Q: How to remove and install valve lifters,Camshaft Bearing and pushrods in Cadillac ElDorado and Fleetwood?
A: For 4.5L and 4.9L engines, maintain valve lifter and pushrod order during removal and installation. Remove the intake manifold and valve covers to access lifters. "O" markings indicate oversize lifters. Reinstall associated components. For the 4.6L engine, start by removing the camshaft cover. Next, remove camshafts and lifters, storing lifters face-down for oil retention. Return lifters to original bores during installation, followed by camshafts and cover.
