Hello,

Last week I noticed that my car was leaving some drips on the drive-way. Not much, but noticeable. I put some white paper on card beneath the car overnight to see how much it leaked in one night and what the colour of the liquid was. Overnight it probably only leaked a few drips and the colour of the liquid was brownish.

Today I jacked up my car and put it on some stand and checked the underside of the engine. The drips were located directly beneath the engine, the centre of the car, between the front wheels.

I could only really see some fresh drips from underneath, as you can see in pictures 1 and 2. I could not locate the source of the leak.

I lowered my car and looked beneath the hood. I removed the plastic engine guards. I could locate the leak to the an area at the rear passenger side of the engine, I think, but still could not locate the source.

I thought initially that it could be coming out of the actual fuel top up pipe and dripping down. But I'm unsure.

In picture 3, the red circle is where I think the leak is coming from. The yellow circle indicates a piece of metal with a hole in, there is another hole diagonally opposite to this hole, along the plane of that piece of metal (See picture 4). The leak looks to be coming from this hole... But I have a feeling that it may just be pooling in this hole. If you look at picture 5, you can see the liquid pooling at the bottom rear, passenger side of the engine.

I'm at a loss as to what to do or how to locate it further, apart from taking it to a garage.

I would be greatly appreciative of any help.

Thank you for reading,

Mark

I would start with a new cam cover gasket. That looks like an AVU engine and the gasket was revised in 2011 to part number 06B 103 483 G.

Hey man, thank you for the reply. I'll check out that gasket. It's quite difficult to see around that area and I hate taking my car to the garage because I'm always worried about getting ripped off.

If you find a VAG specialist, there are a couple near you including one which is very tuning oriented which is often a good sign as it means they are enthusiasts of the brand and keen to do a good job. It is very unlikely you would get ripped off as it is so easy to get bad reviews on the internet... it has happened to me a few times and a couple by people who have never been near my garage!

Hey, Crasher.

Thanks for the tip. My friend works at an actual VW garage but he advised me to find an independent garage as it'd be cheaper. So, it's possible to find an independent garage that specials in VWs? Is that would you mean. Also, how would I know if they are tuning oriented? That may seem like a dumb question but I really don't know a lot about this stuff.

Thanks again, man.

If you Google “VAG specialist Fleetwood” you get a few results including one who is a “tuner” which modifies VAG products for increased performance and like myself is an APR remapping dealer and sells performance parts so again like myself, these people are probably VAG group enthusiasts and so more interested in the job than a regular garage... not a cast iron rule but hopeful. As I said it is very unlikely you will be “ripped off” as it is a pretty risky strategy in these tinterweb days BUT that doesn’t mean it will be cheap as the gasket is £30 and will take a couple of hours to install so expect to pay around £200. The other worry with a car of this age is in doing the job you will come across many heat, oil and age damaged plastic and rubber parts which can simply drop to bits when you touch them. An example is the air intake pipe which costs £64.76 AND can be the reason for the oil leak in your pictures.

That's amazing information. Thank you very much for it.

Another point to make is that my car had been sitting off the road for over a year until recently. I thought it may be something to do with dried out seals or washers or something becoming cracked and therefore leaking.

I should update my location too, I'm currently in Liverpool. I'll do a search around my area as you suggested. I have the Haynes manual too so I might try and do it myself just to have a look. I have a whole week off next week so I could dedicate a day to having a look around. Unless that's a big no-no.

As VAG engines of its time go, it is a fairly simple thing to work on, a 10mm 1/4” drive deep reach socket will be your most used tool. As I said, beware anything made of plastic, well Nylon 66 in most cases, great when it’s new but when 20 years old can just fall to pieces.
