I have had my 2005 SRX into the dealership 4 times trying to solve a loud sticky lifter or a water pump bearing going bad sound. The dealership and GM claims it is carbon build up from using high octane gas. The dealership did several de-carbonization cleanings of the engine without any luck. They even poured a quart of Zmax Micro Lubricant into the engine to stop the sound. Has anyone else experienced this problem?
Check out this article:
V8 or V6?
My V6 had a bad camshaft which made a sound like a bad bearing.
Both left side camshafts were replaced plus the retainers.
My delaership had another SRX do the same thing a week before.
You can do a search in this forum under "camshaft" and my thread should come up.
That's odd to me that you would get carbon build up from using high octane gas, since -- assuming you have a V8 -- high octane gas is recommended.
