In order to sort it out I decided to go with the single carb and manifold - who knows, before I start it up I may change my mind  ;D

I did get the engine mounted into the engine stand and mostly hooked up, however I'll going to have to sort out the oil cooler situation before I can start it. Either I'll have a custom hose made to connect the block to the oil filter housing (probably) or have them make up two new hoses and hope I get them the right length (ummm…….probably not) either way I need a fitting to match up the oil filter to the hose - that could be tricky....we'll see.

I tried to hook an oil cooler up to my green car just to sort out the hose lengths, but I could not get it even close to the right position to get a good measurement. The hoses on the coolers now are rock hard and weather cracked, so even if I could make it all reach they're not really usable. The MGB cooler that was in the Inno will not fit the green car at all, I don't know that I tried to fit the Inno oil cooler that Dan found for us as I can't get one of the hoses off, and the fittings don't match up. It's gong to take some thought to work this all out.

Spares has a variety of oil cooler hoses and fittings that you may want to look into.  I tried having a custom line made for the 66 S and no one had the correct threaded fittings.

Yes, they're really expensive too. I bought the fitting that fits the oil filter housing and has a std AN8 male end from Spares, so they can match that no problem. For the block there was a fitting already there and it also has an AN8 female end, so it also should be easy. That will allow it to run, then I can worry about the oil cooler later. Once I have the engine in the car and figure out how and where to mount the oil cooler I can either order hoses from Spares or have my local guy make them if it's cheaper. I do like the looks of the SS braided hoses that Spares sells.

Got the hose made this morning at the local hydraulics shop.....it's a little clunky on the block end but it fits and it will allow me to run in the engine on the stand and even in the car till I get the oil cooler hoses sorted. The hoses from Spares are SS braided with nice 90* ends on them and only about $50 the pair plus shipping, but this one hose from them would have been $75 plus shipping by itself! I paid $37 for the one they made me.....for that matter I can buy the fittings really cheap from Spares and have the local hydraulic shop make them up for me.

Now once I sort out a few more details it's ready to run!

I test fit the new header pips to make sure everything would clear the shifter, and it looks great. So I took them out, cleaned them thoroughly with both solvent and lacquer thinner and sprayed a coat of silver high temp on them, then hung them in the sun to dry and cure out - it's hot out today so they should cure nicely.

Last pic - don't cha love it when they send you squared off pipes?  These are the tail pipe/resonator and the inlet to the main muffler. I may have a pipe expander I can use to round them out again, if I don't a big socket and a 3 pounder will do the trick.

PITA!

IT's......A...….. LIVE!  ;D

1st start of the Innocenti engine, fired up and idles without the choke as it's pretty hot in the shop since I had to leave the door open to vent the exhaust. Also the fan is blowing (on me) so there's a lot of background noise, and I chose to put the muffler on it. The squeal is the alternator, it doesn't line up well so the belt is noisy, it got better as it ran.

Engine took a bit to crank up oil pressure - I had to pull the line to the oil filter and put some oil down the hole, then it cranked up quickly and held about 70psi on the starter motor. When it started it ran at 70, then faded to 65 as the oil warmed up - which is fine. Idles at 50 psi hot, just as it should.

Once it was warmed up I blipped the throttle a few times and it sounds really strong! Can't wait to get it in the car and put some miles on it so we can get it on the dyno too. Mediocre video taken with my 25 year old Canon Powershot.

I ran it for the recommended 20 min at 2K RPM, it only got up to about 185* by the end of the run, it mostly ran at 180* which is the thermostat I have in it. After I shut it off, I stuck it in 4th gear and started it again just to see the axles turn!  ;D

Yep, it's always a good feeling when a project starts coming together and actually WORKS!   77.gif

Now all I have to do is install the wiring harness and hook it up, reinstall the dash, put the motor in and hook it all up, install the exhaust, install the interior, take ii for a drive and then fix all the things that still need fettling! not much..... ;D

Today's project - wiring harness. The last 6-8" of the rear harness that were in the engine compartment were in bad shape, with cracked insulation and bare wires everywhere, so rather than pull the entire rear harness out I decided to just cut off the last 12 -18" of the rear harness and splice in the same amount from the new rear harness.

While planning this out (I don't want to cut anything till I'm dead sure of what I'm doing) and studying on where the wires all go and what does what - I wondered why those wires go out to the engine compartment in the first place? Is it just accessibility of the connections? What I think I'm going to do is simply run them along the inside of the bulkhead, that should tidy up the engine compartment side of things nicely. The only wires that have to run out there are the ones for the wiper motor and the wires I'll have to make up for the reverse lights switch on the engine. For some reason they seem to think here's a switch on the linkage, but I can't find evidence of one in any parts books, and I don't see any place to mount one on  the remote housing of the shift linkage, so since I have a switch on the trans that does work, I'll simply extend the wires to the switch.

I did have to remove the dash in order to hook everything up, it just wasn't possible to get my hand in behind the dash with it in place, nor to be able to see anything to know what I was doing. I didn't want to pull it for fear of breaking it but it came out OK and this will give me a chance to clean up both the dash and the parcel tray under it.....as well as repair and route the wiring.

Good idea to remove it.  I've heard the plastic on Inno dashes are fragile.   And being 4+ decades old never helps plastics at all!

The only hard part about removing it is that you have to remove the eye ball vent assemblies before you can get the dash out, the hard part of that is getting your hand in to turn them, the hard part of that is getting them to turn at all!

