Watch: BEETLE ENGINE REBUILD TIMELAPSE!!!

Hagerty’s excellent “Redline Rebuild” series has been shooting timelapses of engine rebuilds and posting the result to YouTube for a while now and the weirdly calming process of seeing a dirty engine become clean is as hypnotizing as it is engaging.

After six episodes covering everything from the venerated small block Chevy to the alarmingly complicated automatic transmission from a Ford Thunderbird, the Redline Rebuilders are finally moving on to the legendary Volkswagen flat four.

After watching the rebuild, you might be tempted to go out and buy a Beetle—if you don’t already own one—just to tear the engine apart. Unfortunately, by the videomakers’ own admission, this wasn’t as easy as it looked.

“Don’t let anyone tell you that rebuilding an old Volkswagen Beetle engine is easy,” they write in the video description. “After countless hours of work, some busted knuckles, more than a few trips to the parts store, some heavy-duty Googling, and another 30,000 photos, we present our seventh Redline Rebuild time-lapse video.”

The engine in question comes from a 1972 Beetle that was found in Portland, Oregon.
