Ford F-350 white smoke from exhaust and engine stalls during deceleration on Ford F-350

Some Ford F-350 owners report experiencing white smoke from the exhaust, which may indicate issues such as a leaking intake manifold gasket, a faulty EGR cooler, a blown head gasket, or a cracked cylinder head. Excessive white smoke during startup or acceleration can also be a sign of internal leaks in the EGR cooler or stiction from sludge build-up in the injector. While some white smoke on cold starts is normal, excessive amounts may point to problems like inoperative glow plugs, loose injectors, low compression from worn rings or bent connecting rods, or coolant leaking into the cylinders. Additionally, some owners report engine stalling during deceleration, potentially related to engine/pump timing being out of sync or high vacuum conditions causing oil to be sucked into the intake and burned. It is recommended that affected owners seek a thorough diagnostic check from a qualified mechanic or Ford service center to address these serious issues promptly.
