It is one of the most commonly asked questions by car owners, and yes, you should torque your valve cover but make sure you do not over torque it to break it. Also, it would be best if you took care that you need only a minimum to keep the covers from leaking.
Some experts suggest that you can torque valve covers up to 7 lb. ft. Thus if you are unsure what the valve cover torque specs are or do not know how to do it. Then, in this case, you can take the help of professionals, as they have better knowledge and tools than you.

What Is The Torque For Valve Cover Bolts?
There are many types of valve cover bolts with varying torque specifications. For example, stud bolts typically require the most torque, while rocker cover bolts require the least.
First, the most popular type of bolt is the stud bolt. The typical stud bolt has a nut and a threaded steel insert that slides into a hole in the head. The nut threads on from the front and tightens against a plate underneath the engine, which keeps oil from pouring out of the hole.
An easy way to get around this is to use new torque-concentrated nuts that hold your old ones in place. This allows you to screw down the new nuts evenly, even more so if they’re a bigger size.
However, if you don’t want to spend money on a set of torque-concentrated nuts that are usually very expensive, there is an easy way to do it. You can use a furniture loosener and tighten your stud bolts after loosening them up with the loosened ones.
There are two solutions in these situations: one is to use rocker studs; the other is rollers. Rocker studs are best for simple bolt jobs under 300 pounds per inch (PSI).
If you need torque greater than that, then rollers are best. They have a flange that allows you to use a wider range of bolts and a wider contact area.
How Do You Torque A Valve Cover?
Have you ever found yourself trying to take off a valve cover and wondering what you’re doing wrong? Do you have a wrench in there with your hands and no idea where to begin? Here are the proper steps to torque or tighten the valve cover:
- First, you need a torque wrench. Take the torque wrench and set it up from 4 to newton meters square. These are the suggested specs for your torque wrench, and make sure you do not overdo it.
- Now, you have to tighten the bolts of the valve cover, including this wrench. Rotate the wrench on the inward side to tighten it. You have to keep tightening it until you hear a clicking sound.
- You have to repeat the same process with all the bolts.
- Now, it’s time to change the wrench setting from 7 to 10-newton meters per square.
- Once again, tighten all the bolts with the wrench until you hear a clicking sound.
That’s it; these are five simple and easy steps that anyone can follow to tighten or torque the valve cover bolts. It is necessary to know the process of torquing the valve cover as if you overdo it, you can damage the bolts, and you may then have to replace it. This increases the cost of repairing.
So, if you are still confused and worried about the process of torquing valve cover bolts, just follow these simple steps, which will ensure that you don’t get any damage done to your car while fixing this issue.
Or it is advisable to take it with a qualified technician as he will help you do the job without damaging the bolts.
What Happens If you Over tighten A Gasket?
When you try to tighten the gasket, there is always the risk of over-tightening it, which everybody seems to forget. They overlook this risk as they do not know that it can severely cause some further damage to the gasket and other parts of the car.
So when you over-tighten or over-torque the gasket, the flange load can be unbearable. It thus put increases the blowout pressure, which can be the reason for gasket failure or joint damage. It can also cause full gasket failure and leakage in your car.
To avoid this scenario, you must follow the proper tightening method specified by the gasket manufacturer. But often you don’t have any idea of it.
Другая проблема, с которой сталкиваются некоторые люди, заключается в том, что они не знают правильных характеристик инструментов для затягивания прокладки.
This makes the problem more complex as those who are not aware of the tightening method of the gasket may often fail to identify whether the old gasket or new one is fitted on the car or not.
The guys from schlüsseldienst Berlin recommend, to avoid such issues, always use new gaskets for your car and follow its manufacturer’s recommended torque value in every case.
Can You Over-Tighten Valve Covers?
Yes. If you tighten the valve covers, there is always the risk of overtightening it. Once the shoulders area hits bottom with the head, that’s it; you can stop tightening as any more tightening can damage valve covers and break the bolt’s tip. Once the bolt is broken, you can’t do a thing about it.
Some insist on using new and untouched valve covers for tightening purposes. Unfortunately, once the bolt touches the bottom point, it is impossible to tighten it further without breaking or damaging something.
If you have a professional mechanic to put them in or if there is no other option, then use some vice-grips, place them on valve covers and tighten them enough where they do not fall off.
What Are Valve Cover Gaskets?
Valve cover gaskets are components made of either plastic or rubber to protect the engine and other hardware of the car from several elements. It also helps in preventing the leak of oil from the engine. However, today, they are not considered the end to the oil leakage problem.
Valve covers gaskets have been used on engines since the time of early cars. They were used to protect valves and other essential parts against engine wear.
This is because valve wear was a common problem at that time. These gaskets also helped prevent leaking oil out of the engine.
The gasket would seal the valve tightly whenever it was closed, making it completely impervious to all kinds of elements from the outside world.
Valve covers gaskets create a tight seal by forcing the oil around it to make a thicker layer than the surrounding area. This will help seal off all the oil and exhaust gases from flowing out of the engine.
Today, they are not considered the end to the oil leakage problem. The gasket should be replaced every time one develops a leak. This is because its duration of use will vary depending on how long it has been stored before being put down for maintenance.
