A Connecting rod is a major component inside the engine. The rod is connected to a crankshaft on one end and a pistion on the other. These components move at a very fast rate while the engine is running, and when they fail, it is only a matter of time before they "let loose" and severe engine damage occurs,hopefully not leaving someone stranded far from home. Anyway, the best option, if you feel the rest of the vehicle is mecahnically sound and you plan on keeping it for a while, would be to replace the engine with a rebuild. Jasper Engine company may have an engine ready for install, and they have a very good reputation. I have used them myself. So, I guess the question is; Does one repair a vehicle with this condition or is it better to purchase another vehicle? Engine replacement is far better than a vehicle payment and will pay off in the long run, but this would be totally up to you and the condition of the rest of the car.

2003 chrysler concord nocks pings left side


Knocking and pinging are two separate things. "Knocking" usually refers to the sound an engine makes when internal mechanical parts, such as piston rod bearings or connecting rod bearings, begin to wear and cause a deep "knock, knock, knock" sound during engine rotation. "Pinging" refers to the tapping sound you get upon acceleration, either when using fuel that is to loo octane for the vehicle, or when static timing is set too far advanced, or when the cylinder heads are overheating due to clogged water channels or thin oil.
If you are hearing KNOCKING on the left side, it is likely time for an engine rebuild. If you are hearing PINGING, you may need a better grade of fuel, or you are way overdue for either an oil change or a major tune-up.

I've changed my engine mounts 3 times on my 2004 A4 cabreolet and they fail within miles(start to vibrate & then within a week, severe knocking) the 2nd time, also changed the ****** mount, 3r


Engine mounts do not go bad in five miles. Sounds like you're treating a symptom and not the cause of a more serious issue. Are you sure all cylinders are firing correctly? That the severe knocking is not coming from your engine internals? Have you checked the steel around the engine mounting points for cracks or other damage? And just in case, if the mounts you are using are poly, are you lubing them before installation?

May be my rods but my engine makes a kind of knocking noise what could it be


Once you run the engine out of oil you damage the bearings that the engine needs to turn and operate smoothly, the bearings are called the rod and main bearings of the crankshaft. At this point the damage is done and hence the noise you hear is a result of the damage. The fix of course is to replace the engine or have it removed from the truck and crankshaft machined smooth again and all the bearings replaced, whether you opt to do this rather than just replace the whole engine with a rebuilt one depends on how many miles on the truck and how often the oil have been changed, it should have been changed every 3,000 miles, if you have not maintained the oil changes then it is a waste of money to repair this engine, just have a rebuilt one installed.

2006 mazda 6 2.3 65,000 miles. It started making a very, very loud ticking / knocking noise at all times following the rpms. The valve clearences are within spec, but that's all i've checked. ...


Mobil oil won`t cause this problem however if the mechanical parts have just succumbed to metal fatigue or defect.the noise could be rocker arms,connecting rod noise or a failed piston.its hard to say without hearing the noise as it is to try and describe the noise.

I have an unnerving repeated knocking (louder than clicks) sound coming from my engine. the mechanic changes the main engine bearings but it won't go away. it goes away at high revs but very loud at lower...


I'm assuming your mechanic changed the rod bearings also. There is also a thrust bearing which keeps the crankshaft from sliding back and forth as it spins. Also check your flywheel/flex-plate, depending on whether your vehicle is auto or stick. Sometimes they crack and can cause a knocking sound.

What will I need to replace on my 1995 prelude if a rod is knocking on my si motor?


Replacing the Rod entails tearing your whole motor down, removing the Crankshaft, replacing the Rod Bearings, Rod and Piston and it is not cost -effective to do all that labor for just one Rod. You are better off replacing the whole motor than just fixing the one part. The most cost-effective solution I found that alot of people are doing, is to find a Engine Shop in your area that sells used Japanese Engines Imported from Japan. The engines are used, but only average about 30K miles on them, because in Japan they have very strict Smog and Emission Laws and when a vehicle in Japan reaches 30K miles, they mandatory have to pull out the old motor out and replace it with a new one, which leaves thousands of perfectly good Japanese engines to use as replacements. A good used Motor runs anywhere from $400-600 dollars plus labor, unless you are Mechanically Inclined and you can do the install yourself. I replaced two Hondas and one Ford (Mazda) Festiva motor using this method and never had a problem with them ever.

Knocking noise in 3.8 lit 95 ford taurus


You can not put a liquid where metal is supposed to be. Just a general rule of thumb. The high RPM's had been too much for the engine, and A rod bearing, or rod knocking is about the same thing. Dont try the heavier oil thing, I hate when ppl suggest such stuff. Just replace the bearing, or in most cases and cost efficent, the engine.

Loud knocking noise from engine


A loud low knock? And it sounds like a disel now, sounds like one of your rod bearings is going bad. Basically, unless you want to put a new motor in it or have the one in it rebuilt, the only thing you can do is drive it till it blows. Sorry to be the one to give you bad news like this, but your motor is old. Parts are worn out. You either have to freshen it up or let it die.
