Dry Sump Pump and Oil Line Routing

[DreamsOfA47]

Hello, all! I come hoping those of you with much more knowledge and experience can help me figure out the dry sump set up on my twin cam engine. I purchased an engine from Grumblebuns (the Europa Wizard himself) that came out of a TC autocross car. It came equipped with a dry sump set up, but instead of a 5-port Titan type pump that I’m used to seeing and that is in the Dave Bean catalogue, the pump is a 4-port design. The 5th port is actually a -12 fitting tapped into the upper right (closest to firewall) bolt hole in the driver’s side engine mount boss. Does anyone have any info on what ports in the pump and on the block do what?

I’ve tried my best to do research on the internet before bothering y’all but I can’t seem to find an answer. The most I can determine is that it may be a Formula Ford, mid-engine type arrangement as opposed to the arrangement I see often on Elans. This engine is going in my S2 Elan race car but seeing as its from a Europa I figured y’all may have more experience.

Here’s the set-up

Whew! I'm sure glad I have 4 monitors!

I'm not familiar with your pump but I think all the dry sump pumps that replace the stock pumps on a Kent block are probably the same.

I've posted a picture of how my pump is plumbed (as setup by Dave Bean himself!). One of your hoses is in the way so I can't tell if you have the same port on your block that Dave labeled "pressure in from filter" that I do (see picture). If so, you can plug the one on the driver's side and use this one. I'm not positive but I highly suspect that the port on the pump that Dave plugged (under the dizzy) would otherwise be pressure into the engine (i.e. the same thing as "pressure in from filter" but maybe more difficult to plumb or not as efficient... But it doesn't look like you have that port on your pump.

If my picture doesn't help you, you might want to give Ken Gray at Dave Bean a call. He might be able to help. If not, your pump is obviously not a Pace pump and Pace has been acquired by Neil Brown Engineering anyway but they may also be able to help since the still support the old Pace pumps (https://nbe.co.uk/).

A warning so you don't make the same mistake I did. Your oil tank needs to be low so the bottom of your tank would be near the bottom of the engine. I wanted to keep my trunk tray and also route my exhaust the way it was originally and my shift linkage (and oil cooler are under the trunk tray on the driver's side. I put my tank in the only place left: behind the carbs and just in front of the trunk tray. It is too high and the oil siphons out of the tank in about a week. Our own Vegantune mounted his in front of the front trunk and it works fine for him though he had to get a little clever so allow draining the tank while sealing the area for the radiator.

Hi, BDA! There isn’t a port on my engine where Dave has labeled “pressure in from filter,” and I don’t have the port he’s labeled as “plugged.” Well considering that he has it labeled plugged I should be able to get away without it! I’m still quite confused as to what the exhaust side fitting is for!

Comparing mine to yours, the scavenge P/U is self explanatory, the plugged port is non-existent, my pump has an outlet in the “pressure out to filter” and a “scavenge to top of tank.” I guess the tapped fitting has to be pressure return from filter 

Does that make sense to you?

It doesn't make any sense to me that the "pressure in" port would be on the opposite side of the engine (and under the exhaust) from the oil pump! I'd give Ken at Dave Bean a call to see if he can make any sense out of it for you.

You raise a very interesting point. That wouldn’t make much sense! I found this picture of the oil passages of our motors and that fitting iOS on the pressure side! I’ll definitely have to give Ken a call and maybe take a trip to Bill Schlossnagel’s shop too see what he thinks.

I may have an update for anyone casually following this thread: After some internet sleuthing and a whole lot of forum reading I may have been able to determine what that fitting is for! I’ve discovered that the Formula Ford 1600 guys use 4- port pumps pretty often and the only difference between the 4-port and 5-port Titan style pumps is the lack of the upper right port, labeled in the attached pic “pressure feed from oil filter to engine.” The FF1600 guys usually tap a return fitting into the front of the motor after removing the front oil return gallery plug. I’ve realized that the oil return gallery is directly under the location of the AN fitting tapped into the side of my block as shown in the pic above. It took me a little while to realize that the return gallery is the raised portion of the block below the engine mount boss running the length of the block. Hopefully now I can get my system plumbed in my race car and get closer to firing up that engine!

Glad you got it figured out!
