To repair an engine manifold, various sealants and adhesives can be used as seditives, including high-temperature silicone gasket makers, epoxy adhesives, and specific manifold repair compounds. High-temperature RTV (Room Temperature Vulcanizing) silicone is commonly used for sealing gaskets and joints due to its ability to withstand extreme heat. Additionally, aluminum or metal-filled epoxy can be effective for repairing cracks or holes in metal manifolds. Always ensure the selected product is compatible with the materials and operating conditions of the engine.
It is the area of the engine where the fuel and air go into the engine. It usually hasthe fuel injectors connected to it. It is bolted to the engine. An intake manifold is used on most vehicles. The intake manifold delivers theair & fuelmixture to the combustion chambers of your engine for ignition.
The MAP sensor in a 1986 2.9 liter engine is a manifold absolute pressure sensor that measures the pressure inside the intake manifold. This information is used by the engine control module to calculate air/fuel mixture and ignition timing for optimal engine performance.
With any car, it would be better to buy a new engine. You do not know where the used engine came from and how long it will run. Unless you have a very trusted repair person, a new engine is recommended.
Don't try to repair. Replace...This item is critical to engine life. At least get used from salvageyard.
the O2 sensor is in the exhaust manifold leftside of engine (front) between engine block and engine cooling fan. Easy access. I used a 7/16.

usually spilled fluids used in the repair on engine or exhaust parts. If it does not go away after a few drives then the repair was bad.
Yes glycol (used in anitfreeze) is flammable
There are two sensors, one before, and one after the catalytic converter. There are wires coming out, so they are hard to miss. The catalytic converter is connected to the exhaust manifold, which is connected directly to the engine. You can see it looking down at the open hood, towards the front of the car, attached to the engine. The top sensor sticks stright out of the exhaust manifold, the second sensor is down a little lower and to the left if you are facing the car from the front. Note: The exhaust manifold has a metal heat shield over it. You can remove the two bolts (12mm) holding the heat shield to inspect the exhaust manifold. It is VERY COMMON for some models to develop hairline cracks in the exhaust manifold right around the oxygen sensor (you might have to brush away rust to see the cracks). This could result in the check engine light going on indicating bad cat (even though there may not be anything wrong with your cat OR your sensors!). If you see cracks, either repair them or replace the manifold (unfortunately you typically cannot buy just the manifold, you have to buy a new cat with manifold - but you can sometimes find used manifolds or aftermarket cat+manifold for cheap). Some have used heat resistant expoxy to repair the cracks (welding is better though). If you use epoxy, look for a brand specifically made for exhaust systems. "JB Weld" epoxy from your hardware store may work for a couple weeks but is not a good solution.
over $500 because they don't repair it they buy another used one and throw the old one away and say they repaired it. trust me, i work for an exhaust shop
The number 18436572 on an engine manifold typically corresponds to a specific production or design code rather than a year. This number is often used by manufacturers to identify engine configurations or components, especially in GM engines. To determine the exact year associated with this number, you would need to reference specific manufacturer documentation or databases related to that engine model.
Tha is not as much a repair as it is a rebuild job. The crankshaft is in the bottom of the engine and it's best to remove the engine for that kind of repair. Next then is buy a rebuilt or good used engine to put back in if you're going to keep it. Otherwise - go to the library and check out a motor manual and learn something about rebuilding engines.
