How do i stop a leak from intake manifold gasket?

Please take your vehicle to a qualified mechanic. A leak in the intake manifold gasket can cause catastrophic results not only are you losing coolant to the outside but may also be leaking coolant internally which could contaminate the oil and cause the engine to fail due to loss in lubricating properties. Also, if not torqued properly you may have a warped intake manifold. Please see a good mechanic it may cost more but you risk a much larger cost to replace an engine

How to fix intake gasket on 2003 malibu

What is the problem with the intake, is it leaking air, coolant oil or a combination of the 3? The answer really depends on your particular concern with the vehicle. Is it the upper or lower intake? What size engine do you have?

I just fix my intake gasket on my 99 gmc

when you replaced the intake gaskets you over tightened the bolts and cracked the plastic on the new gaskets or cracked them replacing the intake on the engine or the bolts needed to be replaced cause they were stretched or the wrong gaskets where sold to you and you have a vacuum leak these are the most common causes of the problem you are explaining the newer intake gaskets are very sensitive to over tightening you really have to be carefull and follow the tightening sequence and torque specs

I have a leak in my intake gasket. any easy fixes. The dealer want $1000 to fix it.

Hello Imb.
No quick fixes I am afraid.
The intake gasket is a plastic gasket with a silicone seal impregnated into it.
The plastic cracks and the silicone seal spits out. They need to be replaced.

You could find an aftermarket repair shop that may be able to do this for you for much less.
I also recommend using Felpro brand gasket set. These use a metal style gasket that are much better quality than the GM gaskets.
In my shop the job would be 5 to 600 dollars to complete.

Hope this advise helps you. God luck with your repair.
Thank you for using FixYa.

Water running out from top of motor. Intake Gasket?

The lower intake manifold gasket will be the problem. This is a high failure rate item and GM has redesigned the gasket a couple times in an attempt to correct it. Currenty Napa has the best replacement gasket and it is known as a "Perma-Dry".
I have done many and have never seen a warped intake. It's worth the fix, take your time and torque the gasket as per the instructions provided.
Good luck

Losing antifreeze into oil.what is the problem. head gasket or intake gasket..

Hello mspayde925: My name is Roger and I will give you a answer. This could be either intake or head gasket. If it is a head gasket you should be getting white steam from the tail pipe. If it is a intake you should just have coolant in the oil. Most common is the intake gasket. GM put a plastic silicone impregnated gasket on the newer engines. Have a lot of leaks needless to say. Be sure to change the oil after your repairs. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

Intake? coolant leak

You can start by pressure testing it. Do you see it coming out by the head? Those are not too bad to fix, leaking into the cylinders or oil chanels could cause more problems. With it just leaking out you may be able to get it fixed by replacing the gasket alone.
Use a straight edge to check if the head is not warped while you have it off.
I hope this is what you are looking for.
