HELP with timing issue...
Greetings all!
I need some help with my 2006 XC90 AWD 2.5.
Had an oil leak that came from the exhaust cam seal, so I decided to also replace the timing belt, the water pump, tensioner, idler, crank seal and the intake cam seal while I had everything apart.
I made very articulate cam sprocket paint marks in order to put everything back exactly as I took it apart, meaning that (outside of using the factory timing marks) I even made a secondary set of paint marks on the timing belt with the corresponding sprocket teeth, and the crankshaft teeth to insure proper placement and I then transferred those paint marks over to the new belt.
I also made reference marks behind each sprocket for the back and forth play that the VVT had before I loosened them to ensure I replaced the cam sprockets in the exact same positions.
I used a rear cam lock-down tool.
Everything seemed perfect when putting everything together.
I viewed pretty much every YouTube video on the subject that I could find before I took on this task, but not once did I see anything about performing a VVT preload sequence (going 90 degrees past the timing mark and then returning).
I can only guess that this is my problem as I am getting a P0016 code even though it's purring like a kitten.
I moved the exhaust sprocket one tooth to the left, and then got a P0017 code, which I thought a bit strange, so I put it back where it belonged, and we're back to the P0016 code.
I'm trying to be as articulate as I can here.
One YouTuber recommended on his video to loosen the three 8mm sprocket locking bolts and adjust the sprocket travel, which I played with on the exhaust sprocket positions with no avail, and I'm just about to play with the intake positioning after the engine cools down a bit(I'm marking where the original settings were just in case).
So...knowing that I didn't do the VVT preload sequence before I removed the belt and the camshaft sprockets, what would you experts out there suggest I do to remedy my situation?
I really appreciate any advice you can offer.
