Cam adjuster/phaser wear

[RBS]

INA is an official VW suplier so you’re good on parts there

Taking a day off and attacking this job tomorrow.

Found another workshop manual stating the 20Nm plus 45 degrees, so doing this as it is the most common result I have found.  I will then check the torque after

[MKVASMR]

That’s the correct torque spec

Well I started this today at 8am and finished about 6 hours later.

Not that bad a job if your methodical about it. Took the usual apart once at TDC to get to the cam adjuster. Marked the camshaft also to see any movement



 I attacked the bolt with the cordless Impact and the socket was getting quite warm with no give on the bolt.... so let it cool before I then used a breaker bar and it then gave way and eased off without issue THANK GOD!!!  The theory of the impact was to help break the metal bond, and it appears to have worked for me.



The cam adjuster had wear as expected and it was a little difficult to jig the casing off, but replaced the rings anyway



Tensioners were the same



Put the new INA parts on and the old chain had a little play (this job was done 7 years ago when I got the car)

Marked it up and fitted it all.



 The welded up cam tool kit off Ebay worked a treat

Cleaned up the mating surfaces for the new gaskets





Turned the engine over a couple of times.....then put it all back together and warmed up the car.

The cam case with the rings glided on with ease

Before the phaser was -3 degrees




And now after it had warmed up, it's at 0 degrees, so very happy.




No more minor rattle i was tuning into between 1k and 2k revs, so very happy

The only concern I have is the cam adjustment intake bank 1.

Is this high. AC is on so it raises the rpm from 740ish to 800ish, otherwise the car drives great and is very responsive.

Congratulations on a hard job well done.

Thanks

Congrats!

Mine was +3 to +6 before and now, after, it sits at 0 to -3. I could be wrong but if I remember correctly, my bank 1 spec is 28 while actual is 27.5 most of the time at idle

[mjmallia]

They are 28 on the later TFSI's, but the AXX variant is 24

I am curious about the 2nd data box on group 91 being 56.1%

I suspect it is because there is some load from the aircon. I might check it with it off tomorrow

[mjmallia]

It appears to be the duty cycle of the N205. Wondering if it is faulty, but there are no error codes and car runs great.

Aight that's great, I was getting worried. I'll go for some midnight snacks in a bit and take a VVT pic for you. I've replaced my VVT control module/valve thingy. I dont remember exactly but I think it was between 37% and 57%

[mjmallia]

The VVT solenoid valve may be stuck or dirty, as all the info i see on them at idle is upto 7ish %.

I will have to take it out and give it a clean

[ZoliWorks]

Honestly at that point just replace it. I've got mine, I think INA, for 20 bucks. It's been a long time so dont quote me on the log numbers just yet xd
