How do i chang worn rings? - Festiva Ford Cars & Trucks

Your compression rings may be worn or dirty. On next oil change use a high mileage oil with an oil additive that will clean the rings.

The 1---2 synchro ring is worn. You can cheat without buying parts by taking the 4th gear synchro ring and swap it with the 1---2 synchro ring.

The carbon suggests that oil is finding its way into that cylinder and oiling/carbonising the plug.

The mechanic changed the rings so it's doubtful that the oil is finding its way into the cylinder, past the rings. The only other thing I can think of is that the valve stem guide is worn (this would allow oil down into the cylinder) or the valve stem seal is perished/worn.

The photos below are generic images. They are NOT of your car:




A valve in the valve guide. A worn guide can allow the valve stem to 'rock' and permit oil to trickle down the valve stem into the cylinder.



The seal itself - rubberised.

There's many different types of seal. General image below just for illustration purposes:



Bluish smoke indicates that oil is being burnt in a cylinder. To be honest, worn valve guides/worn seals are quite common. You say your car is misfiring? That would indicate quite a lot of oil is fouling the plug. In most cases there would be no misfire after just 3 days. The exhaust would cough out bluish smoke at start up and maybe on the over-run, when going downhill.

A short term measure is to try a can of valve seal additive to see if the problem temporarily goes away. Repair is the best option though.



Try a can of valve seal? It's worth a shot..

Either worn valve guides, valve guide oil seals on that particular cylinder, or worn piston rings. You need to perform a compression test to find out which one of these it is.

Compression check each cylinder with all plugs removed. Take notes on which cylinder has the weakest compression.

If no compression difference and if all operating within range, then change the valve guide oil seals on problematic cylinder.

If the cylinder shows a significant drop in compression, then drop no more than five or six drops of oil down the plug hole of the problematic cylinder, and perform the compression test again. The oil will temporarily seal any worn piston rings, so the pressure should rise when retesting if the rings are worn. If the pressure remains low, then your valves are not sealing properly and require attention.

thats shows your car engine is worn out. or first change your engine oil and drive for a while like two days test, when the problem is not solved then your car Piston Rings are worn out..especial the Oil rings which passes the slite oil through the compression rings up to the combansion chamber till comes through the breather ending to the Air cleaner. but i would recomend u to change the oil first before getting deeper. all the best.

Helllo there
Symptom: Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it. Possible causes:

1. The engine's piston rings may be worn.
   The Fix: Replace piston rings. (Generally not a DIY job)
2. The engine's valve seals may be worn.
   The Fix: Replace valve seals. (Generally not a DIY job)
3. Damaged or worn valve guides.
   The Fix: Replace valve guides. (Not a DIY job)

Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.
Possible causes:

1. The PCV system is not working properly.
   The Fix: Replace PCV valve.
2. The engine may have mechanical problems.
   The Fix: Check compression to determine engine condition.
3. The engine's piston rings may be worn.
   The Fix: Replace piston rings. (Generally not a DIY job)
4. The engine's valve seals may be worn.
   The Fix: Replace valve seals. (Generally not a DIY job)

piston rings are worn. do an oil change and substitute 1 qt of oil with 1 qt of lucas oil treatment. when the engine heats up the oil thins and gets past the rings and combusts along with the fuel. the fix i recommended will only reduce the sympyoms and confirm the rings are worn. you'll need a ring job to fix.

There is a O ring it is probably worn out.You willhave to empty your system to fix the O ring.And if you decide to do this you may as well change them all at the same time.If one is worn the others may be going as well.

If you changed rings and valve gaides before you fitted new rings have you check cylinder block?it mybe cylider worn out so it was to rebore engine block and put new piston with new rings.
the ather thing it hapen sometimes when you fitting piston rings, check how piston rings is it should be all piston rings defrent direction inside the piston groves.
Use original parts.

You should try doing a tune up change spark plugs, wires, pcv,and fuel filter.it's reasonable to assume that the rings and
valves (inside the engine) have become worn. Worn rings
and valves will cause the engine to have low compression
and low compression = weak power.
You may be curious as to why the engine's lack of power is
most evident when driving up a hill. Well, when a vehicle is
going up a hill, the engine is under more stress than when
driving on a flat road. Therefore, any wear in the rings/valves
will tend to be revealed - in the form of compression - when
the engine is under stress.

you will need to have a mechanic verify that the rings and/or
valves are indeed worn. Incidentally, this generally involves
what's known as a "wet compression test".
If the mechanic tells you he positively confirmed a worn ring
and/or worn valve condition, don't immediately authorize him
to do the work. Why? Because, this type of work is very
expensive and therefore you'll want to get several opinions
before jumping into anything. By the way, even though this
vehicle's high mileage strongly points to the above diagnosis,
it's possible the cause of this problem is something else.
For example, one of the electronic sensors that controls the
engine may have gone bad. hope this help have a nice day.
