Oil leaking from intercooler hose

Hi all,

Just a quick question regarding the attached pic...

I popped my head under the Landy and noticed that there was fair bit of engine oil which has escaped between the hose to the manifold pipework and the lower intercooler pipe, even evidence of spraying and dripping.

The hose clip was a bit loose, so I have tightened up, however the hose was still well attached.

My concern is why there was so much oil present here in the first place?

I have an allisport oil seperator on the breather and the breather pipe and air filter box have been dry of oil for quite some time and my turbo looks fine (no damage or play in the impeller whatsoever, I know they are oil cooled and have an internal seal somewhere) so i'm not sure where it has come from?

The engine (200tdi) had the head gasket done three years ago and its never felt quite right since, it burns oil and seems to lack power compared to what some say about their tdi's (even though it is tweaked up on fuel/turbo).

Should this be any cause for concern to just the result of a loose pipe?

Thanks.

Hi
I think its normal to get some oil in the hose as iv seen it loads of times. Id say the best thing to do is clean it off and see how long it takes to re-appear. If it appears quickly i would say its possibly a turbo issue, somebody may correct me on this though

Take the pipe off your turbo ( not the inlet ) and see how much oil is is in there , Id say the the turbo oil seals are passing oil . Id see how much oil is sat in the bottom of your intercooler too .

looks pretty normal to me. even brand new diesel vehicles end up lie that after a couple thousand miles. you always get residue from turbos

All small, turbo diesels will have oil in the intake system. contarary to popular belief it doesnt come from the turbo unless its goosed but in fact comes out of the breather pipe, so best bet would to be clean system out and stick and oil seperator in the line.

Thought he said he had an oil separater fitted?

Sorry Shifty i never read that bit!

Just looked on fleabay 82 quid! and its not a proper oil seporator which is what i was talking about i think called an oil catch tank 25 quid on e bay.
Allisport one looks like a straight copy of the std cyclone unit

Simple way to make sure you dont get too much of a build up in the bottom of the intercooler. Drill and tap a small hole (5mm or so) in the lowest point of each end tank. Fit a machine screw to each hole with a fibre washer. When you want to make sure the intercooler is clear take out each screw and go for a drive around the block to get the turbo boosting. It will blow out any oil in the intercooler which will have settled out to the lowest point. Obviously while you are doing this you will be down on engine power but it wont do any harm. Put the screws back in to seal the intercooler and Rob's your mother's brother. My intercooler has drain holes for that very reason but everytime I've had a look things have been nice and dry with no sign of oil.
