I have spent some time tracking oil/fuel leaks.

Ones I have found:

- Flange where oil supply to turbo attaches - someone had used "form-a-gasket or some such stuff - Made a gasket from gasket paper and leak has gone.

- Valve cover - Rubber seal was replaced at last valve change - Just had to torque hold-down nuts a bit and leak has stopped (near back of engine)

- Injector leaks - Have new hoses. Get drips of clean fluid on garage floor.Seems to leak from middle of injector. I had this once before after rebuilt injectors were installed - I think there must be a joint in the injector bidy that is sealed with an o-ring - no solution other than to replace injectors?

- Lower connection to oil cooler leaks slightly - Have not tried to fix - likely need new o-ring or seal?
