Thanks guys for all your replys.....let me start by saying that I am an ex mecahnic by trade, so I could actually do it myself. My main problem is manily time - as I have been off the tools for around 10 years, I'd be extremely cautious in pulling it all apart, then any head issues will take time, then reassembly.....it will probably end up takeing a couple of months, which Im sure you can appreciate, it not desirable.
WIth regards to the CO test - yes, that will definately happen before I continue with the job, however the writing is on the wall, because the car idles roughly, spits traces of water out the exhaust, and consumes a lot of water from the radiator - no external leaks apparent....so its HOPEFULLY just the head gasket, but as previously suggested by some of you guys, there could be a number of other causes....PLease all keep you fingers crossed for me !
Heres my baby...when she was running ! sob sob
