If you notice a puddle of oil forming under your Honda CR-V, it may be a sign of a worn out oil pan gasket. Changing the gasket on some Honda CR-V models is quite involved and requires removing the engine. However, 2002 and later Honda CR-V models with a 2.0-L engine is more straightforward.
Park the Honda CR-V on a level surface, set the parking brake and block the rear wheels. You'll need to crawl underneath the vehicle, so if you need more clearance, jack up the front end on a jack stand, making sure it's secure.
Disconnect the negative battery cable. Remove the front splash shield, the oxygen sensor and front exhaust pipe. If your CR-V has an automatic transaxle, remove the torque converter cover.
Place an bucket under the oil pan. Remove the oil pan drain plug carefully and let the oil drain into the bucket. Once the oil has drained, replace the plug.
Loosen the bolts holding the oil pan in place and remove them with your fingers so they won't drop in the bucket.
Scrape off the old oil pan gasket with a thin putty knife or a similar tool. Wipe the surface with solvent to be sure it's completely clean and put the new gasket in place.
Replace the oil pan gasket and tighten the bolts securely. Replace the torque converter cover, if necessary. Reattach the front exhaust pipe, oxygen sensor and front splash shield and reconnect the negative battery cable. If you jacked up the vehicle, lower it.
Pour fresh oil into the crankcase and check the level with a dipstick to be sure it's at the fill level. Pour the old oil into an empty milk carton and take it to a garage or a hazardous waste disposal facility.
