Product Questions (9)

Customer Questions

Will an engine flush clean my pistons?

No, an engine flush is unlikely to clean the pistons.

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.

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.

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.

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.
