Oil and filter was changed and I am using 5w40 Platinum oil which is castrol, we buy it in 205L drums at work and it's been on this since the rebuild. Just checked the oil level before I drive it to work and it is a little high on the dipstick, well it was a rush job after work last night! I will drain some out this morning and get it on tohe level this could be the problem. As for the hanger I have noticed the rose joint neaest the turbo is very close and only has to twist 2mm and is then touching the machined washers that sit in the vracket on the turbo. so I will try and space this out so when it twists it won't touch the washers.
