Supercharged 3800 Series II (L67) Question
You’ll want to use ACDelco aluminum intake gaskets. The failure with the original plastic gaskets is around the coolant passage gasket ends up cracking. Replace the plastic elbows with aluminum as well. Might be worth doing the water pump. Spending $30 that you don’t have to take it apart again.- 87GraNasty
