Grease the camshaft bearings with high-pressure grease, then install the camshaft. Since the caps are sensitive to position and direction, snug the caps and then torque them onto the block from the center moving out. Rotate the crank to see if it binds up. Step 4: Install the timing cha...
Atiming beltor timing chain links the crankshaft to the camshaft so that the valves are in sync with the pistons. The camshaft is geared to turn at one-half the rate of the crankshaft. Many high-performance engines have four valves per cylinder (two for intake, two for exhaust), and thi...
You will notice in the procedure that it’s not necessary to remove the oil pump to swap the cam. However, if you will be changing the timing gears and chain, then the pump will need to be removed. There’s a trick to reinstalling the oil pump that will save time and effort. The ...
If the bearings that allow the crankshaft to turn freely are worn out, the crankshaft cannot turn so the engine cannot run. If the valves do not open and close at the right time or at all, air cannot get in and exhaust cannot get out, so the engine cannot run. If you run out of...
That’s a bit of an open-ended question as there are so many variables to take into consideration. However, “built” engines usually contain forged pistons and rods with upgraded bearings to handle more abuse. From there, the complexity increases as you get into port work, cams, etc. I ...
I had the same issue on a 2012 5.3 and in my case it was the camshaft trust plate on the front of the engine (behind the timing set) Reply ALVIN R WALTON says: May 23, 2023 at 1:44 pm sounds like you have an oil pump problem or clearanced cam bearings, working for...
and any bearings that allow things like the crankshaft andcamshaftsto rotate freely. In most cars, oil is sucked out of the oil pan by the oil pump, run through the oil filter to remove any grit, and then squirted under high pressure onto bearings and the cylinder walls. The oil then...
Excitement, rather than fear, takes over as you press the button and the green light of a descending vehicle shows up on your dashboard. You engage in first gear and accelerate just enough for the nose of yourFreelanderto tip over the ridge. Then you remove your f...
When it comes to drum brakes, theslack adjusteris a critical component that connects the brake chamber push rod to the brake camshaft. It is designed to adjust the brakes automatically as the brake shoe friction wears down. A properly adjusted slack adjuster helps ensure that your brakes respond...
The two main parts needing oil are the pistons (so they can slide easily in their cylinders) and any bearings that allow things like the crankshaft and camshafts to rotate freely. In most cars, oil is sucked out of the oil pan by the oil pump, run through the oil filter to remove ...
