430 Oil reservoir cap help

So after seeing @boba fett post about his oil cap, I went on a search and found one. The person i got it from said it was from a 458, but dealer said it'll work on an F430.

So, it does 'work', dipstick is the right length and it seats properly on the neck.

However!

The notches on the 458 I'm guessing are 90d from the F430, the cavallino sits sideways on the reservoir.

I tried like heck to loosen the stem to see if I could rotate it but can't break it loose (tried both)

Does anyone know if this is supposed to come loose? Tried PB Breaker, next I guess I'd try heat but don't want to damage anything.

Any insight is greatly appreciated!

If anyone has a 458 and would be so kind as to take a picture of the notch layout, greatly appreciated, will definitely help! Thank you

This is the F430

Thank you, I was looking for the orientation in the car.

You gave me an idea though, went to the engine diagrams, same layout in the 458 as the F430

So looks like the cavallino was mounted 90d rotated. Ugh

Any suggestions how to rotate it?

Thanks all

 

Thanks gents, the more I'm at it, appears the top cavallino was not applied properly, it is otherwise same as the F430 one

Considering heat to the top to remove and reapply the cavallino circle/badge

 

Washer?

If you mean the stem/stalk, that was my plan, but it is really stubborn

Will go next level, just don't want to damage it

 

Didn't get you at first, think I see what you're saying now, just heat the bas of the stalk and rotate it

K, guess I gotta get this thing loose

 

Oh, that's loose and just sits there to make a seal, I removed it, nothing there

 

The plot thickens....

Ok, so with some leverage, I got it apart, looks like they used maximum threadlocker on it.

I have to rotate the base inside the cap 90d

It's not moving

I assume it's screwed down on top, then the cavallino cap applied

Tried 250d heat, I know it prob gets hotter than that during normal driving, anyway that didn't loosen the cavallino at all, trying not to damage it

Any suggestions appreciated!

 

Hi Allen

Thanks for the response.

I believe you are correct in that the bottom part is where it's intended to be based on the original cap and pic at the top of this thread.

I did try and move the cavallino as you describe, no luck. I think it was just built incorrectly.

I am assuming maybe they assemble the base, then press the cavallino on with some double sided tape, was hoping I could lift it, but not looking likely.

Maybe, no issue getting it hot, I'm just not sure if my assumption is correct. I really have no idea how the cavallino gets on there and if it's cemented on, its probably not coming off.

 

Thanks Allen and everyone's support, it's a little thing, but it's great to get other's perspectives when trying to figure out what the options are.

Appreciate the support of this community for all things, big and small!

 

LOL

Theoretically, I could make notches on the other side, but I'm not.
