Hemi Engine Pros and Cons
In a sea of LS swaps, the name “hemi” carries a lot of emotional baggage for those retro-minded enthusiasts among us. If you’ve got a hemi, your chest might well puff up with pride, and if you don’t, you might see red when the four-letter word is uttered. As powerful as the word “hemi” is,

What Is Diesel Blow-By?
“Blow-by” is a fairly common term across all types of engines—diesel, gas, etc. For diesels, it’s when compressed air and fuel in the cylinder bore is greater than pressure in the oil pan, and gas leaks past piston rings and down into the crankcase. When this pressure in the combustion chamber becomes too great—typically during
