BMW X5 CCV

[Sniffer]

Hi Guys

So I have a 2002 4.6IS X5 (built 05/2002) and its breaking me - a month ago I replaced some gaskets cos the CCV froze up and blew them - at this point the mechanic (a well clued up ex BMW independent who appears to be very knowledgeable) also installed an additional crancase vent that blows off if the pressure rises above 0 PSI (I hope I`m getting this right as I think thats what he said) - this would prevent the same issue from happening he reckoned

Fast forward a couple of weeks and to my horror I get all the same symptoms on my journey home (burning smell, low oil light and a warning in the cluster regarding low oil pressure) - identical to before so back to the garage and this time its a couple of hoses that have perished and subsequently burst - he replaces them and I`m good, he also informs me that he rerouted some vacuum line or something along those lines and this would help - he has done this modification before and has never had the same problem occur on the vehicles since - sounds good

So I get home tonight and I get the burning smell again (I`m tempted to throw petrol on it at this point) and while there are no warning lights this time the engine bay is once again covered in oil so I think its safe to say that the problem is along the same lines again

I love this vehicle when its running but so far its been a complete money pit and I`m genuinely driving round wondering what will fail next - Ive got a list of other things that I`ll be asking about which will need addressing but for right now this is a priority as the X5 is our only vehicle

Do BMW have a fix for this? I heard something about a heated CCV pipe - does such a thing exist for my 4.6IS? If not is it possible to make a heated version with heat trace or similar? I`m getting desperate and need a solution

Thanks in advance
