Creamy residue in intercooler pipe

[JMW]

Hi, second question of the night, when I was looking at the FBH I took off the intercooler pipe to get better access to the fuel pipe.

There was a creamy residue in the silicone hose pipe, similar to what I’ve had in the past when I had a head gasket failure. I have the EGR bypass.

Has anyone had this? Know what the cause is? Know how to fix it?

Should I be concerned or is it just moisture mixing with the oil residue I the intercooler?

Many thanks

I have never seen this in any of our diesels - we have 4 in the family. :}

Have you been doing lots of short trips, maybe from cold ?

I usually only drive a few miles to work which isn't long enough to get warmed up, but the car does get long trips like yesterday and today with a 300 mile round trip. It was very wet yesterday when we drove through the rain and there were some significant puddles and road spray.

Im replacing the intercooler pipe this week so should I flush the intercooler out with degreaser to clear out any oil residue and or fit the special air intake deflector?

You should fit the air deflector plate as it was developed to protect the MAF sensor - unless you are running a MAFless remap of course. :}

I’ve got a maf and no remap, just ordered two from DMGRS ( one for Dad as well) so will get it fitted as soon as I can.

Thanks
