2006 LR3 V8 EGR Valve Vacuum Leak

As stated above, I have a 2006 LR3 V8 HSE with a vacuum leak. After a smoke test, I was able to pinpoint the area of the leak. Smoke comes out of the top of the EGR valve. I removed the valve and ensured it wasn't stuck open or closed.

Question, is the EGR valve supposed to let vacuum through it? I don't think so. Could there be a crack in it? Trying to get some insight before I spend $240 on the fix.

54 views and no thoughts? One of you must have done a smoke test to identify a vacuum leak. Did smoke come out of the erg valve between the electric solenoid on the erg valve and the part where the coolant runs through it?
I'm having the same problem. Did you replace your EGR Valve?
EGR vacuum leak

I just did a smoke test and found 2 leaks I had the code for P0171 bank 1 lean , replaced front O2 sensor then cleaned back sensors , replaced spark plugs and coils , etc all of which it needed anyway it helped ,but I have a intermittent code for bank one and it will miss fire under the right load also . Sometimes runs perfect. anyway did a smoke test . 1 leak was easy around the bottom of the oil filler cap tube. Replaced O rings 2nd leak is around the EGR valve solenoid. I thinking of just doing a block off plate between the EGR and the solenoid . Has anyone been able to link this small vacuum leak to driveability issues ? and I see this post was April 2018 what was your outcome ?
block off

update I just made a EGR block off plate and installed it, vacuum leak fixed !
