  1. emlynt - did you ever resolve this issue? I have the exact same problem. At rest and driving around town my light pods are fine. Above 40MPH and the passenger pod starts winking up and down. I see Atwell's answer above - I have the older style motors which don't have the pucks so that can't be my issue (I have an 86).
  2. I was just at the Academy in August, doing the Licence Level 1. It was one of the most amazing days I have had since becoming a Lotus owner 17 years ago. I met some great people, learned a ton during my short runs in the 220 Cup, loved the factory tour seeing the same facility where my 86 Esprit was built... What can I say? As an American fortunate enough to have had the opportunity to go right before it closed, I will say it was a fantastic experience. I am sorry to see it go.
  3. Hello there! Where have you been? Hope you still have your car and doing well. Please send me an email, I am still hanging onto my '87 so far. Cheers,

  4. MAJOR UPDATE The mechanic has done a lot of troubleshooting. The results so far: * Items Checked* loose header flange valves need adjusting is the 60ft-lb. nut on the crankshaft (holding the pulleys on) tight exhaust manifold gasket exhaust related issue, usually the fasteners are the source of the problem lift the cam covers and just check the cam profiles valve lash check timing spark plugs start the engine, then pull the spark plug wires off one at a time
  5. Update: The wastegate was removed and reinstalled, removing a small gap that was down there. No change in the sound. (But the turbo lag is gone.) Valve lash was checked yesterday and everything looked ok. Still working through some of the other suggestions. Thanks again!
  6. Craig - Thank you. I will try to post a new video/sound clip with the engine revving (except I don't have the car anymore - it is in the mechanic's hands). But I passed along your suggestion.
  7. Thanks everyone for the replies. I also posted on the Turboesprit Listserv and some good ideas are coming back there. I will be sure to update this thread with the resolution if/when it happens.
  8. The latest in troubleshooting: The sound seems to be influenced more by the accel/decel mode of the engine than anything else. The sound seems mechanical and in sync with the engine speed, whether it's half/same/double speed I'm not sure. Next step: change the oil filter and add the new oil then run the engine again. An old timer at the NAPA store has heard a lot of engine noises over the years, but the fact that the noise is louder when accelerating and quiet when decelerating left him scratching his chin. As for a broken Piston, another fellow had three broken pistons in his V8 and they didn't make any noise. From what I could see of your Pistons and Rods, they seem OK. The next test I'll try is to check the valve lash, The noise doesn't seem to come from there, but... Depending on the result I'll remove the three V-belts and run the engine for a half a minute. That should eliminate the Vacuum Pump, etc. The engine has never had a full rebuild; it has 66k miles on it. It was out a few years back and the valves were reseeded, new piston rings, new timing belt (and a couple since then), probaly some other items I am forgetting. Last year the engine was out for a new exhaust manifold. I replaced some of the AC pieces last year and have not noticed anything out of the ordinary regarding heating and cooling.
  9. Interesting. I just had the exhaust manifold replaced last May, although I don't remember this sound last year. How bad a job is it to replace the gasket?
  10. Thank you for the input. These are all deeper suggestions than have initially been thought of (i.e. vacuum leak, vac pump, bolts attaching exhaust manifold to engine, etc.)
  11. I have a loud knocking sound coming from the engine compartment (video clip with audio here). This is what the mechanic has diagnosed so far; I am looking for additional insight:

  13. Anyone have an alternate part number for the steering rack gaiters? They aren't hugely expensive but I always like to check around to see if the part was sourced from another vehicle. Jeffrey Hammer 86 Esprit
  14. Mark, This is a very timely post. I am just about to remove my steering rack to replace the two gaiters at either end. Any advice, pitfalls, etc. you can pass along? Jeffrey Hammer 86 Esprit
  15. Chandra, Since posting my message, someone pointed me to a Four Seasons unit. I don't know what I need. I attached an image of the specs - does this look like it might work? dryerSpecs.doc
