What's this?



I'm trying to remove some parts of the EGR system for off-road use, and I have read here about people needing to block off a port on the block, but I assumed they meant the one on the head. But now I noticed this contraption. Is that an unneeded part of the EGR system, or does it need to stay?

That looks like the EGR cooler.

Looks to be the EGR cooler; if you block off the EGR valve, the cooler is no longer needed. Just remove it and all the hoses and plumbing attached to it. Plug the coolant feed line on the head and replace the "Y" with a straight connector where it connects back into the hose on the top of the engine. Either replace the FCV with a Weeks101 kit or remove the butterfly plate in the FCV simply by removing two screws that hold it to the cross shaft!

Picture of all the junk EGR parts removed:

Sorry...I hit send too soon.

This thing is on them passenger side, behind the water pump. I already took off something on the driver side that looks more like what you have in your pile above.

Is this an oil cooler?

If it's on the passenger side it's the engine oil cooler.

Yep. Oil cooler. You should probably keep that.
