| AT 54K MILES THE INTAKE GASKET REQUIRED REPLACEMENT ON A 1999 PONTIAC MONTANA WITH A 3.4L ENGINE. HAD BEEN TOLD THAT IT HAD BEEN LEAKING COOLANT OUTSIDE THE ENGINE BLOCK FOR SOME TIME. LOCAL CERTIFIED MECHANIC PERFORMED GASKET REPAIR STATING THAT HE HAS REPLACE MANY GASKETS ON THE GENERAL MOTORS 3.4L ENGINES. MORE THAN HE COULD COUNT. THE BOLTS HOLDING THE TWO PIECES OF THE ENGINE TOGETHER WITH THE GASKET BETWEEN ARE FINGER TIGHT IN MOST CASES. I HAVE OBTAINED A PRESENTATION FROM GM POWERTRAIN EXPLAINING WHY GASKETS LEAK ON THE 3.4L ENGINE. PRESENTATION SUGGESTS MODIFICATIONS TO THE GASKET AND TO BOLT TORQUE SETTINGS. I WAS TOLD BY THE ABOVE MENTIONED MECHANIC THAT THERE IS A MORE ROBUST GASKET FOR THE REPAIR ALONG REVISED TORQUE SETTINGS FOR THE BOLTS AND SUGGESTED APPLICATION OF LOCTITE TO THE ENGINE BOLTS TO PREVENT THEM FROM BACKING OUT. | |
