Crankshaft seals are generally made of rubber with a metal insert. This rubber fits tightly against the crankshaft whilst still allowing it to rotate.

It is a relatively simple and cheap component, but a vital one to prevent oil leaks.

Typical symptoms that require a front crankshaft oil seal to be replaced.

It is often difficult to see the actual component as it is located behind the crankshaft pulley. However, you may spot some of the following

• The crankshaft pulley is damp with oil
• Oil has been sprayed around the front of the engine and engine bay
• Oil stain under the car (if no undertray fitted)
• Increased oil consumption

FAQ’s

Can I supply my own parts?

No, we will not fit customer supplied parts unless they are a brand new item, purchased from a dealership with the receipt as proof of purchase. There is no flexibility over this due to insurance and warranty issues.

What happens if the mechanic finds that the front crankshaft oil seal doesn’t require changing and the problem is due to another issue?

In this scenario, the mechanic will provide a no obligation quote for the correct repair. Should you accept this, the mechanic can alter the booking accordingly. If you decide not to go ahead with the alternative repair, the mechanic can change the booking to a call out and diagnostic booking and charge according to the time spent with the vehicle and call out.
