Td4 wasp nest

If like me you shrug the comfort of 4 wheels for a 2 wheeled grin giver then you also know that wasps only purpose in life is to fly in your visor or unsecured zips and buzz around you when stopping for a brew. So it has become apparent that some species are prone to building nest in Freelander exhaust and these are particularly difficult to remove on TD4's. So time to take a look and first thing to remember is if it's original back box the clamp is spot welded on too the inlet pipe so be careful how you treat it, jack up the car as you can't get the centre section clear and it must be removed fully for inspection. Now I took a look inside and sure enough a honeycomb was present so armed with a 18" masonry drill piloted a few holes

Then with an old shower pole and a hammer set about cutting sections out and dragging larger pieces out with a wire hook.
Surprisingly I didn't find any dead wasps but felt the need to completely remove the nest in case they returned, watch out as the tricky buggers build it right into the edges and we wouldn't want any breaking loose and causing a blockage. The finished result after several shakes should be fairly clear and any remaining cotton wool or dust will pass through after a couple of full throttle moments.

So end result is 3hr start to finish and no fear of wasps for summer, and maybe a slight increase in torque as the turbo appears to spool up a bit faster

Would it clear if you started the engine? Just wondered.

Well all I can say is after a few days normal driving it certainly pulls more and gives better breathing at high revs. So far it is worth the effort and with an mot at the end of May I will put that "visual test only" to the test.
