You didn't specify the # of cylinders or the make/model. Piston rings are replaceable, BUT without knowing how they were tested I'm speculating, They all should be around 90-100 psi. (Pounds per square inch) The only thing I would add, this is supposing the head gasket and valves are okay. Even with that the pressure in all the cylinders should all be within 20 psi of each other. A dealer would scare me. They may want to rebuid or replace the engine. Being a 2011, unless it has high mileage and no other problems, this can be caused by a bad oil pump. If you or someone you know can think of a garage that has rebuilt engines, see what they say. With the right knowledge and the right testing equipment, it is more likely that you can get an idea what all can be wrong. (Piston rings that are bad usually results in a blue color exaust.)

Yes piston rings can be replaced! Why have you been given this diagnosis? Is it burning oil? Is the compression low on a particular cylinder......loss of power?

SOURCE: How do you know if a piston ring has gone on a Ford Puma?

Inspecting the piston rings requires that the engine be removed from the vehicle and disassembled. I don't know if this was done, but if it was, it sure was done quickly. Hope this helps and good luck.

SOURCE: my hyundai accent piston rings need a change how

If it needs rings, it probably needs a lot of other engine work, like a cylinder hone, or if it's out of spec, a bore, which means new pistons and on. You might look into a good remanufactured engine that comes with a warrantee if your has a ton of miles on it.

SOURCE: The engine has blown. I need to replace it or

It can be time consuming and the end result may not be desirable if you haven't done it before.
--- The following is just a sample of what to do once the engine is torn down: Pistons and Connecting Rods

  1. Before installing the piston/connecting rod assembly, oil the pistons, piston rings and the cylinder walls with light engine oil. Install connecting rod bolt protectors or rubber hose onto the connecting rod bolts/studs. Also perform the following:
    1. Select the proper ring set for the size cylinder bore.
    2. Position the ring in the bore in which it is going to be used.
    3. Push the ring down into the bore area where normal ring wear is not encountered.
    4. Use the head of the piston to position the ring in the bore so that the ring is square with the cylinder wall. Use caution to avoid damage to the ring or cylinder bore.
    5. Measure the gap between the ends of the ring with a feeler gauge. Ring gap in a worn cylinder is normally greater than specification. If the ring gap is greater than the specified limits, try an oversize ring set. Fig. 5: Checking the piston ring-to-ring groove side clearance using the ring and a feeler gauge tccs3923.gif

    6. Check the ring side clearance of the compression rings with a feeler gauge inserted between the ring and its lower land according to specification. The gauge should slide freely around the entire ring circumference without binding. Any wear that occurs will form a step at the inner portion of the lower land. If the lower lands have high steps, the piston should be replaced. Fig. 6: The notch on the side of the bearing cap matches the tang on the bearing insert tccs3917.gif

  2. Unless new pistons are installed, be sure to install the pistons in the cylinders from which they were removed. The numbers on the connecting rod and bearing cap must be on the same side when installed in the cylinder bore. If a connecting rod is ever transposed from one engine or cylinder to another, new bearings should be fitted and the connecting rod should be numbered to correspond with the new cylinder number. The notch on the piston head goes toward the front of the engine.
  3. Install all of the rod bearing inserts into the rods and caps. Fig. 7: Most rings are marked to show which side of the ring should face up when installed to the piston tccs3222.gif

  4. Install the rings to the pistons. Install the oil control ring first, then the second compression ring and finally the top compression ring. Use a piston ring expander tool to aid in installation and to help reduce the chance of breakage. Fig. 8: Install the piston and rod assembly into the block using a ring compressor and the handle of a hammer tccs3914.gif

  5. Make sure the ring gaps are properly spaced around the circumference of the piston. Fit a piston ring compressor around the piston and slide the piston and connecting rod assembly down into the cylinder bore, pushing it in with the wooden hammer handle. Push the piston down until it is only slightly below the top of the cylinder bore. Guide the connecting rod onto the crankshaft bearing journal carefully, to avoid damaging the crankshaft.
  6. Check the bearing clearance of all the rod bearings, fitting them to the crankshaft bearing journals. Follow the procedure in the crankshaft installation above.
  7. After the bearings have been fitted, apply a light coating of assembly oil to the journals and bearings.
  8. Turn the crankshaft until the appropriate bearing journal is at the bottom of its stroke, then push the piston assembly all the way down until the connecting rod bearing seats on the crankshaft journal. Be careful not to allow the bearing cap screws to strike the crankshaft bearing journals and damage them.
  9. After the piston and connecting rod assemblies have been installed, check the connecting rod side clearance on each crankshaft journal.
  10. Prime and install the oil pump and the oil pump intake tube.
  11. Install the auxiliary/balance shaft(s)/assembly(ies).
OHV Engines CAMSHAFT, LIFTERS AND TIMING ASSEMBLY
  1. Install the camshaft.
  2. Install the lifters/followers into their bores.
  3. Install the timing gears/chain assembly.
CYLINDER HEAD(S)
  1. Install the cylinder head(s) using new gaskets.
  2. Assemble the rest of the valve train (pushrods and rocker arms and/or shafts).
OHC Engines CYLINDER HEAD(S)
  1. Install the cylinder head(s) using new gaskets.
  2. Install the timing sprockets/gears and the belt/chain assemblies.
Engine Covers and Components Install the timing cover(s) and oil pan. Refer to your notes and drawings made prior to disassembly and install all of the components that were removed. Install the engine into the vehicle. Engine Start-up and Break-in STARTING THE ENGINE Now that the engine is installed and every wire and hose is properly connected, go back and double check that all coolant and vacuum hoses are connected. Check that your oil drain plug is installed and properly tightened. If not already done, install a new oil filter onto the engine. Fill the crankcase with the proper amount and grade of engine oil. Fill the cooling system with a 50/50 mixture of coolant/water.
  1. Connect the vehicle battery.
  2. Start the engine. Keep your eye on your oil pressure indicator; if it does not indicate oil pressure within 10 seconds of starting, turn the vehicle OFF. WARNING
    Damage to the engine can result if it is allowed to run with no oil pressure. Check the engine oil level to make sure that it is full. Check for any leaks and if found, repair the leaks before continuing. If there is still no indication of oil pressure, you may need to prime the system.
  3. Confirm that there are no fluid leaks (oil or other).
  4. Allow the engine to reach normal operating temperature (the upper radiator hose will be hot to the touch).
  5. At this point any necessary checks or adjustments can be performed, such as ignition timing.
  6. Install any remaining components or body panels which were removed. prev.gif next.gif

