On my 2002 buick with a 3.8 there's an intake gasket set for the upper plenum that goes bad after 70,000 miles or so , there's a water jacket in it for coolant it may leak internally , maybe the head gaskets are ready to blow , is your mileage and performance dropping also ?

Thank you. No coolant in oil, trans, tail pipe or on ground. Performance great mileage great. 2004, 3.8 with 117000 miles. From what I understand a top end head and intake gasket set is in the plans for next week. Thank you for your time and info
