2005 Impala engine type/size
 

hi, my first post, I have found a 2005 Impala with 110K miles for $1500, it will be my first chevy in a while, my concern is the reliablity of the V6 engine (intake manifold gaskets), the vin has a "K" as the eighth character, does this signify the larger 3.8 engine? Is that prone to gasket failures as they say the 3.4 engines were, any advice is appreciated

it will say the engine displacement on the underhood identification label.


the 3.8 were better than the 3.4 but still had intake gasket and coolant elbow problems.
they have new update metal intake gaskets and metal coolant elbows that will last a very long time without issues.

my 04 3.8 s/c had leaking intake manifold gaskets, valve cover, water pump, oil pan, axles seals when I got it Never seen a headgasket go on the 3.8. Never seen a oil consumption problem. Some trans problems if not maintained.


Fixed mine and the engine runs great at 230 000 kilometers. the engine is very reliable but expect a few leaking seals, gaskets and worn suspension components.

I owned a 2001 Impala with the 3.8L and had no issues with Intake or Head Gaskets. I put 200,000 Miles on that car. The 3.8 is a very reliable proven engine.
