#15460 of 15500 humming sound
Jun 10, 2011 (1:43 pm)
i have a 2000 lincoln ls with 86,000 mi. when i'm driving the car makes a humming sound, the higher i accelerate the louder the sound. i thought there maybe a leak in my exhaust somewhere, but that's not the case. does this sound like a transmission problem?

If your heart is set on it than get it. Just make sure your mechanic is familiar with that vehicle so he can perform an educated inspection of it. Now with that said as the owner of a 2000 Lincoln Ls myself, I would advise you NOT to get it.

So I finally got a chance today to start my big 135,000 miles LS V6 tuneup project. Pulled 2 plugs on the driver's (easy to get to) side and both plugs and their coil boots were nice and dry! Excellent.
Then I pulld the third one. Oh well, 2 out of 3 aint bad. THe coil boot was covered with oil and the plug recess is full of it. I thought for a few minutes I was one of the lucky ones who would not have to replace valve cover gaskets. Fat chance, huh? SO I'm off to the parts store. Hope I can finish this today, else the wife has to take my Navigator tomorrow.

The valve cover gaskets will wear out on ANY car with over 100K on the clock. I had mine done at about 140K.

Hey Mike ... good to talk. Do u have 0, 1 or 2 LSes curently? Do u know if the 'other' site is defunct?
And to all and Mike -
brief report on my 'tuneup' exploits.
I got er done, though it took a week. Glad we have 2 vehicles. It took so long because: 1)I'm not the world's best mechanic; 2)I didn't have a shop manual when I started and consequently broke something I may not have broken had I the manual. I did purchase a 30 day access to a shop manual at helminc for $20 after that. Glad I did. 3) The thing I broke took a while to come in at local Ford dealer (no local Lincoln dealer anymore.) 4) Job was a bit harder than I anticipated. 5) Had to buy or borrow a couple of tools. Deep sockets mainly.
So what I broke was a little bitty hose nipple which comes out of the upper radiator hose and goes to the throttle body. Course there's no way to fix a broken nipple so I had to buy - the whole GD upper radiator hose assembly!!! It included no fewer than 5 hoses and connections as well as a new thermostat. $301.00 plus tax. Ugh. I also had to buy a new PCV valve hose assembly as the little plastic feet broke off when removing from the valve covers. $25.00
Anyway, I replaced the plugs. The two rear wells had oil in em. I did not replace any coils, but I did replace all the coil boots. I replaced the valve cover gaskets and I replaced the PCV valve. Which caused me some more headaches cause I had to remove the lower manifold to get to it. Arghh. So then I replaced the lower and upper manifold gaskets. I would have been done then were it not for the broken nipple. So then I set about replacing the upper radiator hose assembly. And I figured since I had real easy access at this point, I also replaced the serpentine belt. That was far easier than expected. I thought about replacing the lower radiator hose as well for preventive maintenance but that's as far as I got with that.
So I got her all back together and fired it up. Took 3 tries before it caught and she ran smooth as a top. Really running great. But I did and maybe still do have a slight issue - it overheated first time I took it out on a hot day. Interestingly it overheated right in the driveway of speedie oil change. (I was too all-in to jack it up and change the oil So while they were changing the oil, their mechanic came over cause he liked the car-especially the manual tranny And he had seen the coolant overflow and asked if I had burped the system after replacing the hose. Of course I had and had followed the shop manual directions. He opined that I must've left air somewhere in there and said what the heck, he'll bleed it right now after new oil in. So he tried to do just that but found that there was no water in the hose on the radiator side of the thermostat! I nursed it home with the heater running on 98 degree day. Next morning I put the old thermostat in the car, bled the system again and it hasn't overheated since and I can feel water in the radiator hose 'above' the t'stat. I'm not 100% sure I've solved the problem though since had a little puddle last night after returning from 30 mile trip. I *think* it was coming out of the heater bleed hose though cause I had only finger tightened it and now took a screwdriver to it. I'll know more soon. If not that then mabye a hairline crack in the degas from it getting hot? - this was the first time the temp guage needle went above the 9 oclock position. It went to about 11 o'clock when it overflowed.
OK, TMI perhaps but there it is. I still need to take the 'new' t'stat to Ford and see what they'll do for me if anything.
Summary - was worth it cause car runs like new again. Was not fun though and cost about $600 with half of that being the darn hose.
Wish me luck on the overheating issue and talk soon all.

Thanks for the info, I'm not brave enough to work on mine except oil changes and I did change three coils and plugs. Got an '05 V6

Just another brief (ha) message re working on my LS.
First, I just advise anyone except really experienced mechanics to get the shop manual or something equiv. I only got a 30 day subscription at Helm. I need to buy the real thng next time.
Anyway, I finally solved the little issue that came up after I did the tune up and replaced the upper radiator hose assembly and more. As I mentioned, it overheated on me first time I drove it hard afterward. This was first ever overheat. I dont know the cause for sure, but I put the old thermostat back in and re-bled the system and it hasn't overheated since. I sort-of bench tested the new thermostat which came with the hose assembly and it seems OK to me. So I must assume that I did not bleed it correctly the first time. At least I now have a spare T-stat!
In any case, after all this, the car would lose some coolant from the degas bottle area after a hard drive and shutdown. Not much, but had to be solved. The heat and pressure from the overheat must have opened something up. I could not see the cause until I finally tore into the thing to get the degas bottle out which required removal of wipers and cowl and cross-member and finally the engine end of the degas bottom hose. The leak was around that bottom hose at the bottle. I suspect that replacing the factory spring-type hose clamp with a screw-tight type clamp would have solved the problem. However I could see that some corrosion inside the bottle had eaten away at the interior hose and metal stuff - there were actually bits of metal stuck in the small overflow pipe at the top - plus it looked like a crack might be forming - anyway, I replaced the bottle ($100 !!!) and the hose and she's tight as a drum now. Bottle came with a new cap which seems a lot surer than the old one. WTH, it was 10 years old after all. We plan to keep this car another 10 years, knock wood, my wife and I love it.
So yesterday I measured mpg on a 300 mile trip at 75-80 mph on the highway, and it was 85% highway and the number is just shy of 25mpg, which I feel is pretty darn good. And the thing really kicks it too. Winding it up over 5 grand in first and second is great fun in this manual tranny relic of a Lincoln.
