I have an oil leak and i have noticed it has been mentioned on the last few MOT certs.

Had a look underneath and it appears to be the sump gasket/seal

It is no higher than that and i have previously steam cleaned the engine to confirm.

It's not a bad leak but obv it needs fixed.

Is it a common place for these engines to leak?

Is there a dedicated seal/gasket or is just silicone sealant that is used?

It looks like i may get the sump off with just removing the downpipe connection? or does the Cat need removing off the turbo?

Not really. Drive shaft oil seals at higher mileage. Maybe its taken a knock?

Its a sealant rather than a gasket according to haynes. I would imagine something like this is used.

No need to remove the cat.

There is mention of the sump bolts not all being the same, so remember which when where.

It would be a good time to refill with the correct fresh oil and a new oil filter too. Total Quartz 9000 5W/40 Fully Synthetic Engine Oil. 5 litres - from here would be the recommended oil for the 16v Diesel 1.4.

And a high quality MANN filter for the 16v 1.4 diesel is also available at Here

Great thanks for the info.

Like I say it's not too bad,just a little drip off the sump bolts.

I may just leave it til I'm changing the oil

Just to update.

I removed the sump and resealed it the other day and all seems fine now.

Pretty easy job to do, Only had to remove the Cat/downpipe connection and the 2 10mm nuts holding the downpipe up to get the sump off. The sump itself required some gentle persuasion to be removed from the block.


Re sealed with some RTV silicone.

I found some RTV Silicone at eurocarparts if anyone else is looking for it.
