How-To/DIY: Replacing Oil Pan Gasket

Over time, certain parts tend to naturally deteriorate due to outside elements and normal wear and tear. A common part that simply wears out for all cars are gaskets. A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow “less-than-perfect” mating surfaces on machine parts where they can fill irregularities. Some noticeable examples of a gasket gone bad is a vacuum leak causing idling issues or thick layer of grime buildup.

In this How-To/DIY tutorial, I will show you how to replace an oil pan gasket.

Step 1 :

  • Remove the 17mm oil plug bolt and drain the oil pan

  • Remove transmission flywheel cover

Step 6:

  • Tighten all bolts and nuts starting from bolt Number 1 clock-wise in three steps.

  • Torque: 12 N∙m (1.2 kgf∙m, 8.7 lbf∙ft)

  • NOTE: Excessive tightening can cause distortion of oil pan gasket and oil leakage.

  • You want to tighten the oil pan evenly as possible to the bottom block to avoid warpage of the gasket.
