Can you drive with a bad rocker arm?
With broken or loose rocker arms, the exhaust valves and intake valves can't function correctly and the cylinder associated with the faulty rocker arm will be disabled. This will ultimately limit the performance of your engine and your ability to drive the car smoothly and safely.
What are the signs of a bad rocker arm?
Common Symptoms of the Bad Rocker Arm:
What are rocker arms used in engine?
The rocker arm is the part responsible for transmitting the movement of the camshaft towards the intake and exhaust valves of the engine, a process that occurs through the direct contact of these parts with the tappets and according to the movement of the shaft.

How long does it take to replace a rocker arm?
How long does it take to change a rocker arm? Once all of the rocker arms are installed, the throttle cable bracket, throttle body, spark plugs and engine's air cleaner assembly will all be installed in reverse order. For the experienced mechanic, the entire job should take two to three hours.
Do DOHC engines have rocker arms?
DOHC engines lead to easier implementation of multivalve engines, as they don't require rocker arms and other supporting hardware for each valve, thus allowing for easier and more efficient breathing of the engine.
What is a tappet in an engine?
A tappet is most commonly a component in an internal combustion engine which converts the rotating motion of the camshaft into linear motion of the valves, either directly or indirectly. An earlier use of the term was for part of the valve gear in beam engines beginning in 1715.
What is the main purpose of rocker arm?
A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.
Is the rocker arm part of the engine?
A rocker arm refers to a part in your vehicle's internal combustion engine, helping it run efficiently and safely. This moving lever transfers the radial movement from the cam lobe into a linear movement that can be used to power the car.
Why are my lifters ticking?
Lifter tick can happen due to dirt in your engine oil, low engine oil levels, improper lifter spacing, or overall faulty lifters. You can get rid of the lifter ticking sound by changing the engine oil, clean the lifter with oil additives, adjust the lifter spacing, and in rare cases replace the entire lifter.
Which is better DOHC or SOHC?
A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. To sum it up, a 4 Valve per cylinder SOHC engine with a lighter valvetrain mass would have better performance characteristics at the lower end of the powerband.
How do I know if my car is DOHC or OHV?
You close the front drivers door and you walk around to the front of the car and open the hood. There in front of you lies your engine. Right on top of the engine it will typically tell you whether or not it is OHV or DOHC.
Why is a SOHC more preferred over an OHV engine?
An SOHC generally uses two valves per cylinder while a DOHC uses four valves per cylinder. “OHV” means “overhead valve” and “OHC” means “overhead camshaft” configuration of the cylinder head. The OHV is a more compact design but less efficient while the power output is higher as compared to an OHC.
What is a roller camshaft?
Roller Camshafts
This wheel is attached to the bottom of the lifter body. The lobes of roller camshafts are machined perfectly flat. Roller lifters are linked together, or anchored somehow, to prevent them from spinning. Roller Cams minimize friction. This provides more power.
