Tempted on removing, cleaning and reinstalling hitachi original distributor on my 240z

It's not leaking? Why do you want to remove it?

My thoughts exactly.....”If it ain’t broke, don’t break it!”

Yes, exactly!!

 Unanimous. Find something else to work on unless you're like me and your obsessive curiosity won't let you rest until you know what went wrong the first time around. In that case, grab a service manual, and maybe a timing light and have another go at it. You only need to remove the two lower bolts to remove the dist. If you loosen the upper one you'll screw with the ignition timing. BTW, the dist. may be original but it's been upgraded. It no longer has points or a condenser .

Can you point out which screw must i remove only on order to avoid screwing up the timing and as consequence able to crank the engine once installed.

He wants to replace the o-ring, which requires removing the adjustment screw.

If people weren't working on their cars the site would probably die.

I have some fun for us all though.  I'm not positive but I think that somebody has installed the plate on the bottom of the distributor backwards or sideways.  Not even sure how the distributor is clamped down to avoid rotation when the engine is running.  Might explain many past problems.

Where is the screw?

This is very true in a broad sense, but it is easier for some people to get out of the hole than others

However you look at it, he does have a new different problem that he should fix.  If his distributor is not locked own, his timing is going to walk eventually.

Beside that, this a proper, separate, thread.  Nobody has to get involved if they don't want to.  Just saying, it's his own hole, let him dig.

I might be wrong about his problem though.  In that picture I expected to see the locking screw.  Maybe the 240's have it on the other side, and adjustment marks on the side I see.

Should be where the red arrow points.

Here's a 280Z.  So, I had it backward.

Mark the distributor here, remove the screw on the other side, pull the distributor straight up.

Not the screw pointing upward, but the screw you can see from the top.
