LC5F's Graphite Blue GTI - Pilgrimage to Caffeine & Machine
pudding:
Yeah flip the intake cam round a tooth and it should come good again :happy2:
Glad the exhaust cam isn't busted. I think that video is maybe highlighting an extreme failure. It would be far more prevalent if it was a 'common' issue.
LC5F:
Well, I was enthused by knowing I cracked on today, HPFP and VVT cover off, and then onto undoing the ring bolt:
I commented on people using grips - but it does make sense to hold the cam in TDC.
I now know where I went wrong - I did not have the cam pulley or rear cam cover with TDC mark installed - if I had them and locked the exhaust cam in position I do not think I would have gone wrong with the chain.
The so called "cam locking tool" doesn't really lock and allowed a lot of rotation of the cams, I was using the more american counting chain links - a lot of confusion out there.
Reading the guide on here and one or 2 YT vids that don't count the links I just got on with it - I did still mark the links as a final check.
Literally first go, a slight turn of the intake cam and in it went - so easy! - and the chain marks lined up:
And the cams are now like this - nice and symmetrical with a slightly higher intake:
Really chuffed - I just got stuck into getting everything back together all was good apart from the HPFP banjo bolt - I thought the threads had caught with 1/4 inch drive...decided I would try turning it with my finger tips...pulled the bit out and the banjo bolt stayed put for half a second before dropping down somewhere inaccessible - eventually found it, it took a magnet to get it out.
and the VCDS money shot:
Golf is still on the drive way, but just revving feels a lot more responsive.
All I have left is fish out some stuff I had dropped from the engine undertray, re-install the side engine cover and then drivers front wheel and I should be properly back on the road.

:congrats:
0KW phase position, top work :happy2:
Yeah that cam locking tool is hideous. If it were a normal 16V engine with 2 cambelt sprockets, you can wedge something in between them to lock them together, but nope, VW do things the hard way :grin:
Clearly the TDC accuracy isn't THAT critical if they made such a sloppy tool. Maybe the VVT tweaks itself to get it spot on but obviously it can't be a tooth off physically for that to work. I remember the R32 timing being the same. It would always be a around -3 or -4KW (instead of 0) after a new chain but it didn't affect the performance.
Blimey, even the mole grips and VVT phaser have been attacked by the famous Scottish rust :grin:
Anyway, good work and persistence, it'll be a different car to drive now :happy2:
LC5F:
@Pudding Thanks for the support - really helped work out what / where I had gone wrong.
BTW Those Vice grips are about 30 years old, just worn in!
Last bits done this morning and the Golf is feeling more itself with instant throttle response returned - all the fixes has definitely given it a bit more go, it now seems very happy to light up the front wheels.
Still feels odd (in a good way) as I had not got used to the new intercooler, sport cat downpipe, uprated ARB's and a pair of PS4's on the back - a lot to get used to.
And how does the Golf repay all this love and attention lavished on it? - intermittent Front Right ABS signal!
pudding:
No worries, glad my ramblings helped in some way :grin:
I'm now wondering if my exhaust cam has tweaked slightly (as per that video) as I can't get mine to 0KW no matter what I do :grin:
Check that again after some miles and see if it's drifted a little, but either way, you got it bang on sir and absolute confirmation your exhaust cam hasn't shifted :happy2: Annoying that it took a couple of attempts but you've gained a ton of knowledge during the journey :happy2:
Oh dear, out with VCDS again! Hopefully just an unhappy wheel sensor! Your car is certainly making you work hard for it's affections :grin:
BTW, I like the MAF sensor position on your intake kit. They've moved it away from the turbulence of the turbo wheel, nice effort, no other intake maker considers that :happy2: What are long term trims like with that kit? Block 032 in VCDS. It looks like a good one to me.
