Collapsed lifter?

Collapsed lifter?
I have a loud ticking coming from my driver side valve cover. 95% sure it isnt a header gasket leak b/c I just changed those and threw on ARP bolts which have not loosened at all. I was told it could be a fuel injector or a collapsed lifter.
If it is a collapsed lifter, can I drive it without it doing any harm to my car? How about on the dyno or at the track? I plan on tracking it sunday.
The wierd part is that the noise started in the summer when I had the UD pulleys installed. The pulleys were installed fine, threw some codes so I pulled the battery to reset the PCM and when I reconnected it and started it up, the noise appeared. Coincidence?

my friend built a bad *** ford 391 for his 67 grad tourino (i think 67)
anyway, they sent him pushrods that were slightly longer than the correct size. collapsed a lifter, got metal in the oil, wore the bearings low oil pressue.
change the oil
check for metal is a good start
you can also take the valve covers off- and let it idle
if its really collapsed, one rocker wont be doing a whole lot of moving

WRT the tick,
A little valvetrain noise is not something to get too worked up about. Check lift at the rocker and check the preload adjustment.

I am going to change the oil tomorrow at lunch hopefully. I need to get the thing emmissions test too Saturday morning.
Will I need a new gasket after I pull of the valve cover? I will do it at work tomorrow. It doesnt look all that time consuming. How long would you suspect?
New valvetrain and such is coming in the summer once I have the money.
I am going to check the header gaskets also. Who knows, I might have a warped flange and it blew again. That would make things easier. I think I would have saw some smoke coming from there when I did the seafoam Sunday though.
