Hi,

Normally it should be the PCV valve, either stuck or missing but since you replaced......checked/matched the bottom o-ring?

Additionally, have you tried checking the gasket of the lower intake?

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I have a 1996 buick lesabre 3800, just replaced fuel pressure regulator and upper intake plenum and gaskets b/c the EGR valve melted intake and coolant was leaking. I'm getting gas, spark, compression but...


One thing that might cause that is too much back pressure in the exhaust, like a clogged catalytic converter. Try disconnecting the exhaust in front of the converter and see if it starts.

1996 Lesabre Won't Start....


Sounds like the upper intake is leaking coolant into the combustion chamber. Pull out a couple of sparkplugs to see if coolant comes out. Be careful because you may break the starter due to coolant in the cylinder. Replace upper intake plasstic manifold.

Howq do I remove serpentine belt on my 1999 buick La saber


Find the tensioner it will be a pulley that does nothing but put tension on the belt. There should be a square hole in it. that should fit a 3/8 inch drive socket wrench or breaker bar. Use that to remove the tension from the belt and remove - do the same to install new belt

I HAD THE HEAD GASKET SET CHANGED ON MY 2002 BUICK LESABRE. NOW THE CAR STARTS BUT MISSES AND KILLS. WHAT COULD POSSIBLE BE WRONG NOW?


Boy did you waste your money. Head gaskets do not go bad on these engines. You need to replace the upper intake manifold. It is leaking coolant into the combustion chamber. This is a common problem for this motor and some garages will tell you it needs head gaskets. They are wrong! I worked in a buick dealership for 20 years and have only seen one head gasket that was bad on a 3800 engine and it was not a gm original gasket.

Good engine 28 mpg+ hwy. These 3800 engines had upper intake problems and would leak coolant into the combustion chamber. The new ones were re-designed and do not give any trouble. My 90 buick 3800 has 295000 miles on it. If yours is supercharged it does not have that intake problem.

I have a 1996 firebird with a rwd 3800 and i wanted to know if a buick or olds fwd 3800 motor will fit?


The engine will fit but the accessory's. Just make sure you have the same engine which is the L36. if you can get a L26 which would be the years 2005 to 2008 from a Buick LaCrosse, that would be a better investment since it has the aluminum upper intake and stronger connecting rods which is the only physical changes to the engine. The compression ratio is still the same at 9.4:1 but with the stronger rods, you can put a simple 6 pounds of boost out of a turbo and get another 90 HP with an inter cooler, looking at 285 HP with a 330 pounds of torque running on 91 octane. God luck and hope this helps, here is link http://cartuning.ca/about/

Inherited 96 Buick hasn't run in over a year


How do you know it needs a new starter? If the anti-theft system is activated it will not turn over. It may need a new ign. lock cylinder and chip key, as with age and use the wire that goes to the lock cylinder will break. Get battery, clean cables and change oil and filter. At sometime you will need to replace the upper-intake plenum. It will leak water into the intake port of the engine and you will trying to figure out where the coolant is going. I have seen a few of them that have swallowed enough coolant to cause the motor to cause a hydraulic - lock . People will try to crank them and will break the end on the starter due to the motor being locked. When that happens you will need to pull spark plugs and get the coolant out and replace the intake plenum. {Big plastic thing on top of engine}. Why was car parked for so long?
