All I need now is a harmonic balancer puller and I'll be ready to pull the timing cover and take a look. Does anyone make a puller that you do not have to wedge or block something in the flywheel/flexplate?

I assume you are having a problem with the engine turning over while trying to turn the screw on the puller to pull the balancer off?
You could pull a plug and use a piston stop to block the rotation. My puller has a square ear on one side for an additional wrench to keep it from turning. |

Just go and buy a $10.00 Harbor Freight Harmonic balancer puller. Do not use the the 3 jaw type.
A Cloyes set is better than most so the oil passage to the distributor gear should be OK. Here is a picture of the oil passage from the cam through the timing gear. Here is the Cloyes and a cam that I had laying around. I ground off a drill bit to use as a pointer and stick it on the cam hole. As you can see, Cloyes on this particular cam is ok. All parts have to be checked no mater what the brand name is. |

X2. I popped a 343 blanacer ring right off the hub with a claw type puller. Admittedly the balancer was pretty worn but it was wasted after the outer ring popped off. Any parts store has a decent puller for around $30

Got it out tonight, Yeah it's toast! Rented a balancer puller from the parts store. The timing cover appears to be OE. The pins were still in the block so I'm feeling pretty good about everything. Hopefully it was just a bad gear!?

SC397.
That litttle milled pocket on the back of the gear was rotated so much on my cloyes set that the path for oil was eclipsed about 90-percent. They must have made mine at 8:01-AM after a 3 day weekend.

Dane.
I hope you drop the pan and give everything a good clean up. Mine had lots of crud in it. None of it got part the filter though.

I don't have any experience in disassembling corroded aluminum components (distributors). Any recommendations as to how to do it? A little heat, lots of Kroil, both, ?????

Yeah, I've bought Cloyes since about 1970.
It's possible that it was the cam and how it indexed to the gear and not the gear itself. But I had no way to compare it to other parts at the time. I just milled the cavity to fit the situation.
I also found several Engle cams that had the "snout" much longer than stock and the front screw was nearly touching the back of the water pump cavity in the timing cover. So if the cam walks forward a tiny bit, the star-points on the screw dig into the aluminum and the screw jacks its way out and blows a hole into the water pump.
Scary stuff huh? So I started smoothing the star points off the bolt - thinner washer - checking the clearance with play-dough and adopting an anti-walk plate for the cam henceforth.
