| 1998 pontiac montana with a gm (generic) 3.4 liter engine events leading to failure were normal driving conditions and regular maintenance. the failure is the intake manifold gasket. the consequences currently are exterior leaking coolant. *ak the probable future consequence per the dealer, is coolant leaking into the crankcase causing the failure of the crank bearings. which documented cases have resulted in engine failure while driving which can cause a unsafe situation. what will have to be done is to replace the intake gasket at a cost of $500-$700. | |||

| A well maintained 1998 pontiac transport with a 3.4 liter engine developed a coolant leak. this was diagnosed by a local service center. as they explained that my vehicle has an intake manifold leak, it was also mentioned that they have seen many manifold coolant leaks with this engine. i decided to have it repaired at a gm dealer where i purchased the vehicle. they also explained that they service many of these type of leaks. they explained that the repair calls for a new type of manifold gasket and new bolts. the mechanic even showed me where on the old gasket the failure usually occurs. although it may seem as if these comments where anecdotal, it still appears to point to a general failure in the design of the manifold gasket. this repair was very expensive. why haven't these 3.4 liter been recalled? are only inexpensive manufacturer defects recalled? had this coolant leaked into the engine which in some cases it does, based upon my research of this issue, then even more damage and possibly risk to the vehicle operator and passengers could have occured. *ak | |||
