[alfa] Piston Slap

[John Cecil <jcecil@xxxxxxx>]

Fellow and esteemed Digesti-

I have a '87 Spider Veloce which has been diagnosed as having piston slap in
the #1 cylinder. The engine has only about 25,000 mi., It uses almost no
oil, has normal power but makes a tapping noise which goes away when the #1
plug is removed. My opinion is that the liner is abnormally worn, but I have
no idea why as the engine has never overheated nor run with low oil (Mobil 1
15W50). Oil pressure is over 60psi at 2500rpm and registers even when hot at
idle (does not read zero, but actual value is hard to tell from the gage).
Also, there is no smoke at all from the exhaust.  My question is this: Is
there any potential for catastrophic failure if I just go ahead and drive it
and ignore the noise? Also, has any one ever heard of a problem like this on
such a low milage engine?
