Leakage can happen due to low joint articulation.
Select ball joint articulation of 50 degree all around.
Leakage may happen in the absence of clamping for rubber boot.
Select ball joint rubber boot with positive clamping arrangement.
Vacuum leaks on any vehicle are found by spraying the suspect joints or connections with WD40 or other lubricant (NO SILICONE BASED LUBRICANTS) with the engine idling. When the idle changes you've found the leak. If you suffer a brain freeze and use a silicone based lubricant you will kill the oxygen sensor.
Could be a hole or leak at one of the joints or cylinder head bolts / nuts.
A leak.
leak free joints are provided
Gasoline, water from the exhaust, lubricant from the rear differential.
Broken or split hose Radiator leak heater core leak
Most connections / joints between parts have a gasket to prevent leaks. So a failed gasket is a typical cause of leaks, including where the exhaust pipes connects to the exhaust manifold.
Corrosion.
A battery can leak when its casing is damaged or when it is exposed to extreme temperatures, causing the internal chemicals to react and leak out.
A small leak in the vapor system from the tank to the engine.
Under the vehicle, on the side of the transmission, there should be a plug that you can remove to chek/add lubricant. You should be able to stick in your fingertip to feel for lubricant. If lubricant is needed, you will need a siphon-type pump to transfer the lubricant from the container to the transmission. When the transmission reaches the level of the hole and starts to leak out, the transmission is full.
so air won't leak out of the ball before you even use it.
