Well, tighten the valve covers down, just so the bolts are nice and snug on them. These kinda last how long they last, they are different for all cars. Maybe 60k to 80k, if you are lucky, they should be pretty easy on most cars to change. Use rubber bands to hold the gasket to the valve cover, in the bolt holes.
A/C, get a mechanic, these systems have a high pressure side, and a low pressure side, and if freon blows up on you, if freezes skin like you would not believe.

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.

Oil leaking from rear valve cover gasket & getting burnt oil smell thru air vents inside vehicle


Thi depends on whether you want to do it yourself or not. It's an easy fix, just get the gasket and remove the valve cover. It's tidious but doable. Otherwise, get ready to spend $150-200 for a shop.

I have a 2002 Nissan Altima 2.5L that is leaking oil into the spark plug tubes; can these seals be replaced or does the valve cover have to be replaced?


Yes, you need a Rocker cover (valve cover) Gasket kit. Remove the valve cover, remove all old O-rings and cover gasket, clean grooves and mating surfaces without gouging or scratching them, put the new gaskets on as per factory recommendations, tighten to the proper torque and you're done. The spark plug holes in the cover are part of the valve cover gasket kit. Any Napa, Car Quest, Pep Boys, Auto Zone will have it.

How do I replace the valve cover gaskets for a 1996 Ford Ranger w/ 3.0L Engine?


The valve covers installed on the 3.0L engine incorporate integral (built in) gaskets which should last the life of the vehicle. Replacement gaskets are available if required.
  1. Disconnect the negative battery cable. Disconnect the ignition wires from the spark plugs, but leave them attached to their wire looms.
  2. Remove the ignition wire separators from the rocker arm cover attaching bolt studs with the wires attached, then lay the wires out of the way.
  3. If the left hand cover is being removed, remove the throttle body assembly, the PCV valve and fuel injector harness stand-offs. If the right hand cover is being removed, remove the engine harness connectors, fuel injector harness stand-offs and air cleaner closure hose from the oil fill adapter.
  4. Using caution, slide a sharp thin blade knife between the cylinder head gasket surface and the valve cover gasket at the four RTV junctions. CUT ONLY THE RTV SEALER AND AVOID CUTTING THE INTEGRAL GASKET.
  5. Remove the integral gasket from the valve cover gasket channel. Note bolt/stud fasteners locations before removing gasket for correct installation. Clean gasket channel and remove any traces of RTV sealant.

To install:
  1. Align fastener holes, lay new gasket onto channel and install by hand. Install gasket to each fastener, seat fastener against cover and at the same time roll gasket around fastener collar. If installed correctly all fasteners will be secured by gasket and not fall out.
  2. Install valve cover to the engine, lightly oil all bolts and stud threads. Apply a bead of RTV sealant at the cylinder head to intake manifold rail step (two places per rail).
  3. Place the valve cover on the cylinder head and install attaching bolts and studs. Tighten the attaching bolts to specifications.

  1. Install all remaining components in reverse order of removal procedure. Connect the ignition wires to the spark plugs and reconnect the negative battery cable. Start the engine and run to normal operating temperature, then check for oil and vacuum leaks.

Is it difficult to replace all the oil gaskets? I have a leak and it seems to be getting worse.


Im assuming you mean the oil pan gasket? Oil pan gaskets are very time consuming to change on most vehicles, expecially front wheel drive because of the space. First crawl under and locate the oil pan (don't confuse with the bottom of the transmission lol). On my front wheel drive vehicle, I had to disconnect the AC lines to get to it (what a headache that was). Getting access to the oil pan is the hardest part but once you have access, the process is realitively easy. Drain the oil first or you will be taking a bath. remove the screws, clean the area the gasket is going to be touching, replace gasket and re torque the bolts to mfg. specs in sequential order as to not bind or pinch the gasket. Also, is it leaking from the valve cover? Valve cover gaskets are much easier to replace than oil pan gaskets.

Valve covers gasket leak oil


To replace the valve cover gaskets on a Sienna: The front one is easy. The difficult one is the other side, closest to the firewall. You will need to purchase a new intake plenum gasket, when you buy the new valve cover gaskets, because you MUST remove the intake plenum to remove the rear valve cover. You can NOT get the back side valve cover off of the engine without removing the plenum. Trust me.
Hope this helps, and thanks for choosing FixYa.

Use a film of gasket sealant on both sides of the new gasket when you replace it. When installing the cover, make sure there isn't any wiring or anything that could get caught under it.
