FAQ
Do hydraulic roller lifters need to be adjusted?
No, hydraulic roller lifters do not require periodic adjustments like solid lifters. Hydraulic roller lifters have internal valving that automatically compensates for changes in valve train clearances, allowing for self-adjustment. This design eliminates the need for regular adjustments, making hydraulic roller lifters a convenient choice for enthusiasts who prefer minimal maintenance and ease of use in their Chevy engines, especially when using lifter sets like Howards 91160.
How do I know if my hydraulic roller lifter is bad?
Signs of a bad hydraulic roller lifter include unusual engine noises, such as ticking or tapping, reduced performance, or misfires. Visual inspection for damage or abnormal wear can also indicate lifter issues. If you suspect a problem with your hydraulic roller lifters, it is recommended to perform a thorough inspection and, if necessary, replace the lifters with a reliable lifter set like Howards 91160 to ensure optimal performance in your Chevy engine.
