Hi all. I have a 2011 4.4 tdv8.
Had the turbos replaced 18 months ago
Egr blanked and mapped out also.
A Few months ago i was getting regular low oil warnings, took it back to the turbo guys who checked their work and said all was ok with the turbo operation.
One day i pulled on to the driveway and oil poured over the now full undertray.
I still using it and set about the strip down.
Front end all stripped i removed the crank pulley to find the crank seal was 10mm out of the casing!
Whilst i had it all apart i replaced all the pulleys, alternator, even a new aircon condenser. A new crankseal fitted cleanly and correctly, new bolt for the pulley and put it all back together.
I also replaced the small rubber bung inside the oil filter housing as i saw it was missing.
Engine all buttoned up i started the car and it sounded great, smooth idle, no smoke and no leaks.
Reversed off the drive coasted down the hill i live on turned around and accelerated back up to the house pulled on the driveway and oil was pouring onto the driveway again!!
I mean pouring not a drip.
I can only assume the crank oil seal has blown out again.
Im so fed up after all that work.
So i ask if anyone has heard of this happening before and what is the cause?
Pressure is obviously building up internally but I can't think what else to look for to fix it?
Please help if you have any experience in this issue, many thanks.

See my post on the other thread about crank oil seals Craggers.

Good luck !
