Losing Hope! Too many problems.

[Donfero]

I have changed 2 turbos, 1 DV, boost leak tested multiple times and still have an under boost issue! And to top it off now I have a misfire issue and oil on my spark plugs, cylinder 3 the most. I have changed the valve cover gasket but still having the oil issue.
Can a bad boost pressure sensor cause under boost?

I had oil on my plugs and similar to what you said and it was an injector failure have you had them tested at all?

Ricky, how can injectors cause oil on plugs?

I was about to tear down the plugs.

Lol sorry, as far as the misfire issue though id still definitely check the injectors and if you say its number 3 might be worth chucking an injector in it i had no boost and really bad running issues.
