Large marine diesel with blowby

“I have a Detroit Series 60 Marine diesel that had a glazing problem resulting in oil blowby 2100 hours after a rebuild. I grabbed the Blowby Pack from you and started using the FTC Decarbonizer immediately. Soon after, I did an oil flush using the Flushing Oil Concentrate.  Here’s the results – after 25 hours of use the engine oil is still clean and has a slight grayish tint but still clean. The stern has no black soot and while running at 65% load there’s no dark cloud behind me. I believe it’s saved a teardown and rebuild.”
