NHTSA Complaint #11488379 — 2000 CHEVROLET VENTURE

In January 2022, I noticed white smoke coming from the engine and a mechanic said it was the water pump that needed to be replaced, so I have it replaced. Recently, I noticed the same white smoke coming from the engine and took it back to the same mechanic who installed the water pump. The mechanic said it was the intake manifold that caused the white smoke. I decided to take it to another mechanic to see if the first diagnosis was correct and that mechanic confirmed the first mechanic's diagnosis and my previous experience with another GM vehicle (1997 Vhevy Lumina) that had the exact same problem: water pump went out and intake manifold also started to fail until the Lumina's engine was fried.
