Any internal coolant leak can cause a milky residue in the valve cover. Head gasket, intake gasket, cracked/warped head, cracked intake are possible causes.
The head gasket seals the head to the engine block. Coolant and oil flow through the head. The gasket prevents then from mixing together. The valve cover gasket only prevents oil from splashing onto the engine and exposing the valve train and moving parts to the outside of the engine. No coolant makes contact with the valve cover gasket.
i need a detailed diagram on how to replace a valve cover gasket on an 2002 kia sportage. no one makes a repair guide for this vehical
Please re-write this so it makes some sense
It makes a sticky white substance that will cover the flower and the flowers that surround it.
The thermostat goes in the recess of the manifold . The gasket should be glued to the thermostat housing. Silicone sealer makes a metal surface slippery, so if used, should be done sparingly. Let the two adhere and install the housing to the intake. Do not over tighten as a bolt could possibily break. BE SURE THE SURFACE IS CLEAN of the old gasket.
Felpro makes an excellent retrofit gasket for this application. Follow the provided instructions, but also use a thin coat of High Temperature RTV on both sides of the gasket prior to assembly to maximize sealing. Valve cover and head surface must be clean and grease free, and the cover must bolted down before the RTV sets to seal properly. Replacement is a simple bolt off/on operation and shouldn't take more than 30 minutes to do.
It's a bear to get to all the bolts on the back side of the block. Remove the decorative cover on the top of the engine and the block looks pretty much like any other. Remove the valve cover, clean it and the head surface off well, replace gasket, reassemble, re-torque the cover bolts in the proper order (and I don't know what that is off the top of my head). Lots of mechanics use a better sealant than what comes in the gasket kit. I gladly pay a mechanic to bust his knuckles doing such a job. You probably want to replace the front gasket at the same time, and inspect both the heads and cams for damage. If you are replacing the gasket because it appears to be leaking, it makes some sense to suspect additional damage. SOme blow-by is expected, your engine block will not remain spotless.
air lock or head gasket Had leak in intake manifold gasket, also water pump was going out. Cost $$$ but not as much as if I'd kept driving.
A chemical reaction makes a new substance.
Oil filter installed incorrectly as in too tight, too loose, the gasket was not oiled prior to installation, or the old filter gasket was left on. It can also be a valve cover gasket leaking and running down by the filter. Replace the oil filter and oil the gasket and tighten 3/4 turn after it makes contact with the mounting surface. If the leak persists if is not the filter.
your oil and coolant mix. then you have water in your oil and it makes a white grease. Then the engine will seize if you don't do anything about it. The gaskets is like $30, To put on a intake manifold you need a torque wrench, torque spec and torque sequence. Go buy yourself a Chilton or Hayes manual for you car and read it. If it don't cover it completely, read more and apply what you know and fix the car to your capabilities. Or go spend a lot of money not to get your hands dirty
Vacuum leaks at the intake manifold gaskets, which causes the vehicle to run lean and cause the check engine light to come on. This is usually caused by a poorly designed baffle in the front valve cover that allows oil past into the PCV system ,and into the intake manifold which softens the gaskets and makes them leak. There is a redesigned valve cover to correct this. Raise the hood and see if the front valve cover is black(origional problem cover). If it has been changed to the new design valve cover, which is an unpainted aluminum cover(new design), then the intake gaskets may have already been replaced as well.
