Re: Tapping from engine when driving
There are many causes to a tapping noise although the original tapping was probably a lifter that once the engine oil pressure increased and the oil got hotter it went away. The issue you have not is probably a failed or bad lifter. You may have to replace the lifters and adjust the rockers to get the noise to go away. It isn't a hard job to do but you will need some time since it will take about 8 hours. And since you will be removing the lower intake manifold this will be a good time to change the gaskets.
If you remove the valve covers you may be able to find the bad lifter since the push rod may be loose or the valve not moving to full compression on the valve spring when the engine is rotated. Either way you will probably need to replace at least that particular lifter.
Good Luck!
