Known problems?

[BlueFlameHarley]

OK, so I understand the EGR cooler, oil cooler issues.
I understand the advantage of coolant by pass filter and oil by pass filter.

Someone now has mentioned about some High Pressure fittings.
What's up with these?

What other issues should I look for?

If this is already stickied somewhere, please direct me.

TIA

High pressure fittings for what ?

[Evil Eye]

I think you mean the STC fittings on the High Pressure Oil Pump. If so, yes, they can be problematic and Ford has a new design for the fitting. If you are already doing it, you may as well replace it before it becomes a problem. Additionally, you should consider an upgraded turbo drain and stainless steel HPOP screen. Since you will be calling Bulletproof, ask them about their package, which includes all of these items.
