What causes a car engine to blow by?
But, according to Brisbane based Cost Effective Maintenance, wear is not the most common cause of blowby. Piston ring deposits, sufficient to cause fouling in the ring groove, and/or cylinder glaze account for approximately 80% of blow-by issues.
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
How long does it take for an engine blowby pack to work?
“Over a period of 30 years, we’ve noted that, conservatively, 80% of engines that have undergone this procedure, have recovered good compression control and eliminated their blow-by.” This Blowby Pack will reduce Blowby Fumes, satisfaction guaranteed.
What can I do about a blow by engine?
These engines had developed a fair bit of blow-by and were using more oil. They found that using the Flushing Oil Concentrate reduced blow-by and oil use in the older engines. They’ve even had engines with 2 million kms respond well to the Flushing Oil Concentrate.
Why do I keep getting blow by in my car?
In some cases, you can mistake blocked crankcase ventilation for blow-by. The crankcase ventilation job is to recycle blow-by into the intake again. If the crankcase ventilation hoses are blocked, it will push it out from the oil cap once you open it, and you may think that your engine has a lot of blow-by.
What does blow by mean on a new diesel engine?
A brand new diesel engine running at full load will experience a little bit of blow-by upon startup. Blow-by is a condition where diesel fuel, air and vapor are pushed past the rings into the crankcase of the engine. Correct pressure should be maintained in the cylinder chamber in order for proper combustion to occur.
Why does my engine knock when I Blow by it?
The piston rings and cylinder walls do wear hence allowing more fuel to flow to the crankcase. Blow by can affect the intake valves. When the blow finds its way to the cylinder, it can cause the engine to knock. Knocking happens when the fuel and air mixture ignites before the spark plugs have rendered their charge.
What should I do if I Blow by my engine?
A new engine can be expensive depending on the make of the car or truck. To prevent blow by, you can opt to clean the engine and prevent further problems. If the rest of the engine components are still functioning well, you can use a flushing oil concentrate to clean the engine.
