Slight Oil Leaks

[Erik]

I was looking around the engine compartment of my recently bought Galaxy. I have noticed black oil deposits on a pipe and valve thingy that sit just behind the camshaft cover. This same pipe seems to lead down to a kind of heat exchanger underneath the radiator and there is some oil here too. Does anybody have an idea what may be causing this? There are no issues with the cars performance but could it be the turbo? Edited November 6, 2010 by Erik

Hi there

What your describing sounds like the EGR valve (exhaust gas recirculation) as its name suggests recirculates a certain amount of burnt exhaust gas which is drawn back in to the cylinders to be burnt again, supposed to reduce emissions.

 

The heat exchanger (turbo intercooler) cools the charged air as cool air is much denser which leads to more air being compressed before fuel is injected result more power.

 

As to the oil deposits, there will be a certain amount of oil mist in the large air pipe/intercooler and EGR valve as some will be mist from crankcase fumes, although excess oil laying in intercooler could be leaky turbo seals or excess crankcase pressure.

 

Having said all that if cars running OK with no loss of power or smoky exhaust leave it be, my only concern would be the oil around the intercooler area is it from the fins of the cooler or the pipe connections, if it's the fins the cooler is leaking and will need replacing.

 

Hope thats of help to you :)

Your reply was a great help. The oil is coming from the connection. Do these pipes need periodic cleaning or are they designed to be maintenace free. I have also heard of cleaning the turbo. Is this something that should be done and if so are there any interval suggestions. New to Galaxy's, but keen to get to know them better. Any suggestions for a maintenance manual. Mine is a 2003 which Haynes don't seem to cater for.

 

Thanks for any replies.

Hi again

Pipes only really need cleaning if they are removed to access other components.

Turbo is designed to be maintenance free, if it's running OK leave it alone as it's quite involved and awkward, to remove/replace, the EGR valve could benefit with cleaning this can get clogged with oily soot which restricts the air flow.

 

No Haynes manual made for MK2 so the TIS manual on CD is an option this is what Ford use, although it can be a bit hit & miss sometimes although it's better than nothing.

 

Also important is the need to change oil and filters regularly. 10.000mls recommended by Ford using SAE 5W-40 for PD engines
