What Is Blowby? What Is Too Much Blowby?

Every engine produces blowby, but too much of it can be an indicator of cylinder damage or other engine wear. This video goes into what blowby is, how to troubleshoot it, and how important blowby is. Any questions can be left in the comment section and I try to answer the comments.

This is my first time viewing your videos and I have to say I am now a fan! Great info! I used to work on Caterpillar truck engines in late 90's early 2000's and have seen this myself. I remember getting some with a scored cylinder pack that would puff fumes out of the blowby tube every time that cylinder fired. I miss working on these engines since I have been out of the game for almost 12 years but I am slowly working back into it looking to re-start my career in diesel repair.

Your videos have been very helpful I just wish I had seen them sooner. There is a lot of things some shops can't check but they won't tell you or they don't know how. They were also enlightened. At my expense.

Great videos. I deal with CAT engines all day in the military so it was pretty awesome stumbling across your channel.

Thought I'd mention that different engine manufactures run this test differently, i.e. idle no load to high idle no load. Just so the viewer knows but depending on engine manufacture you can have other causes of high blowby. Such as a bad air-compressor. A leaking intake manifold/valve cover gasket bad oil seperator. It's getting to the point now a days that the rule of thumb is getting thrown out the window. Love your videos keep them coming. :)
