oil leak 300tdi again

hi,im back yet again,
ive got an oil leak from the back of my engine.the breather pipe from the cyclone filter is soaked in oil from about 20 cm from cyclone round the back of the engine to the other end.ive stripped the pipe breather not leaking,injectors not leaking.i cant find wet oil around the back of the head gasket,the rocker gasket is new and bone dry.i cant find a hole or split in the pipe,i cleaned and dried the pipe,put it back together and about a week later exactly the same,my nice new drive is covered in black oil spots.and the oil is drippein on the the exhaust down pipe and dripping on to the ground from where the down pipe meets the middle section of the exhaust.im totally at a loss with this can anyone help me yet again.
thanks
rich

are you sure its not coming out of where the cyclone enters rocker cover ,the flange doesnt go all around cyclone spigot and they are a bugger for leakng i silicone around oring before fitting

no its definatly not coming from there ive checked all surrounding areas are dry,im just worried as its covering my down pipe

I have the same problem. found another leak on the vacuum pump. will be taking it off over weekend and putting some gasket sealant on it. Was really hard to spot. cleaned the engine bay with loads of wd 40. Then jet washed it all off. dray and clean as a whistle till I went on Motorway got home few drops on the road. From the vacuum pump. Let you know if it stops the leak.

That would be great if you would let me know john.
Cheers

I got similar problem with mine, cleaned engine bay and vacuum pump was culprit as well. Just gotta save the pennies for new one, till then it's parked on old carpet on the drive to save the gravel :L
