The 2007 Fairlady Z (350Z) with the VQ35DE is a generally robust sports car, but the manual transmission can suffer from internal wear, and the VQ35 is notorious for timing chain guide failures and oil consumption issues as it ages.
Timing Chain Guide and Tensioner Failure
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Cold-start rattle lasting 3-5 seconds, Metallic rattling from front of engine under acceleration, Check engine light with cam/crank correlation codes, Complete loss of power if chain jumps timing
Fix: Requires front engine teardown to replace timing chain, guides, tensioners, and usually all three chains (both secondary and primary). Book time is 12-16 hours depending on whether heads come off. Many techs recommend doing head gaskets and valve cover gaskets while in there.
Estimated cost: $2,800-5,500
Manual Transmission Synchro Wear (5th and 6th Gear)
Occasional · medium severity
Typical onset: 60,000-120,000 mi
Symptoms: Grinding or crunch going into 5th or 6th gear, especially when cold, Difficulty downshifting into lower gears, Gear pop-out under deceleration
Fix: Transmission must come out for rebuild or replacement. Synchro rings and keys are the culprits. Expect 8-10 hours labor for trans removal, rebuild, and reinstall. Many owners opt for a used transmission from a low-mile car instead of rebuild.
Estimated cost: $2,200-3,800
Oil Consumption from Piston Ring Wear
Common · medium severity
Typical onset: 100,000-180,000 mi
Symptoms: Blue smoke on cold start or hard acceleration, Burning 1 quart per 1,000-2,000 miles, Carbon buildup on spark plugs, Reduced power and misfires if oil level drops too low
Fix: Piston rings are the root cause, which means engine-out rebuild or replacement. Some techs will do a top-end refresh with new rings and hone, but most recommend short-block replacement or full rebuild. Book time is 20-30 hours depending on how deep you go.
Estimated cost: $4,500-8,000
Transmission Oil Cooler Line Leaks
Occasional · low severity
Typical onset: 70,000-130,000 mi
Symptoms: Transmission fluid drips under car near radiator, Low trans fluid level on dipstick, Burnt smell if fluid is low long enough
Fix: Cooler lines corrode or develop pinhole leaks at crimp points. Replace lines and top off fluid. Labor is 1-2 hours depending on line routing.
Estimated cost: $200-450
Engine Lifter Tick and Collapsed Lifters
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Persistent ticking from valve train, especially cylinder 5 or 6, Tick worsens with heat, Misfire codes if lifter fully collapses
Fix: Valve covers come off, camshafts out, replace failed lifters and check cam lobes for scoring. Labor is 6-9 hours. Often done alongside timing chain service if already in the front end.
Estimated cost: $1,200-2,400
Transmission Mount Failure
Common · low severity
Typical onset: 50,000-100,000 mi
Symptoms: Clunking or banging on hard shifts or throttle lift, Excessive driveline vibration, Visible torn rubber on mount inspection
Fix: Replace transmission mount. Labor is 1-2 hours, straightforward job. Polyurethane aftermarket mounts last longer but transmit more NVH.
Estimated cost: $150-350
Owner tips
Change oil every 3,500-4,000 miles with quality synthetic to minimize timing chain wear and oil consumption.
Use OEM Nissan Matic-S fluid for the 5-speed auto or GL-4 75W-90 for the manual; wrong fluid accelerates synchro wear.
Inspect timing chain area for rattle during cold starts annually after 80k miles — catching guides early saves thousands.
Check transmission fluid level every oil change; low fluid from cooler line leaks can toast the trans quickly.
Great driver's car with a bulletproof chassis, but budget $3,000-5,000 for timing chain service and be prepared for transmission work if buying high-mileage.
