[DeTomaso] lifter noise

[JDeRyke at aol.com]

I would put on some old clothes, then pull that rocker cover where te noise 
seems to originate and start the engine. At idle there will still be some 
oil mist coming out of the pushrod ends, but that's how I adjust valves. 
You'll have about 3 minutes before things get too hot and the oil starts smoking 
on the exhausts, so work fast. While the thing is idling, you can 
(CAREFULLY) touch each of the rockers in turn with a finger to listen for a change in 
the clicking sound. This will isolate the cylinder and narrow your 
possibilities. There's nothing in there that will reach out and grab your finger- 
just don't reach in between things.... 
Of course, if there are loose pieces laying inside the head, you don't need 
to go thru this exercise. Good luck- J DeRyke
