Will a bad upper intake manifold gasket on a 97

You have either a bad head gasket that needs to be replaced ASAP or possibly a cracked head (more expensive). If you continue to drive or run the engine it will suffer crankshaft bearing failure. If the intake manifold is a "wet" type (coolant goes through it for any reason) that gasket may be leaking and letting water in the oil. But I'm leaning toward a new head gasket.

In either case, water is entering the combustion chamber.

You don't say what the make model and year is, but yes it could be an intake gasket.
It could also be a leaking head gasket among other things.

One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Hi,
White smoke usually indicates a blown manifold gasket or head gasket. First, check for coolant in oil. When you pull the dipstick, is the level too high or have a foamy appearance? If so, blown head gasket. If not, spray starting fluid around intake manifold outer mating surface with engine running. ( not near throttle body or air intake) If motor revs up during procedure, locate that area you are spraying and duplicate the motor rev up. If consistent, blown intake manifold gasket. Its always good to have codes checked first if you have a check engine light illuminated....Mike

HI. This will be the cause of coolant consumption that is occurring at this time. I will list the most common culprits below.

Coolant consumption::: Possible causes______


1. Check the head gaskets. The gasket may be leaking, thus allowing coolant to leak into the combustion chambers.

2. Check The Intake Manifold Gasket. This gasket may be leaking, worn, or damaged

3. Check the cylinder head for worn or scorn cylinder block.(This will require total breakdown of the engine)

4. Check the water pump seal for leaks as well.

Now that we have covered the basic check points for coolant consumption, i would advise to concentrate on the head gaskets if there are no apparent leaks on or around the engine itself. If the head gaskets are worn, the leak can be introduced to the engine internally, causing the engine to burn off the coolant. this is noticeable by removing the oil cap, after a hard drive. you Will notice steam that will escape the head as soon as you remove the cap. If this is the case, your problem will be with a failed head gasket.

IN a severe case, you will notice white plums of smoke escaping from the tail pipe during acceleration

Oh no! I'm sorry to tell you this but it's serious. That white smoke is actually smoke and steam. Check your radiator for oil. White smoke is indicative of a blown head gasket. If you are mechanically inclined you can try to repair it yourself, but it's a huge job. As a matter of fact, some cars, if you can't repair yourself, some people have to junk it. What is required to fix this is an entire breakdown of the top side of the engine. Throttle body, intake manifold, exhaust manifold, spark plugs, emissions, valve covers, overhead cam<-I believe it's overhead, if not, rocker arms, pushrods and lifters. Remove the head, take it to a machinist and have it steamed and milled. Buy top end rebuild kit. If you are going to replace this head gasket, you may as well rebuild the top end. You actually could try a salvage yard and buy an entire engine and have it delivered to your garage of choice and pay to have it put in. Sorry for the bad news. If you continue to drive it temporarily, just remember that you are losing oil into the radiator and coolant out the exhaust pipe. Check and fill it daily as necessary.

usually a sign of a blown head gasket or intake gasket or, gulp a cracked head or block. Check your engine oil for a milky color, This would confirm a blown head gasket. There is a test to determine if hydrocarbons are in your coolant. If your coolant level is low or empty, this is another sign.

Hi: What Color is the Oil coming out of your Tail Pipe? I'm Assuming its Motor oil and not Transmission Oil.Since you found white looking substance in your oil It sounds like you have a Blown Head Gasket or both.And could be a Crank Block or Head ,Pull your Spark Plugs out, And Have someone Crank engine over and see if you are getting that white Substance Which i assume is Motor Oil.If you are getting ANY out of ANY Spark Plug hole then Is fair To Say you have a Blown Or Cracked Head Gasket.THERES only 1 Other Alternative On Older Vehicles than Yours is ,They Had what was Called a Vacum Modulator That Attached to the Auto Transmission, I worked off of Vacum From The Intake Manifold,And if the Diafram in It went Bad it would **** Transmission Fluid up Through the Intake Manifold and Burn It through your Intake and would come out tail Pipe as a WHITE SMOKE,But it normally would not be in the Enging Oil Or Radiator.So i Would 1st Check the 1st Advise i have Given You.Pull The Spark Plugs. Hope This Helps.Please REply by Voting if this Helped Youat All,Thanks From the WYOCWBOY

You are loosing coolant. White smoke only comes from water. Gray or blue from oil

No secret here, intake manifold or head gasket.

the gasket you had replaced was the lower intake manifold? this gasket can leak coolant and cause white smoke to come from the exhaust. the exhaust is actually single with dual outlet at muffler. when an engine is getting coolant into the cylinder it burns and causes white smoke much like steam. if the engine is running rough and has the check engine light on then it sounds like you have either a leaking intake manifold or problems with the cylinder head or heads. head(s) could have a bad gasket or a crack. only way for sure to tell is too remove manifold or head(s). call the repair shop and demand to have it looked at again. also have another totally separate repair shop inspect it to have a second opinion.
