Engine "misses" cold at 60-70mph. Dealer said coil pack towers slightly rusted, some injectors "slow". Cleaned coil towers and ran injector cleaner. Now ok. |

Intake manifold leaking coolant into oil and out of engine in general. Installed new gasket. No, this is not the plastic, but is the steel gasket. Replaced both valve cover gaskets, while intake manifold off. |

Replace both valve cover gaskets, which were leaking, at same time was replacing intake manifold gasket, that was leaking. Replaced both valve cover gaskets, while replacing the instake gasket, since easier to do both as once. Buick 3.8 gaskets leak at high mileage, 248k miles in my case. Original upper radiator hose ruptured at 242,000 miles. Replace both upper and lower hoses, plus replace thermostat. |
