Hi all, was carrying out timing chain replacement on my eddy over the weekend, of course the adjuster bolt rounded (correct tool used) so had to try and force a bigger torx into the head with no joy, so I’m going to have to drill it out…. I marked the cams and they moved slightly as did the cambelt markings but all relative to the same amount. I put it all back together and now the chain is very noisy (wasn’t before) no problems with the way the engine runs…
I’m therefore not using it and going to sort it before I use it again…
Is my chain noisy as I’ve been hammering a bigger torx bit in and shwarf has possible gotten into the adjuster oil feed holes or is it possible that the timing has jumped, despite all the marks moving relative to one another…I’m going to change the adjuster anyway as piece of mind (anybody have the part number?)
Cheers

You most probably snapped one of the plastic rings on the cam chain cover, on refitting.

A break in one of the rings or excessive wear on the adjuster, reduces the oil pressure to the tensioner........then creates the rattle
-
Thanks for the reply, I was thinking it might be due to a lack of oil and the chain or tensioner being noisy so this reassures me a bit, is there any tips to putting the cover back on without breaking the rings?
Was hoping I can get it off, get the bolt out, fit new chain, tensioner and adjuster and fingers crossed be back to where I was prior to messing just with a new chain 🤞🏻
-
All depends on your cam adjuster, and sounds like it has wear. Mine does too, so on re-insertion the rings can catch on the grooves that have worn in......it should be smooth, so extra care required or replacement cam adjuster to resolve it properly.
Looking into replacing mine and that will also increase the oil pressure to the cam adjuster and tensioner, instead of it bleeding off making a rattle at certain rpm or idle.

Yeah just saw this on AKS website, new adjuster for me I think whilst
I’m messing in there
-
Yeah, just ordered an INA one as the genuine VW version is £700 all in from TPS......I just can not make myself spend that anymore (age of car etc) even if it is mint like mine.
-
By any chance is that the INA one on eBay from auto-parts1_666? I saw this one but then saw it was coming from China so I questioned the reliability of it being an INA?
-
No. Bought mine from AutoDoc so I know it will be genuine. They have a good deal on it at £128
-
This one and ordered elring gaskets etc at the same time

Yeah good shout mate, INA good quality think I’ll do the same, you ordered new oil rings? Rang VW earlier and they didn’t have a clue what I was on about
-
Yes, elring ones also from AutoDoc. Used them already when I fixed a broken ring due to the adjuster groove wear.........fit perfectly

What a hero you are, cheers for the help mate good luck with yours 👍🏻

Thanks

Recently done this job on mine as no history of it ever being done.
Adjuster bolt held up ok but broke the lugs off the sealey cam locking tool instead. I recommend an assistant counterholding the camshaft as you undo the bolt, eases the stress on the locking tool and helps keep everything lined up.
I bought all genuine parts and can confirm the genuine tensioner is INA
I replaced the oil control rings, even though I was really careful on removal of the old ones I only managed to save 1 of the 3. They were not broken beforehand but had become really brittle probably due to baking in hot oil over time.
Good luck :happy2:
-
Hi mate, yeah I welded around the lobes on my locking tool to reenforce it,unfortunately never got to finding out if it was good enough as the bolt rounded 😂 thank you for confirming the genuine part being INA, awaiting my INA one to come so I can then drill the bolt out, replace adjuster and rings again and fingers crossed be job done 👌🏻 it’s all fun and games isn’t it 😂
-
Thanks. Ordered the cam locking tool and had planned to weld the lobes also when it comes........seems to be common practice :happy2:
-
My bolt rounded too :sad1:
The other way to deal with this is time up the engine, remove the cambelt and then loosen the cam carrier so the camshaft can be moved. This'll release the chain.

Don't remind me of that trauma :grin: I suffered the rattle for over a year before I finally found the cause!
Gotta say though, the engine ran superb with a VVT repair kit afterwards. Get it from the Skoda dealer though as it's cheaper. You get a new chain cover housing, VVT adjuster and bolts and gaskets etc for around £500. Stiffly priced I know, but at the time VW wanted £800 for the same stuff.
-
There is also another way to loosen the bolt!
You get yourselve a second hand camchain cover, cut half of it off so you can see what you’re
doin. Bolt it back on but put the bit on the bolt first then a short extention and a breaker bar.
That worked fine :happy2:
I’ll post Some pics of it when the uploader here works again!?!
I can’t upload pics for some reson?

Succes😎👊🏻
Hope this helps you guys.
And it’s better to have a help when losening the bolt! Someone to counterhold the camshaft sprocket.
Enjoy 😉

I have a similar question - had a top end rebuild after chain snapped - had repair done at garage then got a p0011 code - took it back and theyre saying the O ring has broken (appears they didnt replace it when repairing and said it needed a cam shaft adjuster)
So ive got the adjuster but they are saying it needs a new housing now.
they also state that the o rings I have are metal and not plastic like the ones ive seen for sale - AXX engine - can someone confirm if this sounds right or not? thanks
dont want to replace the cam chain housing if its not needed
-
Original rings were metal, but then VW changed them to plastic as they were damaging the cam adjuster/phaser.
-
Any idea if they already updated it in 2006 on the BWA or does it still have metal rings? I didn't know as much about the car back when I had mine done and never even thought about checking it. I figure if it's metal, there's no reason to replace them, if the VVT itself was replaced.
-
I am guessing about 2007 they made the change, bur seen 2008 S3's and even a 2012 Mk6 R with grooved adjusters.
