What is valve train noise?
Valve Train Noise. Valve and hydraulic lifter noise has a clicking sound that usually quiets down as you raise the engine RPM’s. A lifter is what opens and closes intake and exhaust valves. These noises can be caused by worn or sticking hydraulic lifters.
Do you need to adjust the valve on a Nissan Versa?
Thanks! It probably needs a valve adjustment, but these (like many Nissan motors) use shim and bucket lifters, to bring the clearance back to spec you need to order the proper thickness shim. I’ve explored doing it since my 1.8 has 325 000KM on it, has sounded like a TDI at idle for a long time.
When to run compression test on Nissan Versa?
Once I go 45MPH or more the tire road noise and wind noise drowns out the sewing machine valve noise. when I drive the engine for an hour, all I hear is valves. at this point to really find out if there’s a problem, I would need to run a compression test on all cylinders.
Are there hydraulic lifters on a Nissan Versa?
They’re not hydraulic lifters. Cams will wear the lifters down in a short time to the point that they will need it. Not only does it produce an audible noise when they’re out of adjustment but reduces power a bit since you aren’t getting full lift. They make a special tool that allows you to slip shims under the lifters. Click to expand…
