Replying to: toneyg (Feb 28, 2008 5:31 pm) If he truly has blown head gaskets on a Northstar, there is more to it than replacing the gaskets and using new head bolts. He will have to have the motor pulled. This is the only way to make the following repair because you cannot reach the rear head to do this. The heads have to be pulled. (If you do this, do both heads.) Just unscrewing the head bolts will many times damage more of the bolts, stripping the alumium threads. Then the motor has to be 'Timeserted'. This is a package which has a metal jig (which can be reused, shops that have done this before will already have this) which is bolted to the motor and all the bolt holes are drilled out. Then threads are re-tapped into the holes. Then a special Timesert insert is screwed in. Then the head can be put back on with a new gasket and new bolts, which screw into the new insert. The heads themselves usually are fine, they are almost bulletproof, there is no milling needed. Then the motor can be put back in. This is usually around a $3,000 job. The main part is labor. Pulling the motor (and transmission together), drilling, tapping, assembly and then putting the motor back into the car. Parts are only something like $500-$750 or so, including a Timesert kit and the needed gaskets, etc. When you are looking at a $6,000 car (1999 Deville), you really need to think about putting $3,000 into it. A lot of beautiful Cadillacs are scrapped because of the cost of a head job. |

| i have a 87 sedan deville that wont start .it just stoped one day .it has 90,000 miles 4.1 engine, has spark.its getting fuel. local dealer told me its proly the cam shaft .i just got the vehicle so no real history .i have tried moving the timing around i can get it to where it sounds like its going to start but doesnt. any one have a idea about this ? | |
My DTS is approaching 100,000 miles - time for tune up. What else should I expect or need other than engine tune up? Do the electronic shocks wear out like the older shocks/struts?

Replying to: walterm3 (Mar 10, 2008 3:45 am) Rotate the air in the tires. The liquid change should include the turn signal fluid. Grease the muffler bearings. What's so hard about looking at the service items in the owner's manual for the 100,000 service? The list I previously gave should cover it. I can't say much about the struts. Is the car banging when going over bumps? If so, there my be a need for struts, or other suspension components, such as sway bar linkages. If the struts are electronically controlled, there will be sensor in there that tell the computer if they are working ok. If they are not, there will be a check engine light turned on and/or a message displayed in your Display Information Condition (DIC) on your dash. |
