Oilly puddle which greets me to my car every time I use it!

maxxpump · 24th July 2015, 13:28

The last couple of days I have come out to a puddle of oil (which smells heavily of diesel) just behind the front passenger wheel. I know the oil may be coming from another engine part and catching on the floor pan then leaking out onto the road at this point. I'm worried now as I have the MOT coming up in the next few weeks and if the job gets to expensive to get it through I may have to trade in for another 75 or

an other car like a Volvo or BMW (at a heavy loss to me and my mate). The pools are appearing over night, after every time we go out, only on the side behind the passenger side front wheel, I imagine the loss is about 200ml loss per use and I have had to top up the engine during the last two weeks. Any ideas where to look first, how to go about doing this and how serious it could be. I thought it was coming from the gear box originally (but its not red and smells of diesel), but now am thinking it could be coming out the crankshaft seal between the engine and the gearbox (does this exist and is it easy to replace if it has failed!), if the sump isn't leaking.

If I don't go out the pool doesn't appear. (So I guess it is due to parts heating up causing contraction and letting something to leak everywhere).

Any pointer would be fantastic. Hope everyone is having a stella week and hope to hear from people soon!

P.S: I have an auto box and its a connie 2001

You sure its diesel and not clutch fluid.

It an auto box, I should have said that orginally

I'm lost, does a auto need fluid for the clutch or is it all done integral to the box?

I will say that the brake light has come on in the last few weeks also. The brakes were replaced four months ago and the original sensors were used as the sensors seemed good. Could it be a brake leak? does the brake system have pressure warning or is this just a separate problem?

I have exactly the same problem with a very slow drip of diesel and it drips exactly under the fuel pump which I had replaced a while ago.

I'm going to jack the car up tomorrow morning and see what I find, but any pointers would very good in the meantime.

Reading between the lines, if you've topped up engine oil, assuming level was low, how could it be losing that quantity of brake fluid/power steering fluid or indeed transmission fluid without the fault manifesting itself by lack of sufficient fluid in one of those areas?

Diesel of course would allow loss of that quantity without showing other problems. Either way if you cannot remove the engine tray yourself to make more checks, then even the garage labour bill to do it for you will be very much less than you'll spend in changing the car for another, that like yours, may well have been traded 'as is' rather than spend time/ oir money on repairs.

Only my opinion (and may seem harsh) but if you are prepared to sell on a car in that condition rather than repair, you'll not complain I take it if you end up buying another just like it?

In the process perhaps spending more than your own car needs to fix it.

Check the underbonnet pump and pipework for leaks.

If you have an under bonnet fuel pump, as said above, check the pipe work is secure, remove the battery, and the tray on which it sits and have a very good look, it will not be engine oil as it is easily identifiable as it will be black, and anything else loosing 200ml at a time, would have manifested itself as a more noticeable problem, good luck please let us know what you find

I'd be looking at the underbonnet pump as mine is doing the same thing. It was disturbed a few months back when I changed the gearbox.

Everytime it rains I have a big pretty rainbow coming from under the car
