Hi, wondering if anyone can help with the following :

Vogue 3.6 142,000 miles, changed oil on Sunday and all seemed fine. Been checking the levels a couple of times a day all week and seemed to be just below the max mark this morning.
Driving home at about 60mph got a juddering for about 4 seconds and then all seemed fine, rev counter didn't fluctuate and drove the next ten miles home with no issue. As soon as I pulled up at home the oil lamp lit up and when I checked the oil it seemed to be half way down the dipstick so obviously lost oil on the way home. No oil on the driveway at home so seems to have happened all of a sudden.

Would low oil cause the juddering ? I'm going to get under the car tomorrow when I have time to see if one of the sump plugs have come loose, I did tighten them both up on Sunday but the rear one is a pain to get to but I'm sure it was tight enough. Only other thing I can think of is the new filter wasn't seated correctly and the oil has been leaking down the engine onto the undertray and hanging there, will soon know tomorrow when I removed the tray !

any thoughts or anyone had anything similar ?

Cheers in advance

If the engine was running it won’t have been an oil level warning that came on, it would have been the oil pressure warning light.

I’ve not got a huge amount of experience with the 3.6 but check in the intercooler pipework and the air box for any signs of oil as they do seem to suffer from turbo failure.

If the oil pressure is low then do not run the car as it will do damage. 2002 4.6 Vogue SE - Alveston Red with Lightstone Leather

Thanks for that, yes it was the oil pressure warning light that came on when I parked up yesterday. Will be checking the car out later this morning when I have time. Seems to be a bit of a coincidence I changed the oil a few days ago and all of a sudden this problem has arisen. Hopefully it’s nothing more serious than the sump plugs are leaking !

Correct oil filter? Fitted correctly? Just thinkin out loud that’s all🤭 2012 Orkney Grey Westminster 4.4TDV8 with Ivory interior.........nice!

I don't know whether the oil filter housing on 3.6 is the same as the 4.4, but if you've just changed your filter try removing the filter and have a look in the housing to see if the drain back valve is still on it's post.

Thanks for the replies, I’ve just checked the airbox and no sign of any oil. I’m about to check the intercooler pipes but noticed the jubilee clips aren’t opening so that’s the next problem to work around when I’ve had a cuppa.

It is indeed the correct filter, I’m going to take it out and check to see if it was seated correctly when I fitted it. Checked the oil this morning and it looks like it’s half way up which means about 4 to 5 litres are missing and can’t imagine that much is sitting in the engine under tray.

Anyone know if oil going through the turbos would cause the juddering I got yesterday ?

If the engine / turbo's have ingested 5L of oil I think you would have noticed the smoke cloud behind you. 2012 TDV8 Vogue (L322)

I think I’ve found the problem, took out the oil filter and I’m afraid I’ve been an idiot ! The oil filter piece at the bottom that sticks out is bent, I haven’t seated the filter correctly and compressed it ! The filter wasn’t dripping in oil as I would have expected but oil had been through it.

This means that the juddering could have been a bearing grabbing due to insufficient oil. Hence the sump should be removed to check and probably replace all the bearings and hopefully the crank journals are OK.

Where has all the oil gone? Any shiny fragments in the filter?

Tough one to call. I feel your pain.

The difference between max and min on the dipstick is normally around a litre. It should tell you in the handbook to be sure.

Hopefully fitting a new filter and setting the oil level again will see you all good and no damage has been done.

Thanks and fingers crossed youre right David, no shiny bits in the filter I'm glad to say. Will be renewing the filter and topping up the oil on Saturday and take it from there. There was some oil inside the turbo intercooler pipes as seen on the blue rubber glove photo but nothing excessive and had to wipe my fingers all around to pick up what is showing in the photo.

I agree, and meant to add that too - drain the oil.

It is a bit odd that the revs didn't fluctuate, which would indicate the engine didn't stall or slow.

Is it a lot of work to remove the sump?
