I'm pleased to report success on the bypass of my EGR today. I bought a new EGR tube from MB. I then cut off the lower 1.5 inches of it. I turned a stainless steel plug exactly the Internal diameter of the tube and pressed it in. I then made multiple little cuts in the tube's end and bent them over and sealed the exhaust side with High temp silicone sealant.
For the EGR valve side. I made a plug on the lathe and bored it 3/4 part way and 7/8" on the other side. It too was pressed into the tube and the little air filter was pushed into the stainless adapter.
I retained the old tube for inspection purposes.
It drives much better and NO CODES are generated!
I've attached photos of the plugged exhaust manifold, Filter and filter stainless adapter. All turned on my Monarch lathe!
