Hi all,

 

Skoda 2.0 tdi Laurin and Klement DSG 2016 plate.

 

Car has a small oil leak. I've put some oil leak detector in the system and taken for a long drive.

The oil leak seems to be mostly concentrated on the left side of the engine when you look at it from the outside.

I've taken the bottom tray off as well as the cover on the bottom sump. Both were drenched in oil.

When flashing the UV light the only place I can find a leak is from the area where you fill the oil in.

I've attached a picture.

My question is, is this common and if so what part do I need to replace. Is it just the oil cap?

Just feel like I'm missing something. I've checked underneath the car and can't find any leaks identified by the dye.

 

Changing the oil cap has not resolved the issue. car is still loosing oil

Silly question, you didnt spill any when adding it did you?

Got to rule the basics out first

I probably did spill some, but cleaned it out as best as possible.

I've had the check oil light come on twice in one month, each time having to be topped up.

I've left the bottom cover off, so see if I can find any oil marks on driveway. No oil marks, so i'm assuming it's loosing oil when being driven.

It's been a while.

Still have a problem with the oil leak.

I've replaced the rocker cover gasket and seals.

I've had the DPF and EGR deleted.

Car is still loosing oil.

There are no signs of oil leak on the driveway, so can only assume it's happening whilst it's being driven.

Car isn't burning any oil, no signs of it on the exhaust.

Is there anything else I can check before I throw in the towel.

 

A myriad of possibles, particularly as not much info known about the car's history, servicing, mileage etc which may be relevant.

 

If the leak-check is the green dye shown in the picture, was that spilled as well, or is it what has accumulated after running the engine?

 

First off, I'd run the engine with the filler cap removed to see if you've got pulsating pressure puffing out, this may indicate worn rings or badly seated valves.

If there's no leaks then it must be burning it, probably turbo goosed. Could be other things like rings and valve guides/seals though.

Mileage is currently 150,000

I've only owned the car for a few months 

I've given it a service using genuine service parts from TPS.

The dye is from after running the car. 

Can anyone suggest a good mechanic. I'm based in Leicester,don't mind travelling.

The car runs fine, no smoke, no loss of power.

I've had a mechanic have a look at it who said the oils seems to be leaking towards the back of the engine and he suggested replacing the rocker cover gasket,which hasn't solved the problem.
