I kinda want to start this post just to see who actually drives their cars, but at the same time I want to see what kind of issues have arose at certain points in a C6Z's life so others can know what to expect. I'll start with mine. Let's see what you got.

09 Z06 - Intake only. Stock to 123k miles. Original Heads. Routine maintenance only.
128,156 miles

Im not high milage yet @ 27,XXX miles but I bought this 07 with 16,6XX miles on it last December. Heads, cam, twin disc clutch, full exhaust, lowered all the way on stock bolts

TomcatMF

2007 with 67,000 miles, and I bought it 3 years ago with 15,000 miles. I've had an O2 sensor go out, and the bi-mode exhaust control module went out causing all kinds of crazy things to happen. Other than that it has just been normal maintenence.

Just turned over 50k on my 2009 E-force Z06. And it sat for almost a year while I was out of the country.

GM needs to take your heads off and study them!

njk4o5

there needs to be a poll thread for the head problem. curious to see how many cars over 50k have ever had a problem.

mines got 41,000. heads checked at 31k and they were perfect.

2006 Z here. Just hit 125k miles yesterday. Stock until ~117k or so. Now has a tune (MTI of Atlanta) headers and exhaust. Bought the car last July with 107k miles. No issues since then.

Whats up Don?! I saw all the new goodies for the car yesterday on FB. Car is already bad ***, I'm going to need to go for a ride when you're finished so I know what to look forward to when I finally start doing upgrades.

...just to comment on that, traded in my 06 in 2011 with 109k miles on the clock, with no head problems that I knew of...

v8sten

No problem, we will be at Gary's tearing my car apart this weekend if you wanna stop by, you will never look at yours the same way after riding in mine

LEJ ZO6

Mine doesn't have as many miles as some but it is getting there.

2008 ZO6 with 82,000 miles. No problems with this car, ever.

2006 LMB. Bought it at 20K miles in Dec 12'. Turned over 50K miles this month. Heads never been checked. CAI and deleted mufflers are the only mods. It has had both driver and passenger window regulators replaced, AC unit + condenser and the fuel tank sending unit. Good thing I purchased a 3rd party warranty on it. $2k has paid off in $5k repairs.

TheTinMan

They can have them pretty soon. Granted they have lasted a long time, i feel that they will be replaced soon because they are getting more and more noisy. The last owner was an older guy that put a lot of highway miles on it and never really pushed it. Since i've had it i've been pushing it like it was designed for.

Go figure high mileage Z06 with zero major issues..The chicken Littles will rain down on this thread very soon...

dmuellenberg

2006 LMB bought new in March of 2006. Stock except for exhaust and wheels. 101,650 miles on it as of today. Had the heads refreshed at 100k, a couple of the exhaust guides were out of spec. Had the roof recall done and replaced water pump at about 80k - other than that, just regular maintenance.

MasterDave

2007 Z06, bought december 2010 when it had 300 miles on it. It now has around 23000. No issues at all.....except I would not recommend washing the engine down. The 64 don't care, the Z had a mind of its own until I disconnected and cleaned every connector under the hood.

lbzraptor

07 Z06, Around 58 thousand miles. Had heads and cam done around 42000 miles . Installed bronze guides and reused all valves.

Undy

105K miles. H/C/I @ 88K. All valves guides were in spec at the time.

sbrooks64

It's good to know people are getting high miles without valves dropping. Have you tracked your cars or are they DDs

TheTinMan

I track mine and its my DD as well haha. Mostly AutoX. Couple times at Barber, once at a track day at Talladega. Trying to get on Harris Hill and MSR now that i'm in Texas.
