Cam chain renewel axx engine code

[dazza]

If we ignore the snapping of the bolt holding the adjustor. The hardest part of this job was removing the rocker cover.

I removed it 3 times last week and took about half an hour. Things are always easier the second time around.

What is the potentially wrong with a faulty adjuster? So say you change just the chain and tensioner (both liable to snap / break) i appreciate half the battle is to eliminate the diesel noise, but could the adjuster fail?

[dazza]

I've read a few posts where people have changed the chain and tensioner and still had the diesel noise. The diesel noise did not go until they replaced the adjustor.

I took mine apart to see how it works there was no info online so couldn't really get the jist of it. The teeth did look a little worn so even a new chain may have had some movement.

Thanks for all your help I'll get it changed soon I'll make a diy for it too

So is this issue not so common on the later engines then?

had it replaced on my 07 plate after the warning light came on although I don't remember it being noisy

Replaced the chain and adjuster on the later BWA engine yesterday as per the manufactures guide http://workshop-manuals.com/volkswagen/golf-mk5/power_unit/4-cylinder_injection_engine_(2.0_l_engine_direct_injection)/engine_cylinder_head_valve_gear/valve_gear/removing_and_installing_camshaft_adjuster/

The job isn't difficult but I warn anyone thinking of doing this you need both tooling T40080 and T10252 items to be quality products as the bolt holding the chain adjuster on is "tight" and cheap tooling will result in another wise very doable DIY repair turning into a nightmare!
The replaced items cured the rattle when running at normal (90) temperature, without the camchain adjuster being fitted!

What tooling do you recommend? Did you have access to the genuine tools?

[doylebros]

I had access to the genuine tools over the weekend but that adjuster bolt is F***ing tight and you need that socket a locking tool to do the business!

[dazza]

I rounded the bolt as i did not have the T40080.

I have the T40080 and a non genuine T10252 if you want to borrow them.

[dazza]

TBH i think i would have mangled the bolt even if i had the T40080. Could have done with an extra pair of hands to hold the bit in place.

Warning light? Was it just the engine management one or is there something more specific to the timing chain/ adjuster? Thanks.

Ok thanks, being a bit naive would a 36" breaker bar do it?

Thanks Dazza I had seen your generous offers to others so had you in part of the plan 
I'm due a cambelt so probably get that done then consider doing the chain and tensioner in a few months 

Was just a bit concerned about pantneted part after what vrs Alex said about them but you managed and GTI-Andy using your tools 

[doylebros]

I know of one person who used a Laser locking tool and the locking pins just bent apart when undoing the adjuster bolt!
I also know of one person who used a Proto tool (Poly-head 10 socket) that just twisted and delayed the job by a day until TPS got him the correct socket!

On a similar note did you see this post

That's a real bill for job which is quite enjoyable with the correct tools at a fraction of the dealer costs!

The sealey locking tool seems ok. It's been used a couple of times now.



That does seem a lot for a timing chain and water pump.
