Thread: Oil weeping from air intake hose

if the oil around the intercooler plumbing, my guess is that you have a leak at the turbo. Are you blowing blue smoke?
I'm surprised your LR dealer didn't find this.

Thanks Owl,
I was a bit worried it may have been the Turbo. I have not noticed smoke of any colour.
Would the high oil level be a contributor?
To give the dealer there due, the service was done end of Jan and the oil weep looks quite recent and also looks quite clean (not sooty), I was cleaning it up after we had just returned from our shakedown cruise with the Disco and van, just a short 700k trip to Castlemaine and back over 5 days, when I noticed it. This trip was to test the Disco's capabilities, as this is the frst LR I have owned as well as get our checklists in order, as we are resuming vanning after a break of 35 years. The Disco performed very well, to me it accelerates well and pulls well. I did not molly coddle it and kept it at 100kph on the open road. The trip up with a head wind returned 16.5 l/100k and the return trip 14.5 l/100k. the van is 2.7 tonne GTM.

Could the oil be from the rocker cover vent/blowback? wonder if you can fit a pro vent to one of these?

Hi

If the oil is inside of your turbo to interclloer hose keep a eye on it as the hose can delaminate on the inside there is a heavier duty one avalible. Or if the budget allowes you could go for a silicone hose. Some oil is fairly normal.

Mine had a small leak where the hose meets the bottom of th intercooler. Just normal oil contamination from the turbo. REmoved cleaned and tightened up prperly, no issues since.

Hi Morrie, Coincidental timing .... I had my intake hose off on the weekend and found a nice pool of oil in the bottom of the intake hose and a leak in the intercooler at the base of the hose connection. Fortunately i have already arranged for an intercooler upgrade from allisport in the UK including silicone hoses. Aswell as {following recommendation from BAS} installing EGR blanks. I should have it all installed by next week {time permitting}. You may want to consider something similar if the oil leak continues , Just a thought mate.
happy travels

Hi there,
I've had two D3s and both have had a slight weep around the bottom intercooler hose connection. I haven't associated this with any over filling or turbo problem. I did the same as mentioned earlier and cleaned the connection and put a better quality clamp on, no problem since.
Synthetic oil when warm is very searching and will find the smallest leak path. Especially when in a vapour (ish) form. Me I'm not overly concerned.
