noisie lifter or lifters

First, make sure your oil level is correct. What kind of oil and oil filter are you using? Zee

First check the engine oil level! After that your engine has hydraulic lifters that automatically adjust the intake and exhaust valve clearance using engine oil pressure when the engine is running. Engines with hydraulic lifters need to have oil changes at the recommended intervals to keep the oil clean and fresh and the correct weight or viscosity of engine oil . A small bit of dirt or sludge can "gum" up the lifters and cause the oil not to properly adjust valve clearances. Sometimes this noise goes away after initial start up or after the engine warms up. If it is as simple as "lifter noise" try adding an oil additive called Risolene, it is a low viscosity high detergentcy oil additive that helps clean lifters.

Are you by chance parking on a incline or decline? I've always heard that if your driveway is slanted it causes all of your fluids including your oil to flow to one side, and when the vehichle is started it doesn't have access to the oil that it normally has.
