Did a plenum pull on my 300zx na and could not get at the egr right at the back there so rather than disconnect water hoses and piss about for hrs, I found a simple method of disabling the whole thing without removing the valve. note:images taken with shitty 3d camera and are in 3D 1. Get large metal bar 2. unscrew egr tube from exhaust manifold 3 lever egr tube with bar bending it back 4.insert metal bung into manifold hole and screw in 5.use angle grinder to remove egr tubes as far back as you can. 6.remove all tubing and plug up holes in plenum note:your egr pipes welded up will be good for this.
yeah these came out worse than I thought .... I'll take some more pics here's a clearer one showing the power of the metal bar.
