Bora TDI Head Gasket
Just bought a TDI Bora (90bhp non PD) which turns out has knackered head gasket - or so i think  I didn't notice the symptoms until a few
days after I had bought it annoyingly.
The only symptom is blowing its water out, no mixing, dont think any oil loss, temp gets to 90c and stays there rock solid. Not been able to do any
compression test yet however - not got the tool for a diesel! It looses about a header tanks worth of water every 60miles or so. To me it just smacks
of head gasket failure and am gearing up to do the job this weekend. But am I being too hasty - could it be anything else? I've already changed
the pressure cap as these seem to go sometimes apparently.
If I do go ahead and do the gasket what special tools am I likely to need (manual not turned up yet). I guess there is likely to be a few pulley
alignment tools. Other than that the job doesn't seem too hard as access looks good. There seem to be very few people on the net who have
documented any DIY attempt at the job.
Any help appreciated.

Given there's no other symptoms I'd try a new presure cap first, unless you're getting presure almost as soon as it's been
started.
It's worth putting one on after a h/gasket replacement anyway so your not loosing anything.
OPPS... should read more carefully!

If you email me the engine code, year and model I'll see if I can print off the relevant pages from the workshop manual for you.

Is it worth getting a "sniff test" done to see if any exhaust gas has got into the coolant...at least you would know for sure before
diving in.

It is only blowing water out of the pressure relief on the header tank - I know as I'm collecting it and putting it back in!

Check for a cracked head, more common with VWs than you would think, and much more expensive to fix.
DO NOT PUT ON KNOB OR BOLLOCKS!
