My guess is that the headers will hang up on that "fence" that surrounds the battery tray. Later spiders don't have that "fence" (OK, they have a removable, plastic one).

carbs too huh?
I'm not saying the engine won't come out with the carbs and airbox in place; just that it's one more thing to bang up the fusebox and fenderwell and it will get in your way when you want to line up the R motormount.

Oh it's not that bad. You can reach under the carbs with both arms, R arm in front, L arm behind, and install the washers + nuts. It's worthwhile chasing the threads on the carb mounts to make sure the nuts will spin by hand.

Also: There is some play in how the carb mounts fit the manifold, carbs fit the mounts. Assemble all this while the engine is on the stand - if you just bolt the mounts + carbs without test fitting, you may find that the airbox won't span the two carbs properly.

That's one thing I wish I would have thought of when I pulled the engine out of my '88.

thanks for that tip!

thanks for that tip too! i didn't realize it would bang around that much.

so mount the carbs to the airbox on the bench, mount the carb mounts to the manifold on the engine stand then mount the carbs/airbox to the carb mounts once the engine is in? or mount everything on the engine while on the stand then remove what item(s) for reinstallation after the engine is in?
thanks Jay

I guess either way would work, though I tend to do the latter. The two carbs plus the airbox is sort of an unwieldy assembly to try to put into place.

Actually, now that I think about it, it can be as simple as leaving the carb-to-carb mount nuts loose until the airbox goes on.

My point is simply that there is some play in the carb mounting and carb mounting holes, so you can end up with some variation in the carb-carb spacing. Unless you verify that the eight airbox mounting studs/holes line up before cinching down the carbs, they probably won't line up.

Ok got it! I pulled 'em along with the header. I loosened the left motor mount from the block as well so that I can take it off once the hoist is hooked up and the weight is off. I'll take the oil filter assembly off too. I should be able to pull it tonight after I finish fabricating a longer boom for the cherry picker I'm using.
How's the weather in San Juan Capistrano right now? Sunny and 72 I would guess. I love that place! We're moving back to So Cal when I'm done at Boeing in a few years.
Thanks for the help!

I'll take the advice about the blankets and hood latch to heart!
Thanks Kevin

Also, most engine lifts have five or six chain links that hang down to the lifting hook. Just by removing the bolt and inserting it through the second link, it shortened the excess chain by five inches; thus extending the 'reach' of the lift.

Paul Spruell uses a nylon ratchet strap from the back of the engine (valve cover web) to the lifting chain to control the angle of the engine. I've seen this recommended on his SpruellMotorsport.com website -unfortunately it may be gone now.

I was wondering if that section of the valve covers could be used

If Paul Spruell says it's OK, I wouldn't challenge him. Still, I don't view that cast aluminum web as structurally strong. I might use the cam cover web to tip the engine/trans a bit, but sure wouldn't expect it to support much of the load.

Honestly, the engine/trans tilt is a non-issue. Just put the lifting hook on the second pair of head studs and the engine/trans will come out at the right angle. Once it is almost out, when the oil pan is above the radiator, I usually manually lift the tail of the transmission so it will clear the front sheetmetal. That's all the tilt adjustment I ever need.

engine is out. thanks everyone for all your collective help. i think i used every single tip i received from all of you! i was able to do it myself without any scraping, wire pulling or metal bending
now for the investigation as to where the oil all over the outside of the engine is coming from. i think i may rent a heated pressure washer to clean that nasty engine bay!
regards

Thankfully Alfa made it out of aluminum so it would be stronger.

1969 1750 Spider Veloce w/dual webers, 1969 1750 Berlina, 1971 1750 Spider Veloce w/ dual webers, 1985 Spider Veloce 23,000 orig. miles, {Two} 1986 Spider Veloces, 1987 Spider Veloce bought new, 1988 Quadrifoglio, 1991 164S, Plus several more. I think they are breeding.

well done getting it out!

To be honest, I’m not seeing much oil in that engine bay..... I’ve driven much worse.

Be interested to see the data plate in the RH firewall (near the fuse box).. never seen that on a Duetto?

'66 1600 Duetto | '73 1600 GTJunior | '03 156 1.9JTD Sportwagon | '11 Giulietta QV (wow, revelation) | I really don't need this many Alfa's...

Thanks! I was surprised how easy it was to lift out after having been such a pain to disconnect everything. Oh well, it'll come out that much easier the next time
That data plate you're referring to is all written in German. The car has euro spec turn signal/running lights, headlights and a KM/H speedo too; so I assume it was originally delivered in Germany.

yes, that's a german "Typenschild" (or ID plate) put on every alfa sold in Germany.
So most likely your alfa would have been first delivered to Alfa Romeo Frankfurt.

It states: type, chassis number, permissable total weight, year of manufacture, front axle load limit and rear axle load limit (in that order)
