Often asked: How Many Times Can You Reuse Main Cap Fasteners On Ls Motors?

Can you reuse 5.3 rod bolts?

You can reuse the bolts. The stock rods are weak and usually break just above the large radius (no aftermarket (ARP) bolt will stop it) If the rods are out, you should replace them with Compstar or equivalent/better; if you can afford it.

Can I reuse connecting rod nuts?

It’s OK to re-use rod bolts and nuts. I always fit the nuts back onto their original bolts. ARP recommend you tighten/release the nuts a few times with their moly lubricant to seat the threads together. If you put a nut back on the same bolt,it’s already seated.

Are LS main cap bolts torque to yield?

They are torque to yield and must be replaced. Might as well throw in some ARP hardware. 1.301 best 60FT getting there!

Are ARP LS head bolts reusable?

Are ARP bolts and studs re-usable? Yes. As long as the fasteners have been installed and torqued correctly, and show no visible signs of damage, they can be re-used. If they show any signs of thread galling or corrosion, they should be replaced.

Should you replace con rod bolts?

While plenty of people do re-use them I strongly advise against it. They are one of the most highly stressed components in a motor and while not a ‘Torque to yield’ item the Guzzi bolt are difficult to measure accurately for stretch and are actually torque specified. Nuts are fine. I always replace bolts though.

Can you reuse Duramax rod bolts?

Yes you can reuse all the rod and main bolts sibling as they look good.

Are crank bolts reusable?

They can be reused IF they are torqued properly.

Can you reuse torque to yield rod bolts?

Once the torque-to-yield fasteners are torqued, go through different heat cycles, and are subjected to stretching due to material expansion, they never return to their original length. For this reason, you should never reuse a TTY head bolt.

Can you reuse big end bolts?

No you shouldn’t re use them. Buy new ones. They aren’t very expensive and you don’t want your engine to go bang in a horrendous way if one of the fails do you.

Are ARP bolts worth it?

The precision and extra strength of ARP means the sockets fit better and the metal on the fastener won’t strip. And ARP mean your mill will live longer and have fewer problems than with stock style bolts. It’s worth it. Better, more consistent clamping on head gaskets, rod bolts, etc.

What happens if you reuse LS head bolts?

The one universal law for any engine whether or not a cylinder head bolt can be reused is what condition is it in. Chasing damaged head bolt threads with a die will clean up the threads but also remove material (metal) and undermine the head bolt’s ability to torque down and hold to specs.

How many times can I reuse ARP head studs?

ARP studs are not torque to yield so you can tighten them as many times as you want with out damage. The only time you would do damage to them is if you over tighten them and stretch them permanently rather than just elastically.
