What is the main cause of engine blow-by?

Engine blow-by is caused by compression pressure in the combustion chamber escaping into the crankcase past stuck piston rings and/or glazed cylinders, and consequently over-pressurizing the crankcase. Usually engine blow-by would suggest a very expensive engine rebuild. There is an alternative. Try the Engine Blow-by Pack first.

Blowby reduced a lot!

"I have a 2007 Volvo VNL 780 with a Volvo D12 engine. It's done a remarkable 1.6 million miles. But the blowby has been getting worse for a while now. No power loss, but oil use was really bad, and it had a lot of fumes at idle. After talking to you, I got the engine blowby pack and started using the Decarbonizer immediately, and I did the oil flush within a few days of getting it all. I did the oil flush like the instructions said - new oil, add the oil flush, fast idle for a while, then drain it. I've never seen the oil so clean! It's hard to see the new oil on the stick! Over the past few weeks I've seen a significant reduction in the blowby. I know she's done 1.6 million miles, but it is so much better now. I expect it will get better even more as I keep using the decarbonizer, and burn the carbon off the rings and cylinders. Great products!"

Engine Blowby Pack Small
"The blowby cleared up within a few weeks..."

"It's as simple as this - my Cummins ISX had only 180,000 miles since an overhaul. And now it was using oil and had pretty bad blowby too. I tried some other products that said would fix the problems but none worked. A buddy told me that he'd used FTC Decarbonizer and Flushing Oil Concentrate and had good results, so I decided I had nothing to lose. It was either try these products or it was going be another teardown. The results were amazing! The blowby cleared up within a few weeks, oil use dropped right back and is still getting better, power is up, better mileage, smoother running and idle. Everything did what was claimed to do! These products are amazing! The oil is SO clean now. It's never ever stayed clean after an oil change. I've used Cummins certified oil cleaner consistently before and it has nothing on the results I got with the oil flush. I totally recommend these products. I'm a customer for life."
