Here is the end of the story. I traced the lines back to the connector for the programmer. When I too the connector out, the nipples were not cracked, etc. However, when I plugged it back in, the air conditioner started to function properly. Go figure. So, I took it out again and looked more closely. The nipples were soft, and I have come to the conclusion that one or more of them were collapsing. So, I cut all of the lines, spliced them, and bypassed the connector altogether. The a/c vents work beautifully now...no problems.
Thanks again for your help. The photo was very helpful as well.

i have a 93 lesabre 3.8 with very low miles that i got on the cheap about a year ago so i really do love her but now i've got a problem. what could cause it to die completely with no warning while driving . it won't jump and doesn't seem to take any electrical at all as in when i hook it up to jump lights/radio/windows still won't work and there is still no clicking sound when the key is turned, just nothing . i'm thinking possible a bad alt or a short in the wiring somewhere but how do i test these ? fyi the battery is only a year old so that should be fine . this is getting so hard to pin point that i may have to take it in for this one ( i hope not!)someone is stopping by soon to give me a hand and bringing his voltmeter so we can test some things but any advice from the forum is still more than welcome !!!!!!!!(also fyi it had been sitting outside in the rain for a while before the last time i drove it, then i got in it to go to the store and then about 2 blocks from my house it went completely dead and has been since )

so the battery tested fine(12.3) . the fuses are fine . just no electrical power as in no horn no lights and when the key is turned no clicking sound . does this mean the ignition switch ?

oh hey never mind . got it working by simply wiggling the positive cable to the battery . i read in another forum that side post batteries are the biggest flaws in gm cars and that 99% the time are the cause of electrical problems . So if you have one always try this first and once you get it started and around some tools tighten and clean her up .

i ended up changing the front oil seal, oil filter adapter and timimg chain cover, and the timing chain cover ended up being the problem, it dont leak no, still doesnt get good gas milelage and iv changed the wires, sparkplugs, and ignition coils,
#174 of 188 1997 buick 3.8 LeSabre EGR tube, Intake or heads
Sep 15, 2011 (7:10 am)
I have been reading on this board trying to track down a problem. I have water in the oil of a 97 buick LeSabre.
In this post
imidazol97 says that it is most likely the EGR tube inside the upper intake leaking. Can anyone point me to a thread on repairing or replacing the EGR tube or does the whole upper have to be replaced?
Getting parts down here is a PIA so I need any info you can give me as each time I guess it costs me 2 weeks waiting.
Also is there anyway to bypass this as it is never under 80 deg F down here!
Thanks for the help.

Head gaskets very rarely fail unless the car has been overheated.
The upper intake does fail with leaks where the EGR gas goes through the plastic upper to be mixed with the incoming air. The plastic deteriorates into granules and seeping begins losing coolant from the passages that go through the upper intake manifold (UIM) to the throttle body.
The lower gaskets between the metal lower and the cylinder heads also need to be replaced to be sure they don't start leaking directly into the cylinders while coolant is under pressure. Sometimes this fills a cylinder and hydrolock occurs.

Is a source for the GM metal framed lower intake gaskets.
Here is APN's version of the upper fixed to prevent a repeat failure in the EGR area. Notice they use a metal sleeve to help spread the heat from the gases.
http://www.ineedparts.com/auto-parts/intake-manifolds/gm-intake-manifold-kit-178- - - - 06.html
All versions of the upper from Dorman and APN have a reduced size stovepipe on the metal lower that carries the EGR gases through the upper. That's even if the part does NOT have a metal sleeve.
Note at the bottom of that page they offer a combined price for the metal framed lower and the upper.
I don't know how shipping is handled outside US. They give a price for US 48 states shipping. That implies they do ship outside the 48.
Is the oil a milky color instead of a clear oil. If so, that oil needs to be drained and replaced, even using cheap oil until the source of coolant can be fixed. The coolant turns acidic and affects the bearings and surfaces.
I think I can link you to some how-to-do-it repair sites about repairiing the upper and lowers. Send email to address that shows when you double click on my name at top of this post.

I'm rallyvee, but I seem to have forgotten my password, so I'm using another family member's account to make this post.
To follow up on this for anyone else who might be having this problem, the starter needed to be replaced. I was lucky to get stranded in my own garage, but that was sheer luck...I drive to other towns a lot, and I could have been stranded far from home.
So if your car has these problems, look into replacing the starter, even if it seems to be working.
Thanks to everyone who offered advice.
