Hi,
I've replaced the oil breather ( seperator ) on my 55reg 3.0d today, put it all back together & engine not happy !!
Will not rev & well down on power, any ideas ?
I've took it all back apart & can see nothing wrong, no loose cables or pipes etc.
Even running the car without the air filter in makes no differance.
Any ideas ?
Phil.

Update - problem now sorted
After taking it all apart again (!) I found a vacuum pipe had come off ! It fits on the black oval canister fitted just in front of the drivers side wheel arch under the bonnet, must had knocked it when re-fitting ducting for air intake pipe. Although I must have knocked it off it had managed to jam itself under the tube it fits onto so it didn't look out of place ?
Don't know what this does but it doesn't half effect engine power !!
Engine now back to normal, 3 hours to do what should have took less than an hour ;-(

Glad all sorted..........frustrating taking longer but I expect this to be the case if occasionaly doing things others do for a living all day long.

that black tube sounds like the vacuum pipe which controls the turbo waste gate. with it off- the turbo would never build up any pressure - hence down on power!
had this pipe perish on my old 330d - thought the turbo must have failed but found split in pipe, renewed it and good to go!
glad you got it sorted.

Nice one Phil glad your sorted now ...i bet that was a relief

Always good doing jobs yourself and although threw you a little at least you got it sorted.

Might look for this on my E70 35d - assuming the dea;er doesn't find a cure for my car's symptoms.

Was a bit worried for a while
It's unbelievable what problems something so seemingly trivial can do.
I'm suprised the pipe is not fitted with a clamp or tie-wrap of some sort, in fact I may just do that.
Job that should have taken less than an hour ended up taking 3 hours
All good in the end though & hopefully the post may be some help to others if same happens to them.
Thanks again, Phil.
