Leaking oil pan? You have to know that now!

Is the oil pan leaking? We know the symptoms, we have some information about the repair and we can also give a rough estimate of the costs involved. Yes, first some general information. Combustion engines require engine oil for lubrication. Without it, the metals in the engine would rub against each other and engine failure cause. The oil pump(s) transports the engine oil through the oil circuit. It is caught in the oil pan and bolted and sealed to the engine block. If there are leaks from the oil pan, this may result in insufficient oil quantity for engine lubrication. As a result, engine damage can occur and the leaking oil also pollutes the environment. But what are the signs and should you simply continue driving with the defect?

Those are the symptoms!

• Oil stain under the car
• Oil level below minimum
• Visible leaks (or “sweating”) on the oil pan seal or the drain plug

If you suspect that the oil pan has a leak or a defect, you should never continueotherwise there is a risk of engine damage. In addition, the environment suffers greatly. Ideally, a workshop is visited as soon as possible. And how important is a damaged oil pan for the general inspection? The consequences depend on the specific defect. In the case of slight damage but a tight oil pan, the general inspection is usually still passed. The same applies to a light one Oil sweating. However, a leaking and dripping oil pan is one significant damage. In this case may no plaque be granted.

What typical damage can it do to the oil pan?

By bouncer, Accidents or an age-related one wear damage to the oil pan may occur. On top of that, it can happen that the oil drain plug was not tightened to the specified torque during the previous oil change, or that the old sealing ring was reused. These causes can also lead to permanent oil loss.

workflow

Whatever the problem, first of all, there is a Removal of the oil pan necessary. Depending on the vehicle model, there may be deviations in the process. First of all, however, the underride protection be dismantled. After that it will Engine oil drained. Usually there is already good access to the oil pan, so that the Disassembly can be carried out with ease. In individual cases, other components or, in the worst case, even the entire engine have to be removed. The effort therefore varies greatly.

At a worn oil pan gasket this is first removed, whereupon the sealing surfaces are cleaned. In the next step, the oil pan gets a new one seal. In the event of damage caused by an accident, replacement will be made with a new part. Here you should avoid used car spare parts, as these can be warped. For this reason, work on the oil pan should only be carried out in a specialist workshop, where experts with know-how and special tools work. And the waste oil must be collected according to the environmental protection guidelines and disposed of accordingly.

Cost of repairing/changing the oil pan

Depending on the vehicle model, there are different total costs. For some vehicles, the change is within one hour performed while others up to eight hours take advantage of. In individual cases, it is not possible to avoid dismantling the entire engine or the subframe, since otherwise there is no access to the oil pan. As a rule, however, you can expect a working time of one to four hours. At an hourly rate of 100 euros, costs between 100 and 400 euros are incurred. When installing just a new one Oil pan gasket are usually bare for the material costs 5 to 75 euros calculated. As a well-known manufacturer is here Elring to mention.

If the defect in the oil pan is so severe that it has to be completely replaced, the material costs are between 100 and 600 euros. Also new Engine oil as well as a new one oil filter may need to be purchased as the oil will eventually need to be drained for removal. Depending on the amount of oil and the type of oil, costs between 30 and 200 euros due. It must be mentioned here that special types of oil are of course much more expensive. So if you only have to repair a defective seal and are confronted with an easily accessible oil pan, you only pay a small contribution about 150 Euro. A completely defective oil pan, which is difficult to reach, can cost up to 1.500 euros.

What is the importance of the oil pan?

As the Reservoir for the engine oil the oil pan is bolted to the engine block and sealed. It also ensures that the oil stays cool. A VW Golf VII, for example, has a plastic pan, while a metal oil pan is used in the VW Golf IV, for example. Depending on the vehicle model, the capacity is between 2 and 8 liters. The oil drain plug on the underside allows the engine oil to be drained as part of certain repairs or for regular oil changes.

The following note is essential: For safety reasons, tuningblog recommends all repair, inspection and maintenance work exclusively to be carried out in a specialist workshop! Although our information is summarized to the best of our knowledge and belief, we cannot assume any liability for the content. All information is therefore "without guarantee".

Of course, that wasn't the end of it!

In this tuningblog category there are guides and instructions for common defects/repairs on the vehicle and for installing accessories/tuning parts. Our articles explain in a simple way common defects and the corresponding repairs, as well as explaining how the first signs of a defect become noticeable. In most cases, we also have initial clues to the repair instructions in our repair instructions approximate The costs of the pending repair are listed. The goal of our subcategory “Auto Repair Guide“ is to create a head start in knowledge for the next visit to the workshop with initial tips. This may save you from tedious troubleshooting and small things can perhaps be done directly on your own. The same applies, of course, to the installation of accessories/tuning parts. Here, too, we would like to help with the implementation with instructions and tips. There are many other posts on this as well. Below is an excerpt of the last and HERE there are all previous instructions:
