    98 Deville Concours

Recent Profile Visitors

  1. I had a major miss a while back on my 98 concours, the problem turned out to be worn center electrodes that were much worse on the front bank. The 4 front bank plugs were all around .065 - .070 and the rear bank where all at about .060. I have had some coil problems but that shouldn't effect more then just two plugs I would think, I am also going through about a quart of oil about every 400 miles right now. The plugs only had about 25,000 miles on them and installing new plugs fixed the miss. Anyone know why the electrodes wore so fast (normally they don't wear at all from what I remember). And yes I am pretty particular about checking the gap when I install plugs and we all know the ac delco plugs (which I use the recommended plug from this board) are pre-gapped at .050. Thanks.

    The Rainsense story

    Most of its life it was mix city and highway, lately it has been mostly city driving. I have always driven it fairly hard and certainly did my WOTs when I thought it was necessary (was doing this procedure when the head gaskets let go around 100,000 miles :-). Let me know if you have any luck on finding the windshield info.. Thanks.

    The Rainsense story

    Right now I am running Pennzoil 10w30 but I put the Rotella oil in for one oil change (for extra zdp) and I went from 800 miles per quart down to 400 per quart, I also started getting the dreaded po420 (bad cat). The interesting thing is once I changed back to Pennzoil the cat cleared up and no more po420, and back up to about 500 miles per quart :-). Still a little confused on the windshield, are you saying if I am lucky enough to find an OEM windshield that I don't have to worry about the adhesive as the sensor is already mounted? Can I use any old windshield and mount my sensor on it? And yes I love the Concours :-) Thanks again.

    The Rainsense story

    Thanks rockfangd, just to make sure I am understanding you correctly I will need a windshield specific for rain sense (I see that in your original post now)? Also the part number you gave for the adhesive is aftermarket? I found this on ebay https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=RSK1229&_sacat=0 , do you think these would work? After 16 years with this car (which I have thoroughly enjoyed at 200,000 miles) it might be time to upgrade to Deville DTS (2003-2005 :-). I hate to give it up but it is now burning about 500 miles a quart as well.

    The Rainsense story

    Thanks BBF. Yeah I suppose any of those would work, I just remember all the threads that say to use the special glue and how it has been drilled into our heads on this board over the years to use original parts :-)...

    The Rainsense story

    I need to replace my windshield on my 98 Concours, I am a little afraid they will mess up the Rainsense. Any tips and what glue did you end up using (my understanding is you can no longer get the part number required for our old caddies). Thanks

    Cadillac Radio numbers

    Nice job. So after all your research and hard work am I understanding you correctly that a Bose system will work in place of a Delco system? For example I have a 1998 Concours with the non-bose RDS radio (which I love) can I replace this with any of the Bose or Delco radio from 98-01? Only reason I want to replace it is the tape deck quit working, I have a lot of tapes but that was also used for my AUX out :-).. Also what does the Active Audio do (I am not sure if I have that or not) and can you explain the new AUX adapter you installed from isimple, is it just something that goes on the antenea cable, fm modulator? Thanks in advance.

    Air Ride sagging

    On my 98 Concours the rear suspension would be just fine for short trips but once I got it loaded and out on the road it would slowly leak down until the ignition was recycled. I was stumped because I thought for sure the compressor would pump it back level on the road but that was not the case. Once I turned it off and restarted it would pump up just fine and be good for another couple of hours but eventually it would leak down again (sometimes it was intermittent) and of course no codes (dealer kept saying no codes no problem :-(. Anyway turned out it was the exhaust valve on the compressor intermittently leaking. The point I am trying to make though is at some point the compressor is not allowed to pump the suspension back up when cruising down the road if it has leaked down. good luck.

    Deville Spoiler

    Here you go http://s265.photobucket.com/user/brmurph/library/Deville?sort=3&page=1
  10. I have found the higher performance tire you have the less torque steer you will get. I had Michelin Pilots on my 98 Concours for a while and had no torque steer at all. When I bought the car it had some Goodyear white wall tires and it was a little scary off the line.

    Deville Spoiler

    I have a spoiler on my 1998 Concours, it is very low profile and looks great in my opinion, it has an led light but hasn't worked since I bought the car back in 2002. I don't think I have ever seen another one on the road but they were readily available 10 years ago or so (I would think someone still has some of these but they sure don't advertise them anymore), I have seen used ones on ebay but very rarely anymore. I also have the fender skirts which was pretty rare for 1998. People would give me a hard time about the spoiler on a Deville but I would say it really helps at about 135 miles in hour LOL.. Good luck.

    Struts for my 97 D'elegance

    If your not in a hurry you could try ebay and assuming the part numbers don't come back select "follow this search" and it will send you an email if one gets posted..

    Rotella T interesting results

    Wow so confusing :-), thanks all for the great info. I will change back to regular Pennzoil soon and post my results. I haven't heard anyone say that the Rotella should not be used so hopefully no permanent damage. Certainly not trying to start the typical oil thread as I have seen many of them (which is why I wanted to try the Rotella) going back to the guru. Thanks again.

    Rotella T interesting results

    I wouldn't say no leaks but nothing dripping. I was using regular 10w30 penzoil from Walmart it say Api service sn. The Rotella says api service cj-/sm "meets api service cj-4, ci-4 plus, ci-4,, ch-4, Cg-4, cf-4, cf/sm. .. Did I use the wrong Rotella? no additives.

    Rotella T interesting results

    Interesting. You think the intake might tell me something? It probably has been cleaned in the last 20,000 miles or so but not sure why the intake would have anything to do with crankcase oil? Care to elaborate?? I agree about changing back to penzoil. Will be interesting if I can get back to 800 miles per quart. As far as being a coincidence, I agree burning more oil could be but nothing coming out of the tall pipe seems odd, Seems it must be going somewhere. thanks guys.
