What is crankcase pressure?
What is crankcase pressure? Quite simply, it’s the pressure above atmospheric (or positive pressure) in your engine’s crankcase. If you were to place a pressure sensor or pressure gauge on the crankcase of your engine, you could measure the amount of crankcase pressure developed in your engine.
How do you vent crankcase pressure?
What is the best way to vent the crankcase and valve cover?
- Empty your pockets for a Dry Sump System.
- Belt or Electric Vacuum Pump.
- Adding ports to the crankcase and valve cover.
- Adding ports to atmospheric vents.
Can a bad turbo cause crankcase pressure?
The intake manifold is under pressure during most running conditions when an engine is turbocharged. The gas and oil bypassing the rings are still present, and the pressure generated by the turbocharger can increase crankcase pressures.
How big are the intake valves on a Toyota 1KZ-T?
Intake valves are 42.5 mm (1.6732 in) in diameter, and the exhaust valves are 37.0 mm (1.4567 in). The Toyota 1KZ-T engine does not have hydraulic lifters, so special shims are used to adjust the valve clearance. Shims are available in 17 sizes from 2.50 mm (0.0984 in) to 3.30 mm (0.1299 in), in steps of 0.05 mm (0.0020 in). ATTENTION!
