N52 oil pan design for Z4 engine arm based swap

[hoveringuy]

yes, precisely.

The top can be chamfered on inside edge and/or swedged out so it has a bit of flare so the O-ring doesn't snag going in.

I flared mine a bit and it slides in smothly (the one pictured is unfinished)

The ID on the McMaster one isn't an issue, anyone that has access to a lathe could chuck that up and cut out the pocket in a jiffy.

What we need is someone to bang-out 20 of these and oil pump adapters so plebes like me without a lathe can just purchase them!

I will also say again that the OBD2 dipstick tubes with oil drainback are different, they're much fatter.

Reviewing the previous dipstick tube installments, it fits between the alternator and intake manifold. Since I don't have the SCS oil pan yet, I put a laser down (assuming my engine is straight) and it appears to line up with one of the oil pan bolts that I can use as reference.

I will likely create a cutout for the dipstick holder here.

Anywhere in that area will work. I had the power steering pump on but not that bracket it your second picture, when I mocked it up. I used the arms on my engine stand to bend the dipstick tube and get it to clear, it's pretty soft. You should be good since you have the pump fully mounted.

Still waiting on my brother's help to get the pan fully welded. I wanted to try my hand at CAD so I came up with a studded mount for the original M20 oil level sender. Happy it came out right because I had to order 7 to avoid paying the minimum order fee with sendcutsend. If any of you guys order this pan I will have extra I can send you.

Wasn't as easy as I thought it would be, the mounting holes are about 3mm north of centered on the actual sender body. The studs are M6 x 1.0.

Do you mind either sending me the CAD or actual part of the flange? I'd like to run the OEM level sensor as well. Thanks!

Thanks for the confirmation!

Please excuse the crudity of this model. Here's something I threw together quickly for the oil pick up. Prototype is printing and I will check fitment hopefully later tonight.



I will work on the bottom end later this week.

nice one, curious to learn more about that, projectjtv4

The bung was turned on a lathe to fit the oil pump and it has like a 7/8" ID or whatever the pickup is, which is just a stock Moroso 2480.

What we need is someone to bang-out 20 of these and oil pump adapters so plebes like me without a lathe can just purchase them!

I just ordered the Moroso 24840 but it won't get delivered for a few days. Do you happen to remember the OD of the tube that comes with it? Also, what was the total height of the oil pick up?

Lathing will start tomorrow evening; dipstick tube and oil pump adapters coming soon (hopefully).

Send me your address, I have extras. Just go slow when you weld it; I warped the first one pretty bad and had to start over. I also don't know if the sender will actually display the level correctly because the the engine isn't in the car yet; so no promises on that.

I can also send you the bedplate I used for a welding jig as long as you promise to send it on to the next guy that needs it and not try to make a few bucks on it when your done.

Back to your dipstick. I think if I'd put mine fully on the wing piece instead of half on that seam it would've cleared the bracket without an issue.

[projectJTv4]

I couldn't visualize the problem because I don't have the parts yet. So hopefully, these images help explain why the run is so short for the oil pick up.





Note: the Baffle Top has been updated; moved towards the exhaust side.

Sweet, thanks! I will definitely pay it forward to the next guy.

For the Oil Level Sensor, it looks like the ground wiring is switching back and forth.

Let me see if I can pull my Oil Level Sensor out this weekend. I would just need to check for continuity as the sensor is raised and lowered into a container of oil and mark when the sensor goes on/off.

Next, with 5.5 quarts of oil in the pan, hopefully this triggers the FULL connection. Slowly remove oil until LOW connection is made and determine if that amount removed is reasonable.

The pickup is one I ordered for a VW Jetta, I'm pretty sure he designed the baffle around that one. It's compact and the tubing has a 7/8' diameter, I cut it off right below the bend. Sorry I forgot to get a picture of it.

I may have missed it, but is this the right one for the current V2 oil pan?

That would make sense, I didn't think that much into it.

That part you listed from ECS is the one that I used. I still had to trim the baffle top a little to get the pan on.

Here is what I meant for the dipstick bung.

Also, This is an awesome way fabricate the pan! A bed plate.

I ordered and looked at a lot of pickups and learned quite a bit about the science behind them, including stuff like you want one that won't block flow if the pan is pushed up, there are different filtering philosophies and such

Some of the JDM ones are great but I thought the Jetta one is simple and a good, compact design.

I didn't use ANY of the tubing but the very bottom.

Yes, Thanks for that idea! I shipped it off to projectJTv4 today. He'll pass it on to the next guy who needs it when he's done.
