It shows low oil pressure light on but oil level is fine. It is making a ticking, not like a rod knocking but like the rocker arm. Is this right?

Hello,

If you are hearing a ticking noise from the top of your vehicle's engine it is probably a stuck hydraulic lifter. Hydraulic lifters are used in your vehicle's engine to lift the roller rockers back up when the camshaft lobe passes over the valve. They are pumped up by engine oil. Just because your vehicle's oil level is where it should be doesn't mean it's getting circulated through it. You could have an issue with the oil pump or the pickup tube. I have included in the diagrams down below the instructions for the removal and installation of the oil pump and pickup tube. Please get back to us with how everything turns out.

Thanks,
Alex
