Our latest DeVille engine job can be seen below...


The powertrain was removed and completely disassembled.  All 20 head bolt holes were drilled and tapped to accept the NS300L inserts.  The lower case half and oil pan were resealed, using the updated GM repair process.  The cylinder heads were inspected and cleaned, all of the necessary gaskets and seals were replaced, as well as fluids, filters, and spark plugs... resolving the overheating and oil leak issues, and providing many trouble free miles (12 month/unlimited mile warranty included).
The head gasket job runs $1,500 labor, plus parts.  Bill totals being $2,000-$2,200.



We have been very successful at installing the NS300L inserts, also known as the Norm's Insert (see website link below). The other option is to install studs instead of inserts at an additional cost; these are known as the Sure-Grip head stud kit (see website link below).
