Well I disconnected it and so far so good thanks for all the
help.
So im planning to make a oil catch can Im thinking of bunging up the breather pipe on the inlet, and i have a half L aluminium bottle and put a small tap on the bottom filling the bottle with that cleaning wire wool type stuff putting a bit of pipe halfway down the bottle to connect the breather pipe to and for the top filter insted of buying one of those K+N type small filters do you think it would be ok to sandwich a peice of cotton between 2 peices of aluminium mesh the same size and attach it to the top of the bottle ?
Some of you say that the inlet can get coked up from the EGR valve is there anything that can clean this without dismantling it, On petrol cars I used to remove the maf and spray throttle body cleaner when the engine was running and it realy made a big diffrence, Iv seen similar things you can supposadly use on diesels like that 10K boost stuff from halfords and this carbon blaster
http://www.dieselbob.co.uk/fueladditives.shtml but there both about £20.
Has anyone ever tryed using these or is it even safe to use it would it maybe damage the turbo or collect in the intercooler and cause hydrolic lock or even compress in the turbo and go bang lol.
Sorry about teh awfull spelling
