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.

Engine running hot


Sounds like a possible head gasket. Check oil for anti freeze in it and check to see if exhaust smells sweet or excess moisture out tail pipe. It also could be leaking external! Check to make sure the fan is workiing also when it is hot.

Oil leaking from under the front of the motor. Have had both manifold gaskets changed, yet still have a leak. Now the starter is full of oil and I have to replace it


the manifold gaskets role in an oil leak? oil under the car i would be thinking about a front or rear crankshaft seal or the oil pan, or the oil pressure sender unit. if there is oil on the sides of the engine i would look to the valve cover gaskets.

Windstar 2000 3.8. Runs fine. Checked for codes and got p0171 and p0174. Cleaned the MAF sensor. Went to erase codes and found the there is a third one in there now. p0113. What is wrong?


The upper intake manifold gaskets and isolators (the bolts that hold the manifold down) leak and cause the p0171 and p0174. The reason they leak is due to a missing baffle in the front valve cover which allows some oil into the upper intake which swells the gaskets and wears them. The manifold gaskets and valve cover should be replaced. But before having this done check to see if the black plastic hose on the back of the rubber intake hose(between the throttle body and maf) has dislodged. This happens alot when a new air filter is installed and will cause the same codes.

Valve cover gaskets, now it wont run


You need to get the timing checked, did you mark the position of the distributor before you took it off. If not you might be slightly off with the new distrib.
