I've noticed once i take my car out for a drive and park it in my driveway i have a few oil drips on the ground? I looked and it is coming from the Tial external wastegate? The car didn't have a dump tube when i bought it, been meaning to get one put on but oil is being sprayed out of the wastegate on to my engine and dripping on the ground. Not sure whats causing the oil to come out of there?

 

well it doesn't operate with a oil lubrication system so your oil is most likely coming from the engine itself.

 

PCV in place?

 

I would first check your oil feed line for your turbo if it is not physically coming from inside the wastegate. If the oil is coming from the mouth of the wastegate, you might have an internal oil leak or turbo seal failure but then you would be seeing quite a bit of smoke out of your exhaust to go along with the drips.

Sounds like you might have a leak in your feed line for the turbo and its getting the wastegate soaked in oil just from it being below that point.

 

+1 on the turbo leak, I had a garret that would leak when the car was cold, once the turbo heated and took up some tolerance on the seal it was fine, no smoke.
