thats interesting...that is the correct part that i recently purchased myself.
interesting to note, that they are separate systems... so it sounds like the cooler itself may be cracked and dripping into the coolant passages? it seems pretty robust.
Pm me what you need, when you need it, and I will see what I can do.
Now I am concerned... There is no water or oil mixing in the sump, nothing visible on oil cap or dip stick? I tried calling the mechanic to do a flush he says first the cooler must be changed? the car is not overheating nor engine light on or any error codes, apart from checking radiator one would never know there was a problem, the leak started the same evening when my wife checked the water levels? I am at a loss for words and feeling deflated at the prospect of something else being the problem.I have never seen an oil cooler fail like this but anythingis possible I guess. Oil in the coolant is usually a head gasket or engine block issue in some way. Unfortunately you can be a mechanic but that does not mean you're a good mechanic or good at diagnostics. Does not matter to the mechanic anyway as they're not paying the bill but getting paid.
Thank you am taking all yr advice just getting through to the mechanics are a challenge they always insist it be done their way 😡.The car needs to be flushed and cleaned and pressure tested and see what happens from there.
