Ok, having tried to start my 59 plate gti on Tuesday morning to no avail, I have just confirmed that there is no compression 😭
I am guessing chain tensioner as they are so common and had no issues with car up until this point.
As a mechanic and capable of stripping and rebuilding the engine I was wondering if anyone has done this? Is it possible or is it scrap? I ask because reading thru this post, all the warranty ones were new engine, no rebuild?? Thanks

It all depends what has happened and bent / damaged. It may only need valve and head work but may need more. Pulling the head would be imo the first task to investigate.

I agree with snoopy. Head off first. It was cheaper to replace engines under warranty than mess about with rebuilds. From what I have read most of those with damage have got away with valve and head work. There are some videos on U-tube about engine rebuilds etc.

Having watched a few videos and a bit of my own knowledge I am going to pull the head over the weekend. I have already decided that if it's coming off it's having 16 new valves. I've priced chain parts thru tos with a new chain cover, going to get gaskets etc thru a local factors to try and cut some costs.
Just a couple of questions for those who have done them, there are 3 chains but nobody replaces oil pump chain? Does it need doing or is there no stress like the other 2?
Whilst head is off is there anything worth doing? Modification wise??

HI All

Only just found out about this timing chain issue.  Put a deposit down on a Mk6 GTI 61 plate (50k mileage) yesterday.  Registered October 2011.

Not sure if the Timing chain/tensioner etc has ever been changed, havent looked at the service history yet.

Any advice on whether this age Mk6 might be ok etc etc?  Seeing conflicting reports as the when VW changed/revised this?

In simple terms if it has the latest/last version of the timing chain then its not likely to fail like the original?

Could negotiate the price down further to account for this work to be done if not.

Coming from a M4 Gti but this issue on the Mk6 looks catastrophic if not dealt with sensibly.


Thanks

Hi drokkeh,

Post #4 (at the bottom) gives details of the dates that the revised tensioners were introduced. If the car you’re getting hasn’t had the tensioner changed, then it won’t have the latest version (May 2012).
2016 Pocket Rocket Polo GTI 5dr manual, Blue Silk, Jacara tartan seats, Sports Performance Kit, Climate Control, Convenience Pack, Parking Pack, VW Motorsport Alloys in anthracite.
Gone but not forgotten; 2011 Golf GTD; 5dr Carbon Grey, Grey Jacara tartan seats, 18" VW Rotary alloys in Anthracite, Bi-xenons, Parking Sensors, RCD510+Dynaudio, Luxury Pack.

Hi.  Ok.  Thanks for this.  So in simple terms if you have the May 2012 part (3rd and last revision) all is good?  Regardless whether it is factory fitted or retro fitted by dealer/VW specialist.

This is all I need to know really.

I know its hard to say 'yes, if you have the latest revision, the issue will NOT happen'  - But its much less likely i guess?

Just want to put my mind at rest for the sake of £300 - £400 replacement early on.

Not sure what your mileage is? If over 75k then worth checking the timing chain and guides if replacing the tensioner as labour costs not much more, mainly parts costs. See #608 in this thread for method of checking timing chain stretch - uses VCDS and measuring block 93 and potential costs for doing the lot.

Thanks.  The car I am buying is a 61 plate.  Mileage 50k.
