  1. My exact thoughts only mine is a 98 Deville...$.6000,00 and counting, repairs are never ending. 174,000 miles...Never again for any high mileage old car. They are nothing but money pits.. Buyers remorse ?. Oh hell yes
  2. Please excuse my ignorance on this subject my statement was all wrong. Overfilling does cause leaks and excessive oil burning due to it being picked up by the PVC system. I apololgize for making such a statement.. DONT OVERFILL.. By the way on NS engines only go 2 marks above the ADD line. If you take it all the way to the top mark You've overfilled by at least a half (or more) a quart. Blame the engineers for this screw up. Apparently I've been overfilling mine for a couple of years. But yesterday I changed my own oil put 7 1/2 qts back in and it registered 2 marks above the Add line. When your level shows right at the A your one qt low When it shows clear at the end of the dip stick your 2 qts low. Your still ok if the low oil light comes on because you still have 5 quarts in the system but should add oil asap. The engineers didn't "screw up" anything. The dipstick is calibrated for checking the oil when hot, not cold. Then I stand corrected again my apology..

  4. Yes as the title states this is a myth if by overfilling the oil sump on a NS engine you will cause it to leak or burn excessive oil. Nonsence ! By overfilling the sump by lets say 1/2 quart you raise the amount in the oil pan about 1/2 inch.. Look at a picture of the inside of the NS oil pan and tell me how it could cause those two conditions..This is a myth started on the internet. And almost every NS owner believes. it..How overfilling can cause more oil consumption or to burn more oil is just folly..If you think not prove it...
  5. A woman on another Cadillac site had a 98 Deville.. She loves the car although she has of this date put $8,000 in repairs in it. I'm not quite that far yet but Ive got a half a dozen codes showing plus the tranny is slipping at take off. Welcome to the club. Just remember old caddies are not for old men as I have found out its not your daddies Deville. The NS engine is very complicated and foreign to me. A friend of mine took 4 hours to replace the pos battery cable. Why ? Because the starter is under the intake manifiold cover. I just pd. $270.00 in labor only to have my alternator replaced. A job I used to be able to do myself in 30 minutes. Why ? Check out where its at !! Good luck with your Cadillac my friend..
  6. This battery was 100% dead before I bought the car. On your advise Iam going to replace it along with the new alternator. Im keeping my "old" alternator and going to have it rebuilt with American parts then I'll use it if this new one blows..Thanks for this idea I think your right..
  7. I got the new alternator from NAPA I dont think its made in the U.S. I will have it installed but if it goes again I will find a repair shop and have the parts replaced with parts made in the U.S. Got the message guys and thanks for the info. Now Im a little worried about taking it on a 2000 mi trip to Ca. and back. Hope it holds. Also I understand its common for alternators to go out in these NS engines because of excessive heat down there especially while waiting at red lights. Heard you could fry an egg on the alternator. Thats why cheap chinese bearings and electronics dont work too well. And yes it has a lifetime warranty. But there still is the fact that labor has to be paid all over again Don
  8. Ok I ordered a new alternator from NAPA. I would assume Delco. I hope thats built with quality parts..Its not a rebuilt.. Oh I had a hunch I would get answers like these. I agree with both of you..This is the first car I ever owned that I couldnt put an alternator on without going through a lot of b.s. to get it off.. I wouldnt even attempt to do this myself. so will have to pay the local repair shop to do it for me. Its a mystery to me how they even get it out of that enclosed space. Thanks Don
  9. This is my second rebuilt alternator to go bad. Could something else cause these to go bad or were they going bad from the start ? In other words just bad rebuilds ?
  10. Run dont walk, away from this "Deal" You'll be sorry later as it sounds like a huge money pit Keep looking. I personally wouldnt touch this car if it were free...
  11. Oh WOW Jim,sounds like this will be a real booger to find.why oh why did they make these cars so darn complicated ?? I would have preferred just the minimum (engine, four wheels, brakes etc.) I dont know if I can even find this stuff. But thanks for the info anyhow..Regards Don
  12. Code tcs pwn link..(PO) Whats this ? Anybody know ?? And how serious is this code....
  13. "Critical to use the sealer in the 4.x engines" The Northstar is a 4.6 engine. Therefore I should use it ?? I "THINK" he meant the 4.x engines "BEFORE" the Northstar... Meaning the 4.1...4.5 and 4.9 engines Ok Jim think I'll just pass on the sealer...ThanksDon
