Cam chain bolt drilling!

csrigo:
Hi folks looking for some tips.

Need to drill the cam adjuster bolt out absolute nightmare. I will cover the oil feed holes prior to drilling however has anybody else done this with success and no dramas?

What method did you use and what size/type of drill bits also...cobalt im assuming?

Any help or tips would be appreciated.

Cheers

Send dazza (Admin) a message he done the job and a thread all about it.

Yeah cobalt drills and just work up in size gradually.  If you drill dead centre, you should have no issues.

If you cheese it up completely, budget for a new a VVT adjuster.  £400ish from VW, or a chance a £100 Chinesium one from ebay.

csrigo:
Cheers folks got it out no problem thankfully. Cars still stripped under the bonnet so will rebuild through lockdown.

Cheers

Nice one, I did this on mine too, once I got up to a 10mm hole I gave it a tap with an impact driver and it came straight out,
