[DeTomaso] Pandora question

Sat Nov 27 12:19:19 EST 2010

The how-to video is pretty slick, complete with a very British sounding
background music.  If it's not a clearance issue to the No. 1 cyl, on a
Pantera, this should work for us, yes?

I came across this pneumatic kit to find TDC:

Anyone know who sells something like this?

Darn--and I thought I finally had something figured out!

Stephan
had tried to tell me about the engine rotation and its relation to the rotor
position, but I didn't quite get it, I guess.

I checked the timing at about 11,000 rpm (basically at idle), and I clamped
the vacuum advance hose while I checked.  At that point it was at the black
mark, 38 degrees.

The entire
motor is new, except the block (Cleveland) which was sonic tested and bored
out, so although slippage was suggested, those who know the engine build are
doubtful.

I marked zero top dead center on the access hole on the ZF, just in case, so
if the damper slips I'll be able to tell.

I
just can't figure out why is starts and runs so great when the timing mark
seems so far off.  Plus, there is a black magic marker mark on the damper at
38 degrees BTDC, which is where it runs well, so I think this issue might
have been this way since the new engine was built about 4 or
5 thousand miles ago.

I'll do more research and keep you all posted.

Thanks again for all your help,

Chris
