Thanks, Terry.

I just got back from working on my truck and did this:

Removed the pipe from the egr valve to the intake mainifold, pulled vacuum on the egr and exhaust gas is popping out!

So, it looks like my problem is in the intake manifold. Again, the engine does not stall when pulling vacuum on the egr valve and now we know that gas is getting to the intake manifold. Also, the engine does not die with the egr valve disconnected from the intake manifold. me thinks that should be huge air leak??

Can you tell me which hose are the plenum ones and how to clean/clear?

thx

I cleaned mine from the exhaust side, using a gun cleaning solvent sprayed into each port then after soaking for a while, used compressed air to blow the passages out (lots of black sooty solvent comes out the EGR valve port.

Actually the EGR ports are below ports 2 and 3. They look like they'd be bolt holes but they're not and you'll see on a stock manifold they pipe straight inside. A header blocks the EGR ports.

Bolt size for the passage plate?

I've been trying to get the last two bolts in (motor is in vehicle) for the EGR/ coolant passage on the back of the head, but they slide right past the thread. They are the right bolts, I marked them when I pulled them, but it's just not working. What size are the bolts? How necessary are the bottom two bolts? Any help appreciated
