Well, any lateral movement of the connecting rod with the piston is not acceptable because it could wear to the point of being thrown apart over time.

Also, pins can be pressed out, I believe, even though I have never done this.

I have overhauled a 1979 Honda Accord and took the pistons out, but the machine shop said that they were ok, at the time.

SOURCE: threre is a knock in the motor and it ia not arod

DON'T LAUGH, BUT FIND A RUBBER HOSE ABOUT 5 FEET LONG CUT BOTH ENDS SMOOTH ANY SIZE WILL DO START THE CAR STICK THE HOSE TO YOU LEFT OR RIGHT EAR AND POINT YOUR OTHER EAR AWAY FROM THE ENGINE AND TOUCH THE OTHER END OF THE HOSE TO DIFFERENT PARTS OF THE ENGINE AS YOU GET CLOSER TO THE KNOCK THE SOUND WILL GET LOUDER THRU THE HOSE AND YOU CAN PIN POINT WHERE THE SOUND IS THE LOUDEST. I'VE DONE THIS MANY TIMES AND FOR MANY YEARS I HAVE A 200 DOLLAR STETHESCOPE FOR THIS AND THE HOSE STILL WORKS BETTER. ALSOWHEN YOU PUT THE CAR IN DRIVE DOES THE NOISE GET QUIETER IF IT DOES I WOULD SUSPECT A WRIST PIN IT'S REALY HARD TO TELL WITH OUT HEARING IT MY SELF, COULD BE A TIMMING CHAIN
GOOD LUCK

How doi replacing o rings on my 97 s10 2.2 motor


Remove the cylinder head. Then remove oil pan. Unbolts rods one at a time and pull piston out the top. Hone cylinder install new ting on piston and reinstall. (Make sure rod cap goes back on same rod and same direction don't for get to torque the bolts on the rod cap)

Making knocking sound


A KNOCKING SOUND IN THE ENGINE IS MOST LIKELY CAUSED BY ONE OF THE FOLLOWING
1. PISTON SLAP: Makes a sharp metallic noise. Idle engine and short out each cylinder plug. The noise will disappear when plug with bad piston is shorted. Noise will also disappear at acceleration. This can be caused by worn or out of round cylinder, or broken piston ring. Correct problem by re-boring cylinder and/or replacing piston.
2. VALVE NOISE: Makes clicking or rattle noise. Caused by excessive wear on valve stem or lifter, out of adjustment, or stuck valve. Correct by adjusting valve clearance, replace worn valve or lifter, regrind cam, replace valve guide and /or valve. A stuck valve can sometimes be loosened by passing oil through the carburetor while engine is running.

3. ROD BEARING KNOCK: Makes sharp metallic noise similar to a piston slap. Detection is opposite of piston slap. Rod knock is not heard at idle. Knock becomes louder as engine speed is increased. Caused by excessive rod bearing clearance. Correct by adjusting rod bearing clearance to .0015 inches by removing shims. May require re-pouring rod bearing.
4. REAR MAIN BEARING KNOCK: Makes dull knocking or thud noise. Detected at speeds between 20 and 50 MPH. Knock will normally decrease or disappear while pulling or decelerating. Noise will be detected the loudest at normal driving speed, when not pulling or decelerating. Correct by adjusting bearing clearance to .001 to .0015 inches. If knock is excessive, crank should be checked for out of roundness. May need to re-pour all main bearings to correct.
5. TIMING GEAR KNOCK: usually the most difficult to diagnose. If gear is loose or badly worn it will knock in all ranges. Run engine slightly above idle speed. Slowly open and close throttle. Knock will continue to be present, but just as engine slows down knock will become a slight rattle. Remove timing pin and reinsert into timing hole on timing gear cover. Press timing pin tightly against timing gear and accelerate slightly above idle. Knock will significantly be reduced or disappear. Correct by replacing both timing gear and crank gear as a matched set. The two gears should have a backlash clearance of .003 to .004. If more than .009 inch backlash, an oversize (.005) timing gear should be installed.
6. WRIST PIN SLAP: This can not be detected by shorting out the cylinder plugs. Rapidly accelerate and decelerate the engine speed. The engine will pass through a certain speed range when the wrist pin will rattle at about the same pitch as a valve tappet noise. This can be corrected by installing a new wrist pin bushing in the rod or new wrist pin f badly worn. Wrist pin should fit the piston and connecting rod with a tight metal to metal fit. The pin can be pushed into the piston and rod with a slight pressure of the hand. Pin to rod clearance is .0003 to .0005 inches.

Some piston dammage


Here's the scoop.
Underneath that piston is a wrist pin, and then a connecting rod, and then a bearing that goes around the crankshaft. The bearing is split into two pieces, upper and lower. Some folks have put the engine together, as you wish to do. The top of the piston is engineered to be a certain way. if there is a tiny imperfection, what might (maybe) happen is pre-ignition, if that part of the piston heats hotter than the surrounding surface, and will cause the engine to run poorly. Next, if the valve hit the piston, there might be some tiny damage to the connecting rod, the wrist pin, or mainly, the bearing on the crankshaft. Probably all you would see is the engine would throw a rod in the next 5,000 miles, or sooner.
I share your desire to save money and time on this. If you decide to button it up, please take some fine sandpaper and a good shop vacuum and try to smooth the imperfections in the top of the piston and vacuum all dust and shavings up as you work.
Be blessed.

How do u get rod end out of cylinder


you have to remove engine from vechicle .drain oil out.you have to remove cylinder heads and tilt engine around on engine stand you have to remove oil pan then remove rod bearings caps bolts remove cap.put piece rubber hose on rod studs protect crankshaft. then you tap piston using piece of wood tap piston from bottom worn it out from top of cylinder head.

KNOCK IN ENGINE, HOW TO CHECK FOR WRIST PIN OR ROD BEARING


These two problems will sound the same. Both can cause the piston to hit the head, both will make a fast double tap on the crankshaft. But the piston pin will be less evident in the lower pan or on the crankshaft. You will need a long metal rod and put it on the block in the area, put your thumb on top and press your ear to it. You can then hear, if it is louder in the lower block area or up in the head area. Hope this helps FixYa up. .

Exhuast vavle busting same one on 3 rebuilds. 3


Checked the connecting rod length and piston wrist-pin location on that cylinder? Before locking the head down put a pancake of modeling clay on the piston and rotate the crankshaft with a wrench to check actual valve clearance. On street engines I do this without the head gasket to add some "insurance". Compare what you see at #3 to one that has not damaged a valve. Also make sure your valve spring isn't going into "bind"...If it is it may be the wrong one (very unusual but I've seen ones get mixed up from different engines) How's the rod bearing on that rod? if it's worn out it can be "throwing" the piston at the valve.
Do what I said and you have to find something!
good luck!

How to replace the piston connecting rod on a 1993 chevrolet corsica 3.1L?


If you need to replace a rod, generally you have a bearing problem that requires crankshaft removal/replacement as well. If you have a bad wrist-pin on the small end of the rod or the rod bent from hydro-lock and bearings are good, you need to remove the oil pan and the cylinder head as the piston/rod assembly comes out from the top.
If you have a spun bearing or broken rod, the entire engine needs to be removed, completely torn down and all passages flushed...far easier to replace engine with a good used one.
To do either, you will need a manual to guide you through the process (far too long to write out here) Sorry I need to tell you this but that's just the way it is...better you know before even attempting to do the job.
