1998 Oldsmobile 88 Royale 3.8L Intake Manifold
Posted to GM Engine on 2/5/2013 36 Replies

Water intrusion into intake manifold throught upper plenum at EGR port causing water to get into cylinders. Original manifold burned out the same way. Seems like EGR is opening too long causing a meltdown of manifold. We have no EGR codes
