Can-Am Engine Studs: What You Need to Know

When embarking on an engine upgrade or rebuild for your Can-Am vehicle, understanding the specifics of what comes included can save you time, money, and potential headaches. One common question that arises, particularly when dealing with performance enhancements or replacement engines, is whether Can-Am engines are supplied with exhaust studs. This seemingly small detail can have implications for installation and overall project planning. Let's delve into this topic to provide clarity for enthusiasts and mechanics alike.

Do Can-Am Engines Come with Exhaust Studs?

The direct answer to whether Can-Am engines come with exhaust studs is nuanced: sometimes, but not reliably. As stated in the provided information, engines may or may not come with exhaust, head, and gearbox studs. The supplier explicitly mentions, "We don't install nor remove them from cores." This implies that the presence of studs on a core engine is dependent on the condition of the engine when it was acquired as a core. Furthermore, they draw a parallel to engines purchased directly from a dealer, noting, "If you buy an engine from your dealer it will show up with no studs as well." This suggests that studs are often considered separate components or are removed during the sourcing of core engines for rebuilds. Therefore, it's prudent to assume that your replacement or rebuilt engine might not include these essential fasteners.

Why Are Exhaust Studs Important?

Exhaust studs are critical for securely attaching the exhaust manifold or header to the cylinder head. They offer several advantages over traditional bolts:

• Even Clamping Force: Studs allow for more uniform pressure distribution around the exhaust port, reducing the risk of leaks and warping of the manifold.
• Ease of Installation/Removal: When installing or removing an exhaust system, studs simplify the process. You can thread nuts onto the studs rather than having to manoeuvre a bolt into a tight space on the cylinder head.
• Durability: They are typically made from robust materials designed to withstand the high temperatures and vibrations associated with exhaust systems, preventing premature failure.

What to Do If Your Engine Doesn't Come with Studs

If your Can-Am engine arrives without exhaust studs, or if you're preparing a core for rebuild and want to ensure they are present, you will need to source them separately. It is highly recommended to purchase high-quality, heat-resistant studs specifically designed for your Can-Am model. Consulting with the engine builder or a reputable aftermarket parts supplier is advisable to ensure you get the correct size, thread pitch, and material.

Purchasing Replacement Studs

When buying new studs, consider the following:

• Material: Look for studs made from high-strength, heat-resistant alloys like stainless steel or specific grades of hardened steel that can endure the extreme temperatures of the exhaust system.
• Thread Pitch: Ensure the threads match both the cylinder head and the exhaust manifold/header precisely.
• Length: The studs need to be long enough to provide adequate thread engagement in the cylinder head and allow for the exhaust manifold and nuts.
• Quantity: Determine the exact number of studs required for your specific engine configuration.

Warranty Considerations for Can-Am Engines

The provided information highlights crucial aspects of engine warranties that directly impact owners. A significant point is that aftermarket crank engines will not be warranted. This means if your engine build involves a non-factory crankshaft, any warranty claims will be invalid. For full engine builds, a 100-day warranty is offered from the delivery date. However, this warranty is conditional:

• Professional Installation is MANDATORY: "All engines be professionally installed for your warranty to be valid. No exceptions!" This is to ensure correct procedures and fluid usage. Proof of professional installation via a detailed invoice or receipt is required.
• What is Covered: The warranty covers the engine itself.
• What is NOT Covered: Shipping costs, labour on your end, forced induction builds (nitrous, turbos unless stock, superchargers), oil starvation, overheating, water/mud/sand ingestion, and detonation from poor tuning are explicitly excluded.
• Tampering Voids Warranty: If the engine has been disassembled before being received by the builder, the warranty is void.

It's vital to adhere strictly to these warranty terms to protect your investment. The requirement for professional installation underscores the importance of correct engine mounting and initial setup.

The Expertise of EVP: A Leader in Powersports Engine Building

The mention of EVP (Extreme Velocity Performance) in the context of engine building is noteworthy. With over 50 years of combined engine-building knowledge, EVP has established itself as a dominant force in UTV racing. Their success is evident in numerous podium finishes across various sanctioned racing series, from grassroots enthusiasts to factory-sponsored teams. EVP-built engines are recognized for their performance and reliability, consistently bringing home championships. Their achievements in series like the Sand Outlaws, Southern Bounty Mud Series, and their holding of world records in top-speed and eighth-mile events speak volumes about their capabilities. When considering an engine rebuild or a high-performance engine, the track record of a builder like EVP is a strong indicator of quality and expertise.

When to Call or Message Before Ordering

The advice to "CALL OR MESSAGE BEFORE ORDERING ANY BIG BORE BUILD TO CHECK STOCK!" is a critical piece of pre-purchase advice. Big bore kits and custom engine builds often involve specialised components and can be subject to availability. Proactively contacting the supplier ensures that the parts and expertise required for your specific build are in stock, preventing delays and disappointment.

Frequently Asked Questions

Q1: Will my new Can-Am engine definitely come with exhaust studs?
No, it's not guaranteed. Engines may or may not come with studs, and it's common for them not to, especially if sourced as cores or from a dealer.

Q2: What kind of studs should I buy if mine are missing?
You should purchase high-quality, heat-resistant studs specifically designed for your Can-Am model. Consult with your engine builder or a reputable parts supplier for the correct specifications.

Q3: Does the warranty cover installation labour?
No, the warranty explicitly states that labour on your end is not covered. It also does not cover shipping.

Q4: What happens if I install the engine myself?
If you install the engine yourself, your warranty will be void. Professional installation with proof is a strict requirement for warranty validity.

Q5: Are modified engines covered by warranty?
Aftermarket crank engines are not warranted. Forced induction builds (turbo, supercharger, nitrous) are also not covered, unless the stock build was already turbocharged.

Conclusion

In summary, while the presence of exhaust studs on Can-Am engines is not a certainty, understanding this potential omission allows for proper preparation. Always plan to source high-quality studs if they are not included. Furthermore, paying close attention to warranty terms, particularly the absolute requirement for professional installation, is paramount for protecting your engine purchase. For those seeking top-tier performance and reliability, the expertise of renowned builders like EVP offers a proven path to success on the track or trail. By being informed and proactive, you can ensure a smoother and more successful engine project for your Can-Am.
