I want to learn how to put a head gasket set on a 96 buick riviera

The fault is most likely a leaking keadgasket or a cracked head.

Never have seen a bad factory head gasket on a 3800. THe intake will leak water into the oil though.

Likely a blown head gasket or cracked head. Head must be removed and inspected. If you have more questions, please reply.

Faster and safer to drop the whole unit from the bottom with the cradle. Replace the supercharger snout bearing and seal before you install the replacement engine and the supercharger belt. Also replace the boost valve to your transmission just to ensure your getting the proper transmission line pressure throughout your transmission.
Thank you for using fixya and be safe

You can purchase one at an autoparts store for about $20 - $25 or on ebay for $10. A haynes or chilton manual will give you step by step instructions. If you've never done this before you are looking at about 2 - 4 days of work and make sure to GET THE HEAD(S) RESURFACED. Don't try to save money by skipping this step doing so will make you do the whole thing over again.

if the bolt is hitting the frame rail or the motor mount the only thing you can do is put a floor jack under the engine to hole it and take the motor mount out and raise or lower the engine to remove bolt

malfunction with security system,wait 15 min. when this happens to see if it will start.the car should not run with this light on.there was probably nothing wrong with the fuel pump last yr.

I'm sending you starter wiring diagram for 1996 Buick Riviera, I hope this will be of some help.

Head gasket is gone...don't forget to have the head checked for cracks and warpage before putting it back on. Check it over for leaks to see if anything else needs repair before driving it again.

You have a blown Head Gasket. Stop driving the car. Only drive the car in EMERGENCYS. You need to check your oil to make sure that you are not mixing antifreeze with oil. If you are, you need to flush the engine and change all of your seals. A head gasket set costs about 75 bucks. But to hire someone to do it is expensive. It might cost you about eight hundred bucks to get and experienced person to change your head gasket. If you want to know how to do this, shoot me an email @ [email protected]. I can explain to you how to do it.
