I been trying to unscrew this and is snapped . What is the best thing to do, I heard that is not really necessaries, should I just block the holes?

If you are deleting the EGR and cats, then it can be capped/welded/blocked up

Yeah mate, that's you EGR, unscrew whats left from the manifold (will be very tight), find a suitable bung for it (I found an iron one from a plumbers that fitted perfectly) and remove the two metal pipes that go to the underneath of the plenum, make some plates to block the holes under the plenum, or use the ends of the pipes filled with weld, and remove the actual EGR unit in the centre at the back of the engine, 2 bolts hold it on, have a search for 'EGR delete' or 'EGR removal', should find a guide....

Get the grinder out and cut that crap off

A 5p fits in the hole perfectly. Although mine did start to look a bit strained after testing it so I used 2 5p's and welded it over for good measure.

I used a 1 pence piece lol
