#32 of 62 Re: LeSabre oil leak... [vanderbar] by imidazol97 Mar 11, 2009 (2:36 pm)
Replying to: vanderbar (Mar 11, 2009 10:09 am) If it's under the bottom ends of the lower, metal, intake manifold, I believe those have some seeps around the seals that go across the ends if not installed right or after lots of age. If it's not bad, I'd sure just live with it.   Where are the trans lines leaking? Through the rubber? AT the ends with the metal parts? Where they screw onto the radiator? Is it transmission fluid on them for sure and not oil from the upper part of the motor?

I opened the clamps from the lines, cleaned the hoses, repositioned, clamps and after some days of driving, looks good... Thank you.
#34 of 62 98 Lesabre Misfires by gds52383 Jun 10, 2009 (9:16 pm)
Hi I have a 98 Lesabre with 120k on it. Recently the check engine light came on and started flashing. I took it to advance auto where it was tested and it came back misfire on cylinder 4. I decided to get a new set of spark plugs and change them. I found out it had the original plugs in it. It runs alot better and the check engine light has went off, however, it still hesitates on acceleration and sometimes jerks around 55 mph. I don't think that the problem has been completley solved although it runs alot better. The wires look fine. Could it be the high voltage distributor caps? Any ideas on what I should check? Any info would be greatly appreciated.   ~Greg Replies to this message: imidazol97 (Jun 11, 2009 5:15 am)

#36 of 62 Oil Pan Gasket Replacement by pcjd388 Aug 26, 2009 (8:39 am)
I was wondering how difficult it is to replace the oil pan gasket on a 1997 buick lasabre limited? I have looked at the oil pan and it seems that all I have to do is take off the bolts without having to jack the motor up . Just want to make sure it comes off that easy since nothing on this year is easy to replace...lol Replies to this message: bob252 (Aug 26, 2009 11:55 am)

Replying to: pcjd388 (Aug 26, 2009 8:39 am) OK..This is hopefuly helping you, I have done this and you are correct (simple) #1 remove the plastic shield at the starter (don't remove any more bolts there) (don't forget to drain the oil first HA HA) then remove the bolts on the pan and carefully spin the pan around to #2 remove the bolts from the oil pickup from the oil pump, (2 of them) pull it out and the pan will fall down...I have no idea of why you should have to remove the pan as my 95 had a really thick 1/3 in. plastic gasket on it and I reused it. (225000 mi. preventative maintanance rod bearings) I had an oil leak prior to this but it was from the oil pressure sending unit, another easy job. Sold the car w/ 250000 miles on it with the factory exhaust transmission axles etc. still working fine...How much can they go before something does break? I sold it for $200 to a happy home without any feeling of guilt.
#38 of 62 92 lesabre by donicar Sep 02, 2009 (3:41 pm)
I have a 92 LeSabre 3.8 that has the rear freeze plug missing. I guess someone else replaced it and didn't get it in right. How can I put a new one in without pulling the engine or tranny? If I use a rubber one, how long will it last? donicar
#39 of 62 1995 Buick Le Sabre AC Bypass Serpentine Belts? by polara60 Sep 07, 2009 (1:11 pm)
Over a year ago I was given a 95 Le Sabre for free. Not in bad shape and has a solid repair history and 147,000mi. The AC has never worked. Now it clear the AC compressor is dying...noise and metal shavings below on the frame..clutch issue I am guessing. I really do not want to buy a new compressor and would rather just bypass the AC. In searching the internet there have been several posts saying that its possible with a 70.5" belt v. the standard 102" belt. Another more sensible option is an bypass pulley and remove the AC compressor    I would really value some expert perspective and any experiences other owners might share.   My sincere thanks in advance!   Bob Replies to this message: bob252 (Sep 07, 2009 2:26 pm) polara60 (Sep 08, 2009 11:51 am) imidazol97 (Sep 08, 2009 6:53 pm) cautious_hero (Oct 06, 2009 12:00 pm) cautious_hero (Oct 06, 2009 12:05 pm)

Replying to: polara60 (Sep 07, 2009 1:11 pm) OK These posts are difficult to respond to...due mostly IE 6..(my second attempt).In regard to dismantling the belt forget it...know that the clutch is the problem. There is at the rear part of the belt at the top of the compressor, a plug there, undo it. Then start the engine to see if the clutch is still engaged, if not you are all done. If it still is trying to engage then let it finish tearing itself up untill it cannot engage. I had the same problem with my 95 at 201000, I replaced the complete compressor as it was a lot more cost effective. Do not attempt removing the compressor and attempt a belt resizing it will firstly set a computer code (the light on the dash-"check engine") and try to figure the belt routing???? Really the only real worry you have is the bearing inside of that clutch assembly..if it seizes then you have a problem..Hope this helps.

Replying to: bob252 (Sep 07, 2009 2:26 pm) bob252,   Thanks for your thoughts and IE6 struggles! So got the idea that rerouting the belt makes the engine timing unhappy. So first see if I can unplug the AC Compressor to disengage the clutch with the AC compressor becoming a stand-in pulley. I am concerned about the possibility of seizing. Something in the clutch assembly is creating metal shavings and dropping on the frame below.   Have you ever installed a bypass AC pulley like this as option B?...   AC Bypass Pulley   Thanks so much!
