Engine Noise
#11
It's a long winter, if you have access to the car, I would have a look at the valve train on that side and get that noise taken care of. The last thing you want is to miss a few events next year with a repair that lays you up for a week or two.
On the crank shaft end play, not sure about that. I have only checked that during engine assembly. On my old race engines. It is basically the gap on the crank shaft thrust bearings. I am not sure how that effects oil, but if Art say so, I would believe him.
Cheers,

As for the crank shaft end play, what you describe is what Art described, but not sure how to check it with the motor in the car..

Not sure if it can be done in car or not. Normally it is done with a dial indicator on the end of the crank shaft so it measures front to back motion. Then pry the crankshaft all the way back, then pry all the way forward . The difference as measured with the dial indicator is the end play. The trick is where to pry from. Normally the pry bar would be on the block somewhere.
No sure what the spec is on end play, some one may hoist in with that.

This method over many years and recommend that you do not assume the trouble is a certain part, as a problem in one area will often show up as a symptom somewhere else. An example is carb malfunctions are often incorrectly assumed to be governor problems.

Spec for the crankshaft endplay 2001 mustang GT 4.6 sohc is 0.003-0.015", but you are right that it will be hard to check with the engine in the vehicle. Noise could be coming from a lifter, stretched timing chain, or any number of engine components, so pin pointing the noise is a must before disassembly and measuring all components and comparing to specs.
