Identifying a Cracked Oil Filter Housing

Visible Leakage and Oil Loss

A cracked oil filter housing is most noticeable when you see oil leaking or oil loss around the filter. For example, oil may pool on the ground or a garage floor.

This is a dangerous scenario because running a car without oil, even for 10 seconds can cause damage to the engine.

Remember to:

  • Check for oil dripping from the engine
  • Inspect the filter housing for cracks or damage

Oil and Coolant Mixing

In some cases, a cracked housing can cause oil and coolant to mix. This can result in damage to the engine. To identify this issue, look for:

  • Milky or frothy substance on the dipstick or oil cap
  • Unusual engine overheating

Check Engine Light and Oil Pressure

A cracked oil filter housing might trigger the check engine light or cause low oil pressure. Pay attention to:

  • Illuminated check engine light
  • Oil pressure gauge indicating low pressure

By carefully checking these aspects, you can identify a cracked oil filter housing and take the necessary steps to fix it.

Common Causes of Cracked Oil Filter Housing

Material Fatigue and Corrosion

  • Material fatigue occurs when the housing weakens over time due to constant pressure and stress.
  • Corrosion can happen due to exposure to chemicals or moisture, leading to the weakening of the housing.

For example, a plastic housing can become brittle and crack easily, especially under high temperature or pressure.

Incorrect Installation and Over-Tightening

  • Incorrect installation involves improper alignment or misuse of bolts, leading to cracks or leaks.
  • Over-tightening can cause too much stress on a filter housing, eventually leading to cracks.

A common example is when a mechanic overtightens the filter and the plastic assembly cracks, causing oil to leak.

Damaged Gaskets and O-Rings

  • Damaged gaskets and O-rings can occur when the sealing components are worn, damaged, or incorrectly installed.
  • Leaking can happen when pressure builds, forcing oil or coolant to escape through weak points.

A notable example is an oil filter installed too tightly, causing the gasket to be damaged and leading to leaks.

Steps to Fix a Cracked Oil Filter Housing

Assessing the Damage and Cost

Before you fix a cracked oil filter housing, assess the damage. Examine the housing for cracks and leaks.

If you suspect a leak, look for stained areas on the engine block and the back of the bell housing. The cost to fix the cracked housing will depend on the extent of the damage. For example:

  • Minor cracks may be repaired with sealants
  • Major damage may require housing replacement

DIY Fixing Cracked Oil Filter Housing Problems

You can try to fix the oil filter housing yourself, using the following steps:

  1. Locate the oil filter housing under the hood of your car and check for signs of leakage or damage.
  2. Drain the engine oil and coolant from your car using a drain pan and a wrench.
  3. Remove the air intake hose, the serpentine belt, and the alternator to access the oil filter housing.
  4. Disconnect the electrical connectors and hoses from the oil filter housing and remove the bolts that secure it to the engine block.
  5. Carefully lift the oil filter housing out of the engine bay and inspect it for cracks or wear.
  6. Replace the old oil filter housing with a new one and install it in reverse order of removal.
  7. Refill the engine oil and coolant and check for leaks.

Remember to take your car out for a test drive once you are finished and ensure there are no oil leakages on the road.

Choosing a Mechanic or Dealership

In some cases, it may not be possible to fix the oil filter housing yourself. In such cases, you should either go to a mechanic or your dealership to get the repair done.

Both has its pros and cons.

When selecting a service provider to fix a cracked oil filter housing, consider the following factors:
