How to fix Engine Blowby

Published 2020-05-21
Most drivers can easily tell when thing aren’t quite right, for example, the engine is…

Getting tired and down on power
Starting to breathe heavy
Using more oil than usual
Excess exhaust smoke

Engine blow-by, smoke and oil use are related issues that, if ignored, can turn into very expensive repairs. Fortunately, in over 80% of cases this can be corrected at low cost, and without any downtime.

    I have always emptied a couple of litres of oil out of the sump, topped up with diesel fuel, run 5 minutes then drain the lot. Add new oil and filter. No more blowby.

    I have been using these products for 11 years in all my machinery. I bought my MN 2.5 litre diesel Triton new in 2010 and it now has 537,000 kms on the clock and does not burn one drop of oil between 15,000 km services , it still runs the original injectors and still pulls like a freight train ! A very good Australian product. Highly recommend CEM.
  • Can I use this safely if I barely have blow by or close to none at all on a gasoline engine?

    Warning! Use as directed! Do not go cheap, and use with old oil and filter! Use new oil, even if cheap, and filter! I went cheap, as I just put in a lot of money in engine work. So, I added the Oil additive to oil I was going to be changing out. Ran it for 45 minutes at 1200 rpms, as directed. Then I idled it, while waiting to get in shop at normal idle. My oil pressure warning went on, oil pressure dropped to 0, shut engine off warning came on. They drained oil. It was sludge! Pulled apart oil filter. Gunked up... threw in new, but cheap oil, let run 10 minutes. It looked like sludge. Black sludge! That stuff cleans out every thing! Definitely use new oil, not old! My mistake. I figured it was expensive, especially with FTC Decarbonizer I added to fuel, and the Valvoline Restore I bought for the oil change at $85 per gallon! Well, cheapest oil was $25 per gallon, as of recent, so I went cheap. Don't do it! Change Crank Case filter too! So, in went the Restore oil, and hopefully that cleans out whatever is left, along with using the FTC, and in 12-15k, going to straight Valvoline Premium Blue. The mechanic dropped the pan, checked the bearings, liners, etc, and said it looked real clean!

    Where they apply flushing oil concentrate on the oil engine?

    My 7.3 power stroke has 262k miles. It does not burn any oil but does have a decent amount of blow by. Do you recommend this product for my situation? Thanks
  • @TheRyadrian
    wouldnt oil sludge prevent blowby? Im so confused. Like oil sludge will literally block the passage between rings and cylinder walls so removing the blockage....would send more oil up?
  • @jmilko917
    I used Lucas oil stabilizer and it almost completely eliminated blow by in my 6.0
  • @brettpowter6010
    Great product but cant see how it can clean turbos as the fuel goes nowhere near the turbo??
  • @invig2
    How about VW Jetta TDI? Can I purchase a smaller amount?
  • @jacobprince5474
    Traded this Cummins I had with quite a bit of blow by for a duramax I did a blow by test and had no blow by a couple hundred miles I did it again and it puffed the cap up I don’t understand how this could happen over a couple hundred miles
