Thanks! Glad that's the one to get at from underneath I was looking from the top last night and it would be be really tight without pulling the intakes off. Where is the connector on the O2 sensor pig tail? Can you get to it from below or from on top? I notice that yours is a 2004 which does not have DPF's. I hope I can still get access as readily as you did with the DPF in place.

I might do the intakes anyway. I checked them last night and they are a little coked up especially right behind the throttle body where there's a 1/2" mountain of carbon built up. The hoses from the intercooler are also quite cruddy with thick oily residue. I think I need to clean the whole lot and then get a tune to back off the EGR.

The EGR system reduction/Delete will only do so much, the main culprit to all the oily sludge is the PCV system. Stop those oil vapours getting into the inlet manifold and most if not all your issues will be gone.

Makes sense. Any recommendations? Is there a 'catch can' or something that can be put in the PCV system?

Mike
A few options there. Depending on how much work you want to do.
Yes ultimate is 2 catch cans 1 for each side. V10 problem is very little room to put it but to the inventive I m sure not a big issue. ProVent make some really nice catch cans.

or simple option

Swap PCV valves from LH to RH etc blank off suction pipe into inlet manifold and vent your crankcase via the hose out the btm of the car.

I would still see about a EGR reduction after this.

Just doing the PCV bypass and noticed that my PCV valves are identical side to side. I can move the connections around enough to do the connections but thought it was an interesting difference between Drags build and mine.

You will notice that on the T1 the PCV holes in the valve cover are at the btm on your T2 they are at the top.

That's interesting because my body is a T1 but I guess the drivetrain is a late model year and the same as the T2.

I incorrectly assumed yours was the first of the T2 model then. But anyway yours would most likely have the BLE/BWF eng? They have a different EGR, PCV, fuel filter to the AYH/BKW eng's.
