LC5F's Graphite Blue GTI - Pilgrimage to Caffeine & Machine
LC5F:
Thanks @Pudding - Thanks for confirming the crank being slightly out, was starting to think the cam may have twisted - This vid is terrifying:
Yes - I think something must have had gone awry with the chain install.
Every film on YT the guy tweaks the intake cam and with a bit of faf on it goes with just the one person - I had to turn both cams with my wife installing the ring.
Oh well - at least it's not the belt again and the head is now firmly attached to something - not floating around on my kitchen island!
pudding:
I had to read the comments on that vid to understand what was going on, but crikey, that is a bit crap isn't it :surprised: Amazing these engines last as long as they do with all their common faults!
Yeah the intake cam rotates a few degrees when you remove the chain because of the valve spring tension, but the cam locking tool 'catches' it. I mark the intake cam with a sharpie next to a cam cap, and I'd say it flips back (anti-clockwise) approx 4-5mm. That is what needs tweaking back again whilst wrestling the VVT sprocket on, as you've seen in the videos :happy2:
It's definitely easier with 2 people, but doable with one person. Good job your missus was around to assist! Mine would never tear herself away from Love island to help with car jobs :grin:
LC5F:
Thanks @Pudding - it wasn't easy getting the help, I had to coerce - getting the head out/off the kitchen/island was the carrot!
Please can you confirm that the cam locking tool should easily slip out and that it locks the cams in TDC?
Mine were tight to take out after the cam install - and it may be the paranoia, but if its meant to be TDC I could check its not spun the cam
pudding:
:grin:
The locking tool should drop in and pop out with no resistance when it's timed correctly I'm sorry to say.
I really hope the cam hasn't spun. The video seemed to imply that only happens when you get oil starvation (blocked pick up)? Then again, didn't you have some unhappiness going on under there with the sheared off VVT locating pin?
I would suggest giving the chain timing another go and if it still doesn't line up correctly, I think it might be new exhaust cam time for you :sad1:
What a ball ache. Kudos for sticking with it :happy2:
This is what you're looking for when it's all set.
LC5F:
I was going to wait till the weekend to look into this, but the not knowing was niggling me, so dived in today.
Of all the engine dismantlement states - this is an arrangement I have not tried before:
Exhaust Cam pulley aligned with the arrow, tried 1/2 extension sits perfectly vertical between cylinders 3 & 4, plus the No.4 exhaust cam is sitting at 45 degrees - that's good, I don't think my cam has twisted - but the intake should be a mirror the angle of the exhaust lobe, but it's only 30 degrees up:
Hopefully this is it - looks like something did go wrong in the chain install, hopefully I can sort this at the weekend.
