Engine Blowby Kit

Description

I was reading Big Rigs at work one night when I came across the Advert that stated “save $24000 on Detroit 60 Engine Rebuild…” After applying the product, I was in awe at the performance I was receiving from the truck after a few hours of working. The “TOECUTTER” was running smoother and cooler, not using oil, and overall the performance is truly unbelievable. To read Richo’s full story CLICK HERE

What Is Blow‑By in a Diesel Engine?

Blow-by in a diesel engine happens when combustion gases leak past the piston rings and enter the crankcase. This creates unwanted pressure that pushes oil vapour through the breather system.

A small amount of blow by is normal in any internal combustion engine. But excessive engine blow-by becomes a problem when it leads to visible vapour, increased oil consumption, and reduced engine performance.

You’ll often notice:

• Vapour or fumes escaping from the breather
• Dropping oil levels and more frequent top-ups
• Loss of power and more exhaust smoke

In many engines, this doesn’t necessarily mean worn-out engine components yet. Instead, it’s often caused by carbon buildup and hardened deposits that stop the rings from sealing properly.

Symptoms of Blow‑By – How to Tell if Your Engine Has a Problem

Blow-by in a diesel engine builds slowly over time as carbon and sludge accumulate inside the engine system.

Some common signs of it include:

• Visible vapour from the crankcase breather or oil filler
• Increasing oil use and oil mist around the engine bay
• More exhaust smoke, especially under load
• Loss of power and reduced efficiency
• EGR and DPF issues caused by excess carbon, soot, and unburned fuel

If left untreated, engine blow issues can lead to oil contamination. It can also result in reduced lubrication due to a weakened oil film, and eventually in expensive repairs or even a full rebuild.

Why Carbon and Sludge Cause Blow‑By (Before the Engine Is Worn Out)

Most people are told that blowby means worn piston rings and that a rebuild is the only fix. But in many cases, that’s simply not true.

Inside the cylinders, carbon deposits and sludge can build up around the pistons and rings. This can stop them from sealing tightly against the cylinder wall.

If this happens, it creates:

• Reduced compression and higher cylinder pressure loss
• Increased oil getting past the rings
• More fuel and gases leaking into the crankcase

When piston ring issues are caused by buildup rather than wear, then cleaning the deposits can restore sealing and reduce blow-by without pulling the engine apart.

What’s in the Engine Blowby Kit?

CEM’s Engine Blowby Kit is designed to fix blow-by at the source. Specifically, it does this by cleaning the combustion chamber and restoring ring function before you consider a rebuild.

FTC Decarbonizer (Fuel Treatment)

Added directly to your diesel, FTC Decarbonizer works through the fuel system to clean carbon from the combustion area. It helps to:

• Remove carbon buildup from valves, injectors, and turbo
• Clean the intake and reduce soot entering the DPF
• Restore cleaner combustion and improve engine performance

Flushing Oil Concentrate (Engine Flush)

Used during an oil change, the flushing oil concentrate cleans internal engine components. It works to:

• Dissolve the sludge and deposits inside the engine
• Free stuck oil control rings
• Restore proper oil flow and reduce blowby pressure

Together, this system targets both sides of the problem. In other words, fuel-side carbon and oil-side sludge.

How to Use the Engine Blowby Kit (Step‑by‑Step)

If you want to get the most out of the Engine Blowby Kit, here is a simple, proven process to follow. Each step is designed to clean parts of the key engine areas. It will also restore piston ring sealing and reduce blow by without dismantling your diesel engine.

Here’s how to apply the treatment correctly for the best possible results.

Step 1: Add FTC Decarbonizer

Add FTC to your fuel tank before a normal drive or work cycle. As the engine runs, it cleans carbon from the combustion chamber. This helps to free stuck rings and improves their sealing.

Step 2: Use Flushing Oil Concentrate

Before your next oil change, add the flush to the existing oil. Let the engine run as directed, then drain while hot to remove loosened deposits.

This helps clean oil-wetted components and restore proper ring function.

Step 3: Refill and Monitor

Refill with fresh oil and monitor results. Most users report:

• Reduced visible blow by
• Lower oil consumption
• Cleaner exhaust with less smoke
• Improved power and smoother operation

Should internal parts be heavily worn or damaged, a rebuild may still be needed. However, many engines respond well and avoid major work.

Engine Blowby Kit Results – Before You Rebuild

Across Australia, this kit has helped vehicles, trucks, and machinery to avoid costly rebuilds.

Typically, results include:

• Reduced blowby and crankcase pressure
• Cleaner engine internals and less carbon buildup
• Improved fuel efficiency and smoother running
• Extended engine life without replacing major components

Many customers find their engine returns to normal operation after cleaning. This gives them more time before considering expensive repairs.

FAQs

What is blow-by in a diesel engine?

Blow-by is when combustion gases leak past the piston rings into the crankcase, creating pressure and forcing oil vapour out.

Will blow-by damage my engine?

Yes. Excessive blow by can lead to oil contamination, increased wear, reduced lubrication, and eventually serious engine damage.

Can the Engine Blowby Kit fix all problems?

No. If there is physical damage to cylinders or rings, parts may need to be replaced. The kit works best when the buildup is the main issue.

How quickly will I see results?

Some engines improve within one treatment cycle, while others may need a second clean depending on the level of buildup.

Is the Engine Blow By Kit safe for modern diesel engines?

Yes. The system is designed for modern engines, including those with DPF and EGR systems, when used as directed.

Will it improve engine performance?

In many cases, yes. Cleaning deposits can restore sealing, improve compression, and increase overall engine efficiency.

Should I still use quality oil and regular maintenance?

The Engine Blowby Kit is designed to prevent blow-by through proper maintenance. Using quality oil, changing it at the correct intervals, and keeping your engine system clean will all help to maintain proper sealing. This kind of ongoing care is key to protecting engine components and preventing the problem from returning.

 

“Cummins said it was a rebuild!

Fitted with a Cummins 444, Maslin Bros Pty Ltd used their T650 Kenworth daily on a contract with a Mt Isa mine site. The truck lost power and started smoking so badly, that it was black banned from site. The local Cummins dealer told Hugh Maslin that there was way too much blow by, and it would need rebuilding. 

Instead, Hugh tried FTC Decarbonizer and Flushing Oil Concentrate. He was absolutely amazed at how much rubbish came out on the flush. After the treatments, the Kenworth went back to work, for the remaining 18 months of the contract…with no smoke and no oil usage!!

Two years later, and the Kenworth still showed no signs of deterioration. Hugh had saved the business a rebuild, didn’t lose any downtime, and kept his client happy.
