Very difficult, especially if you have never done one. This requires high precision tools and mechanical capabilities. You are advised to leave this one up to the professionals. Believe me, I still remember MY first headgasket and it drove me crazy back in 1969. Okay, yes, I'm getting old. Thanks, Dana.

When it comes to the actual removal and installation of the gasket it is rather simple. You need to get the engine head out to get to the gasket. You will have to be concerned about are the belts that needs to be taken out including the timing. Not to mention the weight of the head. I would recommend to check the fuel pump the belts since you will have access to these parts once you access the gasket to save labor.

Maybe... if you have never done it before.
You will need a torque wrench, and as long as the head is off, you should take it to a machine shop (at a local auto parts store - not a national chain) to have the valves ground (valve job).

It is ok to just do one side of the engine that is affected.
How sure are you that your Olds needs a head gasket change?
I would be happy to provide another opinion.

Also ... Go to your public library (you don't need a library card).
In the "Reference Section" find the Chilton's or Motor's manual for your Olds. Find the pages in the manual that explains the head gasket replacement. It will have step-by-step instructions and great pictures / illustrations and explain what special tools and torque specs.
Photocopy the relevant pages using the public copy machines (15 ~ 25 cents per page).

Study the pages and decide if you want to do it yourself.... I say "Go for it" ... we will be here to guide you along, too.... free!

    Oh, yeah .... AutoZone offers free tool usage (like torque wrench) when you purchase the parts there. Their parts prices are competitive.

    By the way, don't get discouraged .... there is an alternative ... maybe temporary or may last several years ...

    Engine Block Sealant ... $8...

    Study the pages like I said and then consider the Sealant.

    Hey, it really works, too. and consider how long you will keep the vehicle and what it is worth to you (not to anyone else).

ANSWER YES This Does Require Much Technical Skill and LABOR.
At a Service Shop A VERY ROUGH ESTEMATE Would be "AROUND" $600.00
And This is a HEAD GASKET "REPLACMENT"

Blown head gasket


Well it would really depend on the condition of your engine.
It would take more labor to repair your engine than it would to just replace it. But unless the engine is very damaged it should be cheaper to have your engine fixed. And replacing the head gasket and having the head repaired should be under the price you were given. A head gasket set for a 4 cyl engine is around $100 wholesale.
I would call around and check with other shops next.

My 1994 ford mustang blew a head gasket. I am having a hard time finding a 3.8 liter v6 engine. Is there another size engine that can be interchanged?


Well, it also came with a V-8. One of those would probably be a lot cheaper. There shouldn't be a lot of extra work in making the change over, and as long as you don't go all crazy you can still get decent mileage from them.

How hard is a head gasket repair


Extremely difficult. Usually a shop will charge 6 to 8 hours on 1 head gasket, and they have all the tools. You will have to remove the wiring, hoses, valve train, and the head, replace gasket, check for damage, re-assemble the motor and leak check. Pretty invasive

Blown head gasket


This would depend on how long you actually ran this vehicle with the failed head gasket. if the temperature was hot enough, it could have warped the heads and replacing the gasket in this case wouldn't fix it. it would still leak.

NOw, if the block head is not warped and it didn't get to hot during the ruptured of the gasket(s), you may not have serious damage to the internals and replacing the gasket would be feasible at this point.

This job can take time and is not easy at all. it will take you and another assistant to complete and it can be hard work. not easy. remember, if your Engine reached a temperature that was really high and it was driven while the gasket was ruptured, it may have done considerable damage to the internals.

You will have to break down the engine to accomplish this repair if you choose to actually replace the gasket(s).

Please rate and god less:)
