EGR delete leaking coolant

Hi guys. I found that I have a leak where the metal tube from the EGR delete goes to the underside of the intake manifold (the teardrop shaped plate). It feels like one of the two screws holding that plate came out (or maybe broke off). Is there any way to get a new screw into that without tearing everything apart?

Also, does anyone have any clue what size that screw is? I don't see it at the moment, but I suppose that if I have to tear it all apart I might find the screw in the engine valley.

Thanks!!!

The 2 bolts holding on the plate come in from the top behind the area of the alternator. They wouldn't fall out but they could loosen up. You'd end up with a boost leak though as the plate is used to seal up the EGR inlet part of the intake manifold

I don't like the 2 piece designs and I always tell people when I see them that they are not reliable. The coolant leak is likely from poor tolerances in the design.

Not the 2 bolts on the top. The two underneath where the metal tube from the EGR delete (or EGR cooler) mounts up to the intake.

From what I know about EGR deletes they should bolt up from the top in the same manner the EGR cooler does. The plate that holes the tube in place should be threaded so it accepts the factory EGR cooler mounting bolts....

Now I haven't seen every delete out there but either way you may want to look into getting a more reliable one

Corrosion builds up on the intake manifold sealing surface too. That never helps either, a lot of times I will take some green scotch brite and clean up the area. Same principle applies to the oil cooler cover. Both aluminum surfaces are subject to cooling system corrosion and the scale that builds up can be the cause of the leak
