Lets play: What's That Horrible Sound! (Video)
Hi CL,
I took this video this morning, seems to be coming from the Cam Timing Control Module area. It starts about a minute after cold start, but goes away once the car has reached normal operating temperatures. In the video you'll hear the sound im referring to come in and out. Sounds like a metal knocking, then goes away, then returns. Performance doesnt seem to be affected, occassionally there is an ever so slight rough idle when in sitting at a light. MY 2008 with 107K kms on the odometer. Any insight as to what it might be would be greatly appreciated. Thanks.

I think your problem is the TRD oil filler cap. You must remove it and send it to me.
But seriously, what viscosity/type of oil are you running?
There have been a few threads on this lately regarding the solenoid side of the system, but the the other side is oil pressure driven. Have you puled codes from the ECU yet? Anything pending?

Thanks for the feedback guys, appreciate it.

The $1M question is: what needs fixing? Im going to stop by the dealership tonight and show them the video. Its hard to demonstrate the noise in person, because like i mentioned earlier, it only makes that noise between about 2 and 5 minutes after a full night sitting. Once it goes away at that 5 minute-ish mark, it wont make the sound again all day. Weird.

It definitely sounds like the vvt about to sh#t it self have you thought to take the serpentine belt off and start it cold idle pulley etc.........long shot .
Also cam chain tensioner or guides put a stereoscope on it and you Will know where the noise is coming from .They are cheap at any auto shop good luck and let the forum know what happens cheer.

Sounds familiar.
It's a leak in the seal between the valve cover and the cam cap feeding the exhaust VVTi OCV which controls the variable timing on the exhaust cam. Open the oil cap while it is doing this and see if the noise gets louder. Mine does. The noise will go away completely if you remove the valve cover(s) and replace the seals between it and the cam caps. Only for a while. Then it will return. AMHIK.
It gets worse with time and mileage.

If you plan to remove the valve covers, this is the list of suggested parts:
11193-38030 = 8 - Gasket Spark Plug Tube
23224-38010 = 2 - Gasket Fuel Pump Spacer
23915-46011 = 2 - Insulator Fuel Pump
23279-74010 = 4 - Gasket Fuel Pressure (Pulsation Damper)
11229-38030 = 2 - Gasket Cylinder Head Cover No. 3 (Valve cover oil filter)
11159-0P010 = 2 - Gasket Camshaft Bearing Cap Oil Hole No. 1
11159-0S010 = 2 - Gasket Camshaft Bearing Cap Oil Hole No. 2
90301-A0029 = 4 - O Ring (Oil Drain Pipe)
11213-38060 = 1 - Gasket Cylinder Head Cover No. 1 RH
11214-38040 = 1 - Gasket Cylinder Head Cover No. 2 LH
90301-09028 = 1 - Oil Tube O-Ring (dipstick tube)
90210-08045 = 6 - Washer, Seal
15678-46020 = 2 - Filter (for the exhaust cam oil control valve)
Also, be cognizant of the fuel connections. If you connect them wrong, the engine will run, but no more than idle for a short period. AMHIK.

So i thought you said the p0012 code has nothing to do with the vvt solenoid on the exhaust cam side... so your saing this code is from the the orings between the valve cover vvt solenoid ports and cam cams??
