Default Down in the valley . . .

My intake manifold is out. It was startlingly clean underneath -- it shouldn't have been startling, I suppose, that a low-mileage car was clean. There was no oil in the valley, but there was some fresh coolant (which bothered me until I realized that it probably oozed out when I loosened the FPR and damper brackets). The knock sensors are pristine.

I've installed an ARRFPR, new fuel hoses, and new vacuum hoses. I'm planning to powdercoat the intake and valve covers (that black wrinkle finish looks good to me) and replate some of the fasteners and other components (would black zinc hardware on a black wrinkle intake and valve covers be too much?).

Any other WYAIT suggestions?

Looks good Mark; any trouble getting the FI electrics off?

That new FPR looks like an adjustable unit from 928 SP, yes?

WYAI...........fuel lines; they're old and any other suspects under the intake like the flappy actuator and bearing.

Of course you know you've jinxed yourself and it'll leak like crazy now, right?

Hi Malcolm:

I never have any trouble getting the FI clips to release. Just a firm side-to-side wiggle and pull or two on the plug and one side, then the other, will pop off. The problem I had recently was a couple of clips fell off the plug afterwards when I wasn't looking. They are held on by a bit of melted plastic over the closed end. That plastic can fall off with age and the wire clip just slips out. I bought some Ford replacement plugs recently ($2 each) and their clips have the tips bent over so they cannot slip out of the channel and don't require the melted plastic to retain them. Still work exactly the same as stock otherwise. I just transfered the wire clips.

47K miles. Why did you remove the intake?

No trouble getting the FI electrics off. I found that the best way to disconnect the injectors was to pull the rail off, then use the Bosch tool to pull the connectors. Otherwise, there wasn't a lot of room to get the Bosch tool in between the rail and the valve cover with the rail in place. The last Bosch connector to the throttle body was a bit of a bear, but I was able to remove the wire clip and pop the connector right off.
The FPR is an adjustable unit from 928 Specialists. If my 928 Specialists X-Pipe ever comes in, I may need a little more fuel.
Do those fuel lines look old to you? I already replaced them!
I probably shouldn't have disturbed it, and it may well leak when I'm done, but I wanted to make sure everything under the intake was shipshape. It is -- all the rubber is sound and supple. But, to be safe (or tempt fate even more), I'll do the oil filler neck gasket as well.

What do you think about a dark grey wrinkle finish on the intake and valve covers, and black hardware (screws, throttle quadrant, fuel rails)?

Black on black on black, NICE.

That is a beeyooty. I think whether you go with dark grey and black or just black w/more black I think it will look really nice in there.

Mine is grey and I'm thinking black with maybe a little red and yellow in there for contrast.

All the vacuum lines - especialy the ones under the mainfold. I used small zip ties for the smaller lines (eg to the flappy actuator) so that they can't pull off.

I am failing emissions; the symptoms are consistent with a vacuum leak and nothing in the secondary vacuum system seems to be leaking. So I figured I'd take a look under the intake and make sure everything looked good and replace anything even remotely questionable.

(I am now convinced that the vacuum leak is inside the brake booster. If I had a vacuum pump I'd test the booster for vacuumtightness right now. Since I don't, I'm thinking of ways to use my Shop Vac as a vacuum pump.)

Besides, I had a growing pile of replacement parts from 928Intl and 928GT (fuel lines, FPR, vacuum hoses) to install.

Also, I wanted to refinish the intake (even after only 47,xxx miles, the paint is peeling like crazy).

Aside from that, if you can't take it apart, you don't own it.

Roger could have checked that for you at Third Coast. I saw that he had his Mity-Vac with him. Although he didn't have his Kempf tool

Why not powder coat the coolant bridge while you are in there...

Thx Bill, I assume you mean after the rail is removed?

Now that I've succumed to winter the intake is coming off soon.

I just installed the same AFPR in my car as well as a FP guage..........interested to see your results.

No, the fuel lines do not look old, I only made the suggestion as while you were in there not realising they are new.

I'll be doing same soon and shall post outcome.
