SOURCE: piston ring installation on 96 geo 1.3 liter 4 cyl engine.

If you are that deep into things you will do poorly without a good manual. Are the pistons new or used?If they are used you need to completly clean the ring grooves in the pistons or the new rings will stick and gall.Did you remove the ridge at the top of the cylinders? If not there is a good the top ring will either break or bust the upper land off of the piston. Hopefully you had a machine shop go through the block. Check the ring manufacture's web site. I am sure they will have tips and instructions.

SOURCE: what is the piston ring gap clearance for the ford

Which Piston Ring Gap? First of all you need to purchase a Hayne's Manual for your car. It will give you the specifications under the Engine section of the book. The piston has three rings on it. From the top you have your first compression ring, then your second compression ring (these "clearance" specifications or "gap"), should be the same as measured on the piston insofar as the clearance between the "lands and grooves" or between the ring and the piston groove. The third ring is your oil control ring which will have a different clearance between (for example), the top of the ring installed and the piston's groove. Then lastly, you need to place the compression rings and place them in the bore of the cylinder WITHOUT being installed on the piston. A measurement is then taken between the opening gap of the ring while in the block. To make sure it's lined up properly, invert a non-ringed piston down into the bore from the top to make sure the ring is installed at the same depth all the way around.

If you don't want to buy the Hayne's Manual, just stop by your local Dealership and get the Specifications for the two compression rings, the oil ring and the "installed" clearance or gap on the rings.

Hope this Helps,

SOURCE: what is the piston ring

The end gap is derived from the bore size. For the 2.91" (74mm) Geo 3 cyl bore, the top ring end gap is .004" divided by bore, so that is 2.91" / .004 = .012". The second ring and oil ring should be bore divided by .005", so that is 2.91" / .005 = .015". Don't file the springy part of the oil ring, as it is designed to compress and fit snuggly; just file the top and bottom ring that sandwich the springy part.

Ring end gaps for B&S 31P777 engine


If the engine the figures are required for is a re-ring using the original pistons it is important to check the amount of wear of the bore and of the piston groove clearance.

Once the ring gap is set to the minimum at an unworn part of the cylinder bore the gap should be rechecked at the most worn part and if the gap exceeds the maximum it indicates an excessively worn cylinder bore.
While this is not immediately detrimental it does mean the piston ring grooves will wear much more quickly and the job will have a shorter life and in some cases a high oil consumption can be worsened.

The piston ring groove clearance - side clearance between the ring and the piston should be 0.0015 inch maximum. It can be expected the top groove could be considerably worn and in that case new pistons would be beneficial or a Cord ring set.

May you give me a diagram to show me how to place the rings proparely on a piston


As per diagram, make sure that compression ring gaps are 180 degrees/opposite each other, also do not put gaps on thrust faces or above/inline with piston rod pin ...

Make sure you have enough ring gap as well, you need 3-4 though per every inch of bore, do this by placing ring into bore, push down about 1 1/2" with piston and check gap with a feeler gauge, if gap is insufficient you will need to file rings ....

Anyone can help me answer this how to measure ring gap!


The ring should be placed down in the cylinder bore squarely(use an inverted piston with only the bottom ring installed to get it even).Measure the gap in the ring with a set of feeler gauges.(an assembly manual should list the spec).It is important the gap is correct-too tight will cause the piston to seize in the bore when it reaches operating temperature.Too loose,and you will have excessive compression loss and oil consumption.A manual ring grinder is fairly inexpensive(if you can fabricate your own like I did,it is even cheaper).

Wats d gap in rings and n how many kms does the engine has to run


A general rule of thumb for ring gap is .003 " per 1" of bore. Example 4" bore minimum gap at bottom of cylinder for the ring is .012". IF fitting new rings then push the ring to the bottom of the bore ( smallest dia.) and measure the gap . nothing under .010". Max ring gap at this point should not exceed m.025" and if the gap exceeds this then the sides of the rings will have sharp edges from wearing on the piston lands.. The distance travelled depends on the service interval and the air cleaner being used as a dusted motor will need new rings within 15.000miles. and a well serviced motor can exceed 150.000miles before the rings need replacing

BLOW BY 89 TOPAZ COMRESSION WITHIN SPECS PCV VALVE IOK


Hello, You can still have Ring issues with good compression. The pistons have different types of rings on them to do different jobs. The top rings are your power rings, the bottom rings are your oil rings.

The oil rings prevent the block pressure and oil slop from being drawn up into the cylinder. The piston creates a siphon action and the oil rings prevent the oil from climbing the cylinder walls. All it takes is for the rings to rotate around the piston and have the ring ends line up.

That is why you offset the rings on installation from 90 to 120 degrees. It staggers the gaps of the rings for a better seal. Now you can get oil vapor if the compression rings line up to allow compression into the crankcase through the gaps on the piston rings.

Sometimes the valve stem seals can leak and allow exhaust into the upper block if you have valves that are not seating correctly.

I'm fixing my engine with new rings but rings have not fitted and yet the block has not expanded, the spare parts show the same engine no. what can i do. I'm so desperate?


your replacing the piston rings? are you using a spring compressor? when you compress the rings and set the piston down in there sleeves make sure to oil the cylinders the with the rings compressed and staggered gently tap the top of the piston with the wooden handle of a hammer. when i say stagger i mean the gaps in each ring are in a different position so as not to create a bypass of pressure or oil. if you use the compressor the piston should slide into the sleeve of the cylinder
