oil and diesel leak from 200tdi

[kizz81]

hello,
i have had this problem before but never found the cause. it only happens when using motoway for decent length of time,
the pictures explain them selves....





please bear in mind that the engine cannot be worn inside badly because it has only done 20,000 miles at the most, and the filler cap is a good tight fit

need as many sugestions as possible as i need to get it sorted for a 200 mile trip on saturday

cheers kieran

oil issue
make sure the breather systyem is all nice and clean
derv wise could be the spill off rail weaping

Wash out the crankcase breather with petrol or paraffin and all the pipes,looks like your getting excess crankcase pressure,on the diesel side try checking the little plastic pipes that run between each injector for holes and while youre at it tigten the nuts up on top of the injectors(not too far though) :D

cheers for the reply, i will try these things tomorrow morning and see if it makes a differance then report back,

thanks

Be really careful not to shear the bolts on the return pipes  :-'

That black plastic thing at the left of the picture is an oil seperator, the hose goes to the air filter.
The seperator needs a good clean regularly, and the hose looks like it might be shot, allowing it to collapse under the suction of the turbo.
I tend not to reconnect them at the air filter end after cleaning as a head-gasket failure will dump the engine oil into the intake and may cause a destructive runaway! Just make sure you cap the stub on the air filter if you do the same.

neil,
i have oil running through that "worn pipe" is that not good?

cheers kieran

[extreme90]

a little oil is normal
oil running out is not so good

[kizz81]

what are the chances that after 20,000miles the head gasket would be wearing out?

chers kieran

[L90OOK]

To be honest very little unless you have done something like overheat the engine?
Why do you suspect the head gasket?

[kizz81]

alot of people i have talked to have said likly to be a head gasket, im just trying to wliminate that as a possibility but if i end up taking off the head i would change it any way

OIl getting blasted out of that pipe is caused by piston ring blow-by.  It's worse at motorway speeds becuase the negine is running hard for a long time.

I fitted a catch tank to that pipe and blocked it off at the turbo, all seems well so far.

[kizz81]

how serious is a piston ring blow? :shock:

[Range Rover Blues]

It's present in all engines, even new ones, but gets worse as the engine wears and the rings weaken too with time.  A significant blow or chuffing might indicate a cracked ring but given the mileage you have on that engine I'd stop worrying until it blows up.

I'm told a cracked ring will make a ticking noise on a TDi anyway, so I think yours is just tired.  If it goes ok then leave well alone, think about a thicker oil, like the Lucas stuff I use, as good oil will help a little.

If you're at the pub ask me about the catch tank ;)

To be honest it looks like the breather is blocked.  If you look at your second picture the rocker cover gasket has leaked too.
All diesels breath a bit so don't  worry to much about that.
As said, give the plastic breather pot & pipe a good clean & go from there.  The turbo shouldn't affect the pipe as long as the intake/filter isn't blocked.
