1998 Cadillac DeVille Q&A
1998 Cadillac DeVille Question: 32 valve northstar
It sounds like a blown head gasket. Please have a qualified technician confirm this! Also, if you decide to have the repairs done be sure the shop has experience with northstar head gasket jobs. It is not uncommon for the bolt holes in the engine block to be damaged and require repair. Make sure there are no overheating issues after the head gasket repair is complete. Overheating the engine is the number one cause for head gasket failures. - Russ
