Hi new to all this just in a bit of bother and could do with a bit of help if any of you don’t mind please. I brought a navara d40 2015 v6 auto done 30000. But it’s got a oil leak I cleaned all the oil off so all fresh. Ran the truck on the drive for half a hour got underneath it and the oil had run round both sides of the bell housing. At first I thought it’s the crank seal but have put a cotton bud inside the cut out at the bottom of the bell housing at its dry so not the crank seal. I have had a inspection camera on top of the bell housing but can’t see nothing. I just can’t work out if it’s a rocker cover gasket, head gasket or a pipe off the bottom of the turbo. Is it a fault or anyone heard of this problem? And it isn’t the o ring on the bottom of the dip stick, already done that one haha. Thanks for having the time to read this cheers
