Oil slinger needed

[jayb]

 Not like you can just pop the balancer off and replace the seal.  That would have been a smart move FORD! 

You can do that on an FE, as long as it uses the FE Power timing cover and the 351C front seal.  The crank sleeve has to be modified though, to extend the sealing surface farther forward.  Installing the seal from the front moves it's position forward a bit on the crank.

Do you make a sleeve yourself for that reason Jay

"You can do that on an FE, as long as it uses the FE Power timing cover "
That is because you thought ahead Mr. Jay B!  I wondered if you were going to catch that HAHA.

You should have added a sales pitch for "low price of XXX save your frustration".....can't miss a sales plug opp!

Anyway, it is a well designed, good fit/finish product. 2 Thumbs up, I just have not bit the bullet on one.

Is it this video?

Brent, I don`t know about the video, but in Jays book, it shows a clear sight tube on the side of a steel oil pan, showing how there was more oil in the pan with the rocker drip trays. The photos are on pages 233-234 of Jays book.

As for the sudden drop of oil level once the throttle is closed on the dyno, any theory on why that happens? I could see it on a rear sump under braking, or a front sump on acceleration, as the oil runs away from the somp, but on the dyno, that situation doesn`t exist.

I don't really have a theory about why it happens.  It's odd though because I see it on every engine I dyno.  It's at full song, then when the throttle is shut and the engine comes back to idle, the oil pressure will drop 10-15 psi below what it normally was at idle, then pick right back up.   It's not an oil level issue, because even on that video, you can see that the pickup would have been well covered.   

Maybe it's a bypass issue?  The pump has the bypass open at the top of the pull, then when you shut the throttle down, it's closing the bypass and something is happening there?  Maybe we can get Bill Conley to try and recreate the issue on his pump dyno.

I don't have Jay's book, but I did tell him I'd take one on his next shipment. 

The reason I've never duplicated his showings is because I don't use HV pumps with factory pans.  They either get SV pumps or B pumps.  The B pumps work extremely well in most engines (and consume less hp, as verified by Bill Conley's pump dyno).   I had one in my 352 with a stock pan, pulling to 7000 rpm, and it carried the oil pressure all the way through the top of the pull, which indicated the pickup was not being uncovered.

It certainly would be interesting to find out what causes the drop in oil pressure. On my drag car, I have never noticed this, and being a stick, I typically put the trans in neutral as soon as I cross the finish line, and lift off the throttle, so the engine is going from WOT at over 6000 RPM, and then right  back to idle, and unless I get hard on the brakes,(rear sump oil pan), the oil pressure never seems to drop. I have not really ever had any bearing issues, but seeing that video makes me think it would be a good idea to install the Moroso Accusump oil accumulator that I have had sitting on the shelf for several years.

An accumulator certainly couldn't hurt. 

I will say that the oil pressure change happens pretty quickly and recovers quickly.  I dyno'd the 352 again yesterday and watched for this as we had just talked about it.  It recovers within about a second.
