't work.

2003 sedan
154k
No problems yet, change oil every 3k spark plugs changed about 4 months ago. And transmission fluid changed at 140k

I have a 2003.5 G35 Sedan I've owned since new that just turned 155K. I've run Mobil 1 since new and have never had any engine problems. I've followed the factory maintenance schedule (never the BS the dealer tries to sell!).

Here are the major items I've replaced over the past nine years:

Windshields: two so far due to stones from trucks.

Compression Rods (Front suspension): two sets so far, they seem to go around 80K and its $600 at the dealer.

Rear Rotors: finally got too thin at 110K - always change the pads before they get too thin.

Rear Calipers: 140K they were frozen and expensive dealer-only part - about $225 each!

Front Rotors: finally too thin at 90K.

Front Calipers: just replaced them this weekend with NAPA (actually Tokico units) that were only $75 each with the bracket versus $320 each the dealer quoted!
Shocks/Struts: replaced at 125K with a nice set of Bilsteins.

Exhaust: muffler to resonator pipe rusted at 130K so I replaced system from cats back with a Borla system. Great sound on acceleration, but way too boomy at 2000-2500 rpm.

Ball joints: dealer replaced all at about 100K. Might have been overkill, but I'd rather have them all replaced at once to maintain the tight steering feel like new.

Hood hinges: be careful leaving your hood open in high winds! While giving a neighbor's car a jump start, the high wind took the light aluminum hood off the prop rod and slammed it against the windshield, rendering the car undriveable! While the hinges only cost $30 each, you have to take the whole front clip off to replace them, so I had the whole front end repainted.

Hands down, the best I've ever owned!

Just turned over 235k in my 03' Sedan. Hoping it makes it to 300k!
