from that it does sound like an old (fixed / non existant) problem  :y

Enjoy the car  8-)

Where did you have this work done out of interest?

There are no signs of oil on the dipstick - the oil looks clean?

No water on the dipstick on the other hand is a good sign ;)

Yeah, I wouldn't worry about it. Iron engine blocks go rusty with time. Doesn't mean imminent failure. It's highly unlikely that one head would start weeping water, let alone both on a V6 at the same time and if it's dry now there's no problem!

I'd have no hesitation driving it to Spain from what I've heard. I might be tempted to take a spare crank sensor and HBV just in case!

As said above by other members....

But the most important question is: are you actually loosing coolant? If the coolant level does not drop over time, then no leak.....

To sum up:

Mayo on filler cap, but no mayo on dipstick - normal.

Mayo on dipstick, and/or oil in coolant - oil cooler. A bit costly to fix, but not terminal.

No mayo on dipstick, no oil in coolant, but coolant level dropping - leak, most likely HBV, but could be elsewhere. HBV will loose coolant faster when A/C is on.

No coolant level drop, no leak... neither form HBV, head gaskets, or other place.

Head gasket fault as said very rare on Omega V6, in most cases can be verified at MOT station by checking for exhaust gasses in header tank.

HTH.

Yes guys - it was me on Ebay. Sorry for pulling the auction early but on finding this site I had a glimmer of hope in saving the money I have invested in the car. Ebay would'nt let me finish the auction early so I had to do the "sell" the car to the highest bidder senario. I know this is not good Ebay ethics but I was desperate.

You'll prob remember from the Ebay description that I had purchased the car to drive to Spain. I had the Cam Belts done just as a precaution as I do not know when they had last been done. As you know I spent a good bit of money on the car since purchasing it i.e. Belts, Brakes all round, Tyre + 12 months MOT. Just under £500 which I have the receipt for.

I had hoped that maybe it wasn't as bad as first thought after looking through the forum but I just can't be sure and not being a mechanic I don't think I want to risk it driving to Spain.

When the mechanic did the belts he noticed rust around the front of the head - which lead him to suspect the head gaskets were on there way out. I know people have said that is more likely to be the heater bypass valve but that is located at the back of the engine right?

Anyway - if anyone wants to put me out of my misery I would take £500 for the car and cut my loses. I don't know what else to do.  :'(
I am interested in purchasing (I was bidding on Fleabay) I have PMd my tel No ;)

Another thought:  did the mechanic replace the belt AND the tensioners or just the belt.  If he did the latter then it is not good news.  Typically the tensioners fail and take the belt out with them.  Vx specify that belt AND tensioner must be replaced at 40k miles.
