I had a civic (DX), and it sounded like a sewing machine kind of ticking. Sometime I wondered whether it was the valvetrain or the fuel injection.
"Folks, the answer is neither. There are no valve lifters at all. This is a dual overhead cam engine and there are devices called "roller followers" that transmit movement from the camshaft to the valves...my two cents."
And there's the answer!
(I didn't know it was an OHC engine either!)
"I too generally prefer a split bench to buckets, as long as it has some contour to each side, not just a flat seat all the way across like my Suburban."
Yay! At least someone has one. I'd prefer a big, flat, vinyl bench myself. Tons of stuffing, and springy.
Please, GM, bring this back!
From the specs:
"Valve Lifters = Roller followers, with stationary hydraulic lash adjusters"
The story is different on bikes. Many use "shim under bucket" direct valve activation (in concept like solid lifters in the old performance pushrod engines). This is why they require frequent adjustment. One of my sport bikes wanted valve adjustment every 6K miles!
What I'm looking at is a FM Modulator like this one (http://www.themindfactory.com/Products/PLL-1_FM/pll-1_fm.html), or perhaps a different brand. Has anyone here tried one of these devices, and if so what kind of experience have you had? Is this a add-in that a fairly competent person like myself can do, or would I be better off handing it off to the pros?

I only get them when I go transsonic! You might want to check your insulation. ;-)

Let me know if you find anything out about this. I also have an iPod, and would like to connect it to my TB. thanks!

Only on the EXT. The standard TB still has the 18.7 Gl tank.
What the !@#$$ are "wippers"?? Sounds kinda kinky!
Worse yet, can you imagine trying to change one on the fly? At 300 MPH with a vibrator running wild on the dash - jet engine roaring in your ear - mirrors spinning in cirlces - hydraulic lifters ticking away indicating another time bomb on its way down the tailpipe.
I think you're right, it's getting kinda kinky here.
The service dept applied a "temporary fix". Using a Tech2, they reprogrammed the ATC to "2 Speed Active & Repeat Steps 3 Times". This seems to have stopped the problem from occuring (1st time in a long while I've been able to back into my garage without being in 4WD mode). I wonder though if the AWD will kick in now in the snow.
The service rep said that GM was aware of the problem and was working on a permanent engineering solution. I asked if I was on a waiting list for the fix and his reply was that he thought that there was going to be a recall for this problem. Lets hope its sometime soon.
He also said that the problem may reoccur in the future, but didn't give any indication of what would trigger its reoccurrence.
I have been 'enjoying' my cassette adapter for some time in my Envoy. I had to be persistent -- it would eject the adapter a few times, but eventually it stayed in. Also, I suggest that you turn on the iPod and have it play some tunes while putting the tape adapter inside. The electronics may sense the signal and assume that the tape is in correctly (?).
I elected to go this route after realizing that an aftermarket stereo system would be a real pain -- installation of a special OnStar interface or relocating the radio seems expensive, possibly messy, and would probably get the service manager on my case when I bring in my Envoy for electrical problems.
I'm sure you'll find that the fidelity of the tape adapter is *much* better to that of an FM modulator. Any decent FM adapter will require that you put something between the radio and the FM antenna, so an FM adapter is not truly a wireless solution, either...
Also, to whom who it may concern, I've had my Envoy for a year now, and have put 7,300 miles on it. No major problems yet. Minor annoyances, such as the shift lock not unlocking, the 4WD selector goes on the fritz some times (dealer can't reproduce problem), and the automatic HVAC pretty much sucks -- thank goodness for seat heaters.
I'm still keeping the Envoy, but have been eyeing the Hyundai Santa Fe for my sister.

what replacement WIPER BLADES do you guys like? Winter is coming and these 2 month old WIPER BLADES aren't going to cut it.
So, I'm thinking of just taking them off.
They flap around too much at speeds over 300 mph anyway!
Has anyone experienced similar symptoms? Any idea what it might be? Some bad electronic component maybe that's temperature dependent or?
Any help is appreciated.

1. the 2002 trailblazer is a first model year. Most new model year vehicles have more tsb's than later years.
2. G.M. Tends to be more proactive regarding TSB's
Foreign manufacturers begrudginly list tsb's and usually fight on minor issues that GM would readily issue a TSB.

If you look around for aftermarket triplet exhaust systems, you'll find one from Borla, which is expensive I might add. If you look around for aftermarket Wrangler exhaust systems, you'll find many reasonably priced systems. I'm thinking that I should be able to purchase a cat back Wrangler exhaust system and retro fit it onto my Bravada, maintaining low noise, but yet, streamlining appearance. What does everyone think? Please provide comments.
I'm not so upset with my Bravada's terrible engine knocking and the license plate gasket thing (my build date is 4/01 and I have yet to see a fleck of paint off). HOWEVER, when a vehicle has the MAJOR problems as these have and GM fails to do a MAJOR recall to fix the problems, we need to act.
FOR EXAMPLE:
When you are going 60+ miles an hour on the freeway and your engine just quits on you (several times and it's happened to several posters here) that is a MAJOR problem.
When you come home from a trip and you go to start your vehicle in the parking lot (in the rain) and it will not start that is a MAJOR problem.
Referencing above: When Olds has to replace my battery for the second time because it is faulty and causing the "no start" problems that is a MAJOR problem.
When the rear suspension fails in your 3 month old vehicle and it has to be REPLACED with one that has many of the same problems, that is a MAJOR problem.
Here is my question to those of you who charge us "unhappies" with "whining".
What would your Chevrolet/GMC/Oldsmobile dealer say if you went in and told him that your current vehicle (without specifying the vehicle) does the above things? He would tell you "Sounds like you need a new vehicle!".

Has anyone noticed a cold air source that chills your left foot?
I noticed it tonight driving in 37D temps with the auto climate control blowing heat.
Likely an air leak somewhere.
Anyone find a way to fix this?
worst auto system in four cars that I've had with it.
this will no doubt follow the car forever. I love the ride, but have become increasingly disappointed in the HVAC Sytem.
they fixed this last january with a reprogram and the AC worked in the summer. outside the fact that it zaps power from the motor, it was a good summer friend.
will keep you posted.

Some of the backlash on here, I believe, was due to the volume/repetitiveness of some of the more vocal critics and the existence of "problem" reports that were either trivial or naive (e.g. there's liquid dripping from under my car just forward of the passenger compartment).
By the way, I WOULD be concerned if my Bravada had "terrible engine knocking." Not cold start ticking or cheap gas pinging, but knocking. No engine should have that.
I cannot tell you how embarrassing it is to have people, both outside the vehicle and inside, ask me "what is wrong with your car" as I am accelerating and everyone around hears it.
I guess my whole problem with this vehicle is GM itself. I've been fortunate to have nearly flawless cars in the past (I had a 1998 Buick Century Limited for three years that NEVER went to the dealer except for the standard oil changes) and I hate to have the service people (not to mention the sales people WHAT KIND OF AN IDIOT SALES PERSON WOULD TELL SOMEONE THE BLACK DOTS ON THE WINDOW ARE FOR THE SATELLITE RADIO???????) look at me dumbfounded when I hand them TSBs or other knowledge about the car they know nothing about.
ARRRRGGGGHHHHH
I activated On Star and had them run a diagnostic. They found a drivetrain PCM code, turned on the service engine soon light, and linked me to my dealer so I could tell them I was bringing it in right then. So, it is at the dealer now. I will report what happens. Those who have had this problem in the past, you now have my complete understanding and sympathy. I will be glad to get it fixed, as I still love my Envoy every time I drive it.
Thanks.
