How is the TD5 cooling pack arranged?
Is the intercooler sandwiched between the radiator and AC condenser or oil cooler?
Can you see down between them?

Yes, as you say, it's quite obvious if it's leaking,

Yes also to the 2nd question

and for the sake of accuracy and fact in place of opinion:

A smoke machine in this case would be a waste of time unless there is a large crack, as both of the failed units I found, were leaking ( as stated before ) from the seal between the tank and core which would only let go under pressure.

Yes, you can see oil stains from these spots, yes, you can also see into the gap between the rad and cooler and even if the leak was from the front of the intercooler the oil stain would be obvious.

I don't understand the reluctance to just have a look.

Smoke machines have their place, I've used them to diagnose a myriad of TD/SDV6 issues ( and if you think it's too hard to pull an intercooler on a TD5, don't think about buying and DIYing an old D3/4 RRS.

You don't even need to drop the coolant or remove the radiator to replace the intercooler if you didn't want to.

A bit feedback. Since doing the washers and seals it’s running as it should. Hooray :-). The noise that sounds like a boost leak is in fact coming from a split catalytic converter. I have to say that putting in a decat pipe is not a heap of fun.
