VW T5 2.5 TDI AXD engine Valve cover removal 10 min whithout removing front and Intake Manufold

The Hardest part is to remove de M6 Bold In The Middle that is located Right under the intake manifold. I removed this Bold permanently I cleaned The service of the bold hole very good with Brake Cleaner, and fild it up whith Silicone easy gasked Then i filled up The valve cover gasket also with Silicone gasket and it does not leak so next time you can remove the silly designd cover in 10 minutes ;-) And I&recycled The Bold that i left permanently out? Its now sticking It in the engine gas recycling Hose ?
