Hi guys, i had my oil cooler replaced (at some great expense) see older posts. Was just wondering how long it takes for all the oil to get out of the coolant system. I needed the cooler replaced as it had failed and sucked up lots of oil into the coolant system and ended up with custard in the expansion tank.
The garage have said the engine may need flushing thru a couple of times to clear it all.
I have had it done once but still have oil in the coolant.
Have checked oil levels in sump and they are fine as had oil change and new filter when cooler was done, so its not sucking up oil still.
Have spoken to a friend who is a mechanic and he said it would take a while.
Was just wanodering what you guys and gals think.
Its a 51 plated 2.6 v6 auto on 70k.
thanks guys all comments welcome...

add.... Have had the heads checked just to be safe.

It all depends how long the car was driven with a faulty oil cooler, if its caught soon enough then there's less flushing. I think its the worse part of the job and can take many many flushes to get the coolant clear. Buy a few bottles of Forte coolant flush to help shift it

with this problem would you also get get a oily/coolant smell through the heater, just asking because my oilcooler gasket was replaced coolant looks ok but smell coming through vents  will add no coolant/oil leaks
