P0011 2 years after gallery gaskets

husam2012

What oil are you using? I would say it sounds like the factory screws loosened up somehow. 13 psi is definitely too low but it depends on your oil type. Most vehicles that I do gallery gaskets on end up having atleast 20 PSI with hot oil temps, most being above 25psi.

THE BULL

So a bit of background:

The engine has never liked 5W oil. I find that it produces a bit more metal than 10W. I've been using 10w- 30/40 depending on what's available.

I've been using Fram Gold Titan filters for 3 years, this specifically happened after I got an OEM Titan filter from the dealer. Former employer and I know the part department so I asked them for a Titan filter (hopefully they gave me the right one though to my understanding ALL titans are the same, never checked the part number)

Almost instantly started to experience this. Then hooked the oil pressure gauge to diagnose further.

The jumps in this pressure I contribute to VTCs engaging and disengaging.

Erratic pressures happen at all times however VTCs respond better prior to oil reaching operating temps. After 1 hour of driving I can see pressures drop a bit at idle 1 psi or so. Pinging is much more prevalent if I stay within 1.5-2.5k RPM

In my opinion it seems like a leak in the gaskets however possibly in the upper section, specifically affecting Bank 1 more than 2. Both get affected however it's always bank 1 more than 2.

Being that the pressures are more than enough at the sender I dont suspect Oil PSI is an issue but more that the pressures are not entering the VTC correctly. After changing VTC solenoids and sensors with working one's I've removed this possibility.

Another possibility is the VTC filters, possibility these could be clogged more towards Bank 1 vtc which I believe is why I see erratic pressures, as VTC solenoids demand operation, the pressure to them is not there (leak or filter clog) which causes them to act up,

The ability to monitor VTC oil pressure would help me out more and be able to further improve the diagnosis.

What I don't like that you did is putting silicone on the galley gaskets and the fasteners that hold them down. By putting silicone on the fasteners this may have caused them to not go in all the way which could cause them to back out and cause the erratic oil psi that you mention. Also, by putting silicone on the gaskets a piece of silicone could have finally broken off and is partially clogging the passage that feeds oil to the camshaft phasers and solenoids.

Looks like you may have to tear down the timing components for inspection. Sometimes reading live data isn't enough.

I was wondering if that was you (from myg37) over here. Possibly the phaser IS the problem? I wonder if Soho has run into this?

From what I've reading around the Z forums do not reuse the OE hardware as they back out, even starting to happen on the 2013+!!!
