Most vacuum leaks are in hoses that are disconnected or have holes in them you can also take a bottle of water and spray it along the side of the intake and base of the carborater if the motor bogs or you here it **** the water in you have found you leak but it can be a leak under the intake and that is a bigger problem to find

  3. Install the valve cover to the cylinder head, and tighten the bolts to 71 inch lbs. (8 Nm).
  4. Route the spark plug wires into the retainers, and install the plug boots to the spark plugs.
  5. Replace the intake manifold and the intake plenum.
  6. Connect the negative battery cable.

INTAKE MANIFOLD REMOVAL & INSTALLATION

3.0L Engine
This vehicle uses a sequential multiport fuel injected engine. Fuel injector connectors must be positioned onto their appropriate fuel injector or engine performance and exhaust emissions may be seriously affected. Fuel injector connectors are numbered to match their cylinders.
  1. Remove the intake plenum.
  2. Properly relieve the fuel system pressure.
  3. Remove the fuel supply and fuel return hose from the fuel rail.
  4. Fuel injector electrical harness connector.
  5. Remove the intake manifold bolts and the intake manifold.


NOTE Mask off the ports to the intake manifold spacer. If foreign objects enter the engine, severe damage may result.
Clean the intake manifold sealing surfaces with a non-abrasive tool or solvent.
Do not damage machined aluminum surfaces or improper sealing may occur.

I keep getting a notice that the #2 and #4 cyclinder is misfiring. I went to change the plugs, but could not locate them from the top of the engine. Where are the plugs located at?


Need to remove upper intake manifold to reach valve cover close to firewall. 1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires). 2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold. 3) Loosen all the bolts holding the manfold. 8mm socket-- I think three in front and three in the middle. Remove the EGR valve mounts so you can slide the manifold out. Disconnet all vacuum lines from manifold and the air filter inlet closet to manifold. Just take a general look and ensure you have all wiring and tubing disconnected then slide the manifold off the eng and EGR valve. NOW MAKE SURE you cover all intake holes (leading into the engine) with paper towels to prevent droping screws etc into the engine. Then follow step 1 above

How to change out valve cover gaskets on a 1989 Lincoln Town Car


This is All you need for this Repair, ALSO Be Sure ALL GASKET SURFACES ARE VERY CLEAN. This Engine Requires MORE than MOST ALL Engines do for this Repair.

REMOVAL

  1. To remove a valve rocker arm cover from the RH cylinder head, disconnect PCV closure tube from oil fill stand pipe at rocker cover.
  2. Remove the Thermactor bypass valve and air supply hoses as necessary to provide clearance.
  3. Disconnect the spark plug wires from the spark plugs using Spark Plug Wire Remover T74P-6666-A or equivalent. Do not pull on wire. Remove the wires and bracket assembly from the rocker arm cover attaching stud and position the wires out of the way. ALSO MARK THEM AS TO WHERE THEY CAME FROM !!!
  4. Remove upper intake manifold.
  5. Remove attaching bolts and remove the cover.
INSTALLATION

  1. Clean the valve rocker arm cover(s) and the cylinder head gasket surface(s). Position a new service valve rocker cover gasket.
  2. Position the cover(s) on the cylinder head(s). The cover is tightened in two steps. Tighten the bolts to 14-18 N.m (10-13 lb-ft). Two minutes later, tighten the bolts to the same specification.
  3. Install the crankcase ventilation tube in the RH cover.
  4. Install upper intake manifold.
  5. Install the spark plug wires and bracket assembly on the rocker arm cover attaching stud. Connect the spark plug wires. Install the air intake duct assembly.
  6. Install the Thermactor bypass valve and air supply hoses (if required).

How do you get to the rear plugs on a XG 350, 2002


Yes you need to pull the manfold to replace the back three plugs. No you do not have to drain water or oil. Use a good double platum plug. While your there replace the three wires. You do not need any gaskets if your cearfull. Good luck

Oil coming out of the intake manfold, what is the cause 1.9 volkswagen tdi


You can try to replace the PCV valve. Usually this problem means worn or broken oil rings, engine valve stem seals, or an oil passage leaking at the head gasket. You can try checking your spark plugs to see if any are fouled.

Check the backside bottom of the carb. there's a vacuum port there. Make sure it's plugged up. How's you timing? Also try rotating distributor back and forth. It may be a timing issue. Not enough or too much.
