Emulsified oil in intake pipe

[andyisinwilts]

Hi all,

I have just returned from a 3000 mile round trip down through France & spain over the last 2 weeks with an average of 37.5 mpg over the whole trip, the van picks up well & had some good climbs, so power is there.

However coming back last night from the tunnel there was a hell of a lot of rain/spray on way home. (As a note we had 2 days of heavy rain in France on way down, but had 30 + degrees down in spain)

I go to check van this morning, oil & coolant all spot on, oil cap clear, but I do check to pipe into the inlet manifold for oil & clean it, however this morning there is a bit of moisture ( clear water not coolant) & emulsified oil, I have cleaned as much as I can & started up & all seems normal.

Has anyone else had this or could it be a blown hose or the intercooler allowing a bit of rain water in?

The cali is a 180 103k, oil is changed every 5k & uses about 100ml- 250ml between changes. No coolant loss at all & oil temp max seen is 113 when climbing long hills under power at motorway speed, but drops & sits at 95 - 100 all the rest of the time, so not worried about the dreaded egr cooler, which by the way is still the original item with no prefix!

Any help gratefully received, or am I going to have to get the bumper off & remove the intercooler to check/clean?

Cheers all

Exactly which vehicle/year have you got?
You mention 180 in your post and your Avatar says T7 4Motion.
It is not uncommon to get some emulsified oil in the dipstick tube on a Transporter when there is a significant change in ambient temperature and humidity because of its length and it’s position.
More often reported on the T6 which has a longer oil dipstick tube
