In a 225 mercury outboard Can a ecu cause a motor to lean out on one cylinder and seize a piston?
Yes, a malfunctioning ECU (Engine Control Unit) can cause a motor to lean out on one cylinder, potentially leading to a seized piston. If the ECU fails to deliver the correct fuel mixture or mismanages ignition timing for that cylinder, it can result in insufficient lubrication and overheating. This situation increases the risk of piston seizure due to excessive temperatures and friction. Regular diagnostics can help identify ECU issues before they lead to severe engine damage.
What else can I help you with?
Which change would cause a freely moving piston to lower?
Increasing the pressure inside the piston cylinder would cause the piston to lower since the higher pressure pushes down on the piston.
What can cause cylinder compression in new engine?
The movement of the piston from BDC to TDC.
What causes blow by?
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
What is a piston slap?
piston slap is when the piston inside the cylinder is somewhat smaller than the cylinder bore. when the piston moves up and down, it ends up moving side to side too. this causes a knocking/slapping sound as the piston slams into the cylinder walls.this can cause harm if the play between the piston and bore are significant, otherwise it's nothing to worry about. if the car is hammering you might want to take it to a garage.Piston slap is the piston lose is the cylinder and it is making a rattling noise.Hope this helps.
What causes engine blow by?
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
Will a scratched piston effect combustion?
Yes, a scratched piston will cause problems with compression. It scratches the cylinder wall and causes wear on the rings.
Can a 1998 mercury 200efi outboard vapor lock?
Yes a 1998 mercury 200 efi outboard vapor can lock. Most of the time the issue can be traced back to the quality of fuel put into the engine that can cause the vapor to lock.
Would big end bearing knocking on ford cvh engine cause cam shaft to sound tappety due to low oil pressure affecting hydraulic tappet adjusters?
No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall.
What is the cause of bluish white smoke even after replacing piston rings and cylinder head gasket?
Oil !
The caliper on my Ford Windstar will not - retract what wrong is with it?
One cause is that the cylinder the caliper piston moves in has scores - grooves worn in the cylinder walls that the edge of the piston is catching on. One of the easiest approaches would be to replace the caliper with a remanufactured / rebuilt one.
Do piston rings rotate when engine is running?
Yes, piston rings do rotate as the engine runs, although this rotation is slight. As the piston moves up and down in the cylinder, the rings are subject to forces that cause them to rotate around the piston. This rotation helps ensure even wear and better sealing against the cylinder walls, which is essential for optimal engine performance. However, the primary motion of the piston rings is primarily linear, following the piston's movement.
What are symptoms of excessive piston to bore clearance?
excessive piston to bore clearance means that the gap (tollerance) between your piston and the sidewall of your cylinder/block is too large. usually will cause blow-by. the burning of oil, and dark exhaust smoke. also may cause the engine to have a weak compression stroke
