Engine seems to knock real bad after engine gets hot like its out of time if unplug the vvt solenoids it runs great something is telling them to adjust timing to much.
Was thinking air mass meter ordered any other ideas if doesn't work.
Oh when it came in it had a cam code and i found cam sensor was broken it had new installed found part of other in engine. Phaser was damaged replaced it. still did it after.
Then I pulled front of engine apart found chain tensioner leaking oil around gasket and then we decided to re time chain. If still doing it.Will let know after air mass meter.

PS no codes at this time

Air Mass Meter didn't fix it.
Do to original Cam sensor being broken we suspect something electrical.
We moved on to testing cam sensor signal was none that we could see if scaled it down we could see something but doesn't look like anything we need. So we are looking at diagrams to figure out. Any ideas post ***Possibly PCM ?*** or other component.

 

We believe oil pressure is low to vct system because every time vct system goes to retard timing it doesn't recover after it lets oil out of system it should fill up fast it doesn't.
P0345 keeps coming on. which doesn't mean cam sensor problem it just sees something is wrong I took it as a circuit electrical problem but don't think it is.
Then we decided to change oil and look in pan.
Very shocked to find a large peace of metal in pan now we need to pull pan.

Its funny it doesn't knock at all until timing retards if you rev up engine and let off then it retards timing dumps oil out and cams then float all over the place. And only Hot
Starting to think oil pump came apart but gauge says its ok.

 

When you get the pan off take a good look at the thrust bearings on the crankshaft. They have had issues with them.

 

Found them in pan. ? what kind of damage does it usually do.

 

It sends metal throughout the engine. Pull a few rod caps and main caps, a few cam caps, and the chain tensioners and see how bad the damage is. If the cam caps are scored you need new heads. It may be engine time depending on the extent of the damage.

 

After you Mic the Crankshaft journals you can decide the extent of the repair needed. If it tossed the Main thrust bearing also look to the rods and piston/pins for damage from crank movement excessive thrust. I would guess overhaul/crate motor would be a smart career move.
