Hi. Just opened up my air filter to clean and it was soaked in oil. Lifted oil filler/breather to air box and it is pushing out loads of smoke. White/grey colour. Any thoughts? Looks a bit excessive to be normal fumes from the engine. Engine is a 2.5 Turbo in a 1986 90. Any thoughts welcome. Checks I could do to narrow down issue? Thanks.

Goodbye turbo......
ah good guess, rings tend to split around then - don't worry too much about it you'll get plenty more miles out of it but you will find it starts using much more oil - also be carefull not to boot it for long periods as you'll end up blowing the filler cap off and coating your engine bay with engine oil
best to keep a couple of litres of oil with you if you intend to go far
also a good time to think about putting a 200 in, which is about the same effort as doing a proper overhaul of your TD
GB stays as is now - have a read of this thread for a good idea of what to do - there's plenty more threads detailing the same process

For the time being remove the pipe that comes from the oil filler cap and goes into the air filter. This is what will cause the air filter to oil up, and possibly also one of the routes that oil will cause the engine to auto-diesel and self destruct.

Would there be any negative results to re-routing this pipe permanently to some other oil capturing container instead of the air filter?

Nope I had mine connected to an oil breather filter and resting on the inner wing. The hole left in the air filter was teped up with gaffer tape. I believe this is the standard recommendation for any vehicle with a turbo and no oil trap in the crankcase breathing system.
If the crankcase has too much oil vapour floating around this will get sucked into the turbo. And as a diesel will run on anything that burns under pressure (veg oil, diesel oil, engine oil) then the engine will start to run on it's own fumes. All later engines have an oil trap in the crankcase breather system to stop this.

The breahers are connected to the air intake to get a vacuum, to keep the pressure below ATM so it helps it breather. To be honest. I would just put a catch can on it. Although, with that be careful to empty it often!

Ummm don't think so. You want the air going into an engine way above atmos so you get more air per charged cylinder therefore more bang. Hence the Turbo and supercharger.
The crankcase breather is shoved into the air intake to burn off any noxious fumes created in the crankcase in case they build up to an explosive amount. As it was deemed nasty to just vent this to atmosphere without at least cleaning it in someway the engine designers just got it shoved through the cylinders to burn it off. Bit like the EGR in modern engines to make the stuff coming out of the exhaust just a little bit cleaner.

I dont agree - yes you do want a pressurised intake, but if you look at any turbocharged engine, (at least any land rover turbocharged engine i have seen) the breathers vent BEFORE the turbo, so they are still under some suck/vacuum.
But yes you are also right as to why they vent into the intake, to get them burned off.

Sorry, I think I mis-read/worded a bit wrong. The crankcase breater input is put into the air intake system so that the crankcase vapour is sucked out of the engine. Sadly Land Rover daftly put it into the air filter box so soaks the air filter in oil. Shoulda gone to specsavers....

I dunno for sure, but it must be better to catch it (and I don't believe there's anything in MOT 'Law' that says you can't modify the system) than let oil go into the inlet to reburn and give you negative Brownie points on the emissions bit.
My iffy 19j certainly won't have the breather connected when I go next week. Bit of kitchen roll to soak it up maybe!

i have a 1989 td and have disconnected the breather pipe from the air filter. I bought a longer piece of pipe to fit ono the breather filter and pushed it in the gap between the radiator and bodyowrk on the passenger side of the car. Seems to work fine. Oh and it passed the MOT like this.
Hope this is of help.

Seems to be a common problem with the 19j, ive got the rear rocker breather to atmos at the moment, only because the rocker cover was nacked so put a n/a one on without the breather pipe attachment.
Im going for a replacement rocker with corect connection, a catch tank between breather system and airbox and also going to breath to atmosphere if necessary using a small breather filter also available on a well known auction site eb**
Never had an oily filter and engine runs sweet at 70mph no probs, rebuilt 7yrs ago
New prob over last few days, breather cap popping out, may be seal on it or an increase in pressure in the rocker??? Anybody exp this problem???
Cheers Andy
