Dipper pan, oil level question, speedster project.

Post by dobro1956 » Thu Apr 25, 2019 11:01 pm

I am in the process of converting the oil pan (crankcase) to install on the speedster project. I am just checking to see if Im thinking right. Is the stock oil level of the dipper pan the top surface of the flange that the inspection cover horse shoes sits on. It seems like the oil level would not be affected by the horse shoes since the oil just runs around them to get back to the crankcase sump. I am planning on adding a dam to the rear of the dipper pan area to raise the oil level 1/4 inch above the stock level. Then I will install three or maybe four pipe nipples with a 1/4 inch ID, into the dipper pan flat areas to drain oil into a Sherman deep sump oil pan installed below the stock dipper pan. I will set the drain nipples to be 1/8 inch above the stock oil pan level.

This is all based on just using the stock oil funnel to the front of the engine. More than likely I will also have a high volume oil line similar to the Texas T Parts product, to feed extra oil to the dipper pan.

So in theory I am raising the stock oil level 1/8 of an inch before the oil starts to drain into the Sherman pan, and using the other 1/8 of an inch to feed the Sherman oil pan .. if I use a 1/4 inch high dam .. ???

What is the accepted amount to raise the dipper pan oil level with out oil fouling. ???

Thanks ...

Your plan is pretty much spot on. Be aware that heat in your dam area will tend to distort the pan, but your pan jig will fix that.

Thanks Dan... A year or more ago, when I bought the Sherman deep sump pan. Herm also answered my question, but I just forgot. Its hell getting old. :)
He used one 1/2 inch pipe to feed the deep sump pan below the dipper pan, instead of three or four smaller pipe nipples. He also thought that 1/2 inch deeper oil level would be the max before oil fouling would be a problem. With you and Herm saying Im headed in the right direction ...

Its off to the shop I go .... to see if I still know how to braze weld ..........
