How to Fix a Gasket Leak
Almost every car blows a gasket at some point. Usually, a blown gasket means hundreds of dollars in repair costs (if you’re lucky). Fortunately, there is an easier and more affordable way to fix your gasket. And, it’s so easy that anybody can do it – regardless of their level of mechanical knowledge. Today, we’re going to walk you through how to fix a gasket leak using a rubber spray sealer.
But first, let us tell you why preventing a gasket leak is so important. Over time, the metal on this gasket can corrode, and leaking fluid can cause serious problems in all other areas of your vehicle. When this metal corrodes enough, the gasket head will blow, which can often result in thousands of dollars of repairs at the mechanic.
For your safety, and the safety of your vehicle, it’s best to stop a gasket leak as soon as possible. Here are the step by step ways to do just that.
Supplies needed to fix a gasket leak
- A rubber spray sealer (Flex Seal works best here)
- A stiff-bristled brush or an old rag
- Engine degreaser or similar cleaning solution
Take off the valve cover gasket and clean the gunk off of it using a drop cloth. Over time, a valve cover gasket can accumulate a lot of debris, and this can cause serious harm to your engine. Use your engine degreaser or another cleaning solution for this step, but be sure to dispose of all waste properly.
When cleaning, put a particular focus on the groove around the outside of the valve cover gasket. There may be a strip of rubber in that groove, and you should take it out in order to clean it properly. This is also where a stiff-bristled brush (like an old tooth brush) could come in handy, as it will get right into the groove and clean out all of the oil and sludge inside.
Take a look at the strip of rubber from your valve cover gasket. Does it look damaged? Does it show visible signs of wear and tear? Or is it in fairly good condition? Depending on your answer to those questions, you’ll need to use your rubber spray sealer in different ways.
If, for example, the rubber strip is severely damaged, then you may want to avoid using it entirely, and simply spray your rubber sealer into the groove on the valve cover gasket. Or, if some parts of it are usable, you may want to take a hybrid approach: place the strip of rubber into that groove, and then coat some damaged parts with rubber sealer in order to form an effective and powerful seal.
Spray some rubber sealer around the O-Rings (or rub it on with your fingers). The O-Rings are the circles of rubber that go around those holes on the outside of your valve cover gasket. Once that is completed, re-attach these O-Rings and firmly press down. This will make the seal as airtight as possible.
After that has been completed, you can replace the valve cover gasket and wait for the entire system to dry. Congratulations! You’ve successfully fixed your gasket leak and saved a ton of money in the process.
