  2. Replaced the SU fuel pump with a new one. Got thru the Colorado clean air emissions test without any issues. Now, I have a Collector's Plate and only need emissions test every five years. That is great news.
  3. I just want to let you all know that Caterham Super 7 uses the same S1 mirrors on the side curtains. The same company, same style, but in black color. I have a set on my S1 and they look great.
  4. It worked by cutting off the pipes above the flange, leveled the flange, and bolted back up. Now, my SU AZX 1307 fuel pump is leaking under the front part of the body . I am not sure what is going on. Took it out this afternoon and will take a look tomorrow. Any suggestions are welcom.
  5. The SJ's stainless downpipe does not protrude through the flange. In fact, all the one they sell do not. As far as I know most of cars have flat flanges. My flange is warped due to high temp and will be re-surfaced this week. The only way to do this is to cut off the pipes above the flange. I am going to put it back on without the pipes first. Let's see...
  6. I finally got around doing the downpipe and took it in to the machine shop last week. It looks like I have to cut the pipes that above the flange in order to machine the surface flat. Do I need to weld them back on afterward? I noticed SJ sports cars UK's downpipe for S1 has just a flat flange with out any short pipes. Any suggestions?
  7. Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker did not hold up. It leaks again. I will have to machine top side of the flange to fix it. Tom/Colorado
  8. Greetings from Bishkek, Kyrgyzstan. I installed the down pipe gasket with Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker before I came here. Well, It worked. The trick is to put the sealer on both sides of the gasket and let it dry for 24 hours before installing.
  9. I have about the same reading as you have 8/10 when cold. When the engine is hot on a hot day (over 90 F), it will drop to 1/2 when driving and close to red mark when it is idle. Tom
  10. Yes, I fully agree with you. However, I am going to give a try with the hi-temp Ultra Copper sealer in the morning and see how it work. I will add a short flexible pipe to deal with the movement issues when I take out the down pipe to fix the flange. Tom
  11. Travis,Thank you for sharing your lotus pics. I see my lagoon blue S1 with Victor's S2 and David's black Countach S. Tom/Colorado
  12. The master tech person in my local muffler shop told me this morning to use Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker. Put the silicone on both side of the gasket and let it dry for 24 hours before putting the gasket on the down pipe. He told me the Ultra Copper works for him everytime. Well, I got one from AutoZone will try it after I return from my trip on August 9, if not before. Will update on my results.
  13. John, The down pipe flange is warped as far as I can tell. Tom
  14. I have replaced the gasket but it still leaks at the front (two bolts side) and left side. The flange looks a bit warped. Is there a way to fix this problem without replacing the flange by using a hig-temp sealant? Any recommendation on sealant/paste? By the way, this is a stock fed exhaust system with cat. Tom/Coloado
