The small block chevy has a similar problem with it’s exhaust manifold bolts.

The trick thing to do is use a locking tap washer similar to the small block chevy design on the Buick V6..

How much does it cost to replace exhaust manifold bolts?

A new gasket and hardware (nuts and bolts) will run between $50 and $100, much of the price dependent upon the size of the motor. Labor time is the real expense in this repair.

Do not use anti-seize on exposed threads because the compound can attract contaminants that may contribute to thread damage when the fastener is removed.

What is the torque on exhaust manifold bolts?

The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb. -ft. and the manifold pipe nuts spec out to 26 lb. -ft.

Is anti seize illegal on wheel studs?

But experts tell us not to use any lubricant, including anti-seize compound, on wheel studs or nuts. The tech folks at Tire Rack state: “Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. It is important NOT to lubricate hardware threads or seats.

Can you reuse exhaust manifold bolts?

You could reuse them, if you think they look good, but your chances of one breaking later have gone up now. I replace them every time, just heat the area around the studs, and melt a candle or crayon into the threads, let cool, they should come out easy, may need to heat again.

Can I use anti seize as grease?

Because of its high solids content, anti-seize can handle high load applications while still providing lubrication and friction reduction. … Yet unlike grease, the solid lubricant in anti-seize can withstand high temperatures and protect parts from galling and seizure even under extremely stressful environments.

What causes exhaust manifold bolts to break?

Each duty cycle will provide tension stress on the studs or bolts that hold the manifold in place. … This expansion and stretching of the manifold bolts over numerous duty cycles eventually causes too much tension on the bolt(s), stretching them beyond capacity and causing them to fail.

Will anti seize cause bolts to loosen?

Always use anti seize on spark plug threads and axle shafts. Some will say anti seize causes fasteners to loosen, this is NOT the case.

Do headers need to be torqued?

No. torqueing a bolt stretches it and helps keeo it tight. headers are exposed to high heating and eventual cooling. if you tighten a bolt too much it loses its elasticity and won’t hold.

How tight should header bolts be?

First pass tighten all the bolts to 11 foot pounds and then tighten them again at 18 foot pounds… before you drive the car. When using a torque wrench you should never tighten all the bolts to the final setting you work your way up to the final torque setting.

Should you use Loctite on header bolts?

NO! Do not put red Loctite on your header bolts! Bad deal all around! Depending on the gaskets you used, you may have to tighten them numerous times as the gasket takes a set.

Why do header bolts come loose?

Header bolts, if they are non-locking come loose quite often. If your bolts have a lock washer like a stage 8 bolt does then they should not come loose. However, if your exhaust system is not properly supported, the excess vibration could cause the bolts to come loose.

Can you reuse header bolts?

The stock header bolts can be reused many times. As long as the threads look good and your not wanting to spend the coin on new ones go for it.
