Third GM with intake manifold leaks. 1
4.3, and 2, 5.7 vortecs. GM knows this
problem exists. ASK ANY DEALER. Sun
Crashes dashes. Two water pumps, one on
4.3with 47000 miles, one on 5.7 with 50M
Rattles in dash. Gas mileage on 5.7 is
excessive. New tune up may get 15...
Heater hoses are poor
Powerful in all engines. Grillwork is
beautiful. Appearance is not an issue.
Have 5 GM's but beginning to think about
TOYs and Nissan. Watch out when they
increase engine size (torque).
Put more than 8 bolts in the INTAKE
MANIFOLD!!!! Do something with those
quick disconnect heater hoses
