Only wet sump engines have drain holes. Two strokes and four strokes with oil tanks do not, they are dry sump engines.
Yes you can, as a mater of fact that is what is done in two stroke engines that dont have a sump.
Not all 4 stroke engines are upright. How about the Chevrolet Corvair, the air cooled VW, a typical vertical shaft lawn mower. It doesn't matter as long as the oil sump/reservoir is located at the bottom.
Four stroke engines use an oil sump, and do not need to have oil mixed into their fuel.
They will run (poorly) on it. Four stroke engines have a sump to hold the oil so none is needed in the fuel
A dry sump is not submerged under water as a wet sump is. a dry sump uses a resivoir to hold the oil much like the brake fluid. a wet sump has the oil sump bolted to the bottom of the engine block :D
Acrobatic aircraft typically do not have carburetors. The engines are fuel injected. The engines are designed to operate upside down by having an external oil sump that keeps the oil pump continuously submerged, too.
haha on the sump
Bottom of the sump?
On 1998 year ,The sump plug is on the bottom of sump at the rear right.
Oil drain plug is on the left side on bottom of oil tank. Dry sump engines do not have drain plug on engine.
Test it with a magnet.
