I'm in the middle of removing my plenum. My car has had the solenoid disconnected from the EGR valve as it was faulty and causing poor running. Can I blank off the two holes in the underside of the plenum where the EGR pipes join it and leave everything else as it is? Any help appreciated

i dont believe so mate. if you leave them off you will the need to blank the pipe from the exhaust also

 

And that's the hard bit, couldn't shift the bolt in my manifold so left it on for now until the engine comes out next wnter.

i also couldent shift the bolt so i cut the pipe and welded it up. worked perfect for me:)

 

Thought about it my welding isn't great!!

Because the solenoid is disconnected, isn't the valve shut and therefore effectively blanking the exhaust off?

technically yes, unless the valve/diaphram is faulty...

Cheers for the replies, I think I'll end up blanking the pipes and the plenum to ensure no leaks.

mine seemed fine doing just that mate, didn't drive it much tho, I had the plenum off, so I cut off the EGR plenum pipes as far back as I could, made some blanks for the plenum, then whilst I had the gear box off, removed the EGR jobby, but the pipe going to the manifold is a travesty to get off mate! I managed it tho, but I did have the car on a lifter with no gearbox on, then I got a bung and bunged it up...
