ABOVE MENTIONED VEHICLE CAME INTO MY AUTO REPAIR SHOP WITH A VERY DANGEROUS FUEL LEAK THAT THE CUSTOMER WAS UNAWARE OF. THE PLASTIC BEAUTY COVER ON TOP OF THE GM 3800 SERIES II ENGINES MADE CONTACT WITH THE HIGH PRESSURE PLASTIC FUEL LINE GOING INTO FUEL RAIL. DUE TO HIGH MILEAGE OF THIS CAR, LINE WAS DAMAGED BY THE COVER. SINCE THEN, I HAVE SEEN 2 OTHER GM 3800'S WITH THE SAME COVER-TO-FUEL LINE CONTACT. THE POTENTIAL LEAK IS EXTREMELY DANGEROUS AS THE LEAKING PLASTIC FUEL LINE RUNS FROM THE FIREWALL AREA, OVER THE RIGHT SIDE EXHAUST MANIFOLD, INTO THE FUEL RAIL ON TOP OF THE INTAKE MANIFOLD. A SIMPLE INSPECTION & PAD BETWEEN THE FUEL LINE AND THE SHARP EDGE OF THE PLASTIC COVER WOULD BE A VERY COST-EFFECTIVE CURE FOR A POTENTIALLY SERIOUS SITUATION. THIS INSPECTION & REPAIR SHOULD APPLY TO ALL GM BADGES WITH THE 3800 SERIES II ENGINES.

DEALERSHIP ADVISED INTAKE MANIFOLD WAS CRACKED AND STARTER WAS BAD. I HAD JUST PARKED THIS VEHICLE TWO HOURS PRIOR TO ATTEMPTING TO START IT AGAIN AND IT WOULD NOT CRANK. I QUESTION WHY THEY ARE ALLOWED TO USE A PLASTIC INTAKE MANIFOLD AS THIS IS AN AREA THAT GETS VERY HOT AT TIMES. I USED TO BE A MECHANIC FOR SEVERAL YEARS AND THINK THAT BUICK MADE AN ERROR BY PRODUCING ENGINES WITH PLASTIC MANIFOLDS. I HAVE PURCHASED NEW BUICKS ON AND OFF FOR THE PAST 35 YEARS AND THIS IS THE FIRST PROBLEM I HAVE EVER HAD WITH AN ENGINE. REFERENCED IN EA02-030

ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Consequence & remedy
Consequence: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Remedy: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
