Can too much oil cause crankcase pressure?
Think of this as your engine's way of turning cream into whipped cream. No one wants whipped cream lubricating their engine. Also of concern, the extra oil creates excessive pressure inside your engine that will look for an escape through various gaskets and seals.
What happens when a crankcase breather goes bad?
Symptoms of a Bad or Failing Positive Crankcase Ventilation (PCV) Valve. Common signs of a faulty PCV valve include excessive oil consumption, oil leaking, a blocked breather filter, and reduction in overall performance.
What happens if crankcase pressure is too high?
Increased pressure in the crankcase can cause blow-by when using a traditional push-in style breather, covering that trick engine compartment with a fine mist of fuel-oil.

Can crankcase pressure cause oil leaks?
If the engine is producing blow-by gases faster than the PCV system can dispose of them, an increasing surplus becomes trapped in the crankcase, causing excess pressure and, inevitably, oil leaks.
What happens when there is too much crankcase pressure?
Increased pressure in the crankcase can cause blow-by when using a traditional push-in style breather, covering that trick engine compartment with a fine mist of fuel-oil.
How do you reduce positive crankcase pressure?
Crankcase pressure can be prevented by protecting the piston rings. With a cold start, no oil film is yet present on the moving parts. The chance of metal-to-metal contact increases, so that the piston rings wear faster. This can be prevented with the Lindemann Engine Performance Treatment.

What can causes too much crankcase pressure?
If the engine is producing blow-by gases faster than the PCV system can dispose of them, an increasing surplus becomes trapped in the crankcase, causing excess pressure and, inevitably, oil leaks. Even the most carefully sealed gaskets leak when confronted by rising internal crankcase pressure.
How important is a crankcase vent hose?
The crankcase ventilation system is more important than people know. When there's a problem, it can cause oil sludge build-up, oil leaks, and oil consumption. Most engines have the following problems: Churning oil creates pressure.

How do you vent excessive crankcase pressure?
This usually happens when the engine is under load or at high rpm, which is when pressure builds up quickly and needs to be relieved the most. The extreme solution to prevent all of this is to install a vacuum pump that continuously draws the pressure out of the crankcase.
