Frequent question: Do you need to torque rocker cover bolts?

Should you torque valve cover bolts?

Tighten until your hand can’t tighten anymore (which SHOULDN’T be too tight) And that should be just tight enough. Any tighter and you risk busting a bolt.

What is the torque setting for valve cover bolts?

Torque the valve cover bolts to 5-6 ft/lbs, making sure gaskets do not slip out of position. Proper torqueing will help to ensure that your covers do not leak oil.

Do valve cover bolts come loose?

Lock washers keep tension on the bolts so they won’t loosen. The aluminum covers will expand and contract easier with heat causing the bolts to loosen, if they are not under tension.

Do you need to torque bolts?

In simple terms, you need torque to create tension in a bolt. You use torque to turn a nut onto a bolt and then to stretch the bolt, making it a solid spring that clamps the two materials together.

Do you use Loctite on valve cover bolts?

The proper bolt for valve cover has radial ridges or splines running from center to outside, no washer, no Loctite.

Can tightening valve cover Stop Leak?

Before tearing everything apart, first try gently cinching down the valve cover bolts or use a torque wrench. Over-tightening bolts will not stop bad gaskets from leaking. Aluminum valve covers can crack.

What are valve cover gaskets?

What is a valve cover gasket? A valve cover gasket seals the valve cover to the top portion of the engine cylinder head. The gasket prevents motor oil from leaking out as it travels around the camshafts, rockers and valves.

What happens if you don’t torque bolts?

Insufficient torque

Alternatively, the engine’s vibrations can cause the bolt or nut to come undone, displacing the tensioner. This, in turn, will lead to incorrect belt tension and, eventually, to belt and/or engine damage.

Are torquing bolts important?

those nuts that keep your wheel fastened to the studs on your axle and the bolts that secure and keep your engine assembled were installed at the proper torque to keep them from coming loose. When accurate torque is not applied to the bolts and nuts, they wear out quickly and can cause failure.
