10 points to you my friend

The problem with bugs like this is that you get 20 different ideas on what it is, and you end up whit the car in 1000 peases.
My solution to the problem... i am in the prosess of doing some upgrades including the turbo, so i`l use the car until it start using oil then change the turbo

And tnx for all the replys, you people make this forum great
