  1. Thank you so much for your help and advice. This is how my weekend panned out... I eventually managed to remove the air intake box by disconnecting the main air inlet hose that attaches to the lefthand side of the intake box and sliding the box backwards so i could remove the restrictor trumpets. Once the restrictors were out, i could lift the box off the manifold. The restrictors and the box were all covered in thick black tar. I was able to clear most of the mess out of the box and pipes using some heavy-duty paper towels. There is still a thin layer of the tar all over the inside of the box and some in the pipes which i couldn't quite clear out. I intend to get all of this cleaned when I get a nice weekend. So that was my first job (half) done. With everything back in place, I started the engine. It ran for 2-3 seconds and died! Next, I decided to blank the EGR and its vacuum hoses. (at this point I assumed I had nothing to lose). I eventually removed the lower bolt that holds the EGR and also the dipstick with some penetrating oil and a pair of heavy mole grips (and some offensive language). The EGR was so caked in exhaust crud that i was unable to move the valve with my thumbs. I decided to just blank it off rather than clean it and have it poison my intake for a second time. I made a crude blanking panel by taking the EGR gasket into the kitchen and used it as a stencil to draw round on the bottom of a cake tin. Then snipped a new gasket (minus the hole) out of the cake tin and reinstalled the original gasket together with the new blanking gasket between the EGR and the manifold. I also blanked the exhaust inlet with a 2 pence piece and tightened it all back together. (after all this, I also elephant-modded the CCV with a dishwasher waste hose). So, expecting nothing good to happen, I sat in the driver's seat and turned the key. It started running roughly and, after a minute, calmed down and started ticking over normally. After 2-3 minutes, most of the smoke had died away and I decided to see if it wanted to actually move. It pulled away very reluctantly, stalling a couple of times but kept re-starting and getting more and more revs and distance after each start up. Then it just carried on going and the smoke gradually disappeared completely after about a mile. I drove back home to check my work. Both the front-end and back blanks on the EGR we holding firm and airtight, with no leaking gasses and the elephant was still in position. Since Sunday afternoon i have driven about 90 miles and the Lupo drives like a new car! Much more pull than before and what looks like better MPG. I really need to remove the inlet manifold completely and give it a damn good clean because there's still some of the EGR/CCV crap in the holes which i didn't want to try and clean while the manifold is in position incase I drop any of it into the valves. And also because the lack of CCV vapour might cause the sludge to dry out and pieces of it to break off and get sucked into the engine. I don't actually know if that's possible??????? To conclude... I wouldn't have had the knowledge or confidence to do what I did if it wasn't for ClubLupo, so thanks for creating this brilliant website!!!!! BTW - does anyone have a step-by-step walk-through guide on an SDI cam belt change??? Peace!
