Thats a bit of a pain, sorry to hear that. Oh well, the t-belt and crank should take you only a few seconds knowing you've done it so many times.
The soap opera continues to have its twists!

here are some pics of when I did mine.
as for the cover take the 164 cover to a drill press with a flat cutter (I used a end mill) and set the stop so the cutter just hits the top of the mounting holes for the VR pickup(with the round tube things pulled out)
now put the Milano cover and mill the surface down to the same depth.
then put a drill bit in that will just fit inside the threads of the 164 and with the 164 cover set the depth of the drill and set the stop then switch back to the Milano cover and drill it to the depth. then change to the correct drill for the tap and redrill but do not drill any deeper then the first drill. then go back to the 164 cover with the drill that will just go where the tube things go again using the 164 cover to set the stop. then drill the Milano to that depth. then tap it. put in the tubes and the VR pickup.

also you will need to ovel the back 2 bolt holes see pic. and I guess you will need to do what I did and get 2 pumps one 164 and one Milano. take the insides out of the 164 pump and put it in the Milano casing. The Milano sets a bit lower so you need to grind down the the gear some so when you put on the nut it does not bind. I cut mine so it had a tiny bit of play

Uh, does not sound familiar. I think we are taking different approaches, or you may have a different style Milano donor engine (note that there is an early and a late style Milano 2.5 - mine is a late). Similarly, there is an early and a late style 164 engine as well - my 164s engine is a late style as well. Anyway, we will see. Regardless, thanks for the pointers

Jes - when you put the Milano front cover on the engine, you will have to drill and tap two holes for your crank pickup (is this what Slyalfa was saying as "VR pickup"? What's a VR?)

The problem is, there are four "blanks" in the casting for the front cover. At least for my application, the correct location was the topmost blank and the third blank from the top. Yes, I picked the lower pair and the car wouldn't start, and at worst, backfired and blew the plenum off

VR = variable reluctance.

They are pretty close, and I don't remember if the 164 front cover had four blanks ... so I had a 50-50 chance of getting it wrong the first time.

The cover "thickness" isn't an issue since the CAS pickup area is much wider than the width of the 60-2 wheel's teeth.

You know, now that I think about it, I wonder why Alfa put two possible locations for the CAS, probably around 15 degrees apart?

my 87 Verde cover was not milled so if I just drilled/tapped it the pick up would be way to far out. also it is hard to know how far to drill. so that is why I used the 164 as a reference. also I think mine had only one mounting spot. if it had a 2nd spot I think I might have used it to clear the alt. belt. as it is it is tight.

this is the best pic I could find of it

Nizam,
I NEED THAT extra front cover you have (by Friday). Oh well, we'll see if APE got it shipped... I really prefer not to scavenge my 2.5, though it already lost the thermostat stack, the oil pan, the oil pump pick-up, and soon the flywheel and bell housing as well. This evening I did a lot of the little things: oil pump pick-up, moved studs over, removed others, took out steel inserts, ... No pics since it involves top secret tricks

Just kidding, too late...
Jes

It's ok. I'm keeping my fingers crossed that APE shipped it Wednesday (so that I'll have it for the weekend). Worst case I guees I'll have to pull it off the 2.5 although I would like to avoid that. BTW, the front cover on the 2.5 only has two mounts (not four like yours as shown above), perfectly matching the 164s front cover CAS mounts. Though, it still requires drilling and tapping.

Well, didn't receive the used lower front from APE. Hence, no other way than scavenge parts off the 2.5 engine.

I spent this morning and early afternoon pulling the lower front cover off the 2.5, modifying it for mounting of the 164 crank angle sensor, pulling the new timing belt + tensioner + crank pulley + lower front engine cover off the 164. I also had to put it yet another front crank oil seal as the new one on the 164 cover is obviously of little use

Anyway, find below some pics of modifying the Milano lower front engine cover - straightforward and self explanatory. Mostly drilling and tapping. Oh, the first pic is the old dirty 2.5.
