How NOT to buy a Skid Loader!

Watch on YouTube

What happens here

Start the skid loader and let it idle. While the engine is running, remove the oil filler cap. Observe the amount of air or smoke coming out of the oil filler tube. Excessive smoke or strong air pressure (often called 'blow-by') indicates significant engine wear, potentially due to worn piston rings or cylinders. A small amount of pressure without visible smoke is generally acceptable for a healthy diesel engine.

Goal: Detect excessive crankcase pressure (blow-by) which indicates engine wear.
