Hi all....picking up omega tomorrow after head gasket replacement....the guy said that it had blown on all 4 cyls and so much water had gone into the sump that the oil was like grease....he has flushed the system twice and is ok,but has said that maybe it would be a good idea to do it again,,,,so any ideas what is the best product for me to buy to flush it out before putting genuine oil and filter on it again...thanks.

Blown on all 4? Find that difficult to believe. 

Before getting anything, strip it down and see what's what

Strip what down? Head gasket has just been replaced

Wynns engine flush would be my first choice, alternatively drop the oil once a week for a month, fitting a new filter every time

[flyer 0712]

As you say,,,head gasket already done....he has saved the gasket to show me tomorrow,i have known this mechanic many years and trust him......although the day before i took the car to him it did produce white smoke from the exhaust...on the morning of taking the car to him on the 4/5 mile journey to the garage it was billowing out so much white smoke that i could not see the road behind me...the low level coolant light came on and i stopped the car and waited 30 minutes before filling the coolant bottle up..it struggled to restart but did and i manage to go the other mile to get to him,by which time the coolant had dropped below again...thus a lot of water entered the sump and exhaust which makes me think that he is correct....anyway i will let you know tomorrow once i have examined the gasket,,,,,and i will get some wynes and flush it tomorrow....thanks for the advice...

I'd strip the coil pack off, take a look inside the pots, perhaps drop the sump if it's as bad as described, see the condition of the oil. Take coolant bottle pipes off look in those, take breather system off and throttle body, look for signs of poor oil. Otherwise just chunking stuff in for sake of it. still can't see how gasket would fail on all 4 cylinders at exactly same time, one would let go first, usually the back one.

Sorry... Poor advice Tunster.

If it were me I would just do a couple of very quick oil changes to help flush any remaining crap out. The danger of using a flush is that it could dislodge something and cause more issues

[05omegav6]

Irrelevant too as garage has ALREADY fixed the head issue and changed the oil a couple of times

Buy 20litres from Vx for £40 and four filters, total cost less than £50 and change it four times in quick succession. Use Wynns if you choose to flush, but as LD says, no harm in not using it as the quick changes will have a similar result but more gently

I never advised using flush? In fact I'm against it as I suggested, see what oil is like before doing anything.

So trust the garage if you want, still worth looking at the oil first before doing anything.

another 2.2 owner throwing good money after good 
If you trust your spanner monkey then she`ll be fine. The only car I had a H/G let go on the other year was a 1.8  ecotec in her old astra. after the engine was rebuilt I was seeing oil in the water, but no water in the oil. On the the initial drive I thought the exhaust looked quite cloudy too, I assume that was moisture trapped in the Exhaust box; which spooked me a bit. Inially I was concerned about the oil & did number of oil changes in short order.
But that damn oil  was floatin about in the coolant for months after & following several coolant flushes.

Coooant takes about twenty cycles to clear the oil out

To drop the sump the oil needs draining... To check the  condition of the oil, it needs draining.

Looking inside the pots for what? The garage have just had the head off anyway
I agree it's worth checking the breathers though

[flyer 0712]

I will as suggested check all the cooling hoses and breathers and throttle body to see how they are...will also refrain from the flushing fluid as it makes sense that it may cause other problems..so will do a few quick oil changes,,as regards gone on all 4 cyls,,i think that what he said on the mobile line but it was an iffy connection,,added to that at my age my hearing may be a bit iffy as well lol...so thanks for the info and i am now off to collect my old great motor and i will update later  thanks all

You might find he said on 4 cylinder then

I'd do the first oil change and then take a view on it

[flyer 0712]

car now with me...he showed me the gasket...cyl 4 and 3 were badly blown across from the water channels,no,2,had been leaking  and you could see where it was tracking across to no.1...so yep all 4 cyls.....he said it had been done before as the gasket was not a genuine one...His theory is that also this gasket had begun to leak and someone had put engine seal into it to seal it ...and whatever it was it set like concrete on the cylinder head and around the water channels  and was a bar steward to remove,,This stuff was more than likely the problems i have had with the heating and high running temps and of course all of it makes sense now,,old oil was like treacle as he said....he actualy flushed the cooling system twice and oil and filter twice,,,I am taking it back to him in a weeks time and he will replace oil and filter again.f.o.c......I have checked water hoses and breathers and yes there is a trace of crap in there and breathers were cleaned...as for the oil all appears to be ok but i will use it to go out and about next week and keeping an eye on things as a precaution,,,,yep as someone has stated on here...another person throwing money at a desmond....but when you love omegas regardless of what size engine it is,,,why not throw cash at it,,,after all what omega could you buy for the price of a head gasket overhaul,,another one that you dont know nothing about and more cash pay out...as they say better the devil you know,,,thanks for all the help and advice and fingers crossed all is fine......happy once more..

Wynns engine flush is good , did mine on the 2.6 and it found the weak spot on the front crank seal  but at least the oil is clear as a bell after a new crank seal fitted
