Agreed on the removal of the alda. Harbor Freight has a "Service Wrench" set in metric that will work well at loosening the alda. That intake does not need to come off either. It's a snug fit but can be done. I've done it several times. Also look at ALL the pressure lines and crossover valve for clogs. Most people forget that a good portion of the sludge is from the oil being drawn into the turbo from the valve cover vent and blown through the intake. This will thicken as it gets colder.
