  1. Hi Guys, I am thinking about doing the above and was doing a little research and found this thread. I actually have a hybrid and I am not 100% sure which series/90/defender body has been put on. From above it appears to make a difference if I want to remove the bulkhead. So, I was wondering if anyone could help me identify which one I have. Could someone advise what are the different widths for the different variations? I suppose it is dependent on your replies but which version is the best, the muduk or the tubular version? Thanks in advance. D
  2. I'll investigate and post if I figure it out. Tks.
  3. Just to confirm it worked. Thank you guys sooooo much. I can now enjoy the fun bit of tuning and getting back on and off the road. A possible side effect may be that the idle screw may have been blocked at the same time. It is now making no change even when screwed fully shut or removed altogether. Don't know if anyone else has had this issue. I need to investigate it's air path and figure out if I have sealed it aswell! Anyway, that is a problem for another day. Thanks again. 🖒
  4. I attempted to undertake this today and thought I would put up some info for any others who might come across this problem. I did not have a tap large enough so I got a bolt which fit snugly in through the first hole and slid into problem hole. This took a bit more drilling out to get the same size drilled hole as the inside one. I slid bolt in through new drilled hole and then put sealant on it and slid it in on into the corresponding air hole opposit it inside, which is where the air was leaking. Hopefully this will give as close to air tight as I could. I cut the mechanism off the end of the stepper motor, then attached a metal plate with sealant where old stepper hole was and then used old stepper (now with flat bottom) to fix in place. I forgot about taking photos of each specific stage but the following will show the bolt in situ (with probably too much sealant making it look very messy) and then the finished photo showing the old stepper holding a metal plate, which you can just see the corner sticking out. So hopefully all sealed up now. I couldn't check as I have no oil or water in the engine as I am also working on oil pump plate. Anyway, I will follow up with results when it is up and running to close off but obviously this or something like it needs to be completed by anyone switching to PWM from plenum stepper configuration. Fingers crossed.
  5. The hole is blocked off on mine, so I drilled it out. Your photo gave me the confidence! I shoved a rubber pipe in to see if it has sorted the problem and I think it might. So, I thought I would put some photos up to help someone else in the same situation. I now have to try and tap it, not sure if I have a big enough tap, or find some other solution. I will post again when successfully completed. Again, thank you for help.
  6. I will get a chance to check later today.
  7. It was a flapper originaly but now PWM. But actually I just realised that I got another plenum/manifold from Nigle when I bought it so it is actually a 3.9 plenum. Either way I didn't notice hole there.
  8. Mine is 3.5 but will have a look and see tomorrow what I can come up with. Tks again.
  9. Tks FF. I think I found the solution 😀
  10. Tks for the info. It is good to know what I have to do even if I don't know how to do it. FF, I will have to make sense of your photo and have a look at mine as I don't think that I have a hole where you appear to have slid in the cylinder in. But maybe it is there and I just have to drill it out. Cheers guys
  11. Tks hi lo, but I am not trying to get the stepper working as I have a PWM, I think I simply need to close off the old stepper to stop air leaking in to plenum causing high idle. However, you might confirm, as the stepper is no longer wired up, I presume it is not as simple as sticking 12 volts across the terminals to put it in the fully closed position. Tks
  12. Good morning PeteMck, I think I am having the same problem and need to seal my defunct stepper. Did you machine a piece with a conical end to match the stepper or was it just a cylinder shape in as far as possible. This may save me pulling the last few hairs out of my head in frustration if it solves it. Tks in advance for any advice.
  13. Hi again, I found a post that I thought I had read before but couldn't find where you answer the problem. I guess I have to figure out how to block off internally..... don't suppose you ever came across how to do it? I will have to find an internal diagram or something to see where air flow goes so that I block it correctly.
  14. Ah OK. Bowie, I have read a lot of your posts and you seem to have a good handle on things, can I ask a question relating to the above high idle. I have MS1/EDIS/PMW so do not use standard stepper. I read that this redundant part may not be sealed leading to an air leak. I took mine off and put a sealant on and reattached. It didn't make a difference. On further reading I now wonder if the old stepper rests in an 'open' position thus actually requiring me to seal it internally and not just around the connection? Have you any idea? tks
  15. Just wondering if you ever solved your problem of high idle? I'm having similar problem.
