What causes a rod to be thrown in an engine?

Valve Failure A broken intake or exhaust valve may drop into the piston cylinder. If the engine continues to run, the loose valve wreaks mechanical havoc in the cylinder, pulverizing the head of the piston and resulting in a thrown rod from breakage at the wrist pin.

Can an engine with a thrown rod be fixed?

A thrown rod means a portion of the rod is being thrown around inside the engine. As you run the engine, it will continue to cause more destruction. In almost every case, if you’ve thrown a rod, complete engine replacement (at a minimum, most likely a shortblock) is needed to fix your issues.

What happens when a rod goes through the engine block?

If the rod breaks while the piston is coming down, the broken rod can pierce a hole right through the engine block (like a compound bone fracture breaking through the skin). Either way, the engine is instantly ruined, and you’ll have to “blow a wad” to get the car back on the road.

Will a car start after throwing a rod?

No you can’t! What that means is that one of the connecting rods to a piston is broken and that means its time to rebuild the motor which can get expensive and is the motor worth rebuilding if there isn’t too much damage.

Can too much oil cause you to throw a rod?

In a word, yes. There are several things that might happen if a significant amount of excess oil is added to your engine. Changes in the oil pressure and overall lubrication of the engine can lead to: Engine damage such as bent rods in the engine or collapsed valve pipes.

Can you drive a car with a bent rod?

If the connecting rod is slightly bent, you may be able to drive on it without too much of an issue. However, the cylinder with the bent rod will probably have lower compression than the others. If your compression numbers are within about 10\% of each other across all cylinders, your rods are probably fine.

Can you drive a car with blown Rod?

A thrown rod causes catastrophic failure, in nearly all cases the engine stops functioning or is severely out of balance so you will not be able to drive on a thrown rod. Speaking from personal experience, once this happens your engine will stop running, period.
