intake manifold

After months of dealing with vacuum leak symptoms I finally found a vacuum leak on the intake manifold. The leak is located on toward the front of intake runner #1. A description of the symptoms for anyone who finds this through a search: High idle between shifts. The idle returns to...

i believe it is the intake manifold gasket, because it took so long to crank i’m assuming it was pulling in a ton of water/antifreeze i though i did a pretty good job of installing it but i guess not, brand new head gaskets as well. any tips for when i redo this gasket (probably this weekend) i...

Hey y'all, new here, need to find an answer to something I can't seem to find anywhere else. Is it possible to swap the newer intake manifold from the 2004-2011 2.3 Duratecs onto the older 2002 Duratec? My swirl flaps are pretty chattery and the plug on the front fell out last week so now it...

I’m looking into gasket kits right now I found a Fel-Pro kit for $208 is that a reasonable price?? I noticed other kits by them were a lot cheaper but none that would fit my engine, if anyone as any recommendations let me know. Being that I have the engine out and on stand I figured now would be...

So, I’ve done some work. RV Camshaft Bored +40 4 hole injectors Cat delete Headers Small stroke (idk where the machinist found the crank, but he did.) I’m also running Advanced Timing and driving on 92 octane, it runs like garbage on anything lower than 92. Now, I’m assuming I’m needing to...

Hello! I'm new and looking for help getting the fuel rails off my ranger. I got the intake manifold off (see pictures). There are 4 complex hollow pipe like screews(see picture) next to the 8mm bolts for the fuel rails. I can't remove the pipe screws. I have loosened 3 of themcompltely and they...

Hey Folks, The Vehicle: 2003 Ford Ranger Edge, 4.0 SOHC The Question: There is a port on the forward right side (passenger side) of the intake plenum (manifold) where the PCV elbow and hose is attached (the PCV valve is on the rear of the left valve cover). Should I get full engine vacuum...

Hi guys, I've been dealing with a major coolant loss in my 96 xlt for about a month now. I bought the truck off of craigslist about four months ago and have been upgrading stuff since then, but am at a loss as to what's going on. Recently, I put in new gaskets on the lower manifold, valve...

I was got caught up in some deep water and stalled out. This happened twice, only the second time when we finally got it started there was a loud ticking from the manifold area. the second time i came in a little fast and splashed quite a bit, which is why i think it could be intake manifold...

ok guys i had the infamous timing chain tensioner issue on my ranger and now im in the process of putting it back together but i cant remember where one of the hoses goes. its on the passenger side and it goes into the intake manifold. there is a coupler looking thing and there is 2 small hoses...

Within the next day or so, I'll be replacing the intake manifold gasket. The truck had been running poorly for a while; after a few hundred miles of horrible idle, the hissing noise and a can of carb cleaner pinpointed the problem. I'd already replaced fuel filter, air filter, pcv valve, and a...

Ok, first off i have a part that is leaking coolent which i cant identify. Its a round piece connected to the top radatior hose which the hoses "y" off at the top. It circular with a rubber gromet and a metal lever at the bottom that you can physically touch and switch back and forth...its right...

Does anyone know the recommended torque for the fuel rail to lower intake on a 1999 ranger 4.0? My chiltons manual lists varied settings for other engines but this application is not even listed for the vin X model. I wonder if the Haynes manual is the same. Thanks in advance.
