Nissan 240SX Intake Valve
The Intake Valve of a Nissan 240SX allows air and fuel to enter each cylinder before firmly closing so that compression builds. The Intake Valve is located on the cylinder head and is opened and closed by the camshaft lobe through the valvetrain. The valvetrain can include lifters, pushrods, rocker arms, or bucket-type followers that transmit motion from the cam lobe to the valve stem. The mixture enters when the Intake Valve opens after the power stroke. Spent gases are released by the separate exhaust valve. The purpose of correct spring pressure is to keep the Intake Valve seated during a stroke. For a stock engine, the proper pressure when closed is approximately 70 to 90 pounds and when open is about 200 pounds. Too little spring pressure will cause misfire when the engine speed rises. In addition, Intake Valve float will occur if the spring pressure is too little as well. In a Nissan 240SX engine, overheating or insufficient spring pressure can cause the valve to burn, warp, or stick open, resulting in power loss. Regular attention to lash clearance and spring strength assists the Nissan 240SX in holding a good combustion seal and prevents the Nissan 240SX from damaging costly mechanical parts. The Intake Valve is important in all 240SX applications.

Nissan 240SX Intake Valve Parts Questions & Experts Answers
- Q: How to remove, inspect, and reinstall the Exhaust Valve, Intake Valve, and Valve Stem Oil Seal after removing the cylinder head on Nissan 240sx?A:Important steps are involved in the removal of Cylinder Head and valve servicing. This is where a valve spring compressor comes in handy. Put the cylinder head on the workbench, stabilize the valve head by using the instrument to press down on it and compressing the spring by flipping the screw around against the retainer and the valve head. Once exposed, they can be removed with a magnet. Turn off the screw so that retaining springs can be released, take out compressors then draw out valves. Take away spring seats of valve as well as valve seals. The holes on a piece of wood or cardboard should be labeled according to each corresponding valve in order to maintain order while making sure that valves and their parts remain together for reassembly. Lubricate each valve stem, lap valves then fit them with new stem seals before compressing retainers and springs enough for keeper groove exposure. Make sure both retainers fit correctly when inserting keepers hence closing up compressor again after installation. Hit lightly on stems of these valves to secure retainers and keepers for them not to become loose easily. Last but not least, adjust valves. Valve inspection includes cleaning stem, face or head of a valve; then measuring using dial indicators as well as micrometers. Go to a machine shop if these tools are not available since this service may be provided there too. Average inside diameters of valve guides and different diameters of both intake/exhaust stems must be measured directly or subtracted into determining stem-to-guide clearance values against specifications given in manual for most engines. In case grinding operations are necessary, check tips' pitting/wear signs within permissible limits only however consider also reviewing stem-to-guide clearance during re-assembly such as when changing guides or fitting large-sized valves. Finally clean guide plus stem for one's checking it by rocking its indication.
