How to remove/replace the Valve Cover Gaskets on a New Beetle car?


Replace the valve cover gasket if the valve cover gaskets are leaking or if they're worn. The procedure is as follows:--
1) First of all let the motor cool down if the car was recently driven. Then remove the air intake boot.The air intake boot ios attached to the engine's throttle body.
2) Carefully disconnect the throttle cable , hoses and electrical connectors located on the upper intake manifold.
3) Then disconnect the hard pipe that is connected to the EGR (exhaust gas recirculation) valve.
4) The EGR valve is located beneath the upper intake manifold.
5) Then remove the bolts from both the upper intake manifold and the manifold support bracket.
6) Now the upper intake main fold and lower intake manifold both have got loose as you removed the nut.
7) After that remove the upper intake manifold from the lower intake manifold. Carefully place clean rags over the intake runners to prevent anything from falling into the intake system.
8) Then you will have to disconnect the crank case breather valve on the valve cover.
9) Then remove the bolts from the valve cover and remove the reinforcing straps.
10) Then remove the camshaft belt cover and the dust shield from the back of the camshaft sprocket.
11) Now carefully remove the valve cover. Properly clean the old gasket material with gasket remover.
12) You can install a new gasket in the reverse procedure of removal.


This will help. good luck.

HOW TO REPLACE UPPER AND LOWER GASKET


This is going to be a pain, due to the age and rust. I assume when you say upper exhaust gasket. You are referring to the manifold to head gasket. If so you need to soak the stud/nuts with PB Blaster lube then back out the nuts, to remove the manifold. For the lower gaskets I assume you are referring to the donut gaskets where the pipes meet, I am pretty sure this model does not use donut gaskets.

WHERE TO LOOK FOR EXHAUST LEAK


There are several areas to check for possible exhaust leaks. i will list them below.

1. Exhaust manifold gaskets - This will be the most common area. There is a gasket that separates the block from the exhaust manifold. these gaskets can fail, thus, causing a exhaust leak at the manifold.

2. Lower manifold gasket(donut gasket) - This will be a possible leak spot as well. This small circular gasket is placed in between the upper exhaust pie and the lower side of the manifold. It basically separates the pipe from the exhaust manifold.

3. Exhaust pipe - The entire pipe can rust overtime, thus, creating small holes along the pipe structure. These holes will cause the exhaust to leak ,thus, filling the vehicle will moderate fumes and causing louder than normal engine sounds during revving.

4. Muffler - This component can also deteriorate to the point that it cannot filter out the noise. It will also cause leaks as well.

You will find the leak in one or all of the areas stated above in the list.

What would cause oil in coolant and leak near intake manifold?


Head gasket, if you have a V6 or a V8, can't tell which one is at fault, so both will might as well be changed.
If the leak near the maifold is oil, the valve cover gaskets are leaking.
When head gaskets are changed, all the necessary gaskets come in the gasket kit.

Blown upper air intake manifold on gm 3800 series two engine


Parts stores carry a kit including a manifold and gaskets. When I do the job I always replace the lower intake gaskets because they leak too. Make sure the lower manifold is not warped around the rubber gaskets towards the throttle body side, a new or used loewr manifold might be needed to ensure a correct repair.

Intake manifold gasket / replace


3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.
