I would first change the pcv valve.Its cheap[ and would cause oil to leak in alot of places because of crank case pressure.

Seems the flexpipe leaks at the ends...
The common vacuum leaks on the 2004 Trailblazer are usually from the dashboard. It is therefore important to service them regularly.
If you have leaks in a water bottle rocket, the pressure will quickly escape along with the water and the rocket won't be able to reach as high an altitude as a rocket without leaks.
Heat can escape from houses through conduction, convection, and radiation. Common pathways include windows, walls, roofs, floors, and gaps around doors. Proper insulation, sealing leaks, and using energy-efficient windows and doors can help prevent heat loss from homes.
The most common place for oil leaks is the sump/crankcase cover gasket. A torn gasket will allow oil to escape. A common cause could be a blown head gasket putting too much pressure in the crankcase.
Air pressure escapes through openings like doors, windows, or vents. It can also escape through leaks in a system or container that is under pressure.
I'm pretty sure it's common
These are common for oil pan gaskets, if the oil level is a quart low it most likely isn't high enough to leak out the gasket
There's really no link between the two events.
A crack, crevice, fissure, or hole which admits water or other fluid, or lets it escape; as, a leak in a roof; a leak in a boat; a leak in a gas pipe., The entrance or escape of a fluid through a crack, fissure, or other aperture; as, the leak gained on the ship's pumps., Leaky., To let water or other fluid in or out through a hole, crevice, etc.; as, the cask leaks; the roof leaks; the boat leaks., To enter or escape, as a fluid, through a hole, crevice, etc. ; to pass gradually into, or out of, something; -- usually with in or out.
Common causes of boiler leaks include corrosion, pressure issues, and faulty seals. To prevent leaks, regular maintenance, monitoring pressure levels, and promptly addressing any issues can help maintain the integrity of the boiler system.
