Frequently Asked Questions (FAQs)

1. How important is torque on valve cover bolts?

Torque on valve cover bolts is important, but it's better to undertighten than overtighten. Snugly tightening the bolts should prevent leaks, while overtightening can damage the gasket, strip threads, or crack the valve cover.

2. Will tightening valve cover bolts stop a leak?

Tightening valve cover bolts may help stop a leak, but it's not a guaranteed solution. Over-tightening can cause issues such as cracking in aluminum valve covers or warping in steel valve covers.

3. What do performance valve covers do?

Performance valve covers are designed to seal tightly, minimizing the chance of oil leakage. Some taller competition covers are available to accommodate high-performance valvetrain components. Please note that valve covers are typically sold in pairs.

4. What happens if you don't torque head bolts?

Insufficiently torqued head bolts or studs can lead to improper sealing between the heads and the engine block. This can result in cylinder pressure escaping into coolant channels or coolant entering the combustion chamber.

5. Why shouldn't you over torque fasteners?

Over-tightening fasteners can cause stripping, snapping, and failed fasteners. It's important to use the proper torque setting when installing fasteners to ensure they are secure without being excessively tightened.

6. How tight should valve covers be?

Valve covers should be tightened using a 1/4" ratchet in the palm of your hand. After a couple of times, give them a slight snug. Most manufacturers recommend tightening to inch/pound specifications, but it may not be necessary to purchase a special ratchet for measuring.

7. Will a valve cover leak if one bolt is missing?

Yes, a missing valve cover bolt can result in a bad leak. To solve the problem, it is recommended to replace the missing bolt.

8. What happens if you over tighten valve cover bolts?

Over-tightening valve cover bolts can cause the nuts and bolts to break. However, the design of the valve cover ensures that over-torquing should not distort the gaskets.

9. Do valve covers increase horsepower?

No, valve covers do not have an impact on engine performance or horsepower.
