How to Remove Nissan VG33E Upper Intake Plinum Manifold. Part 1/2

- This is the first step in solving many coolant and air vacuum leak associated with the Nissan Vg33e engine. that is removing the upper intake plinum(acoustic) manifold. Most of the time a coolant leak may not appare to the eyes, since the coolant will become steam from hot engine. The intake gasket joint seal air and coolant from exchanging location passage. the lower and upper intake manifold gaskets will become faulty to leak air and coolant. this video shows you how to remove the upper intake manifold to address many problem below in the engine valley. its also require removal to service the left side valve rocker cover gasket joint, which always leak due to excessive heat that deteriorate its rubber gasket joint. Below the intake plenum manifold are a few metal tubes connected by rubber hoses to provide coolant to the throttle body, for cold(below 68°F) and all the time when engine is running. The coolant passageways will start leaking fluid. The more and other tubing is for the PCV valve. The video is also in part of showing, how to remove the fuel pressure regulator valve from the Nissan vg33e engine. Also, How to remove fuel injectors, injector fuel rail and how to change injector o rings.

Thank you for reposting this! Your videos are awesome - helps keep my 2004 Xterra alive at 245k miles!
I'm at 189k miles. 😀👍
Amazing how your Torx bolts and sockets look like Allens.
Nevertheless, thank you for the instructions anyway. It's MUCH needed.
How did u get the c clamps off the coolant hoses in the back? I'm stuck at that part at the moment 😭
Wow, cant believe you found this crappy channel. You need a long needle nose plyers to reach in that tight spot to get of the clamp. Good luck
Yeah same thing here
A stuck plenum bolt that's stripped inside can be removed by hammering the living sh*t a 12mm socket on to it. The bolt metal is cheap and will conform to the socket giving you something to grab onto and turn.
Wonderful video. Thank you.😊
Nice. I have a part on the top of the plenum, directly under the throttle cable pulleys, that I cannot seem to identify with online sources. It has a short 1" shaft that points toward the air box, and there's a device connected to it above it that seems to move it slightly, with a spring coiled aroumd it. It appears to be part of a circulation system, or is opening something. Oil is leaking from it, about 10 drops every 45 minutes of idle. What is this part and why is oil way up there?
This is a brand new to me 1998 Pathfinder with 3.3L 4x4. 167,000 miles. No codes other than P01400 EGRC error. But runs great.
Thanks if you can help. I have a picture I can direct you to or email.
You can see the part at 6:20 of your video, right under the throttle pulleys.
The channel had a video on that topic of your concern but UA-cam Google deleted it. Its is most likely coolant leaking for the thermo-solnoid below the throttle body. It can be stop by doing a bypass to the two coolant hose that goes up to intake plenum at the rear of the engine between the firewall. The thermo-solnoid is a mechanical temperture adjustment for throttle intake air adjustment when the engine is extremely cold to help fast idle the engine till it reaches operation temperature. It's a technical and difficult part to dissemble and repair with proper adjustment. There is no way oil can be leaking from the throttle body unless its blow-by oil from inside the intake plenum manifold. You will need to remove the intake hose from the throttle to see if its oil buildup inside the plenum leaking at the intake hoes joint. If that is the case, replace the PCV valve and clean out the valve cover air breather plumbing. Good luck.
@@SteveXNYC that's what another guy said on a forum, about the part being the thermo solenoid, and that it should be coolant if anything is leaking. It is definitely motor oil. It has gotten worse since I did four or five 45 to 70 minute idle tests with a few 3,500 rpm revs for 30 seconds at a time. How would the pressure and oil build up that much there and get into a spot that coolant is meant to flow? It is definitely not coolant, and is motor oil. 6 to 10 drips every 45 to 70 minutes of idling.
I will check the PCV valve. A mechanic just put this together and checked everything over as he did it, so hopefully the PCV valve is just clogged and he missed it. Thanks!
@@SteveXNYC and thanks!
This looks like it was recorded in the 1960s
