Good afternoon natshans,
 
I see you're still searching for the root of the concern; had you already had this diagnosed by a dealership? If so, and if you would like for us to follow up on that with them, please contact us at socialmediagm.com (include your name, contact information, the last 8 digits of your VIN, and the name of your dealer).

#2485 of 2506 Engine noise / 2006 Rainier V8 by malott57

Dec 09, 2012 (7:47 am)

I've got a rattleing noise like something in the wheel weld is fliping but it's in the engine. Buick garage says it's in the #6 cylinder, possible cam & lifters? They say it will be very expensive. Noise happens between 15 & 20 mph, just as it shifts. In 3,000 miles it used 2 qts of oil but there's no oil leaks. No smoke is noiceable coming out of exhaust although there is black stains slightly on the bottom of chrome exhaust tip. Most of the time at highway speeds (70 mph) everything appears smooth. When oil is down a quart or slightly more there is a rattleing sound that comes and goes at 70 mph. I can't get rid of the Rainier because of this but otherwise this is a good vehicle. What can I do with this engine noise and how much will it cost?

I have concern that it only happens when you shift, If it were the cam or lifter, i think it would be an issue all the time. Ask around for a good mechanic that people trust.

You could try going to an automotive store, tell them your problem and ask them if they feel a "LUCUs oil additive may help- it cost about $15 a quart, but its cheaper than an engine rebuilt.

#2489 of 2506 Engine problem by linzeemp

Jan 30, 2013 (11:04 am)

My wife's 2005 Rendezvous Ultra (purchased new; now approx 45K miles) began running rough and its service engine soon light went on. She immediately took it to the local GM dealership (Maher Chevrolet) for service. I've just been told that one of the cylinders is not working. They have ruled out the ignition coil. At a MINIMUM the repair will run $3,600. If we replace the engine the cost will exceed $7,000. Is anyone aware of a serious issue with this engine? I will need to think long and hard about buying another GM vehicle in the future.

That's very strange. Did you get a precise diagnosis---a bad valve, or cracked cylinder head, or bad head gasket or.....the "cylinder not working" is pretty vague, and the dealer should have easily been able to zero in on the precise problem. I'd hate to see the engine torn apart for no good reason. They should have performed a Cylinder Leakdown Test.

I assume you have the 3.6 DOHC engine not the 3.4 OHV engine correct? Have heard of some time chain issues on the earlier 3.6s (which yours is if you have that engine). The timing chain repair is expensive. The 2005 3.4 and 2006 3.5 have been pretty bulletproof. I have a 2006 rendezvous with the 3.5 and 117k miles and it runs great and burns no oil.

Agreed 100% with the previous two posters. We don't have a complete diagnosis here. The engine is apparently running on 5 cylinders - if a timing chain issue had come up I would not expect 5 cylinders to run OK. These engines are pretty bulletproof internally. I would make sure they tested the entire fuel delivery system, electrical, and a leakdown before proceeding. Probably time to get a second opinion. I bet it's something cheap. 2007 Rendezvous 3.5L with 84,000mi and it doesn't leak or burn a drop of oil.
 
Yes all Ultra's had the 3.6L DOHC.

Thanks for the quick replies. Right now I've got $525 in labor in removing the manifold. Will be another $270 if I want to do the leakage test. The leakage test would verify the cylinder failure. To repair the engine would cost a total of approximiately $4,000 (including the $525). I think a second opinion is a good idea. I hate to spend this much money on a vehicle almost 8 years old. Even then the 1 yr./12K miles engine work warranty would only cover the parts replaced. I've got a serious case of sticker shock. Should I do the leakage test first?
