It's been over 2 months and 900 miles since I swapped a 2000+ 3400 heads, intakes, injectors, fuel pressure regulator, and throttle body onto my 1997 3100 engine. I'm happy with the MPG (from 26 to 31-32 mpg) and performance end of things. The engine does not miss, studder, shake, shimmy or overheat...BUT.......
Since this swapp there has been an off and on odor of anti-freeze coming from the interior vents since the swapp and i've added about a quart of anti-freeze over the 2 months. I start to smell it just as the temperature gauge starts to rise to operating temp of 180.
Have i got a leaking heater core maybe?.....Tom
