[Steve s reg omega]

Hi all. I haven't used the Omega for a couple of months now as she stared to loose oil and water. A few people have looked and it appears one (or both) of the head gaskets have gone. She still starts and drives perfectly but I've been told is a horrible job to undertake    so I may need to move the car on  Does any one have any suggestions?

[Webby the Bear]

Doubt it TBH 

How was the HG diagnosis achieved?

[dbug]

Unusual (but not unknown) for 2.5V6 head gaskets to go

As said HG is unlikely on these engines and if so it is normally just coolant weeping down the sides of the block.  The fact it is loosing oil too makes me suspect the oil cooler.  less of a pig of a job.  The hard part is the repeated flushing

What colour is the coolant?

I am around the corner from you and, luckily for you, on leave in the UK for a couple of weeks.

Hi guys, a few mechanics had looked at the car and we got to the HG as the oil filler cap had the cream in it and the water dripping from the exhaust!! due to the previous heating issues it made a lot of sense.

Where round the corner

Crap diagnosis so far!

Short runs or poor oil easily create Mayo under the filler cap. V6 are quite steamy anyway. Water out the exhaust is normal.

How much water is it loosing? Checked HBV (see guides)

Oil. How much? Checked plug wells?

If that wasn't something that would affect your wallet so drastically that would be amusing!

As Tunnie says, check for oil in the plug wells and for oil in your expansion tank.

Re coolant check HBV and get system pressure tested for leaks if you can't find one there.

Are the heads off already?!!!  If so which 'mechanic' did the diagnosis?

I am literally 5mins drive away from Ash Vale, I cycle through it on my training rides

Drop me a PM and I will drop by this weekend or next week to have a look.  I have done both the oil cooler and HGs on these engines and I know what to look for

Ask the mechanics if all the breathers are clean and what oil has been used

Hi guys, thanks for all the comments. I'm going to see if I can borrow a compression tester tomorrow and have a look at the water etc to see if it tells me some more

If I were you I would take Mr Guffer up on his kind offer.

[Sir Tigger KC]

Blocked breathers, leaking cam covers and knackered HBV! 

As Doctor Opti says Guffer's your man! 

[kevinp58]

It'll be the Oil cooler  et Guffer look at it
