Peugeot 207 Allure Auto 1.6 VTi Petrol Oil Leak

[ecnirp98]

Hi

I bought a Peugeot 207 Allure Auto 1.6 VTi Petrol just under a year ago, its a 2011 model and has done 28,500 miles, the Car was serviced (minor) October 2017 by the local Peugeot dealer.

In recent weeks, I have noticed occasional small pools of oil when parked and marks on the road following the movement of the car when driving slowly, but was hard to say if it was the car as lots of oil marks on roads. Last week the Oil Warning message came on at startup, so I added around 1.5 litres of oil and the warning has gone off.

Last week the Car was MOT and it passed, with no advisories, I mentioned the oil leak and they said they hadn't seen any issues, so I presumed it was ok.

The last week I have noticed larger pools of oils when parked up sometimes, sometimes there is no oil, so it's really intermittent, one thing I have noticed is that it seems to leak when the car is parked facing down a slope. I parked on a car park today and checked there were no oil marks where I parked, it was on a slight slope, when I came back after 30 minutes there was a patch of oil and it had started to run in a line down the slope, so defo looks like it's leaking oil. I drive to work daily, around 250 miles per week and the car is performing ok.

Just wondering if anyone has any ideas what could be causing this? I've read a few posts about Head Gaskets going on the 1.4 model, but mine is 1.6. The car is out of warranty as it's 7 years old, but the mileage is very low for it's age, I am considering taking the car to a garage, am I best with the Peugeot dealer? as quite a few people are reporting Head Gasket is a known issue, so Peugeot have repaired for free? but I know dealers will be allot more expensive if I have to pay.

Thanks for any advice.

It shouldn't be making a huge puddle if the issue is head gasket. There isn't much oil accumulated in the head during operation, and then it quickly drains into the sump once the engine is off. Check your coolant, if you have no mayo you should be fine.

Sounds like a sump gasket issue potentially. Maybe when you park on a slope the oil just reaches the edge of the sump and starts to weep out?

Thanks, I did put quite abit of oil in it as I was 200 miles from home when I got the oil warning message, so I quickly bought 4L of oil and put about 1.5-2 litres in, I kept checking starting the car until the oil warning message stopped appearing and it said oil ok, even though the dipstick showed it looked ok, so maybe I put abit too much in?

When you say check coolent for Mayo, do you mean in the coolent bottle? (sorry don't know much about engines!)

Your description of this leak suggests a rusted sump to me.

Corrosion (from the outside of course) can form pin holes that don't leak consistently.

Thanks, booked it in at my local garage to take a look, hopefully nothing too expensive!

The garage did ask if I had been using air conn allot, I don't usually use it, but the last few weeks in UK have been really warm, so it has been on constantly, so could be related to air con, I presumed Oil as I did top it up last week when I got the oil warning light.

It's the 1.4 8v that Peugeot were paying for out of warranty head gasket failures on.

Clearly you're experiencing a leak but it's also worth noting that your engine will use a lot of oil and will likely need topping up between services.

Hm, Not quite sure how air con can be directly related to oil leaking. The only thing I can imagine is if they think your crank front end oil seal is buggered, and the extra loading that the aircon is inducing onto the accessory belt is causing it to overload the seal, hence making it leak. But that doesn't seem very likely.

Or they think you're a fool and the puddle under your car is condensed water from the aircon and not oil...
