I took off my EGR valve and intake manifold and cleaned all of the gunk out (it was bad in the EGR) after my turbo started to cut out if I put the engine under load (up a hill for example) and went past 3000 RPM.
I put it all back together and just wondered if I've got the manifold gasket back on correctly? If I haven't what would I notice when driving?

Also I read that you should put a screw in the pipe coming off the top of the EGR which I have (see photo) have I got this right?

Many thanks,
