Customer Questions
Will an engine flush clean my pistons?
No, an engine flush is unlikely to clean the pistons.
How to replace engine pistons?
Replacing engine pistons involves removing the engine from the vehicle, disassembling it, removing the pistons, inspecting the engine components, installing the new pistons, reassembling the engine, and testing it. It's a complex process that should only be attempted by experienced mechanics.
When do engine pistons rings go bad?
Engine piston rings can go bad due to wear and tear, inadequate lubrication, overheating, manufacturing defects, or improper installation. Symptoms of failing piston rings include reduced engine power, increased oil consumption, and blue smoke from the exhaust. Regular maintenance and inspection can help identify potential issues.
Why do engine piston rings fail?
Engine piston rings can fail due to wear and tear, inadequate lubrication, overheating, manufacturing defects, or improper installation. Regular maintenance and inspection of the engine can help identify potential issues. Symptoms of failing piston rings include reduced engine power, increased oil consumption, and blue smoke from the exhaust.
Can you replace engine pistons rings without removing the engine?
Replacing engine piston rings without removing the engine is possible but not recommended due to the extensive disassembly required and the risk of damaging other engine components. A full rebuild or overhaul is generally more efficient and effective.
What size Edelbrock carburetor do I need?
The size of the Edelbrock carburetor you need depends on several factors, including your engine's displacement, performance goals, and intended usage. It is recommended to consult Edelbrock's carburetor sizing guidelines or seek advice from a knowledgeable professional to determine the appropriate carburetor size for your specific application.
Why is my Edelbrock carb flooding?
Several reasons can cause an Edelbrock carburetor to flood, including issues with the float level, needle and seat, or fuel pressure regulator.
How does the Edelbrock electric choke work?
The Edelbrock electric choke uses an electric heating element to control the opening and closing of the choke plate, allowing for automatic choke operation based on engine temperature.
Are Edelbrock carbs square bore?
Yes, most Edelbrock carburetors are designed as square bore carburetors.
Are oil pump gears necessary?
Yes, oil pump gears are essential for maintaining proper engine lubrication in an internal combustion engine.
How do oil pumps work?
Oil pumps work by creating pressure to circulate engine oil throughout an internal combustion engine.
Where is the oil pump located?
The oil pump is typically located inside the engine's lower oil pan or sump.
Why do oil pump failures happen?
Oil pump failures can arise from wear, contamination, poor maintenance, and manufacturing defects, causing inadequate lubrication and potential engine damage.
