How can broken valve springs and defective valve stem oil seals be replaced without removing the cylinder head on 4 cylinder Nissan Altima?

Valve springs, in particular, those which are broken, and valve stem seals, which are faulty, can be replaced during the course of avoiding the removal of the cylinder head; this requires generally two special tools and a source of compressed air. Waiting for the cylinder head on a stable bench, utilize the big and large clamp type of valve spring compressor and adapter where the bottom part of the tool should be resting beneath the working valve and to compress accordingly until the keepers can be easily removed with the help of magnet or small pliers. Extract the valve spring along with the retainer, to eliminate it, undo the old valve stem oil seal using pliers. Run the valve stem in the guide and using your fingers see whether it wobbles; this is an indication that the valve is bent. Rock the valve back and forth in the guide and look for binding; if there is binding then the valve maybe bent or the guide may be damaged and this means further procedures of cylinder head repair. Apply a coat of engine oil on the valve stem and then fasten the valve spool into the cylinder head, placing a piece of plastic container seal guard on the valve stem to avoid tearing of the new seal. If there is no seal protector, wind the cellulose tape around the valve stem of the faucet . With the multi-purpose grease provided, immerse the new seal and push it downwards over the valve stem; the protector or tape should be withdrawn when the seal hits the guide. Place the new seal into the deep socket appropriate for the diameter and gently tap it down to the top of the valve guide, then put the spring into proper place over the valve with the retainer. Next, co sam Main spring of the valve and its retainer; use the keepers to fit the spring in the grooves and if it is needed a small amount of the grease must be applied in order for the keepers to be stayed in place and properly fixed; the keepers should be inserted with the needle-nose pliers. Release pressure with the use of spring tool while confirming that the keepers are in place. Replace the lifters and camshafts, and finish the procedure in a sequence that is the reversal of that implemented during removal. Switch on the engine and observe its performance and the extent of oil leakage and strange noises originating from the region of the valve cover.

Nissan Altima Valve Stem Oil Seal

The Nissan Altima Valve Stem Oil Seal prevents engine oil from entering the valve stems and burning in the cylinders to maintain power and reduce smoke. Each Valve Stem Oil Seal sits atop the valve guide and meters oil to ensure the stem is always coated in oil. Further, the excess oil is kept from entering the combustion chamber, which helps to maintain steady compression and cleaner emissions. Over the years, Altima has depended on an overhead cam valvetrain. In this design, cam lobes press directly or through followers on the valves. Whether single or dual cams, the Valve Stem Oil Seal performs the same gatekeeping task. Due to regularly being subjected to heat and motion, the engine causes the oil to harden with mileage. As a result of this hardening, the engine may produce bluish exhaust and oil consumption may rise. Both are good indicators that the oil requires replacement. The Valve Stem Oil Seal is unlike valve springs or rocker arms, which can fail all at once due to loss of pressure or lash. On the other hand, the Valve Stem Oil Seal simply loses elasticity. This is a slow process, however, which careful Nissan owners can detect long before it becomes an issue. Early detection can help keep the Altima performing well. Installing a genuine Nissan seal will promptly restore proper oil control.
