Reasons for Oil Leaks in Vans.

1 - Bad Oil Seal Van Oil Leak

Van Oil Leak can be caused by a Bad Oil Seal. Oil Seals stop oil from leaking out when an engine or car part moves. When Oil Seals go bad oil is able to escape. Oil Seals can fail due to age, dirt, dust and lack of use. Vans older than 10 years are likely to have bad Oil Seals. Vans that sit around for long periods of time can have an Oil Leak as Oil needs to move to protect the Oil Seal from going bad.

2 - Bad Gasket Van Oil Leak

Gaskets are sandwiched between parts of the engine and usually held in place by bolts applying pressure to the joining of the parts to prevent a Van Oil Leak. These gaskets can be made from special paper, rubber, cork, plastic and even metal. Over time they no longer work as well and are not able to stop oil from escaping.

3 - Pressure build up

If pressure builds up in an engine in places where it was not meant to it can push oil out. Worn out engines that allow engine gases to escape and bad PCV Valves can cause this.

4 - Bad Assembly

Bolts not tightened down correctly so not enough pressure on the gaskets to form a good seal.

5 - Van Oil Leak because of Bad Repair

Van Oil Leak can be caused by a bad repair. Maybe a seal was not replaced, gasket not cleaned off fully before new gasket added. Maybe the wrong oil was put in which attacked the seal making it no longer work.

6 - Part Removal

Hose taken off that was needed. Oil pressure sensor removed.

7 - Extreme Environment

Heat can thin out the oil making it too thin for the seals.

Cold makes oil like sludge which can increase pressure as it does not flow.

8 - Too Much Oil

Only so much oil is supposed to be put in the engine. If too much is put in then it can start to reach places that are not protected from leakage.
