How do I lower my 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.
How much Blowby is normal?
1.5 cubic feet per minuteHow Much Blow-By Is Normal? All engines have minor levels of blow-by, as piston rings aren't completely watertight, even in new engines. For instance, a 12-liter engine in good condition may experience 1.5 cubic feet per minute (cfm) of blow-by under normal operating temperatures.
What is excessive Blowby?
While excessive blow-by can be caused by pistons and rings that are simply worn-out or were improperly prepped during a prior rebuild, detonation, overheating or a lack of lubrication can be culprits as well, quickly destroying an otherwise perfectly good set of components.
How do you remove piston rings without removing them?

Why do piston rings blow by?
The piston rings are continuously being pushed back and forth in the cylinder wall, and with time they become worn and destroyed. This leads to leakage of gases, which causes blow-by.
How to fix a crankcase?

What happens when a piston ring explodes?
When this explosion makes its way to the crankcase through the piston rings and then out of the engine, a blow-by occurs. If the pistons are leaking and causing the blow-by, you may also notice a loss of horsepower. If not solved, blow by will cause further engine trouble and will also cause increased engine oil consumption.
Why are pistons important?
Pistons are vital for moving the crankshaft. When the pistons start wearing out, they become smaller while the cylinder walls become larger. Pistons are mostly made from aluminum – which happens to be a soft metal – when it wears out; it creates grooves in the piston while deposit accumulation occurs on the cylinder walls.
What to do if your cylinders are worn?
Replace Engine Block or Remanufacture Cylinders. If your cylinder walls have scratches and are worn, you may need to resurface them or bore bigger cylinders with bigger pistons. The other option is to replace the engine block instead.
What causes a cylinder wall to be damaged?
Damaged cylinder walls. The continuous movement of the pistons will, with time, lead to damaged or cylinder walls. It can also come from damaged pistons or piston rings. You can often notice damaged cylinder walls by listening for piston slap. Worn-out cylinder walls are not very common, luckily.
