Hi Ben.

There was a lot of mayo in the filler neck but I presumed its because the car has only been run on the drive and not taken for a good run out. Check the oil on the dipstick and make sure thats clear.

Have you taken it out for a good run yet? Its hard to say because your HBV is leaking water badly which could account for the water loss and the car hasn't been driven for a while just started and run on the drive which could be the reason for the mayo.

Sorry to sound thick, but what is "HBV"?

i think heater bypass valve maybe?

H.B.V, heater bypass valve. situated at back of engine,shape like the star-ship "Enterprise".Transfers coolant to and from heater matrix. HTH :y

when i get out of traffic and get up to about 40mph it starts going back down but the whole time you are stopped its in the red and also if u go below 30-40mph it starts overheating too?

Thats not good. Do the cooling fans kick in?

yeah i heard them come on

I would guess at Head gasket.Leaking HBV has allowed coolant to get low and the engine has overheated, blowing the gasket(s).

Post by: benjy44 on 16 February 2011, 17:36:48

yeah thats what i was thinking i dont think its worth having it done if it is that.how much do u think it would cost to have head gaskets done?

Title: Re: think my omega is broke possible hg?

Several OOF mechanics within striking distance. Might not cost as much as you think. ;)
