intake manifold

Can you all help me. First time changing intake manifold gasket and a few other things and now there are two issues. Water and coolant ran down back of motor and it also won’t start or stay running. I’m sure vacuum lines are messed up so that is part of it. Other notes: 1. Used the...

I recently bought a 2008 4.6L Explorer. I took the intake manifold off to replace the seals as well as to make room for some other work. When I went to reinstall the manifold I noticed there were two vacuum line nipples on the back of the manifold, right next to the actuator. The top nipple has...

Can someone please tell me what this round thing is and what it does? I found one in the drivers side of the engine closest to the radiator, but there is only 1. There could be another one that can go on the passers side close to the door but there was not one there. Do I need Another one?

How do I remove the fuel rail? Currently replacing the intake manifold and am puzzled by how to remove it on both sides.

*Sorry if I say something that sounds kind of wrong or weird, I'm new to doing car work and modding. I was looking into replacing the throttle body on my v6 explorer, but I couldn't find anything but gaskets and spacers. I did a quick search on the v6 mustangs from the same year and I found...

I am in the process of removing and replacing the intake manifold and valve cover gaskets on my 2002 Explorer XLS 4.0 V6. In order to clean the area under the intake manifold I have to remove the disintegrated foam insert installed at the factory. I was not planning on replacing the insert...

So on my way home from town today I went through a little dirt road ally (it was a pretty bumpy and rough road) and once I got onto the road, it was probably 20 seconds before it started making some strange sound. At first I thought it was something rubbing the fan but I checked and there was...

I just replaced the intake manifold on my 2003 Mountaineer (pta). I labeled all the vacuum lines and electrical connectors very carefully before disassembly and got it all back together correctly, but when I started it I was barely able to and it ran AWFUL. Anyone have any ideas?

Hi all, 2003 Ford Explorer XLT 4.0L SOHC V6 Right now my left side valve cover gasket is seeping oil. I heard this can leak onto the exhaust manifold and cause a fire so replacing this is fairly urgent to me. Also, the fitting that the PCV valve screws into appears to not have any...

2004 Ford Explorer V6 4.0. So, I was cleaning the throttle body with the car running using carb/choke cleaner. Had someone inside the car giving it gas and letting off while I was spraying the inside of the butterfly valve. It was working fine and then it started to stall. It was able to restart...

HELP! I have a 2003 Mountaineer 4.6L, and I seem to have the common cracked intake manifold issue. My problem is, I cannot find one ANYWHERE, except Ford dealer for $455!

So I noticed a lot of oil moisture around the valve covers of my 2003 ford explorer 4.0l. It seemed like it was coming from the rear of the engine so I checked the PCV valve. Sure enough the thing popped right out without twisting it. I removed the hose that runs up to the intake manifold and...

I'm getting ready to replace the lower intake manifold gaskets on a 1997 Mouny with the 5.0 V8 due to leaking coolant in the front driver's side. It's right at the corner, and around the most forward bolt that also holds the coil pack. Anything I should watch for? I didn't see anything in the...

I'm having a problem in my 2004 Mountaineer 4.6 with coolant leaking from the left and right sides of the intake manifold (mostly the by the thermostat housing) and think it is the upper intake manifold gasket that needs replacing. I've read a lot that these manifolds are prone to cracking and...

Last summer I purchased a 1996 4.0 L V6 Ford Explorer with a manual transmission and 135,000. Aside from a small oil leak from the valve covers I had repaired, I had no problems until the alaskan winter set in. After the temps dipped down into the single digits, I noticed startup become a lot...

Ok, so I have a 2003 Ford Explorer, 4.0L SOHC, does anyone have a step by step or tips to get the intake manifold off to replace the fuel injectors, I can't even imagine how to start taking it off, no copy and paste tutorials, I know what to do, just not how to get to anything, thanks! :salute:
