How are cam lobes lubricated?
One end of the camshaft is sealed. The other end of the camshaft connects to an engine at a bearing oil gallery. As oil is pumped into the shaft, it is forced out of the holes and around the camshaft and the cam lobes. Because each cam lob has these oiling holes, lubrication is provided to all lobes simultaneously.
Can a cam be polished?
Camshafts can be rebuilt if they have lobe wear, as long as that wear is not excessive. You can see that the wear is not deep and just looks like the cam has been scratched. Belt polishing is the traditional method, used by engine builders for many years, to polish crankshafts as well as camshafts.
How do you clean a cam shaft?
The only thing you should use is alchohol no abrasive brushes, pads wheels, or cleaners, it will ruin your cams. Nothing with water in it, it will rust your cams. If they are rusted use wd40, rub them with wd40 soaked clothe till the rust is removed. This is the only way to take care of cams without ruining them.
How do you clean a cam?
Apply liquid dish washing detergent directly to the cam head, and then use a stiff-bristled brush to clean thoroughly all around the head, especially in the springs and inside the cam lobes. The Metolius M-16 brush is perfect for this task, but a toothbrush also works well.
Is there a way to remove sludge from an engine?
There are in fact simple sludge removal techniques that are used for routine car maintenance rather than engine sludge removal. But first you need to understand that old engine sludge can get really hard like stone and the only way to get it out completely is to take the engine apart and clean it thoroughly.
What happens when you change the camshaft lobe separation angle?
“Changing the lobe separation angle changes the amount of overlap that exists during the time the intake and exhaust valves are both open,” echoes Doug Patton of Pro Line Race Engines. “On a naturally aspirated engine, the lobe separation angle has an effect on whether the engine reaches peak torque a little earlier or later in the rpm range.
What do lifters do in a cam in block engine?
As found in a cam-in-block engine, lifters are responsible for transmitting the movement of the camshaft lobes to the pushrods. The pushrods actuate the rocker arms, which open the valves.
How can I get rid of the lifter noise?
Allow the engine to idle for 20 minutes, repeating the lifter pump-up procedure in step three about once every three minutes. Drain the oil, unscrew the old filter from the block, replace it with a new one and re-fill the engine with the recommended oil.
