Ford EJ7Z-6505-A Exhaust Valve

Disconnect the cable from the negative battery terminal. Remove the spark plugs, then take off the valve cover. Loosen the right front wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands before removing the wheel and the fender splash shield. Using a wrench or socket on the crankshaft pulley bolt, rotate the crankshaft clockwise and check each lifter when its camshaft lobe is straight up, ensuring that the measurement is between the base circle of the camshaft lobe and the top of the lifter. Use feeler gauges to measure the clearances, ensuring a slight drag is felt when sliding the gauge between the lifter and the camshaft if the clearance is correct. Check the clearance between each camshaft lobe and the lifter it operates, keeping careful notes of the measurements recorded for each lifter. If some measurements fall outside the recommended clearances, the camshafts must be removed along with the out-of-spec lifters. New lifters are available with various thicknesses to correct the valve clearances, marked with a thickness number that only includes the digits after the decimal point. To determine the desired thickness for new lifters, add the thickness of the original lifter to the measured clearance, then subtract the midrange figure for ideal clearance to find the proper lifter thickness to order, noting that not every thickness is available. For installation of the camshafts, once the camshafts and timing chain have been installed, recheck the valve clearances. The remainder of the installation follows the reverse order of removal, and after running the engine, check for oil leaks.

First, pull the battery cable away from the negative terminal; remove all of the spark plugs and the valve cover. Some of the challenges are Loosen the right front wheel lug nuts-lift the front of the vehicle-support the vehicle secured on jack stands-remove the right front wheel and the fender splash shield. On another engine, with a wrench or socket on the crankshaft pulley bolt, turn the crankshaft clockwise and check each lifter when its camshaft lobe is directly vertical, it's preferred that the distance is between cam base circle and top of the lifter. The correct clearances are obtained by the use of feeler gauges with a very slight drag being felt when sliding the gauge between the lifter and camshaft. A measurement check should be carried between the clearance of each of the camshaft lobe with the appropriate lifter and document all the readings. In the event that any of the anterior mentioned clearances prove to be out of standard, both the camshafts and lifters that are out of spec must be withdrawn. New lifters are available in various thicknesses, it is stamped with a thickness number; only the numbers after the decimal point are important. To decide the lifters' thickness for a new set, sum together the thickness of an original lifter and the measured clearance, and then subtract the midrange figure for the ideal clearance to arrive at the proper thickness of the lifter to order, choosing the closest available thickness. After the camshafts and timing chain have been fitted, it is essential to again inspect the valve clearances; after that, the work is done in reverse order. Last but not least of the oil change procedures is to start the engine and inspect it for oil loss.
