[DeTomaso] Top End Noise

[Charles McCall]

A bent pushrod would do that, as would other things. I just happen to have
personal experience with bent pushrods..

Substituting a bent pushrod for a straight one will only result in more bent
pushrods until you find what the root cause is.. In my case this happened
right after a rebuild and a number of errors were made during the rebuild.
If your engine has been running for a while then this may not apply..

I think I found the source of the noise coming from my valve train.  On the
advice of several observers at Cars & Coffee Bonita, CA, I drove my Pantera
home and took my Genesis Coupe on today's fun run through the Southern San
Diego mountains.  Here's a short video of what may have been causing all the
racket (loud tapping).  

The noise just started yesterday on my way home.  The engine recently
suffered a brief oil starvation situation when it ran low on oil in the
crankcase.  The oil shortage was addressed promptly, but after about another
hour of driving, the noise started. 

Attached is a brief video of of the #3 intake rocker.  What do you think?
