When i turn the heater on i find i dont get the proper hot heat unless i rev the the engine a bit ??? Could that be a sign of the hbv on its way out ? No leaks from it though :-\

Normal for a cold engine, but most likely is a lazy thermostat...

Lazy/damaged water pump?
May I ask about a post some time back on the topic of heaters, i.e. now to re-set the flaps by pressing console buttons, please? I cannot remember the details and I know that Al knows EVERYTHING!

I hope not Ron , new water pump fitted a few months ago with cam belt :o

Have you got the auxiliary pump mounted near the air filter/ coolant reservoir? I think when (not if) that gives up the ghost it acts as a restriction in the heater flow.

That was my thinking too, "Boatboy"; you just beat me to it! That, or some other constriction in the system that yields to the greater water pressure at higher revs.
A quick check would be to by-pass that aux. pump?

Good point ill have a look 8) Wonder how much a new one of those is from mr stealer ::)

You could just take it apart and remove the impellor, or revert to standard plumbing.
Of course, you then wont be able to keep warm while waiting at a level crossing though.

I'll probably just rip it out and do without it .

Hi - I suffered similar woes and replaced the t'stat, HBV and the Coolant Reservoir Cap - however the main culprit turned out to be a misfitted gasket on the EGR mounting - see http://www.omegaowners.com/forum/index.php?topic=133208.msg1706876#msg1706876
Either way the cost of the bits is low - the hassle factor is astronomical!!

It does indeed have that pump fitted so at some point it will need looking at but its gone rather cold outside ::) I guess some suitable plumbing will be required to bypass .
