[Es2] Good news and bad news...

[Miller, Chris]

I don't know about rotating the engine; haven't thought about it.
The engine goes through 4 cycles:

TDC then
  intake
to BDC
  compression
to TDC then
  power
to BDC
  exhaust
back to TDC and starting over

No, the head hasn't been shaved. The crank bolt is tight and the keyway is
intact. So if I pull the T-belt off, is there any way I can rotate the cams
independently of the crank to get the distributor in the correct position
without damaging the valves or pistons due to interference? ie, is there a
crank position in which none of the pistons are at the top of their travel?
The reason I ask is that this would be a lot easier to do than removing the
distributor.
The other thing I'm pondering is, if in fact the distributor rotor is out by
180 degrees, then on the next revolution of the engine to TDC, wouldn't the
rotor then be lined up properly? If so, then it would seem impossible that
the rotor could be "out" by 180 degrees.

Yes, I think the rotor could be 180 degrees out, and yes, this will
matter...
Also make sure the crank bolt is tight, and keyway is intact... did you
shave the head down at all?  This might also alter timing a little bit.

Hi Chris,

The distributor is the original and was never removed from the head. I did
however replace the cap and rotor. The rotor has the wide end on it. I
purchased it from Rod TPC who noted that it was different, but said it
should work. Is the rotor with the narrow head still available? Has anyone
tried the new style rotor and had this problem?
The other theory I was thinking about last night is that maybe the
distributor is 180 degrees out relative to the crank shaft. The
distributor-to-cam shaft gear ratio is 2:1 correct? If so, this means that
the dist turns one full rev. for every two of the cam shaft. Because the
head was removed and the cams were turned independently of the crank, would
it not be possible that the head was reinstalled with both the cams and
crank at TDC, but the dist. at 180 degrees (half a rotation) out? Or does
that even matter?

Ben

  Hi Ben.
  Is this a new distributor?  I'd start with the alignment first.
  Assuming you've moved it around, put the engine to TDC, pull the dist.
cap, and look to see if the rotor points at the scribe mark on the side of
the dist. body (center of rotor to line).  Think it should be the number 1
plug wire too.
