430 430 Scuderia Maintenance - What Else?

Hi all, my first post. Any advice as to what else to do in the engine bay while I have this access? The rear is on stands, undertray, diffuser and bumper are off, wheels and wells off/out. Air box/inlets are out, and exhaust from cats-back is out.

I want to resolve all issues that a potential buyer would have. I’ve got the time and most of the tools (including a Launch X431 with Ferrari V11), but only plan to spend on parts that would (mostly) make a difference in a sale.

Background: I bought my 2008 430 Scuderia in 2011 with about 6500 miles. I used it for HPDE and club rallies for a few years and had it serviced by one, than another, of my local dealers. It has sat, now with 19,9XX miles on it, for a few years in my heated garage. As far as I know, the car is stock (other than an aftermarket stereo amp and speakers). Watching prices, and knowing that I have some time this winter I decided I’d do some maintenance myself and see what it might take to get it ready for possible sale. I’d never worked on this car but I have on others (non-Ferrari).

What I’ve done so far (with a lot of cleaning along the way):

- Using an “F430 30K Service Kit” from Ricambi, changed the air filters, spark plugs, serpentine belt, and oil/filter (including the screen and large C-clip in the rear sump). Then I changed the Gear Oil – putting in a new drain plug with crush washer and new O-ring on the filter (which had a little white RTV sealant on the screen).​

- F1: Replaced the Accumulator. Flushed the fluid (first bleeding the clutch actuator thru the union in the block in front of the RH axle, then thru the union up on the sub-chassis in front of the F1 Reservoir). Next, took the gear Actuator off (the 3 bleed screws were tight) and “bled” that, followed by a self-learn. I will be replacing the F1 Relay (along with many others) once I get the car off the stands.​

- As I clean up the exhaust, I am replacing the gaskets from the headers to the cats and those long bolts connecting them as well.​

Motor mounts seem to be good.

The clutch. Launch X431 says clutch use is at 65%. Is it fair to assume that, to a buyer, a clutch usage of 5% would be worth more than the parts cost? I’ve never replaced a clutch before, is it something I can do myself and if so, what else would I need (tools/parts/etc) besides the Ricambi clutch kit? I can get a little help when removing/reinstalling the trans, but other than that, it’s just me..

I have no reason to remove the exhaust manifolds, but I feel like replacing any header-to-block nuts/studs that I have pretty easy access to (to make someone’s job in the future a little easier). From what I can see so far, none are broken off, and I had no sign of exhaust leakage before, but this might concern a knowledgeable buyer (warping manifold flange):

https://www.ferrarichat.com/forum/threads/430-scuderia-broken-exhaust-manifold-head-studs.600849/

Should I try to take them off and see what’s up?

What else in the engine bay (the rest of the car comes later)?

 

Thanks guys. I have seen Ratarossa's videos and been trying to watch and read what I can,

I was suspicious when I saw this white "X" near the left-side rear-most exhaust manifold nut. I gave it a turn and, well, it was in there about a turn. Seems like I'm gonna be removing the manifolds and, along with checking out the flanges, be replacing the gaskets, studs and nuts.

The real mystery is who put that white "X" there knowing it was a broken stud?

Thanks F355Spider. I was aware of the warped manifold issue (I referenced one of the threads above).

I just got the left exhaust manifold off (I work a little slow for lots of reasons). Luckily no busted knuckles, but the most stubborn were the the hex bolts connecting the air injection to the manifold (which apparently does not exist on the F430).

As suspected, it's "warped" (bowed) in the front-back direction (at least). You can see that if i hold a straight edge tight to the first to pipes, it is about 2mm away from the outside edge of the fourth.

But that bolt has been broken for many years/thousands of miles - that's the last time a tech could have been anywhere near that (and put the white "X" there indicating it was broken, but not doing anything about it.) I have never noticed a ticking sound (cold or not) in this car.

Oh well, time to send a PM to "Windsock". Anyone else have a contact for someone to machine/belt sand my manifolds flat?

I've got all new studs, nuts and gaskets on the way, time to get the right side off...

 

I'll look around, thanks Any one have any idea what a reasonable price for machining/belt-sanding the flanges would be?

