Amateur question here
So, does a late 90's or whatever 351 have an oil slinger washer between the timing gear and harmonic balancer, inside the timing cover to keep from flooding the seal?
I've looked for one on Summit and ebay thinking if there was one, I would stumble across it, but I haven't seen one for a ate model windsor. It's been a while since I've actually rebuilt an engine, and this one is from scratch, so I don't have an example of all of the little bits one could overlook. For than matter, most of my experience is with small block mopars. Thanks |
No slinger on small block Fords.

All Windsor engines come from the factory with that washer. It's not an oil slinger. The goal is to keep pressurized oil off of the seal, and helps prevent leaks.
I have never found one in any catalog. Not even sure you could get it from the Ford dealer. I have only seen one a couple of times over the years. Only when I'm taking apart an original factory assembly that no one has touched before. This is a picture of an old Dodge motor. Same concept. https://i.imgur.com/ySOS2mg.jpg Without it, you can sometimes run in to spacing problems at the front of the balancer. |
Thanks
I picked up the shortblock today and the builder also said no one uses them. Seals are so much better now than they were 50 years ago it;s not a problem. As for spacing, I'll be fabbing brackets and machining down the pulley spaced to fit a trigger wheel in anyway. I'll deal with that as I get to it. |
fuel pump
Hi,
That is a mechanical fuel pump concentric on a small block Ford. P:MECOOL:erry |

What the OP was asking about is the thin washer looking SRT on the front of the crank snout. |

Obviously, proper spacing is pretty important. But, here's a point you don't hear much about. Once everything is bolted in tight, take the crank snout bolt back out. Make sure the crank snout is below the surface of balancer, where the washer sits on. If the crank snout is even with or slightly above that surface, it will be impossible to actually tighten the balancer down. And then bad things will happen. Guess how I know that? ;) It's pretty easy to make a big washer of the proper thickness to fix that problem. |

The purpose is to keep oil SPLASH away from the seal. There is no oil PRESSURE aimed anywhere near the seal. Many engines have this, and if you have the option, run one. |
