Reply to "Dreaded distributor Pin"

Well it seems to me that there needs to be a "fuseable link" in the system?

The cost of a roll pin is by far the cheapest fuse to have?



Seems to be a matter of choice? A twisted stock drive shaft would be an indication of a very serious oil pump issue and I'd rather shear the pin.

What's the point of having a drive shaft that turns itself into a pretzel? It still needs to be replaced.


The issue here really is the pin shearing under "normal" use or was there additional issues with the pump drive system?

That's a debate that can go on forever with no resolution.



Reinforce the pin. Double pin with Loctite on it is a "reasonable" solution. Even if the alloy of the steel in the pin is incorrect, a double pin should take care of that.


As far as running the pressure down to 10 psi, I don't feel comfortable with that. I'd rather over oil than under oil.

My oil idiot light is set at 10ish as well. A high volume pump that shows 80 psi isn't a ridiculous strain on the system. It drops to 35psi hot at idle. That's still within the safe limits.


There is absolutely no control with the aftermarket as to the sourcing of components. The drive gear seems to be a "person of interest" in the case.

Aftermarket companies I suspect are buying them in bulk from "off shore" companies and I suspect is the largest single factor with the issue.
