I do about 4 to 6 a month at our shop. The main problem is not the Dex-Cool in most cars. The problem is a combo of the intake gasket design (plastic gaskets) and the low torque the intakes torque at. Fel-pro and GM both have a revised intake gaskets for the 3.1, 3.4, 4.3, and 5.7 engines. They are a metal design gasket with bonded rubber around the water outlets and ports. We have had excellent luck with these gaskets because they hold the torque setting so much better. We have one set on our 4.3 stocker that have been reused 4 times. The Dorman intake for the 3.8 is a great intake for replacement.
