Can someone help me with a 1995 lexus es300 3.ol v6 vacuum hose reconstruction

The pulse damper vacuum hose on a 2001 Mazda Tribute V6 3.0 connects to the intake manifold. Look for a small vacuum hose coming from the pulse damper and follow it to the intake manifold. The intake manifold is typically located on the top of the engine and will have a series of hoses and cables connected to it. The pulse damper is typically located near the fuel injectors and fuel rail. Make sure the hose is connected securely and in good condition, as any leaks or damage can cause issues with the engine's performance.

where is such a simple word
where;
3.2L V6, SOHC head 6VD1 (not the 6vd1w twin cam heads)
x marks the spot
asked many time here, and same answer.
if you look , you see it, then see its not possible to get to the 2 rear bolts (telling you what?)
pull engine block, ? no
pull intake, yes.

check that you replaced the vacuum hose from the manifold to the actuator on the transmission
check that you have not caught it under the manifold and pinched it

Intake manifold and carb replacement. I will try to walk you through this from memory as its not that hard.

• Remember to replace gaskets for carb, intake and related components like egr valve etc.
• Loosen and remove fuel lines, electrical connections, vacuum hoses etc that are either in the way, or connected to the manifold itself. Unhook the battery to make sure there aren't any unexpected sparks. The more room you provide yourself the better, remove radiator hoses/thermostat housing from intake.
• Loosen the distrubter cap and set aside, try not to remove the plug wires, if you do, take note of where they go. take note of the position of the rotor button, might want to place a mark with chalk or fingernail polish on the dist. to mark the rotor position. Lift out the distrubuter using a twisting motion. (goes back in same way with twisting motion, if rotor is not lined up, remove and try again, you might get away with it being close, as you can adjust dist. to put it exactly back in time during install, but this will be much later)
• remove the carb and linkage, and all carb related springs and hoses, mark or remember locations.
• with dist. and cap out of the way, and all electrical connectors off or out of the way, and vacuum hoses removed or out of the way, and with carb removed, remove the bolts holding manifold to engine. Genlty pry the intake up and off of the engine. it may seem stuck. Pry it loose make sure not to gouge or deform any mating surfaces like your heads.
• Now you have carb and manifold removed. Installation is reverse of removal, but make sure to clean off all the old gasket material from the heads.

Here is a picture you might use to help see what needs to be removed, basically everything on top of engine.


Sometimes on smog/emissions engines I found that there is some sort of pollution device in the rear between the exhaust manifolds that comes up behind the intake manifold and is connected, eventually by hose, to what I believe is an air pump. The hard metal tubing is between the oil pressure sensor and manifold and doesn't have any play to move it out of the way, in this case i just saw off the stud to gain enough room to remove the manifold.

if im not mistaken the number 3 coil is on the right hand side of the motor so you will need to remove the intake manifold to gain access to it.
Intake Manifold Removal

1. Remove the engine cover (if equipped).
2. Remove the air filter outlet pipe.
3. Remove the positive crankcase ventilation hose.
4. Remove the air cleaner resonator.
5. Disconnect the throttle body electrical connectors.
6. Disconnect the electrical connectors.
   
7. Detach the vacuum hoses.
   • Press the retaining ring. (1)
   • Detach the vacuum hose. (2)
   
   
8. Disconnect the vacuum hose.
   
9. Detach the injector harness electrical connector from the intake manifold support bracket.
10. Remove the intake manifold support bracket.
    
11. Detach the engine wiring harness bracket.
    
12. Detach the intake manifold support bracket.
    
    NOTE: Remove and discard the O-ring seal.
    
13. Detach the throttle body.
    • Remove the retaining bolts.
14. Remove the intake manifold.
    • Remove and discard the intake manifold gaskets.

Disconnect the negative battery terminal. Disconnect the wiring connectors to the air cleaner, Mass Air Flow sensor, EGR vacuum solenoid, and DPFE sensor. Remove the air intake assembly (up to the throttle body). There are two vacuum lines from the EGR vacuum solenoid, find where they reach the EGR valve and the intake manifold, disconnect them at these points. There is a rubber hose coming from the firewall to the top of the engine, disconnect this and push it aside. Remove the nut directly below this hose (this nut holds the bracket that the DPFE and EGR vacuum solenoid are mounted to). Follow the mounting bracket around and remove the smaller nut holding it on. Have some tape ready to mark two hoses. Make a note of which hose is the "Hi" and "Ref" on the DPFE sensor and remove them. Remove the DPFE/EGR vacuum solenoid assembly. Congratulations, now you have access to the EGR valve!!

hoping help you!

On Lexus ls 400 the starter is located underneath the manifold of intake. The intake manifold has to be removed to replace the starter.The intake manifold located on the top, left side of the engine from the front, along with the hoses, wires and tubes connected to the manifold.Mark each connections before disconnecting.This will help you while reconnecting.The starter is fitted by bolts.Remove the bolts and detach electrical cables on starter.Remove starter from engine compartment.Then re-fit the new starter in reverse as you removed the old starter.Its not very easy job.You will require proper tools to do this.This will help.Thanks.Helpmech.

1. Detach the vacuum hose from the EGR valve.
   
2. Remove the two nuts which secure the EGR valve to the intake manifold assembly.
   
3. Remove the valve and gasket from the manifold.
   
4. Clean all gasket material from both mating surfaces.
   
5. Check the vacuum hose for deterioration and replace as necessary.
   

To install:

1. Inspect the exhaust gas passages in the intake manifold and clean as necessary. Clean the EGR valve assembly as necessary.
   
2. Using a new gasket, install the EGR valve.
   
3. Tighten the EGR valve securing nuts to 17-19 ft. lbs. (22-25 Nm).
   
4. Install the hose on the EGR valve.

6. Remove the EGR valve mounting fasteners, then separate the valve from the upper intake manifold.
7. Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold.
   

To install:

1. Install the EGR valve, along with a new gasket, on the upper intake manifold, then install and tighten the mounting bolts to 15-22 ft. lbs. (20-30 Nm) on 3.8L engines, or to 106-159 inch lbs. (12-18 Nm) on 5.0L engines.
