If you think it is the distributor, pull it and check the o-ring. I pulled
mine recently and it was as flat as a pancake. No rattle - but, it
definitely needed to be replaced.
Pulling the distributor is easy. Just set the motor at TDC; make sure the
rotor button is pointing at the connection to the wiring harness (if 180°
off, rotate crankshaft one more time); make sure the mark between the
distributor and head are aligned; remove the bolt and slide the distributor
out.
Actually, you shouldn't really even have to pull the distributor. Just grab
it and see if you can wiggle it back and forth and make it rattle. I kind
of doubt if it is the distributor, anyway.
I assume you are talking about the 3VZ-E because you said 'belt' and the
22R-E has a chain. If so, there are two idler bearings that the timing belt
runs over on that motor. The do go bad eventually - I suppose they could
rattle if the bearings have fallen out or the tension spring could have
broken and the lever it attaches to could be flapping around. Can't think
of anything else in there that might be banging around but it sounds like
something that needs to be checked out to me.

Distributor Problems....
Hi i have a 4WD 88 toyota pickup. I am hearing a rattling sound from my
dirtibutor (at least its close to there).
It makes a constant rattling sound as soon as i start my truck. I can only
hear it when im outside my truck. But when im drving i can hear it when i
accelerate or maintaining constant speed. Not when i deccelaerating or am in
neutral.
I thinkits my distributor or possibly one of my belts(timing maybe?) I
replaced my distr. cap and rotor and still no fix. A friend doesnt think its
my distributor cuz he took my cap off and had me crank it once. HE said that
the distributor looked fine.
So im not sure? Any tips or tricks i use to help me find the source of the
problem?

Sounds to me like you have the 22R or RE motor and your timing chain is worn
out. You will start hearing a dragging noise in the timing cover from the
chain which will increase in noise with the speed of the engine. What is
actually happening is either the chain is chewing up the chain guide on the
driver's side (if you're lucky) or the chain guide on the driver's side of
the engine has broken and the chain is eating the timing cover. The
easiest way to tell if you have a slack timing chain is to take the
distributor cap off the distributor, put a socket wrench on the crankshaft
pulley (probably 19mm) and turn the engine clockwise (facing the front of
the engine). After you see the distributor move a fair amount (say 90
degrees), stop, reverse your ratchet, and crank the engine
counter-clockwise. If you are able to turn the crankshaft a good amount
before the distributor turns, then your chain is worn out. The later 22R
motors had a single-row timing chain which should be replaced IMHO after no
more than 90,000 miles. I've seen them with 200,000 miles on them, but also
with bent valves from the slack chain.
Does your truck backfire in the exhaust when you let off the gas while
coasting? That's another sign of a worn chain.
