Solving the engine blow-by problem.
This article blogs about the causes and remedies of engine blow-by. Some of the service tips individuals and mechanics are choosing to limit blow-by are extracted from web page links in the bottoom of the article.
Solving the engine blow-by problem. What is blow-by?
Blow-by means excessive combustion and fuel vapors that contain slipped pass the engines pistons. Its nasty, cooking hot vapors then mix with all the engine oils inside a negative way.
In years pass auto makers vented blow-by by way of a vent tube to the air. Vented for the air, blow-by harms and pollutes the environment, causes breathing problems inside the young, harms vegetation, and poisons water in lakes and rivers.
In many cases, blow-by and exhaust fumes both blended with upper layers of atmosphere. There, a much more harmful chemical reaction called smog, occurs. This happens when sunlight passes through it. Smog, a stronger poison conversion of blow-by further deepens the harmful aggravation your and living things. Blow-by will not be good!
With worldwide pressures and laws, car makers were instructed to do something to prevent or control blow-by, and limit harmful exhaust. It does so with anti-smog making systems for motors. We call these “emission controls” – and all of engines will have them.
Normally, within a good engine, with clean internal conditions inside cylinder and combustion part of the motor, clean conditions limit combustions blow-by escape pass the pistons. What does escape is recycled back to the combustion for reuse. 25,000 fuel and combustion services keep your system clean.
Most engines call for a “smog service” every 25,000 miles for a standard long life. Some brands of smog service additives also end the blow-by problem. We use those brands. At links given below.
Since the blow-by term identifies excessive quantities of blow-by pressure from the crankcase – this means, resources to remove blow-by have ended taxed.
When it is your engine problem – here’s how to deal with its solution.
Blow-by can result from 3 causes:
Worn or sticky piston rings, or valve guides. Their wear gaps.
A plugged up crankcase recirculating system. Can be stopped up.
Leaking O-rings or gaskets from the pressure side of an supercharger.
For problem one, it is time for a new engine. [$4000 up]. However, additive care is available to return blow-by on track, and gain years more good life on the engine. All for a fraction of recent engine expense.
For problem two. The engine crankcase ventilation system will not be sucking out combustion blow-by. Not sending so that it is re-burnt inside the combustion cycle again. This can be from your dirty PCV Valve [under $25 replacement cost], or plugged up system orifice. Its commonly a mechanic that will stick a wire into your orifice, or spray carb cleaner into your orifice to spread out and restore its suction of crankcase blow-by fumes.
For problem three. A mechanic skilled from the supercharger system may find the troublesome gasket or o-ring, replace them, and verify leakage of pressurized air in the motor has stopped. Ending that can cause of blow-by.
In my shop, plus in my training classes for mechanics, I demo using of several additives to scrub the blow-by PCV system. These include the Mega Power Brand Emission System Service Treatment Additives. Their product include the ingredient power needed to scrub sticky piston rings – ending that blow-by cause.
Such a site can now be performed by anyone attempting to end the challenge themselves. See links below. Doing so, select product with dual, engine tune up, injector, and combustion, piston ring cleaning values. Look also for cleaners and polymers to free piston rings, and fill engine worn spaces – all aids correcting the blow-by problem.
Those cleaning procedures also lower exhaust smog pollutants. So, the service might help older engines run cleaner, with less blow-by. Such product aids passing their smog test. These 2 services [about $200 to $400 each] can certainly the engines blow-by piston and wear problem. It often avoids engine replace many years.
While these additives offer protection and lower combustion blow-by – they are unable to correct o-ring and seal, supercharger pressure system failures.
