This is a safety feature to prevent the pastic intake from exploding in a backfire situation. This can occur when starting if the coil misfires. Yes you can put it back in, if it won't stay in place the upper intake will have to be replaced

Locate pcv valve.pulled throtle body nothing or valve covers


Crankcase ventilation system is used to consume crankcase vapors created during the combustion process instead of venting them to the atmosphere.
Fresh air is supplied through a filter to the crankcase, the crankcase mixes the fresh air with the blow-by gases and then passed through a positive crankcase ventilation (PCV) orificed tube into the intake manifold.
The PCV orificed tube restricts the flow rate of the blow-by gases using a 3 mm (0.118 in) (a) orifice located at the end of the tube. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase vent tube into the throttle body in order to be consumed by normal combustion.

Remove the two nuts (2) from the fuel injector sight shield (1).
Lift the sight shield (1) from the front and pull forward to disengage the rear tab from the bracket.
Disconnect the PCV fresh air tube from the left camshaft cover.
Remove the PCV fresh air tube from the throttle body.
Remove the drive belt. Refer to Drive Belt Replacement .
Remove the power steering pump retaining bolt.
With the hoses still attached, Carefully position aside the power steering pump.
Remove the retaining clip securing the PCV dirty air tube.
Disconnect the PCV dirty air tube from the PCV orificed tube.
Remove the PCV dirty air tube from the intake manifold.

Is it possible for power steering fluid to get into the engine and mix with the oil? I am loosing fluid and there are no visible leaks, the engine oil and filter was recently changed and now has turne


No, the power steering is entirely a separate and sealed system, wholly external to the engine. The power steering pump pushes the fluid through a high pressure hose into the rack and pinion-the steering gear mounted below and behind the engine-and holds pressure within the rack that enables power assisted steering. At the same end where the power steering fluid hose enters the gear will be a fitting for a return line back to the fluid reservoir. These two hoses are usually routed close together at least part of the way, some may even be held together with brackets. Leaks could develop at the pump, the fluid reservoir, or the two hoses to and from the rack and pinion, or the seals inside the rack and pinion may have failed. You should be able to find the leak-it will only leak to the outside-to check the rack and pinion for leaks, right where your tie rods come out of the gear and go to the wheels for steering, will be a small rubber boot encasing the tie rod and the end of the rack assembly-on both ends is a boot and a tie rod-peel back the rubber boot from the gear ass\'y, it should be dry. If a lot of fluid, the seals in the rack and pinion are gone. It will have to be replaced.
Hopefully you will find a leaking hose or fractured reservoir, but keep looking, air flow may be blowing the leaking fluid back and under the car. Good luck, hope it\'s not the rack and pinion.

Does the stearing column adjust?


I've never heard of that problem. But racers have to disable those steering wheel locks, so if you like, I'll talk you through it.

The way the lock works is that a pin is forced up through the steering column from underneath. The pin is at the end of a little hinged flap, and a spring pushes this flap up towards the column. When the key is removed, the flap is freed, and the spring pushes it upwards. So, all you need to do is remove the spring. That way, gravity wins, and the pin never gets pushed upwards into the column.

Removing the spring is not that hard, really. You don't even need to remove the steering column trim. Under the center of the steering column, at the end of the ignition switch, you'll find a rectangular metal piece. Drill a 3/8" hole right smack dab in the middle of it. If you aligned the drill right, a spring will fall out of the hole (or maybe just get wound up on the drill bit). Once you remove the spring, the little flapper that sticks up into the steering column to lock it should be allowed to drop, and your steering will unlock.

Of course, yours is already stuck for some reason, so I can't guarantee that removing the spring will allow the pin to fall out from the steering column. If necessary, I suppose you could try to insert a screw into the flap through your new hole, and then use the screw head to try to pull the flap down.

Good luck!

I have a 351 Windsor, when I put my hand to the exhaust tips the passenger side is blowing blazing hot strong exhaust, but the driver side is blowing cool weak exhaust. The truck will start, but will not...


Hello, I will try to answer this for you. Your truck must be one of the last models to use a Exhaust heat riser in the exhaust system. If you look at your Drivers side exhaust manifold you will see a flange at the end of this big exhaust pipe. There will be a spring and a metal pin protruding on one side of this large manifold.

Sometimes the spring and protrusion will be part of the exhaust manifold, and sometimes it will be a separate heavy metal ring with those parts on it. Either way, the function of this part is to block the exhaust on the Drivers side and to force the heat of the exhaust back to the engine. You need to make sure that this device will turn the shaft that the spring is connected to.

The spring on this device is suppose to expand when it gets hot and then close when it is cold. The internal flap will then move accordingly. At least that is the plan. It is common for the flap to seize. But you should know that part of the time, because of this part, there will be a difference in the right and left exhaust flow. If the flap is seized it can stall the engine at idle or low speeds.

Next, you might want to get a free scan at Autozone or Oreillys to check for additional problems.
I hope my solution helps you fix your truck.

I can't find the thermostat on my 1996 jetta gls


On 1996 VW JETTA,The thermostat is located at the engine end of the lower radiator hose (passenger side). If the car has power-steering, then power steering pump and mounting bracket are to be removed to get to the thermostat housing. The thermostat is at the end of the bottom hose, in the water pump housing. Follow the lower radiator hose to the water pump housing. There are three bolts that are very difficult to navigate around. The thermostat is located behind those bolts.
----------------- Thank you.

Intake manifold contains what I believe is a spring loaded valve meant to relieve excess pressure. (located right side end of intake). This valve opens constantly resulting in a vaccum leak and a rough...


The vacuum diagram below may help you identify the part, you can also use the link below to view more information and see a larger version of the diagram image. I doubt that removing the cover has any effect on engine performance. There are several vacuum system valves on your engine so it would be difficult to give advice without knowing which specific valve you are referring to. Hope this helps.
