1919 Buick First start since 1952
This is the first startup of this 1919 buick six roadster that had been sitting in a barn in ohio since 1952. It was parked there with a bad differential. My boss bought it on Ebay and i gently disassembled the engine, cleaned out the 50+ year old oil, freed up the piston rings and put it back together. I had to substitute a newer coil to get a strong spark and had manually filled the float bowl of the carburetor. No fuel pump was hooked up or water in the engine hence the short run time. This is a very cool early overhead valve engine with an aluminum crankcase,cast iron cylinder block, roller tappets, exposed valvetrain, zero gap piston rings, and electric start. This car had about 14,000 miles on the odometer. Enjoy the video! Check out my other video/slide show for engine disassembly pictures.





Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 118 cycles per second is an amazing sight (and sound)
