Just lapping some valves

Update: Since of this video's release to 12/25/17, the engine has no major problem. The engine is used to drive around 30 miles a day, and yes, I know that too much Prussian blue was used.

Tools Used:

Drill/Driver
hex to 1/4 drive
Lisle 21200 Valve Lapper
CTA Fine/Coarse Lapping Compound
Permatex Prussian Blue
Dykem Steel Blue Layout Fluid
Digital Caliper

Note: A proper valve job is recommended to be done by a professional in a machine shop. I did this because this engine is not worth much and it is not a high performance engine. (LOW BUDGET)
