A normally aspirated gas engine since a. 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.

One day I was talking to my father who was an e.

How to stop blow by in diesel engine. The Solution to Engine Blow-by. Introducing corrective maintenance into the preventative maintenance schedule extends component life and reduces unplanned maintenance costs whilst optimizing whole-of-life production performance and efficiency. Carbon is the main cause of piston ring breakage and it is easily prevented.

Keep the combustion gases and pressure where they are supposed to be and blowby wont be a concern. Since every engine has some level of blowby the crankcase needs a way to breathe. This is challenging with a turbocharged diesel vs.

A normally aspirated gas engine since a. To fix engine blow by FTC Decarbonizer is added to the diesel at each fill and you literally just drive the engine clean. The decarbonizing process is gentle and progressive but efficient even cleaning turbos and DPFs.

Most engines will also need cleaning from the oil side to restore full cleanliness to the lower piston rings as well. As mentioned check for any pressure associated with the puffs. Turn the oil cap upside down and place it over the fill tube and see if it gets blown off vibrating off is ok or place your hand over the tube and see if you can feel the puffs.

Also different oils emit different amounts of blow by smoke. To keep the crankcase from becoming pressurized causing issues with oil sealing and robbing the engine of power blow-by is pulled from the crankcase via the positive crankcase ventilation PCV system and routed back into the intake. You may be seeing the problem already.

Oil and fuel are not what you want in your air intake system. Another customer has been using the Flushing Oil Concentrate for a fair while now in older 12L Macks and Series 60 Detroit Diesels and with great success. 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. One of the reasons that can solve the answer to your question what is blow-by on a diesel engine and what causes it is the worn pistons. Unlike the cylinder walls that magnifies on wear and tear pistons tend to become smaller.

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. Check the crankcase ventilation and make sure it is clear from any dirt. In a diesel engine blow by is defined as the compressed fuelair mixture in the combustion chamber leaking past the piston and entering the crankcase.

Blow by is not good since it robs engine power and builds up gas pressure in the crankcase. There are reasons for blow by and by understanding them you can make the necessary adjustments. If applied on time XL Nanonlube will increase horsepower output reduce engine blow-by reduce oil burning and eliminate engine smoke.

It should also cool the engine smooth its functioning and reduce engine noise. XL Nanonlube works with all engines. Note that it also reduces emission because it stabilizes the engine temperature and endures very high temperatures most modern diesel.

What do I need to fix engine blow by. Engine blowby can be reduced by following 2 steps. Step 1 Simply add FTC Decarbonizer in with the diesel.

Step 2 Use Flushing Oil Concentrate when completing an oil change. To fix engine blow by FTC Decarbonizer is added to the diesel at each fill and you literally just drive the engine clean. How to Prevent Blow-By From Harming Your Engine.

The most popular way to deal with blow-by is through the use of a catch can. The name signifies what it does catching the fuel and oil blow-by after the PCV recalls it but before it ends up in your intake. The catch can suck in the excess fuel and oil condenses it and keeps it in a separate cylinder isolated from the rest of the cars engine and.

If your radiator was empty you likely have a head cracked or head gasket out. Fill it with water and see if you get bubbles at the top of radiatorwith engine running. If so it is one or both of the above problems.

Im not saying this is the cause but as coolant ages it becomes slightly acidic. Stop and go isnt so bad. I have removed the cyclone oil collector was cracked and just looped the vent to the intake.

Till I figure out a better way to collect and condense the vapor Ill send it to the intake and carry a quart of oil in the trunk. Back when I designed blow-by meters I used to collect the goo that built up in the flow meters. In a diesel engine smashed or damaged piston rings can lead to blow-by on an engine.

The grinding back and forth causes the damage causing the pistons sealing abilities to fail over time. The failure of the pistons causes the gases to be able to sneak to the back of the ring leading to blow-by on the diesel engine. Over many decades of service a W123 diesel engine is put through a lot.

Over time the piston rings and cylinder walls will not seal against each other quite as well. However how much compression blow-by you get in to your engines crank case depends a lot on how well the engine was maintained over it lifetime. Increased exhaust soot fouls turbochargers EGR valves and diesel particulate filters.

Increased oil soot chews out turbo seals. Many catastrophic failures result from neglecting blow-by. By fixing engine blow by issues engines operate with much reduced stress more efficiently and much longer.

The key to getting long life from Euro V emission. If you are running a diesel and you are on a diesel forum so Ill assume that is the case you should already be using a 40 weight oil. The number that matters once the engine is warm is the last number.

If your blow by is excessive with 40 weight oil the next step is a 50 weight oil. Oil treatment products thicken engine oil to fill these gaps and reduce blow-by through improved performance. Adding oil treatment also aids in conditioning worn dry oil seals to help stop engine oil pan and valve cover leaks.

You can add an oil treatment product to your vehicles engine with minimum automotive engine experience. David Luttrell says he fixed the blowby problem on his 1975 Ford 4400 industrial diesel engine with just a little creative plumbing. Whenever the tractor sat idling for a few minutes it would leave a puddle of oil and nasty residue on the ground Luttrell says.

One day I was talking to my father who was an e. That is called blow by. In old engines that blowby simply vented into the atmosphere via a tube called a crankcase vent tube.

The EPA found bad stuff in that blowby gas and mandated that the engines must suck up that stuff and burn it to render it harmful in some other way. Use Flushing Oil Concentrate with FTC Decarbonizer and in the vast majority of cases your engine will reduce blow-by and oil use. Low cost and the blow-by problem is solved while you continue to operate your vehicle or machine.
