If you`re still getting sludge in the coolant bottle it`s either more flushing or the replacement oil cooler is failing, and just because the rad has been subject to some flushings doesn`t necessarily mean it hasn`t still got a blockage

i`ll give it some more flushing, the oil cooler was brand new part from vauxhall and i was lead to believe they are now stainless steel to stop the corrosion, my reason behind the head gasket failure is the fact the engine seized because it was stood for so long and the water that had collected internaly.
would a compression test piont me in the right dirrection?

not with %100 certainty
 
 
but may give valuable info..

In this particular case compression test in my view is useless.

With it you can see what compression particular cylinder makes, but you have a case of mixed oil and coolant. If compression is escaping from the chamber into water your coolant hoses will be very hard when running, if it escapes to oil you will have excessive oil usage and black smoke. As you dont have these things its safe to assume its not that problem. If your gasket indeed failed, than it is mixing oil and coolant between their supply lines between block and heads.

Iirc its almost impossible for oil/coolant to mix due to H/G failure on a v6.

Indeed I am not familiar with v6 gasket oil/water supplies layout. Never had that kind of troubles on v6.

no smoke at all from exhaust although there is a smell , not a rich running smell.
no water in oil.
from feedback i`m getting i think i need to try and flush water system out again and if that doesnt work i`ll have to take heads off because i`m out of ideas.

I've had a head gasket failure and your symptoms sound more like a blocked radiator. I would investigate the blocked radiator route first, as it is much cheaper and easier to fix. If you know somebody with an IR camera this can pick out cold spots on a radiator.

Another idea in that direction - have you flushed heater matrix separately? It might still be clogged up. I would personally remove rad , put it on the ground with outlets up and fill it with a mixture of degreaser and water and let it stay for the night.  Would probably use warm water as well. With heater matrix do the following - isolate it and get 2 pipes ( inlet and outlet from heater matrix) in more accessible place. Go do Asda petrol station ( or wherever there is self service car wash) and run hot water under pressure for 5-10 minutes depending on what is coming out of the matrix.

the rad as been off twice, filled it with gunk degreaser, that route as been done,but if the sludge is still in the system it will need doing again, i think the heater matrix sounds likes an idea i`ll try.

Have you checked the waterpump is properly working and intact?

brand new vauxhall water pump with new gasket and new bolts, tested while hoses were off and it kicked out loads of water so yep thats working fine.
