I have a headgasket problem on a 98' seville. I want to replace the whole block. Now what do i do to remove the engine. Any thread or site that can point it out clearly would be the best. swaping the motor would be the easiest way or we might actually get new head gaskets, and bring the motor to a machine shop for rethreading and screws.

Hi, we have the same problem with the engine removal. I subscribed to alldatadiy.com (26.95 for the year) and it does give step by step directions for the engine removal; or anything else that needs to be done. I'm printing the pages out right now.
I actually wrote in last night the SAME time you did.

good luck on your "project".

You don't need a new block. A set of Jake's studs, Timeserts, or Norm's Inserts will reapair your block threads, same as in any other Northstar block. Jake's studs would be preferred.

The entire drivetrain needs to come out the bottom of the car......you raise the front on jackstands unhook everything from the strut tower tops to the brakes to the exhaust to the electrical system, and lower the whole unit, then lift the body off and roll it back. Not fun - tedious if anything. Read all posts by Tateos on his work.

Use the search button up in the blue bar - there's a lot to read and see on engine removal.

The easiest way is to drop the cradle by lifting the body off. This makes it very easy to work on the engine.

If the car ran well except for the HG's then just repair the HG's! Don't buy an engine you cannot hear run if you can avoid it. Kim psummit has bearing problems so that's different.

If you can remove the engine you can do the inserts. They are very straightforward, just tedious because you want to do all 20 of them.

There are other threads with tips and more pics, that's just mine.

Now i am interested in paying the 20 bucks at alldatadiy.com
But do they have any pictures of how to remove it? Also does it include all the torque settings for the bolts/screws??

I will not lie to you dave the alldatadiy version of removing the motor is pretty vague but it is great for torque specs and things, Tateos and Zonnie77 both have very good threads and I am putting together my own that will be live this time next week, I am basically taking pictures of each bolt, nut, etc. before I remove it and I will do a small description to go along with each picture, so if I where you I would start "doing some homework" with tateos and zonnies threads they are EXTREAMLY helpful, and hopefully my thread will prove helpful as well.

as to replacing the whole block it is really not necassary, Jakes stud kit is all you need (www.studkit.com)

I dont believe there is a way to disconnect the fuel lines without a tool, but I got the tool from autozone for 6 bucks

I'm not sure either. I know the 3800 calls for a special tool. I bought it and found it easier to do with pliers.

tateos, I looked into your thread a bit. Now after turning the bolt, you need to turn it with the correct torques, but switch torques after a certain degree, where can i find the exact settings? Also the torque for the other bolts, Service manual perhaps? Like in your threa, i dont want to under torque it because of oil pressure problems.

Some bolts are tightened to a set torque as: Tighten sequentially, increasing to xx ft/lb. Others are torqued to a beginning xx ft/lb and then further tightened in 2 or 3 steps of say, 30 degrees. There's no set torque for that kind of procedure: the first torque step sets all the bolts on the assembly to a constant and the following degrees of tightening stretches each bolt equally.

We got to the point where can almost drop the engine. We just need to disconnect the steering, What is the best way to disconnect this?
Also i read that everybody has problems removing the crankshaft. My question is if you are facing it do you turn the wrench clockwise or counterclockwise ??

Are you talking about the crankshaft dampener? Right = tight, left = loose. "Righty tighty, lefty loosey".
