Blueprint Engine Overview

The Blueprint Engine, a remarkable creation by Norris Marshall, emerged onto the market with humble origins fueled by his passion. Initially, Marshall, almost accidentally, began crafting crate motors for fellow car racing enthusiasts. 

Intriguingly, seasoned racers in competitions quickly recognized the superior quality of these engines. Over time, Blueprint engines have seamlessly transitioned into the mainstream, evolving into high-power motors for specific types of vehicles. 

Their primary goal is to equip custom builders with the necessary tools and components, enabling them to bring their automotive dreams to life on the streets. Whether you’re seeking specific versions, Blueprint engines provide a diverse range of options to cater to your needs.

What Are the Top Blueprint Engine Issue?

Certainly, every brand of components comes with its own set of drawbacks. Whether stemming from their specific focus or the manufacturer’s quality, Blueprint engines exhibit issues that can be attributed to their usage.

For instance, a high-performance engine demands additional care and a precise setup. Without proper attention, its substantial power can potentially backfire, leading to a range of problems. Here are a few examples.

1. Durability

The durability of the Blueprint engine is a crucial aspect of our motor’s performance. It directly influences the lifespan of the engine and is a significant factor in preventing other potential issues that may have a lesser impact on our vehicle.

Regarding the durability of the Blueprint engine, there are diverse reports. The rationale behind this lies in the manufacturer’s commitment to delivering top-notch performance. Unfortunately, this reality implies that the engine may experience a quicker rate of wear and tear.

2. Issue With Oil

BluePrint engines arrive ready for installation, but crate engines may encounter oil-related issues that require prompt attention before installation and operation. Despite undergoing dyno testing, the original assembly lube on the bearing surfaces is often washed away. 

Additionally, the oil is typically drained during shipping, and by the time you receive the engine, it may arrive with a dry bearing surface. This condition can lead to significant damage caused by friction. 

Be vigilant and address these concerns promptly to ensure optimal performance and longevity of your engine.

3. Leaking Gaskets

The head gasket of an engine plays a critical role in sealing the combustion chamber, ensuring the car achieves the necessary compression for optimal engine power. Additionally, it serves to prevent the leakage of oil or coolant and safeguards the engine from overheating and potential fires.

A faulty head gasket in a Blueprinted engine can result in power loss and cause the engine to run unevenly, exhibiting symptoms such as knocking and stalling during idle. 

Many Blueprint engine owners encounter these issues due to gasket leaks, often stemming from insufficient torque or loosening during heat cycles. Recognizable symptoms include coolant puddles beneath the vehicle, a decrease in coolant levels in the reservoir, a distinct odor, and the emission of white smoke from the exhaust.

4. Wrong tune up

Setting the timing accurately is pivotal for the optimal performance of Blueprint engines. Deviating from the recommended timing specifications can jeopardize the warranty, particularly in cases where engine failure results from neglecting this crucial procedure.

Incorrect tuning, especially for new engines, may lead to various issues such as detonation, diminished power, and overheating, impacting the car’s drivability, fuel efficiency, and more. The flawless operation and durability of various engine components, including pistons, pulleys, rods, camshaft, crankshaft, timing belts, and valves, hinge on precise timing.

The initial firing of your Blueprint engine is a critical moment influencing its longevity. Given the mechanical demands of Blueprint engines, a timely ignition is essential. Firing prematurely or too late can inflict damage on cylinder walls, piston rings, and other crucial components, underscoring the importance of meticulous timing for a well-functioning and enduring engine.

5. Warranty issues

The Blueprint engine comes with warranties lasting for 30 months or 50,000 miles. Once this timeframe elapses or the mileage limit is reached, the warranty becomes void. However, additional considerations come into play. To ensure the approval of any claims, it is imperative to adhere to specific instructions.

A crucial aspect is the break-in period, which plays a significant role in identifying potential factory defects. Detecting and addressing these issues during the break-in period is essential, as they can be costly to repair later on. Being vigilant during this initial phase contributes to the long-term performance and durability of the Blueprint engine.

6. Failed Engine

In extreme situations, your Blueprint engine might experience failure, with improper break-in and the absence of oil containing a zinc additive being common culprits. Blueprint advises the use of zinc additives, especially for engines equipped with flat tappet cams. 

If your Blueprint engine has rolling cams, however, the need for zinc additives is eliminated. Instead, it is recommended to continue using break-in oil to prevent engine failure.

Regarding the break-in process, it involves wearing in the cam lobes through a 20-minute cycle, allowing the zinc oil to properly settle on the cam surfaces and mechanical lifters. This meticulous break-in procedure is crucial for maintaining the longevity and optimal performance of your Blueprint engine.

7. Overheating

Excessive combustion poses the risk of your engine overheating, which can lead to significant damage. Even a short drive with an overheated engine can have severe consequences for your car. Given the Blueprint engine’s emphasis on performance, cautious driving is essential to prevent overheating.

To mitigate the risk of overheating, two essential components come into play: a new thermostat and a bypass valve. The thermostat monitors the temperature levels, while the bypass valve releases excess heat. 

Installing and maintaining these components can help ensure optimal engine temperature regulation and contribute to the longevity of your Blueprint engine.

How to Prevent These Issues?

To steer clear of possible complications, start by thoroughly examining your crate engine upon receipt to ensure it includes all necessary installation components. Subsequently, meticulously follow all provided instructions during the installation process, as many Blueprint engine issues stem from improper installation procedures. 

Exercise caution throughout the break-in periods and when tuning up the engine. Additional maintenance recommendations include:

  • Follow Break-In Procedures: Adhere to the recommended break-in period for your Blueprint engine. This crucial phase allows components to settle and helps identify any potential factory defects early on.
  • Use Recommended Oil: Utilize the specified oil with zinc additives, especially if your engine features flat tappet cams. For engines with rolling cams, continue using break-in oil to avoid potential issues.
  • Set Timing Accurately: Precise timing is paramount for Blueprint engines. Incorrect timing can lead to a loss of power, rough idling, and other performance issues.
  • Monitor for Overheating: Given the engine’s focus on performance, overheating is a concern. Install a new thermostat and a bypass valve to regulate temperature effectively and prevent damage.
  • Regular Maintenance Checks: Conduct routine inspections and adhere to maintenance schedules. Identify and address any issues promptly to prevent them from escalating.
  • Adhere to Warranty Guidelines: Be aware of the warranty terms and conditions. Follow specific instructions to ensure your warranty remains valid and can be utilized if needed.
  • Ensure Proper Installation: When installing your Blueprint engine, ensure that all components are properly set up according to the manufacturer’s guidelines to prevent potential problems down the line.