I had hoped to take the dash vents apart so I could repair the silver part of the eyeballs, it's chrome on plastic and it's pitted something awful, and flaking off - but I think the two halves that have to come apart are actually glued together and again - I don't want to break 40 year old unreplaceable plastic bits.

Dan says they give the car character, but I think they just look bad amongst all the other "new" inside the car...…..we'll see. I messaged the guy in Croatia to see if he had a pair he could sell but no response so far. Actually, on looking at them I only need one, the other is OK.

I also had to find some defrost hose as one side just fell apart in my hands when I removed the heater box. They do have it at MiniSpares (from time to time - the last two times I ordered parts they were out of stock) for like $20 a stick, and it's only 22" long where they claim I need 27", so I went online and found old VW's use the same size stuff in the right size and length and of course there are multiple places to get parts for old VW, only it seems they're all in California! No matter, I bought one there for $20 shipped. 

I've laid the harness into the car - no small feat itself - and now I'm sorting out what goes where, and why. (to quote Gene Wilder in Silver Streak! :-)  )

I also found and modified the bulkhead insulation I bought a while ago, it has to go on before the harness does.

When I took the gauges out to clean them and the dash around the instruments those little o-rings that insulate them from the dash just fell apart into bits, so I'll be calling Nisonger in the AM for some new ones. I don't think they're expensive but the time to replace them is now......they keep the instruments from rattling too.

I also got all the remaining glue off the speedo from the red tape that was on there.....

I called Nisonger for the o-rings this AM, (they don't list a price for these online so you have to call) and they sell them for $2 each BUT, they have a $15 minimum order, so I told the guy send me 8 of them! He said he'll get them out "in the next few days"

I guess when you're the only game in town you don't have to be like Amazon.

Since they're coming from New York, I'll expect them sometime next week, so that part of the project is now stalled, but I can go ahead with a lot of other stuff.

I had Nisonger send a replacement gauge before MMEW, they used USPS priority and I had it on Thursday after a Monday morning call.

I guess it was the "I'll get those out in the next few days" comment that makes me think it will be a while before I get them. I didn't ask him to rush them.

My defrost duct hose is on its way from Ca too.

More small bits of progress, the defrost vent tubing came in, the o-rings from Nisonger are finally on their way - he wrote my CC number down wrong, good thing he had my phone number. No joy on the eyeball vents. And more bad news, while wiring up one of the brand new glass turn signals, I dropped the lens which promptly broke.....it was hard finding a set of these in any condition, let alone brand new. Dan thinks he found a set of lenses, but they're a different brand, still Italian and it looks like they will replace these - won't know for sure till they get here....fingers crossed. Got most of the under dash and engine compartment wiring done, next up while waiting for the O-rings for the instruments so I can put the dash in and wire it up, I'll install the brake and clutch master cylinders and see about making up the new pipes.

More as it happens......

Oh and I hatched an idea for the speedo, because it's in Kilometers and I've changed the final drive, it will be wildly off. To see just how much, I installed the speedo cable and connected it to the gauge - since it's out anyway. So I'll put it in 4th gear and run the engine and at various RPMs I'll get a reading from the speedo. Once I have it in the car I can use the Garmin to see what number equals what. I may wind up putting a taped on tick at the 50, 60 and 70 mph positions, just as a reminder. OTOH, I can just use the Garmin I guess......

that sort of issue is why I put in the power port unit in the Marcos.  Its speedometer is about 20% low across the range (non-Mini speedometer coupled with what is supposed to be a 3.1 final drive).

I plan to use my little Garmin and leave the gauges alone.

I used a gps speedometer app and determined I'm 10mph off across the board.  So I just run 10 mph fast.

Yeah those new turn indicators by the pair go for $250!  Lenses are hard to find.

The Inno actually has a cigarette lighter, so I can plug the Garmin in there....I thought about adding a power port with a USB charger port, but for now I'm going to leave it stock.

I just use the Garmin in the green Mini anyway, it's easier to read than my speedo, which is off too.

Today I got the wiper motor installed and wired up, and now I'm working on the master cylinders and pipes. I bought a tool a short while ago to help put the clevis pins in and boy howdy does it work slick! I'm pretty sure that as long as the clevis isn't rusted in it will work just as well at getting them back out again too and not losing them inside the bulkhead tube.

You can see the pin installed in the second pic ( a little red smear of grease dripping off that I already wiped up) it doesn't help with the cotter pins, but then I don't use those, rather I use "hairpins", after all, all we're trying to do is keep the clevis pin from walking out - there's really no stress on the hairpin to hold the clevis in. I'm just about done with the engine compartment and ready to put the motor back in, I have a few details to sort out but it won't be long now.

Master cylinders all in, working out where to run the pipes to make sure they miss the carbs, air cleaners and what have you. It would be easier to wait till I have the engine in and carbs on so I may wait on the pipes....

I did find a home for the washer bottle and pump that I think will work and look correct. Still have to make sure it doesn't interfere with the booster cylinder or its mount.

Ran my speed test this afternoon, but as I was working by myself the results were inconclusive - It was hard for me to work the throttle, watch the tach and get the reading off the speedo....so it will wait till I have it in the car and can compare it to the Garmin.

I did get the timing set so the engine is ready to go. I have two small oil leaks that may set me back a few days tho while I sort them out.

I think my bulkhead insulation turned out nice tho…..