 

Thanks, I now know what it takes so I appreciate the compliment! I got the right exhaust manifold off earlier today - same warped/bowed issue by my non-scientific measurement - but no studs broken on that side at all.

But... I broke off one hex socket-cap screw from the tube feeding/into the air injection rail, and stripped out the other (2nd pic). Since I was able to get the other end of the tube off, I figure I can have them drilled out by whoever machines the flange.

Therein lies the problem. I made a couple of phone calls based on a "Machine Shop" Google search and I'm told "geez, no one 'round here does that any more". I even brought one of the manifolds into my local auto parts guy asking if he knew of any one - he suggested G&L Auto Machine in Boonton NJ. Sent them pictures and they can't (or won't) help and told me "geez, no one 'round here does that any more". I'm gonna keep trying, including some local service stations.

Does the manifold gasket's "bump" face the manifold or the block? I'm fairly certain my old ones were "bump" facing manifolds.

In the last picture, I'm installing the new studs.

Don't get to see this angle very often in my garage. Again, my goal is to address all issues a potential buyer would have.

So this weekend I’ll be taking my exhaust manifolds to a business that says they can machine the flanges flat. Fingers crossed.

Meantime I just tackled that little nightmare in the back of my head about the one broken off stud I have. Luckily, it was the rear-most stud on the left side – relatively easy access. I center-punched it then used a left-handed drill bit and went in about 13mm from the surface. I tapped in the extractor tool and used an adjustable to turn it. Whew, problem solved.

And to answer my own question, the exhaust manifold gaskets can only go on one-way.

Hey, thanks for that link – I hadn’t seen those (mostly shopping on Amazon for tools). I did see a video just before I started drilling where a guy made his own set using bolts drilled out with a drill press. If there’s a next time (hope not!), I can try to make my own first.

Once I knew the bit was in the center-punch divot, I was thinking/hoping geometry would be on my side. I checked a couple of times from the back and top as I was going in. Yes I was off, but managed not to break through the sidewall of the stud.

As fort the ports – good old’ Gumout and a little elbow grease!

 

I know I said the engine mounts “seem to be good” but what the hell do I know? They are old. I just got a set of Ferrari’s 190255 for wholesale and so since I’m down here, I'm making this a non-issue.

I just got a new transmission jack (I’m still debating whether to try to change the clutch myself) I’m using that to lift the engine while I change the mounts. Torqueing the four-per-side 17mm bolts to 50Nm and the large 24mm to 98Nm.

If anyone could double-check those torque numbers, I’d appreciate it. I got a WSM on-line version and it’s a PIA.

I'm looking for opinions, though I think I know what's gonna end up happening. Valve cover and spark plug gaskets - no real noticeable build-up around them but should I go ahead and change them while I've got a bit a space?

It seems the half-moons are actually part of the gasket.

Thanks Scott, I really appreciate the feedback. I read thru your entire "My 60k-Mile" thread, it's pretty much a guide for what I'm doing and I learned a bit. I agree that there is a significant risk of making an issue when I'm trying to resolve issues. I do want to keep cleaning things up - like you, whatever comes out goes back in better in some way.

Regarding the plugs, in my last post I had meant the spark plug gaskets that go along with the valve cover gaskets. Yes, I did change the plugs as one of the very first things.

Any additional tips on the air intake manifolds and cover? Wanting to clean the Vee and I'll change the gaskets.

 

Anyone know if the actuator on the front of the manifold just pops off the ball joint (upper or lower)? I don't see a clip of any sort but I don't want to bust anything.

This pic is looking in from the right side, into a mirror, at the actuator. Part reference #8 in the diagram.

Thanks Scott, I have read through many of AVoice's pages, but missed that one. I followed his almost exactly (one or two minor differences for the Scuderia), taking it all out in one piece. Getting everything out was a relative breeze, nothing fell out of my magnet range. I can't wait to thread those manifold nuts back on (not).

But before that, cleaning, lots and lots of cleaning. And then more cleaning...

Cleaning the fuel injectors. Anyone have a source for the O-rings?

I've got some on order but I'm not certain they're right yet. I've seen the injector (0280158124) indicated as both an "EV14" and "EV1" types.
