Heavy D's cabover engine reaches the rotating assembly for Sparks Motors
The week's only upload went to Your Diesel Specialists to watch the rebuild come together, and it passed 160,000 views in under two days.
Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
TOTAL REBUILD! Heavy D’s Cabover Engine Assembly.
Sparks Motors put out one video this week, and it went to the machine shop. "TOTAL REBUILD! Heavy D's Cabover Engine Assembly." follows Heavy D's cabover engine at Your Diesel Specialists as it reaches the rotating assembly stage. The description bills it as a close look at how a veteran of the trades approaches a build, and which details matter.
It drew about 110,000 views in its first day and had passed 160,000 within two. In the comments, viewers keep coming back to the man doing the work. Several admit they will never build a truck engine themselves but say they know how now. One diesel mechanic writes in to say he is not easily impressed and this did it. Another reader spots what may be an old truck in the background. One sharper question asks whether checking the bearing gap just isn't done on truck engines.
The Kenworth is still rolling too. "BIG RIG BUILD! The Most Insane Kenworth Build You've Ever Seen", the custom Road Warrior truck meant to go to one nominated driver, is sixteen days old and nearing half a million views. The second garage sale video, with Heavy D clearing out the lot, has mostly settled down.
The channel as a whole ran a little above its usual daily pace. That puts it in the minority among the car channels near its size, where Speed Academy, Garbage Time, Rainman Ray's Repairs and Dennis Collins are all running well below their norms. Top Gear Classic, meanwhile, keeps up its usual big numbers.
