Replying to: gamleged (Sep 19, 2007 12:39 pm) Same here. Like a poster somewhere on this forum noted, if I didn't watch the tach I would not even know the engine started.

Replying to: mjbek (Sep 19, 2007 10:37 am) Note that there is a TSB concerning the cam chain tensioner on the Azera. The tensioner is hydraulically controlled and uses a ratchet mechanism to hold it in place when the engine is shut down ( it would otherwise retract due to loss of oil pressure ). The teeth on some of the ratchet mechanisms wear or shear and do not hold the tensioner in extended position. This causes a rattle of the cam chain on startup until oil pressure extends the tensioner. This would explain a slight rattle for a few seconds after startup.

Replying to: cobrazera (Sep 20, 2007 2:14 am) Thank you all for you responses.   My Azera shakes for about four minutes only when it is cold, then it smoothes out when it warms up (or idles down). During the day, I hardly notice the engine started as some of you mentioned. I have heard of the problem with the oil reaching the mechanism which last a few second only.   How can I access the TSB?   Thank you again.

#16 of 18 2007 Azera engine noise by dres Oct 06, 2007 (10:50 am)
When I brought home my new 2007 Azera I noticed that the engine was quite noisy. When it is started for first time in morning, it has a loud mettalic clang for 3-5 seconds (al;most like there is not enough lubrication?). Dealer tested oio pressure -said that this was "within spec" - that it could take up to 3 seconds to build up oil pressure. Any other such experience? What did dealer say or do?

Replying to: dres (Oct 06, 2007 10:50 am) You might have a faulty timing chain tensioner. There is a factory Service Bulletin 06-20-002 that addresses this problem. It is a warranty item. They replace the tensioner.
#18 of 18 Excessive Engine Noise by sardone Oct 15, 2007 (5:21 am)
After 8,000 miles my Azera's engine began to make excessive noise. I took it into the dealer and I was informed that there were loose bearing on the main engine fly wheel. After two days in the shop and the lifting out of the engine the repair was completed and the engine is again as quiet as when it was new.
