I had the same problem with my '87 Buick LeSabre 2 years ago. But it didn't seem to fit right, the car was running fine up until it just didn't. I had 3 professional mechanics swear it was a blown head gasket. I researched thoroughly and found out this particular engine make has a DEFECTIVE upper intake manifold which can break down and cause coolant to leak into oil, simulating a blown head gasket. The NHTSA had issued a recal on SEVERAL GM cars with this engine, EXCEPT for the '97. I filed a complaint with the ODI and as of today it is now COVERED as a "Defect & Recall". NHTSA ID number 96V116000. This MAY be your problem if it is NOT the "usual" blown head gasket. Hope this helps.

I know this is an older problem, but this just might help someone out there. Just because your car is smoking white and then will not turn over does not necessarily mean that the engine is in need of replacing. The intake is prone to cracking around the water passages around the EGR ports in the intake. When this happens the intake sucks water into the cylinders and smokes/ or steams like a leaky head gasket. when you turn the car off, if the cam ends up in the right position and the intake valve on the cylinder close to the leak stop in the open position that cylinder will fill with coolant and hydro-lock when you try to turn the car over. pull all of your plugs and see if the engine will turn over before calling it done.

White smoke is an indication of a head gasket problem which caused antifreeze into the engine....the fact that your motor will now not turn over now means a seized motor.....the only help I can give you with this one is to replace the motor.

White smoke blowing out the exhaust pipe


Sounds like a head gasket leak. Have a cooling system pressure test and cylinder leakdown test performed. In the meantime, you should NOT drive this vehicle or you'll cause more damage.

97 BUICK LESABRE WILL NOT START CHECK ENGINE LIGHT FLASHES AND WHITE SMOKE COMING OUT FROM TAILPIPE


Check to see if the coolant is low in the radiator. If it is than you probably had a rupture in the plastic intake plenum. Really common. If you pull the plenum and there is a bunch of coolant underneath than you will need to replace it. There is a coolant passage around the egr tube. After years of high temps from the egr tube the plastic weekens and finally ruptures. The aftermarket (dorman) plenums are reinforced in this area along with an updated egr tube. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Antifreeze in the motor wut do i do?


It's normal for the check engine light to be on when the car's engine is not running. If the car is turning over but won't start under its own power, then there maybe another problem unrelated to antifreeze being low in level. Did you ever notice white smoke coming from the tailpipe indicating a head gasket leak? If so, then the antifreeze is likely coming out of the tailpipe when running, or there is a slow leak in something say like the water pump gasket or shaft. It's a good idea to check what codes are tripped using an obd-II scanner to point you in the right direction. Good luck on this repair.

Changed spark plugs in 97 buick lasabre and now it cranks and runs, but white smoke coming out. Is that blown head gaskets? Does it have anything to do with the fuel pump my mechanic put on 3 weeks ago???


You need to check the oil with the dipstick (wipe in down a few times) to see if it looks like a chockalate milk shake. If coolent has made its way into the oil you have blown head gasket. The fuel pump which is usually in the gas tank in most gm vehicles would not cause white smoke, if it failed you car would not start because your engine would not get any gas to the injectors

Exhaust tailpipe black on the inside is normal, check if you get white smoke from exhaust when engine is hot that means head gasket problem. If car fail going up an hill it is often a compression problem.
If car has automatic transmission, it can be also tranny not shifting down gear, this usually is a module problem, but you told me you checked this already.
Also a faulty throttle position sensor can give transmission problems, but when this is faulty you get troubles with gears on all situations.
