td4 oil filter o rings

JonFre · Jan 12, 2012

When replacing the oil filter on the td4 where do you think the O ring should go ?

When we changed the oil recently on my son's car we put the O ring in position A, yet within a few miles of motoring it had leaked enough oil to worry greenpeace. So we replaced the filter with the O ring in position B.

Was therefore surprised today when changing the filter on my td4 to find the old O ring in position A yet not a drop had leaked in 5000 miles.

Very interesting - unfortunately I can't vote twice.

Yes - you've guessed it - I have a ring in BOTH positions.

The first filter I ever bought was from BMW for a BMW 320D and it had a whole load of 'O' rings - 2 big ones - one was slightly thicker than the other, one about 25mm diameter for half-way down, a little one for the bottom of the cover shaft in your pic, and it had the copper washer for the sump drain plug as well.

I normally buy Mahle or Mann filters and they have only one large and one small O ring, plus the washer.

I'm renewing the one in position B every change, but I'm interested as to what the poll results will show.

The Haynes Manual is unclear as to A or B.

Hi i have always used B and suffered no leaks its the same setup on my transit and thats always been fine on B.

I always use B and had no problems

On the last two changes i have done. 'B'

Each oil filter i have bought hasn't had the small 'O' rings. Are these never changed? or should i look at a different make of filter that comes with them.

Cheers

Mahle filters used to have 2 big rings, a middle size, a small, and the copper drain-plug washer.

Nowadays they have the big ring, the little ring, and the copper washer. Mann filters have the same.

I must use B but like Singvogel idea of 2 so will in future use A & B

Gives me somewhere to put the old one

the copper washer is not for the freelander

Hi everyone, small at the bottom and 2p size one in the middle is a must. This will ensure your flow is right and all oil is filtering properly otherwise it is not filtering as it should.
