How much does it cost to replace a head gasket for a 97 Cadillac Deville?

December 26th, 2010 · No Comments

- It will cost between $1700 (independent shop) and $2300 (dealership) depending on where you take the vehicle to be repaired.
- If a Northstar isn’t done right you’ll screw up the block by pulling the head bolt threads out.They have to be drilled out and steel inserts installed.You might want to consider replacing the entire engine with one rebuilt by Accurate Engines.They’re one of the best in the business at rebuilding the Northstars.
- A lot. Its a very complex engine and it can be difficult to do while the engine is in the car so many mechanics want to take it out. This also gives them a chance to look for and repair other damage. The other thing that needs to be done on a Northstar is it needs thread inserts put into all the bolt holes. Often times the threads come out with the bolts. If they dont they likely will when you try to torque them down.
