What are roller lifters?
Roller lifters feature a wheel supported by needle bearings and an axle. 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.
Why are my lifters making noise?
A ticking lifter is usually an indication there is a problem with your oil, especially as your car ages. It’s possible the lifters themselves are simply worn. Dirt and sludge from the oil may form in and around the lifters or along the valve train. This can make it difficult for the lifters to function properly.
Can noisy lifters cause damage?
If the problem with the noise persists and is not solved as quickly as possible, the cause of the engine lifter noise – whichever it is – can prevent other parts of your engine of working properly. It can even cause very serious problems and damages to your car in the long run.
What is a flat tappet lifter?
Flat tappet lifters are actually not flat. They have a slight crown on the face of the lifter. The cam lobe is machined with a slight taper, which causes the lifter to ride the taper allowing the lifter to spin as it rides the lobe.
What are hydraulic roller lifters?
As the cam turns the roller actually rolls along the lobe for less friction and keeps a zero lash by maintaining hydraulic pressure inside the lifter. This greatly reduces friction so it can produce more power. This reduction in friction also means no need for additional oil additives.
Are Morel roller lifters good?
My conclusion on the Morel Lifters is that they are a Good Quality Lifter at a Good price, but they don’t like a lot of lash, and are a bit noisy until they are warmed up and then they get quiet LOL. Don’t hesitate to try a set if you need some, but I wouldn’t go over 1/4 turn past 0 unless u have a reason to.
