Thread: Massive oil leak - Disco II TD5

My guess would be the rubber o ring on the oil filter , seen it happen and done it myself on the TD5 just because of where its located behind the turbo so very hard to see if its sealed correctly. When mine leaked the old o ring remained behind when i removed the old filter so the oil ****ed out between the 2 o rings , was very hard to see it without having a close look.

The only other major oil leak I had was when the gasket behind the centrifugal oil filter housing blew out.

Good luck finding it.

Cheers Ean

As alluded to by Ean, check there is only one O ring on the filter.

Buy yourself an inspection camera ... https://m.ebay.com.au/sch/i.html?_fr...pection+camera then clean and let it sit running whilst you inspect it with the camera, it may take an hour of running before you see a leak, but inspection camera will make it much easier ... make sure you get one with LED lights ... if you don't have an android phone or tablet and can't borrow one, get a normal USB connection (take out otg from the search) and then a laptop and off you go.

Let's hope it's not the rear crankshaft oil seal which means gearbox off, also check the oil pipe to the vacuum pump on the alternator

A bit odd that a Landy specialist mechanic can't diagnose a large oil leak, which begs the question , is he aware there are 2 different size cam cover gaskets ?
there is also a cam plug at the back of the head
oil leaks other than mentioned that can become large are turbo return pipe gasket , centrifugal oil filter return pipe to sump gaskets, also an 0 ring on the same housing which can become flat over the years.

degrease completely then run engine to find the leak bearing in mind the fan can spread oil back and gravity helps it down

lots of people have hubby's , they're common ..........disco twos are getting rarer .............people want to scrap them

If everithing is covered with oil than it will be hard to identify the leak. Try to clean as much as possible and at least identify if it comes from the left or right, up or down.
I also have some leak (minor but want to solve) and after many cleanings I could sort out that it comes from the back side of the cover gasket.

try and catch some on a clean surface and at least see what colour/consistancy it is,,, just from that pic it looks clear enough to be fuel..

I would have to agree with pedro that from the first picture looks a lot like diesel drop on the bottom of the plate and the paint lifting like it is also suggests to me I'd be looking at the fuel system .
