Weird rattle! Passenger side. -6.0°KW Camshaft Block 93
OllieVRS:
I've stripped the cam bolt. Man.
First problem was the cheap Chinese cam locking tool's legs were bending.
Second problem was the bolt almost immediately stripped, despite using the correct VW bit. Resorted to bashing in a T55, also didn't work, just stripped it more.
Couple days passed, I've tried drilling the bolt to get a bolt extractor bit in, no luck as the extractor's threads don't want to catch on. And I've now get metal fillings everywhere :sad1:
.
Tomorrow I'm going to go buy a 12mm metal drill bit, then attempt to bash in a T60 as one guy has done already on YouTube. That's really my last option, I don't see how else I can do it.
Also, advice for stopping the cams from moving other than the cam locking tool? Thanks.

Don't worry about movement in the cams with the locking tool. That is intentional because you need to tweak the inlet cam anti clockwise a few degrees when fitting the new chain to get the correct tension/timing.

No, but the cam locking tool I got is so week that it's legs are getting bent out of shape as I'm trying to undo the cam bolt (as the cam is still rotating). I need another way to stop them moving.
pudding:
Even the VW tool bends, but not as much as the cheap copies though. It should hold them still enough whilst you torque up the new bolt and then just move the cams back into the position afterwards. You don't need as much force to torque the bolt as you do to remove it, so you should be OK.

Apologies for the much later than promised update, but as always with car jobs it takes waaaay longer than you expect. I also wanted to confirm the fix with a short test drive from Dublin to Belfast and back earlier today :grin:
So, I spent 13 hours drilling out the effing bolt, over a span of 2 days. Yes, 13 hours on one bolt, including three journeys to the hardware store for drill bits. Bashing in a T55/T60 didn't work, it kept slipping out, so it had to be drilled all the way to the base of the head. And the bolt's material was so hard it dulled 4/5 of the 12mm drill bits I bought.
Anyway, enough talking, here's the picture of the bolt after I was done with it (I was nearly crying tears of joy when I finally got it out, it was one of those moments):
Minimal damage to the base of VVT phaser. Disassembled and cleaned out the phaser after with brake cleaner and oiled it up.
Cam chain specs after reassembly, pretty sweet right?:
Also, I think I've solved an old mystery while doing this job. @ROH ECHT and @Clarkj93 you guys might find this interesting, since you guys commented on my post a year ago trying to help. Hopefully this gives some closure, perhaps :grin:
Have a look at my cam chain tensioner, notice something is missing?

Not sure if it's placebo, but the engine sounds quieter and I'm not even talking about the mysterious phantom rattle that started this post (which is gone now btw). Just sounds 'less angry'.
That's all. Cheers :happy2:
