Is an intake gasket a big deal?
When the intake manifold gasket is not running properly, that blood and energy supply is cut off. It should go without saying that this is bad news for your car, and will have a huge impact on performance. A secondary factor to consider is the fact that the intake manifold gasket also helps to keep coolant in the engine block.
When do you use sealant with a gasket?
When using RTV gasketing, proper reassembly requires the following:
- Apply a continuous bead of silicone to the mating surface.
- Assemble parts with bolts finger tight ensuring contact is established while the silicone is still wet.
- Let set for 1 hour, then torque all fasteners to proper values dictated by the vehicle service manual.

Does intake gasket need RTV?
Please note that RTV is not to be used on the entire gasket; the gasket should be installed clean and dry. RTV should only be used on the corners of the gasket and/or stepped casting areas that have a gap. Using a small amount of RTV will fill in those areas to assure a leak-free assembly.
Do rubber valve cover gaskets need sealant?
Although valve cover gaskets don't necessarily need sealers or cements, it's a common practice to glue the gasket to the valve cover. There are a number of sealant choices, too. For this application, Permatex No. 1, RTVs or Permatex High Tack gasket sealant work well.
Which RTV for intake manifold?

How do I know if my intake manifold gasket is leaking?
Intake Manifold Gasket Leak SymptomsPoor Engine Performance & misfires.Excessive White Smoke from Exhaust.Coolant In the Oil Pan.Visible Coolant Leak.Overheating Engine.
Do you put silicone on both sides of a gasket?
NEVER use silicone on both sides of the gasket, the gasket will slip and slide all over the place instead of staying put and clamping down. Another substitute for the high tack is Copper Coat (in the copper spray can). This works really well for head gaskets since it's a light film.
What is the purpose of a gasket sealer?
Gasket sealers are used to hold the gasket in place between the flanges, reinforcing both the joint's integrity and strength. A gasket alone is often enough to complete the join, but sealant is favoured by engineers to create a last line of defence.
How to tell if intake manifold gasket is leaking?
Another symptom of a faulty intake manifold gasket is coolant leaks. Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak. This may produce a distinct coolant smell, along with steam, and drips or puddles of coolant underneath the vehicle.
What is a bar leak?
According to its maker, Bar's Leaks Liquid Copper Block Seal Intake & Radiator Stop Leak has been specifically designed to chemically repair leaks in the intake manifold and intake manifold gasket, as well as other major cooling system leaks.
Do valve cover gaskets need cement?
Although valve cover gaskets don't necessarily need sealers or cements, it's a common practice to glue the gasket to the valve cover. There are a number of sealant choices, too. For this application, Permatex No. 1, RTVs or Permatex High Tack gasket sealant work well.
Is RTV sealant better than gasket?
It is fine to use the correct RTV sealant instead of a gasket if used in the right application (oil, high temp, fuel). Not, however, if the gasket thickness is required to produce a specific amount of clearance. RTV sealant is better than primitive gaskets in most applications ie.
Can you use RTV sealant on a cork gasket?
RTV, other sealants or adhesives should not be used around the coolant or intake ports on carrier-style gaskets. New intake manifold bolts are recommended. Likewise, do you use sealant on cork gaskets? Number 2 sealants work best on cork gaskets or paper oil pan gaskets.
Do Fel Pro gaskets need sealant?

What pressure do you need to do an air leak test?
When you are doing an air leak test as described in the sticky you need to put pressure into the return line (the line that goes to the injectors), not the IP. Remember: 5 psi MAXIMUM. Any more than that and you risk putting a hole in the fuel tank or blowing the lines off. Even at 5 psi you could blow a hole in the tank if it is rusty, so be careful...
Why did I put a shield on my truck?
The shield was installed originally as cleanup for a lawsuit because the location of the fuel tank (outside the frame rail) puts it in kind of a bad place in an accident . I just left the shield off of my truck... It's your option. The tank switching valve could be causing the leak.
Can you plug a solenoid at the intake?
You could always remove the solenoid and as well and just leave the electrical connector tied up so its not flopping around.
Can you mess up an injection pump?
You can't really mess that injection pump up very easily unless you get contaminants in the fuel or change some of the adjustments so as long as you keep things clean while you work you'll be good to go.
Can you use sealer on intake gaskets?
You can use sealer on the intake gaskets but it is unnecessary. There's no possibility of a vacuum leak since this engine doesn't create a significant amount of vacuum. The only time you might consider the sealer a necessity is if you are going to run the engine underwater and even then it shouldn't be needed.
What is Fel Pro gasket?
It’s no secret that Fel-Pro ® gaskets offer the most reliable seal for any repair job. Proper installation is the key to long service life, as installation practices are changing rapidly as gasket designs advance. In the past, it was not uncommon to coat a gasket with sealers or adhesives before installing it; today, Fel-Pro offers many gasket designs with advanced leak sealing technologies built directly into the gasket. With these modern gaskets, RTV or other sealers can actually hinder the gasket’s ability to form a reliable seal, causing leaks.
Can RTV be used on intake manifold gasket?
Only apply the sealant in the manner and locations directed. Intake manifold gasket sets may contain a small tube of RTV. This RTV is not to be used on the gasket face, but rather where the bottom corners of the gasket meet the end seals to fill the gap.
Can RTV cause gasket to split?
The sealer can chemically attack the rubber sealing beads and degrade them. RTV can act as a lubricant and cause the rubber gasket to slip out of place and split, creating an opportunity for leaks. Sealants can add thickness which creates uneven clamping force since the gasket will not be able to seat properly.
Do intake manifold gaskets need to be installed?
To ensure these technologies work in the way they were designed to, these intake manifold gaskets must be installed on a clean, dry surface with no additional sealants used.
Can RTV gaskets extrude?
Also, RTV can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow. In cases where a sealant is needed for installation of a Fel-Pro gasket, a FIT® Form will be included, along with the proper sealant. Only apply the sealant in the manner and locations directed.
What is the purpose of the carrier on intake gaskets?
The carrier itself (or steel grommets inserted into the carrier) prevented over-torquing by limiting crush when the intake manifold bolts were tightened down.
What engines have high intake gasket failure rates?
Engines that have had high intake gasket failure rates include 1990 to 2005 Buick, Chevrolet, Oldsmobile and Pontiac 3.1L, 3.4L, 3.8L and 4.3L V6 engines, and 1996 to 2002 Chevy 5.4L and 5.7L V8 engines. These applications alone represent a potential replacement market of more than 10 million vehicles.
What late model Ford engines have a gasket failure?
In addition, similar problems have also been observed on some late model Ford engines such as the 3.8L, 3.9L, 4.0L and 4.2L V6 engines, and 4.6L and 5.4L V8s. Similar intake manifold gasket failures have also occurred on some 1990 to 2002 Chrysler 3.3L and 3.8L V6 engines.
Why does my intake manifold leak coolant?
After 60,000 to 70,000 miles, many of these carrier style intake manifold gaskets develop coolant leaks that can cause an engine to overheat or even fail if enough coolant gets into the crankcase. Apparently, the nylon-filled plastic used in the carrier is being attacked by the coolant, causing it to soften and deform. Eventually, this causes the raised sealing beads around the coolant ports to lose their seal and leak. The failure often occurs during cold weather as a result of thermal contraction when the metal head pulls away from the gasket.
What happens when intake manifold bolts are tightened down?
When the intake manifold bolts are tightened down, it deforms the raised sealing beads and presses the beads tightly against the surface of the head and manifold to seal the joint. Advertisement. These new style intake gaskets also had a nylon-filled plastic carrier that formed the body of the gasket.
Why did they use sealer on fuel injection?
Sealer was usually required to ensure a leak-free installation. Advertisement. But in the late 1980s and early 1990s, fuel systems and manifolds began to change. Multiport fuel injection meant the intake manifold no longer had to flow an air/fuel mixture, only air. This gave engine designers more freedom to optimize airflow.
Why does my engine have a coolant leak?
The coolant leaks on these engines are the result of a combination of factors: heat, thermal cycling, coolant neglect, corrosion and degradation of the OEM gasket. Some have blamed the coolant leak problem on the type of plastic used in the OEM gaskets.
What happens when you mate the exhaust surfaces together?
If you do put too much on the surface (and you always will), when you mate the surfaces together, the exsess is going to squeeze out not only on the outside of the intake, but also on the inside. Now you have created an obstruction in the manifold for the incoming air to fight past, causing air restrictions and possibly a loss of performance. Its the same theory as having too many bends in an exhaust system, to many bends = restrictions = loss of power.
Can you use sealer on intake gaskets?
Sealer? It's very rare that you would use any sealer on intake gaskets. Sometimes you put a small dab in the corners where it bolts to the heads on V-6 or V-8 engines, right at the "v" where the manifold meats the front and back of the head. But otherwise, it's never a good idea to use any kind of sealer on an intake gasket. I learned this way back in the 70's. But of course someone will probably say otherwise and have a good reason they suggest it. I'd call a couple repair shops and ask what they suggest. You'll most likely here "none".
Can I use RTV sealer on intake manifold?
I strongly dont recommend using any type of RTV sealer on ANY of the intake manifold parts for a few reasons (and some of them have already been touched).
Do you need RTV for felpro gaskets?
The only time you really need to use RTV is if there may be a gouge or scratch in one of the mating surfaces that the gasket will not fill. Other then that the gasket will be plenty. And if im not mistakin, felpro gaskets already come with a bead of red addhesive/sealer on them.
What to do if exhaust manifold is warped?
If the exhaust manifold is warped . take it to a machine shop and have it ground.
Do you need heat transfer from the heads to the manifolds?

Is copper coat a good sealer?
And yes, the Copper Coat type sealer is a good sealer (and what I use for metal composit or shim type gaskets). On the nonmetalic intake gaskets, I put them on dry. Maybe if it's older material...I'll get them wet in warm water, then install the manifold. Tighten the fasteners again before driving off.
