Volkswagen polo 1.4 TDI intake manifold

I want to install a water4gas system in my polo the problem I need to know where to connect on the vacuum system or on the intake manifold. Presently I insert a pipe from the gas system directly on the intake pipe before the intake manifold on slow revs less than 1800 RPM I do get a suction , from 1800 RPM there is no more suction but a blow action to my gas system can u pls help me.

Well, the 'T' in your model number is the answer; Turbo.

Non-turbo engines produce vacuum nearly all the way through their operating range since the engine functions as an air pump on the intake cycle to obtain the oxygen required for combustion.

The turbo, which is probably kicking in at around that 1800 revs, produces an overpressure so the engine can accommodate more fuel, be it diesel or gasoline.

Your engine and the turbocompressor, are doing exactly what they were designed for and your system (which I have personally used) not only doesn't do anything useful, is also causing a loss of your overpressure.

2005 vw polo 1.9 tdi wont start


if it starts when you pour fuel in the intake.. then fuel is not reaching the tbi from the tank..you say you put a new fuel pump on this..did you bleed the fuel lines? if not do this because there is an airlock in those lines..either you need to open a fuel line at the tbi unit to bleed it all out.. or be looking at a clogged up fuel filter..

Torque sequence for 1996 chevrolet van intake manifold with a 4.3 litre moter


Ha, you tried to fool me with the bit about a 3.5 L motor--I could find that one...here is the complete procedure from AutoZone.com:




Installation To install:
  1. Clean the gasket mounting surfaces. Be sure to inspect the manifold for warpage and/or cracks. If necessary, replace it.
  2. Position the gaskets on the cylinder head with the port blocking plates to the rear and the This Side Up stamps facing upward. Then apply a 3 / 16 in. (5mm) bead of RTV sealant on the front and rear of the engine block at the block-to-manifold mating surface. Extend the bead 1 / 2 in. (13mm) up each cylinder head to seal and retain the gaskets.

  3. Install the lower intake manifold. Tighten the bolts in sequence and in 3 steps, as follows:


    1. Step 1: 26 inch lbs. (3 Nm).
    2. Step 2: 106 inch lbs. (12 Nm).
    3. Step 3: 133 inch. lbs. (15 Nm).

  4. Install or connect the following:

    Power steering pump Alternator bracket bolt near the thermostat housing Wiring harness to the lower manifold components, including the injector, EGR valve and ECT sensor Air conditioning compressor bracket-to-the lower intake manifold pencil braces
  5. Install transmission oil dipstick tube, if necessary.

    Fuel supply and return lines to the rear of the lower intake
  6. Temporarily reattach the negative battery cable, then pressurize the fuel system (by cycling the ignition without starting the engine) and check for leaks.
  7. Disconnect the negative battery cable.
  8. Install or connect the following:

    Heater hose to the lower intake Upper radiator hose to the thermostat housing Distributor assembly and engage the wiring Ignition coil Connect vacuum hoses to the upper and lower intake manifold. New upper intake manifold gasket, making sure the green sealing lines are facing upward Upper intake manifold Manifold retainers. Tighten them to 88 inch lbs. (10 Nm) using two passes. Purge solenoid and bracket Brake booster vacuum hose at the upper intake manifold PCV hose to the rear of the upper intake manifold Vacuum hoses to both the front and rear of the manifold assembly Throttle body Throttle linkage to the upper intake Wiring to the upper intake components including the TP sensor, IAC motor, MAP sensor and the fuel meter Engine cover Air intake assembly
  9. Connect negative battery cable.
  10. Refill the engine cooling system.
  11. Start the engine and check for leaks.
