I used to have a coolant leak but it somehow fixed itself one day.  Right after that miracle I developed a small oil leak (looking like doctor claw rollin' down the street), so I replaced the rocker gaskets (big up to the "Administrator" for that knowledge) and no more oil leak!  I then changed the upper and lower plenum seals and the timing belt.  After all this TLC my car still wont cut me a break; the coolant light comes on even when I put coolant.  When I check the resevour there isn't any coolant left.  It isn't leaking out anywhere that I can notice, so where is all the coolant going?

Thanks in advance to anyone who can answer this one!

Hmm, could do with a bit more info really. What was
the history of the leak? How much have you put in?
What car/engine is it? Presume a V?
Usually some evidence of a leak can be seen outside
the engine,but it can be difficult to pin down, if youve
Just changed the coolant then it can take a while to
 bleed itself of air.
  the HBV can be most dramatic and easy to
trace if its wet. Start there. If not your usually into
The V of the engine and if you have just been in there
And not seen  any evidence around the oil cooler cover
Plate and t stat housing then your round the back
of the block for the coolant pipe or core plugs at  back
Of cylinder head on pass side. If its none of those i
 would be looking for head gaskit(Rare) signs, mayo on
dipstick, sludge up the breather system up to the
Plenum air inlet. But if you just done the cam covers
You should have done the breathers as well and
Presumeably would have seen any sludge?
So as you can see a bit more info will help. Profile as
Said on your other post. Hope helps.

Thanks, I thought I saw a wet spot on the ground this morning, not sure if it's me though cause nuff people park on the street.  By the way, what is that beautifull machine you have in your profile pic?

I've replenished the reservoir 3 times now in the past couple days, and I mix it 50/50 like they ask-yet there is still some magical force exporting my goods to an unknown region of my engine.

It is very probable that it is the Heater Bypass Valve (HBV) very common problem on the Omega. There is a how to somewhere on the forum.

Yes there is. It's about 5 psi that the water system pressurises to.

The amount of water you are losing fits exactly with my experience of a HBV. I never saw any water but did smell it when parking up. If this is your problem then it is probably dumping on the distributor pack. This can wreck it PDQ.
