Mr. Ken

Hello, I am working on my 2011 Cayenne s. Just pulled the valve covers to look at the cams.

Watching many videos, and reading on forums, when timing is perfect the two holes on top of the camshaft are facing up and you can bolt in the timing tool properly.

The question I have is do I have to crank the flywheel so the holes line up and you can stick a tool in there - prior to using the camshaft tool?

I guess I’m just wondering if I I don’t do anything to the engine and take the valve covers off. Should I see perfect timing, the holes straight up right away?

attached are pics after I took cover off. Cams are not lined up




Thanks for any comments a little difficult to explain

Why? What are you trying to accomplish?

Yes, if you got extremely lucky and happened to stop the engine at exactly cyl1 TDC on compression.

Mr. Ken

I have code 17, 344
replaced Cps and crank sensor.
On bank 2 found the plastic / Deloran bits piled up along top of chain.
Not wanting to do a timing chain job - I wanted to see if I could adjust timing to see if I could get by for a while

Getting to the point of having off the valve covers is probably the most involved part of the process; it would be a real shame to not go the next bit to replace the timing chain guides at this point!

What code do you have. P0344?

So if that's the case, you changed both sensors and then see cocaine piled up along the top of the chain. If it were me, I whiff that stuff up then start on the guides. Don't put that thing back together half fixed. Do it right the first time and make a DIY for your fellow members. May the power be with ya!

It's interesting that the S model V8s are the ones with this issue; high mileage turbos don't seem to eat up their chain guides like the Ss. How many miles are on your S?

The large U-shaped chain guide that breaks apart is $98.14 from the dealer. With the timing chain cover installed, you can't see is how much of your timing chain guide has broken off; if you just "whiff up" the chipped off pieces (how many did you have?), it will keep chipping and create the error again, which would completely waste the time and $$ you have already put into this.

There's a DIY post here, and I'm sure you can get good guidance as you tackle this!

Plus, you still have to check your oil pan for the rest of the pieces.

Mr. Ken

Thanks for the feedback. My cayenne has 183k miles and runs pretty dang well. Would love to keep it for another 5 years.

Mr. Ken

Alright gonna go for it. I have a alldata subscription for one month. Thanks for the help as I have questions -

first question - removal of radiator fan. I’ve disconnected everything - what do you do to the side tabs so you can free it and lift it out? I tried a use a screwdriver to pry one and the tab broke

update - ok I found there were some black flat springs that you push in order to free the fan assembly.

Mr. Ken

I removed the intake and a saw that some wiring has been chewed maybe. Will need to do some minor wiring repair.

in the valley there was some almost shredded insulation - not sure if that was brought in by a rodent or if there is some insulation in the valley.

im replacing the starter while in there - was not too difficult to remove.

Anything else I should replaced or look at while in there?

Intake valves are very carboned. I will use Berryman’s to soak and pick at it to remove some deposits.

RAudi Driver

I wouldn't touch the carbon unless you plan on totally removing it from the back of the valves. If you have a Harbor Frieght near you, go get the tank and some walnut shells and do it the correct way. You will also need one of these.
