#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.

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.

Hey Imidazol97, long time no see.
My mother-in-law's 02 LeSabre has these three lights on. The local shop told her that it's the "Electronic Brake Control Module" and that they can replace it with a used one but she'd have to go to the dealer to have it programmed.
I haven't had a chance to clean the battery terminals.
Looks like you can get these EBCMs repaired and not lose the programming; not sure how easy getting the module off her car would be (remember, we get a lot of rust from the salty roads up here...well, you do too). The screws may be toast. Looks like a pain just to get to it.
Since I'm not paying for it, I'm tempted just to let her go used for $210 installed, and pay the dealer programming fee. One reputable sounding online repair place will fix it for $150 plus shipping, but I'd have to crawl around under the car.
Since it's only (barely) driven in town and not in lousy weather, maybe I should just figure out how to turn the idiot lights off. Especially if the module isn't the real problem.
TIA to you and anyone else for any other suggestions.

If it's definitely the brake module, I would go with the used and switch it myself. The brake connections should clean up with some JB Blaster.
Do the replacement brake modules need to be cycled to bleed them? That requires a Tech II or equivalent tool to make them pulse to clear the air out.
Then there's the dealer programming--can't the local mechanic do that also with the TEch II?
The one thing good about sending off my unit and having it rebuilt is then it's a good unit and doesn't require programming. A used module might, might be a problem.
I've read only a few people who have had problems with these in the H-body cars. But there are a few.

Thanks. Not sure if it's really the module, but not a lot of mechanics around to take it to. Guy has already said he can't do the programming.
#181 of 188 ABS and traction off lights

I recently had the power steering gear replaced on a 2001 Lesabre. Now the ABS and traction off lights are coming on. Is there something that was not connected or calibrated that causes the lights to come on? Could something had been damaged when the power steering gear was replaced?
#182 of 188 Gas tank disassembly
Dec 06, 2012 (9:27 pm)
I have looked, but can someone please send me detailed instructions on the right way to take off a gas tank on a 1997 Buick Lasabre Limited plz. I have to install a fuel sending unit and that costs 128.00 but Im finding out that the fuel pump for it is purchased separate which cost another 75. This will be a first for me on this car but I have done it on a Beretta.
