Why does an overhead cam engine make a clicking noise?
In an overhead cam engine, the camshaft lobes themselves depresses the valve while in single cam engines, the cam actuates push rods that open the valves by moving a lever called the rocker arm. Since your valves move very quickly and only move a short distance, the distance from the cam or pushrod to the valve needs to be very precise.
Why is the crankshaft noise so loud under heavy load?
This noise is loudest when the engine is under heavy load. Excessive crankshaft end play is indicated by an intermittent rap or knock sharper than a worn main bearing. The following are causes of main bearing noise: A damaged or worn connecting rod bearing will produce knock under all speeds.
Why does my car make a knocking noise?
Either, try cleaning off the carbon deposits, or replace the (EGR) valve if it is defective. Your engine has a knock sensor that detects this noise and tells the computer to retard the ignition timing. Engine spark knock may occur when the engine is working hard under load causing the (PCM) to retard timing.
When does a loose camshaft make the loudest noise?
Loose or improperly seated camshaft timing gears are usually loudest when warm. They are speed sensitive only. They are not load sensitive. Cam gear noise will usually be evident at a warm idle in neutral and sounds much like a loose timing chain noise.
In an overhead cam engine, the camshaft lobes themselves depresses the valve while in single cam engines, the cam actuates push rods that open the valves by moving a lever called the rocker arm.

Why does my car make a clicking noise when I idle?
Your fuel injectors are small electrical valves that open and close very quickly allowing a certain amount of fuel to be injected with the air your engine is drawing in.

What are the disadvantages of an overhead camshaft engine?
During engine repairs which require the removal of the cylinder head, a disadvantage of OHC engines is that the camshaft timing needs to be reset if the cylinder head is removed. In 1920-1940 Morris and Wolseley cars with OHC engines, oil leaks in the lubrication systems were also an issue.
How can you tell if you have bad lobe on your camshaft?
First, because there’s no reason not to, and it’s probably easier to access the top of the cam lobes than the valves. Secondly, because engines with VTEC-comparable systems won’t show a flat secondary lobe at the valve when you’re turning the engine over by hand.
Is there a Honda cbx250r with double overhead cams?
1938 Royal Enfield 250, CF Moto 250 V5, Honda’s XL250, CBR250, VT250F2, FT500 plus a few others. Go to CMSnl.com and look for the model, then click on the part and it will show you the part number. Seems the cam shafts were a bit of a problem on this model.
What’s the difference between SOHC and single overhead camshaft?
Single overhead camshaft ( SOHC) is a design in which one camshaft is placed within the cylinder head. In an inline engine, this means there is one camshaft in the head, whilst in an engine with more than one cylinder head, such as a V engine or a horizontally-opposed engine (boxer;
Why is my car making a clicking noise when starting?

What are the different types of cranking problems?
In a cranking system, you can divide your symptoms into one of three possible troubleshooting categories: Slow Crank: The starter will crank, however, the engine RPM is slow to start the vehicle.

Why is my car cranking but no click?
This is an important step and is often the cause of a slow cranking complaint. Yet, voltage drop also is a leading cause of click or no-click complaints because almost every vehicle manufacturer uses the heavy positive post, located on the starter solenoid, as a place to pick up the current used to supply the control circuit.
What’s the difference between no click and no crank?
Click No-Crank: The solenoid clicks but the starter doesn’t crank. No-Click No-Crank: The solenoid doesn’t click and the starter doesn’t crank. Once you’ve identified which problem you’re dealing with, then you can start to remedy it.
