Engine 05 Gt Crazy Engine Noise...can't Be Good Any Thoughts?

[greglory]

My first post should be way more joyous then this. This is intermittent and never when the mechanic has the car. Of course I received the typical camshaft position code, mechanic replaced the sensor and drove it a few more times. I get it home and this...

Is there sufficient engine oil? That sounds like an engine running without any oil.
A common cause of the camshaft position sensor code is a bad alternator and if there's insufficient voltage reaching the VCT solenoids, there may not be enough oil being fed to the cam phasers.

That damn thing sounds like a diesel! How many miles are on the car? Is there a Check Engine Light or other lights?

I would check the oil level first then, depending on the mileage, start checking some other things.

That noise comes and goes? WTF? IF you had a cam position DTC then perhaps a VCT solenoid is stuck? I can't tell from video exactly where noise is but I would say don't drive it.

Heard this once before on a 3V. This is the sound of a major cam phaser assembly failure and/or tensioner issue. Get it apart and replace them ASAP.

Bingo. Replaced bank 2 and haven't heard it since. Idle noticeably quieter....so fingers crossed. What a PITA. 100400 miles on engine btw, and no power loss or anything when it would happen...crazy. I can't complain, I've never had a problem with her in the 10 years I've had her. Th a no you guys for chiming in and giving me some starting points!