How to change piston rings and bearinga of n42 318i bmw engine


Ur gonna need to split the engine m8 so u have good access to the block. U then want to remove an clean the old rings an bore out with some cleaning fluid or drop of petrol. Then comes awkward part of replacing pistons with said new rings which will b tight. A good way I found was to run a fairly decent sized but slim cable tie through the exhaust port an down an out the bottom of the head. Its then a simple case of easing the new ring back into position an with a gentle but firm push. Slide the piston back into the bore. The cable tie compresses the piston rings an allows the piston to slide into place with the rings perfectly seated. Its then a simple case of remove cable tie an bolt it all back together an jobs a good un m8. Its a trick often used by petrol an nitro rc car users, but the principle is exactly the same an its a pretty much fool proof method of making sure the rings r properly seated in place. Just remember to take cable tie out wen u dun tho lol. Hope that helps mate. If u get stuck just google how to reseat piston rings using the cable tie technique. It may help if u search for the rc car version as its more in detail an exactly the same principle ok matey

Once engine has started smoke coming out


Smoke coming from exhaust is sign of a few things wrong. Either the petrol -air mix is not correct and rich fuel mix is going in. Worse oil seal leak. This means engine oil from sump is finding its way into engine cylinders and igniting with petrol. A sign that engine could be damaged soon. This needs to be addressed quickly - piston rings may be loose also.

Without knowing vehicle make or model it is hard to suggest anything further.

Black smoking on engine


is it a diesel if so your either getting to much fuel into the pistons in which case it needs a tune up for the air and fuel mixture or its getting oil into the pistons from a leaking valve oil seal or the oil piston rings are gone with this though the smoke will be a blue ish colour hope this helps ivan thats if its a diesel but very similar for petrols as well

Do you mean the whole job or just putting the rings on the piston that has been removed and cleaned?? If you mean the whole job then you need a service manual. Also the parts store can show you how to install the rings on the pistons.

I have yellow check engine light on in my 2008 kia rio and just took it to autozone and they ran a scan on it said misfire cylinder 1whats that mean and how can i fix it ?


I had the same problem with the engine misfire on my 2006 Kia Rio, I took it to 5 garages, I took it to Kia, they were all ****, and had no answer to the misfiring of my engine, yes the "engine light" came on all the time, and sometimes the engine light stayed on.

They all tried flushing the fuel injectors, well that didn't work, and they were confused why it didn't work and said that they couldn't fix it, some said it was a piston, and you might have to overhaul the engine, after that and lots of money spent I had the same problem and thought to myself,well that was one ******** theory, they were so bemused by the whole misfiring of this engine and said they couldn't fix it.

They ran lots of computer tests on my car with a misfiring code that showed up, but a code is just a code with no step by step instructions to fix the problem, no one couldn't fix the misfiring problem.

$1500 later I was about to give up until my sister said that she had found a descent mechanic, told him about my problem and told me to bring my car in.

Well to my amazement, he found the problem, the misfire was caused by the coil that had been shortening (an electrical shortening), and there was evidence of a burn mark on the coil, well he changed the whole coil and changed the spark plug leads and now the car doesn't misfire and works great - I hope this is a solution to your misfiring problem, I thought I would share my story about my Kia Rio misfiring problem - Have a great day everyone.

My timing belt broke in my dodge stratus mechanic says engine is totalled is it ?


The engine is considered a high tolerance engine and most likely the engine is gone. This means that there is no room for the valves and pistons to be in the piston chamber at the same time, As the piston goes up, the valve's need to be in the close position or there's going to be contact and with the timing belt gone. The pistons will be hitting the valves. Replacement of pistons and valves, at this point you might as well rebuilt the whole engine. Sorry for the bad news friend.

Squeaky belt and battery light on now


+++ been told to fix blue smoke...piston rings gone .

Piston rings, valve seals are a good guess for cause of blue smoke. Engin oil additives for high-mileage engines can help the blue smoke problem... Pep Boys and the like -- many different products -- just make sure it's for stopping smoke, not cleaning engines...

+++ squealin....fan belt gone.

Has the alternator belt been tightened? If not, this could be causing both symptoms: dead battery & squealing

+++ battery light on...alternator gone.

Again, this could just be a loose belt, and most likely is the problem...

How do you know if a piston ring has gone on a Ford Puma?


You cannot see a broken piston ring without taking the engine apart. If there is a broken piston ring you may or may not hear or see any evidence of it. If the piston itself is broken you will hear, see and maybe smell it with burning oil.
