Hi Eggsy - yeh they just don't pull out as the
valve gets carbonned up inside. You need to remove the stop valve housing above it first and spray plenty of carburettor cleaner around and down through the port inside the inlet manifold. Then using a small punch about 8m in diameter start to tap of the inner edges of the valve in order to get it to rotate in its housing - it will normally take many attempts spraying cleaner in and tapping it back and forth until it will even attempt to come out - once it starts to move outwards spray even more cleaner around it and very gently tap it back home so that some of the cleaner is taken back into the housing - in all honesty I spent about 3 hours working at mine.
Have a look through the link below.
Today I cleaned my EGR valve, want to see how it looks ?
