458 DIY Oil Change Procedure - Yes, I committed the ultimate sin!

What is the name of the drill bit to drill 3” holes?

And does anyone have an Amazon link for the 3” plugs?

For the drill you need a standard 3" hole saw (see pic). I had multiple choices at my local home improvement store.

For the plugs, I used these:

Now get out there and drill some holes in your Ferrari! And be sure to tell everyone you did it and you weren't scared at all...will impress them

With this diagram it is not possible to accurate measure the holes with the undertray off the car because the long vertical line that is the main reference point for most measurements is slightly angled and dependent on a reference bolt that is not on the undertray and therefore once the tray is removed from the car, accurate measurements can’t be taken as the main reference point is lost.

Does anyone have any different measurements that can be used to accurately drill the holes? Thank you

While I did it while the tray was on my car, I think the method would also work without it on the car. The line running from front to back goes from two bolt holes. I loosed the bolts and tied a string tightly between them to set that reference line. You should be able to do that using the holes if the tray is off the car. For the side-to-side line, I stretched a string across the flat part of the air ducts and taped it in place. That set my grid I could measure from.

Had I not done it on the car, I considered lining up the tray under the car while it's on a lift, marking the center of each hole using the grid, and then using something like a plumb-bob hanging from each oil drain just to confirm the locations. But my lift blocked me from laying the tray on the ground properly.

On my 15, there's an opening that runs along the center of the pan. This allowed me to easily see 2 of the 3 oil drains. With that visibility I could confirm I was centered on those drains using a small pilot hole. For the third hole, I could look up through the closest air duct with a light and could see the drain. I used that to confirm I was on that hole.

 

GREAT Randy !

Could you adjust the drawing for us / me ? Send it please via [email protected]

This can be a great help to all of us in future.

What diameter did you use ? Was is easy to find caps to fill the holes ?

 

Thanks a lot. These are the measurements I’m trying to get. Do you by chance know some of these distances off hand?

For example, the distance from the line of the center of the left vent that intersects the bottom of the right vent…then with the distance of that line I could figure out the height of both bottom plugs.

Watch my other MAINTENANCE posts here:

Now a maintenance schedule 458 is included

 

Unfortunately I don't know those measurements. I went directly off the image below. When I referenced pulling strings, I pulled those to match the dotted lines. I then took the measurements indicated below using the strings as the base line to locate the center of each hole.

Is there any reason to drain the oil tank before or after the other two crank case drains?

I just did an oil change and the force of the oil tank drain oil flow, which I drained first, was so strong it hit my catch can and splashed everywhere like a geyser. Total mess. My driveway looks like the Exxon Valdese and I’m calling in volunteers to help clean seagulls with Dawn soap. Kidding.

Then I drained the other two crank case drains and there was basically nothing that came out. Advice is appreciated so I don’t repeat this again!

Does anyone know the hex or T size of the two crank case drain plugs?

Anyone please ..... ;-)

 

I just changed my oil, and I used a 10mm, but I feel like there was a tiny amount of play (which I didn't like, but did zero damage to plug).
Since then, I ordered a kit that included a 11mm, so I obviously don't know if that's the correct size yet.
The good news is that I'm helping my friend with an oil change tomorrow, so I will try the 11mm and report back.

 

Pretty sure mine was a 10mm, but I've watched one vid where the guy had torx plugs instead of allen/hex. So if they're like other things on this car, Ferrari may have switched them up over the years.

 

Sometimes if the play is more than you like then using an English size fits better which is why I have sets of both. Not something you want to do if the stated size fits well enough.

 

The actual head on the plug is a hex. However, I tried fitting in a Torx bit to see if I got a better fit. I forgot which size it was, but it fit tight. But I didn't use it because it was tapered (by design), so it only made tight contact on a small section of the head, so I thought that the 10mm Hex bit was a much safer bet, since the contact was all the way deep into the head of the plug.
I'll report back with the 11mm, maybe that's the perfect fit. I'm wondering if most people don't use the 11mm, because it's very hard to find. I had to order a Hex bit set on Amazon. I will give details after I change the oil in the morning. I'm very curious to see if the 11mm is perfect, or if it's actually a 10mm, and there is just a little more play than typical? ....or is there such thing as a 10.5mm? I don't think there is

 

Assume half sizes in metric is as common as half sizes in waist or inseam.

 

I actually have several metric hex keys in 1/2 sizes!
Even the set that I bought from Amazon that has the hard to find 11mm, also has a 2.5mm, and a 5.5mm.

Checked and I do too! I also have female Torx socket set I forgot about but they are not 1/2 sizes.

 

well, the 11mm Hex was too big, so I used the 10mm one again, and it seems to work perfectly (even though there is a very slight amount of play).
Being that I don't think that a 10.5mm Hex Bit Socket exists, and that the car is metric sizing, I have to assume that the proper tool for this job is a 10mm Hex Bit Socket.
