How to remove and install the intake valve and valve spring on Mazda B2000?

In order to replace or replace the cylinder head, the cylinder head must be removed followed by the removal of the rocker shaft assembly and camshaft (in certain models). Wipe off the combustion chambers with a stiff wire brush and scraper without scratching the cylinder head surface. Install a valve spring compressor, loosen the valve spring retainer locks and springs. Make a valve set-up board to record the initial positions of the valves and its components that were originally installed. Dispose of the valve seals taking a note of the umbrella-type seal positions. Clean the valves and cylinder head mating surface and do not use metallic scraper. Clean the valve guides with a valve guide cleaner and then put each valve into one of the ports. Check valve stems against specifications using a micrometer and measure valve guide-to-stem clearance using a dial indicator. Valve removal can be done by blocking the head with a socket to break the deposits of varnish, and maintaining parts that have been removed. Wipe down the valve ports and seats and ensure that carbon deposits are wiped off. Check the head of the cylinder head and grease the valve stem-to-guide clearance. Fix damaged valve guides, and machine valve faces and seats to specification. Lap the valves and seats, and then affix the seats. To reface a valve, resurface valve with a valve grinder to specification paying attention to margin widths. Upon machining, place the valves with lubricated stems, then valve springs, retainers, and seals should be placed in proper order. Lastly, tap all the valve spring retainers to fix the keepers.

Can broken Valve Spring, Valve Spring Retainer and Valve Stem Oil Seal be replaced without removing the cylinder head on Mazda Protege?

Replacement of broken valve springs and faulty valve stem seals can be done without the necessity to remove the cylinder head, and usually necessitates two special tools and a source of compressed air. In case of non availability of compressed air a piece of nylon rope may be employed to ensure the valves do not fall into the cylinder. Start by taking the camshaft(s) and valve lifters off the faulty valves, and store the lifters in the correct sequence so to re-fit. Take off spark plug of the affected cylinder and in case all the valve stem seals are to be replaced remove all spark plugs. Turn the crankshaft (referred to as crankshaft revolution) until the piston in the damaged cylinder reaches Top Dead Center during the compression stroke, and then move on to the next cylinder in the firing order. Insert an adapter into the spark plug hole and fit an air hose with a compressed air source and spray the compressed air to make the valves stay put. When it is nylon rope, the piston should be positioned at about 45 degrees before TDC, and the rope inserted into the combustion chamber and turned until slight resistance is felt. Insert stuffy shop rags in any holes on the cylinder head to ensure that parts do not fall in the engine and then compress the spring with a valve spring compressor to take out the keepers. Installation: Take out the spring retainer and valve spring with a mark on the upper end of the valve spring. Measure the depth till the upper side of the valve stem oil seal and strip. Tape or wrap a rubber band round the top of the valve stem to ensure that the stem does not fall off and then remove the air pressure. Check the valve spring and stem, and there must be none bound in the guide. Repeat air pressure to hold the valve in the closed position, and lubricate the value stem, and place a new oil seal, taking depth of installed as needed. Install the spring on the top of the valve making sure that it is placed properly and the valve spring retainer goes on and the spring is compressed to install the keepers. Take the spring tool off the pressure, making sure that the keepers are in place and the air hose is disconnected and the adapter removed. Lastly, install the camshaft(s) and the other components in the reverse order and start the engine to determine the presence of oil leakages or abnormal noises.
