Hi
Has anyone fitted one of these oil catch tanks jobbies on a Def90 with Disco 200Tdi engine and if so:-

Are they worth the £25ish price?

Is there any real benefit?

Any down sides?

Cheers
Kev
 
erm, you know it's a diesel, right?
why shouldnt it burn the oil? Do you want to push your mpg downwards, or clog your cyclone breather?


and now: STOP FIDDLING WITH A PERFECTLY GOOD ENGINE!

if you've got a problem loosing oil, try getting a new cyclone breather or look elsewhere (rear main seal, piston rings, wife)



PS: Benefit? No
 
im sure someone on here had one fitted, Crowman? pos?
Def seen it done tho.
But as Philvy says if its bad enough to need one then the problem lays elsewhere
 
Drill a hole in the top of the chassis, stick your breather pipe in there


No rotten chassis, job done ;) :D


No, there is no point whatsoever having a can unless you don't like a little oil on the drive, if that's the case, sell the Landy :lol:
 
I installed one and for good reason too. My 200tdi doesn't have much wear and as such there is very little blow-by but I had been suffering from condensation forming in the cyclone breather in the colder weather when my engine hadn't warmed up properly on shorter runs and I found that this water started to collect in the air intake pipes. Not wanting it to be drawn into the engine, I decided to fit a catch tank which would collect it and store it until it needed to be drained. My 200tdi engine doesnt like to warm up much (I have a knackered radiator, no fan and a perfectly working thermostat) and even if I'm sitting at 65-70 on the motorway it doesn't get much past 1/4 on the gauge. If anyone is going to ask... no, it doesn't use any coolant either!

It does the job well and it keeps the intercooler oil free too if you do have blow-by problems / excess crank case pressure which will in effect, ensure that your intercooler is always working at its best.

Yep I fitted one - works a treat and although I understand if you need one then your lump is very worn my 200tdi in every other way is A1 - so I am happy with this mod.

Its the extra ZF resevoir.

Thanks to all for the input.

I will have a good clean of all pipe work and cyclone and see how bad it is before deciding.

Cyclone breather is pennies.
And a catch tank you can get from an empty bottle (make hole, put tube from cyclone breather in, catches about 90%. Had to do it on my 2.25 petrol, but there was no cyclone breather...)
Save the 25 quid on beer

Your an engineer by trade I guess?
 
Anyway...

If you want to see how much comes out of your cyclone breather, take an empty EP90 bottle, put a tube in it through the cap (down to the bottom), connect to the cyclone breather output. If the cyclone breather was connected somewhere, cut a hole in the top of the bottle and put a tube in (not much, about half an inch) and connect.

tadaa, about two feet of tube and an empty EP90 bottle later your very own FREE oil catcher, that can easily be emptied (that's why you put the inlet through the cap...)
Before use put some oil in it, so that the input hose is submerged (so that the oil vapour can condensate better.

Why did you want to spend 25 quid? You're not even sure yet if it's the cyclone breathers fault, and if the oil catch runs full it might give you backpressure on the cyclone breather, rendering it useless (depends on oil catcher, but...)


Get yourself a beer and find the fault, stop trying to get rid of the symptoms.
:beer2:
I'd give you a hand, but it's a long drive from Krautland

I tried extending my breather pipe to go in to the chassis, almost to where the rear suspension is mounted. Had to pull it off again when i found the whole cab filling with smoke when I stopped at some traffic lights!

In theory, you'll fail an MoT with an oil catch tank.

Slightly wrong there,
IF your engine is vented straight to atmosphere then you are in the wrong.

IF you engine oil breather ( or what ever you want to call it) is fed to a catch can which is then vented then you are GOOD.

All the lines to the intakes are for is to keep it simple for them, Going to a catch can aids engine breathing as it gets better cleaner air in the intake.

What the specs say is an engine should digest its own fluids,
