Oil Leak Diagnosis
The seriousness of an engine oil leak can range from a minor annoyance that leaves spots on the garage floor, to a serious problem that triggers the oil warning light and check engine light. When the engine oil light illuminates and/or the oil pressure gauge reads close to zero, it is best to pull over to the side of the road and shut off the engine to minimize the possibility of permanent engine damage.
When you suspect that you have an oil leak, here are a few simple steps that will help the process of locating an oil leak and will aid the shop in repairing it correctly.
1. Does the oil leak leave spots on the ground?
2. Where does the oil leave the most spots? ( use a paper towel under the car to help you )
3. Are the oil spots under neath the engine, or more to the rear like the transmission?
4. What color is the oil? Is it red, brown, yellow, clear? ( maybe it is not oil ? )
5. When does the leak seem to happen? Is it just after driving, anytime or only over night?
6. To the best of your ability, write down answers to these questions and bring them to your shop.
An Oil Leak Diagnosis can involve specialized oil dye and tracing equipment, scan tools and specialized technician training.
The purpose of this article is to provide an outline for some of the essential steps involved in performing an Oil Leak Diagnosis. This guide can be used—by you and the shop—to track the progress as the mechanics perform these inspections.
