Valve Cover Gasket Replacement Service & Cost

What is the Valve Cover Gasket all about?

The valve cover is a metal cover that is found on very top of the engine. The valve cover is attached to the engine by a gasket made of rubber or cork. The valve cover and gasket seal the top of the engine and prevent oil leaks. These covers are removable so the mechanic can access the valves for adjustment. Because of the high temperature of the engine, it is common for the valve cover gasket to get brittle and break. If the gasket is worn out, it will leak engine oil and the top of the engine will be covered in oil. Since the engine is losing oil, running the car for too long without an inspection and repair can cause engine damage.

Keep in mind:

When the valve cover gasket is replaced, the valve cover should be inspected as well.

How it's done:

  • Inspect the valve cover for leaks.
  • Remove and replace the valve cover gasket(s) if faulty.

Our recommendation:

If you notice oil on the ground beneath your car, get your car inspected as soon as you can. Do not drive the car for too long with low engine oil. If they see an oil leak, most mechanics will inspect the valve cover gasket first. Schedule regular oil changes to minimize the sludge formation in your engine.

What common symptoms indicate you may need to replace the Valve Cover Gasket?

  • Oil is leaking.
  • Debris and oil around the valve cover.
  • Slight oil smell.
  • Oil found in spark plug wells.

How important is this service?

Your engine’s internal pieces are lubricated with oil. This oil needs to stay in the engine, because the engine relies on it, and it can be harmful if it leaks out. To keep the oil where it belongs, your engine is sealed in many places. On the top, your engine is sealed by the valve cover. This valve cover has a gasket (which is made out of rubber or cork), which seals the cover to the engine, and keeps any oil from leaking out.

If the gasket deteriorates, oil will begin to leak out. If the oil leaks out, your engine will not be properly lubricated, and serious engine damage can occur. Oil that leaks out through the valve cover gasket can also fall into the exhaust system and ignite an engine fire.

Without a doubt Michael is the best mechanic in Charlotte!!! He showed up an Hour early for my appointment because he knew everything I was going through was last minute and wanted to get to me as soon as possible!! My car was stranded at a friend's house and was not there when he arrived but he basically completed my service by the time I had arrived (still 40 minutes before my scheduled time) and was nice enough to look at my friends car while he was waiting on my keys to finish up with my appointment!! My friend needed almost 3 bottles of transmission fluid because it was so empty and Michael happily filled his transmission with fluid he had on him...Free of charge!! And diagnosed my friends car with his recommendations for that as well. Honestly can not say how how I am Michael is my Only mechanic!! He is probably the nicest guy ever, comes Fully equipped with everything possibly needed for mechanics, is extremely informative, best person I have met at timeliness, and is 100% trustworthy!!! If you have the luxury or getting Michael consider yourself lucky!!! Great great great guy!!!!

Although cordial, Carlos misdiagnosed my car, saying that the problem that I originally booked the appointment for was incorrect, and that I did not need to change the part I originally thought. I waited two weeks to book Carlos again and immediately after he fixed the new part he recommended, he told me that the sound was coming from the part that I booked the original appointment for two weeks prior. I expressed my frustration since I could have fixed that two weeks before when he told me that I didn't need to change the part and ended up spending $80 on an inspection that I did not want. Told me to contact company who has been AWFUL. Took me forever to explain to them that I spent an unnecessary $80, then when the person finally understood, told me that the price to fix my original problem has increased (for reasons he couldn't explain) other than saying that the actual parts went up in price, currently costing $90, when they originally and CURRENTLY (according to a quick google search) cost $37. THIS SERVICE IS NOT WORTH IT. My car is still swaying side to side and making loud noises while driving. And I'm out of over $200, and they want me to pay $90 over parts I know cost $37 on the basis that they're doing me a favor by decreasing the total cost by $80, which is money that I ALREDY SPENT. Worst experience ever.
