Where I am can't find parts for ford fusion 03 l need valve stem seals can you help ?

Burning ... or leaking? It is smoking? If so, check the PCV valve, it's vacuum connections, and the integrity of the hose(s) connected throughout that vacuum system. Of course, you could have bad valve stem seals, or even bad valve guides, or even bad or broken rings. Check the front and rear main seals in the engine too.

Usually one of 2 causes. Most common is a bad valve stem oil seal allowing the oil past the valve stem when the engine is shut off.Second is a broken or bad oil ring on that piston. Be blessed.

-On top part or Inside...?
-If on top. Valve cover gasket might be lose.
-If inside or at the end that go into the engine. Piston ring has too much clearance and or valve stem seals are worn out.

I can tell you some things about this and what you decide to do about it is up to you.

Here is what can happen. The valve depends on the valve spring to close the valve. If there is a leaking oil stem seal, the oil can try to run into the cylinder. As it does this, the valve starts sticking as the valve stem gunks up. The valve spring can also be weak or broken and fail to close the valve.

You can change the valve spring and the oil seal on the stem on some motors by placing the cam where the valve is closed. Then using an adapter, force air into the problem cylinder(at the sparkplug hole) and the air pressure will keep the valve from falling into the engine. You then use a valve spring compressor and swap the springs and replace the stem seal.

On some motors, the cam is on top and in the way. Other motors use the overhead cam to press a rocker arm with the valve offset and accessible. The pushrod was eliminated and even lifters were eliminated. You can get loaner tools at Autozone, Advance, or Oreilys.

Another option is to have your head sent out and rebuilt or go to Car-parts.com for Salvaged heads with shipment to your door and all the contact info you need to get the part.

If you remove the head you will need new head bolts as the old ones stretch. Of course a Torque wrench is highly recommended as the 4 cylinder heads were subject to bad head gaskets.

You should take out the number 1 plug and look at how it is burning. You may have a water leak causing the valve to fail. The clicking noise can be the valve failing to return to its base. Hydraulic lifters can collapse too. But your noise is the extra space in the valve train causd by a sticking valve, bad lifter, or broken spring.

There are some Paperback books with pictures to do this job. You can see if you fell comfortable about trying to fix it yourself.

Hi

it sounds like it is burning oil not petrol but you will smell petrol as the oil is leaking in through the head, the valve stem oil seals will most likely have gone, very common on fords. they are very cheap bt unfortunately you have to remove the cylinder head to replace them so that means a head gasket and a new cambelt and head bolts thats where it gets expensive. in the UK you are looking at about £300 to £500 in a general garage.

there is another solution that will last for months if not years, get some STP the type that you need to heat up to get it to come out of the can, this will seal up the leaking stems and shuld stop the smoke, most people do this before they sell that car.

Valve stem oil seals often go because the car has been driven hard, but you should still expect them to go at around 80-100k miles anyway.

Hope this helps

Blue smoke = oil is burned. You have an oil seal that is worn out so yes, the valve stem seals might be the ones. Replace them and check again.

Could have been caused by bad valve stem seals on those 2 valves, they harden as they age and don't seal as well and fail.

blue smoke is oil possible worn or damaged component in head-usual problem is valve seal or worn valve guides -pull and inspect the spark plugs look for which one[s] is fouled or oil soaked that will narrow down where ur problem is

do you have an air compressor, valve spring compression tool, etc. if not get it done
