>>As far as I know from what I've read, the fording kit is the >>waterproof distributor with screw on o-ringed spark plug wires,   Kit... as in option? I *think* the waterproof distributor was pretty common, except I think there were two types of those. Both have the screw on o-ringed spark plug wires type cap, but the distribtor housing was different. One had an airline that passed threw it and the other didnt. Not the vacume adv line, but a seperate line that screwed onto one side (enter) and screwed onto the other side (exit). All meatal lines, thus, on some you would see 3 lines (1 in, 1 out, 1 vac adv) and others just 1 line (1 vac adv).   >>along with waterproofed trans, engine and diffs (vents located up high).   Roc! Can you get a pic of those "vents located up high" thing! In that all difs have a vent, but, I have seen aftermarket 4x4s take that vent and extend it via a line to a high point on the body. Is that what your describing, or, are you saying the vent is on the highest point of the diff? ie near the top of the ring and pin gear housing area?     >>The gas tank breather and intake thru the oil bath filter are the limiting items.   Hmmmm, ive seen them extend the gas tank breather too... but I didnt think NISSAN did anything like that stock or kit or option?   >>All three of my Patrols have it so it was fairly common I assume.   Agreed.   >>I did notice one difference though on one of them. The cover for >>the oil bath filter has no external openings other than a part of it >>that faces aft towards the firewall.   WOW! I have never seen one like that! I have seen one where the side slits were not visiable... but this one has a whole seperate breather pipe... very strange! Can you get a few more pics of that from differnt angels. Upload them to the picture section and lable them DEEP FORGE BREATHER KIT or something like that.   Also, what is that thing at the END of that TUBE facing BACK on TOP.. It allmost looks like it has some pre-smog stuff on it... or is that some kind of valve that would shut off if water came in...   Also, what is that thing at the END of that TUBE facing BACK on BOTTOM..it looks like a hose going back towards the fire wall... what is that?   Also, what is that thing way off to the left, just infront of the heater blower... is that a carb sitting there? spare part? what the heck is that?   Also, your heater blower looks different, it seems taller, and seems to have a flow door in it, mine dont have that.   >>The other two have rectangular slots in the leading portion of the oil bath cover.   That is what I got.   >>I would think that the aft facing cover opening is the best but   True, but, it would be easier to extend that via a tube and run it up even higher, Ive seen that done on some land crusers and rovers, they run a tup up along the windshield. But, that would mean that your cap that goes on top of the airclearer (not shown) would have to make a good seal with it and the carb!!   >>your still limited by the gas tank breather unless you modified it or >>as Fud pointed out had a watertight cap.   True... sometimes those breathers have a little snorkel thing in them, thus if you dont stay submerged too long, as in crossing a river, it would close and not be a prob.   All in all.. PLEASE take some more pictures of this thing! from different angles and such, I have never seen one like this, very cool!!!!   Grant

http://groups.msn.com/NissanPatrolClubA ... otoID=1401   that shows a few of the mentioned watertight items. I can see that 67 had an org heater at some time (now?) by the fresh air intake to the left of the radiator....   BTW...nice 69 Patrol David....shouldn't be to hard to sell it, good luck.

Hey Grant !That thing at the top of the tube facing back of that air cleaner on the "deep water"ford kit is the vaccum diaphram that operates the trap-door for that hose comming off the bottom and facing the fire wall. The question that springs to my mind is what actuates the vaccum to that diaphram and where does that hose go? I suspect it may plug into the heater box and what we may be looking at is a Patrol equipped for cold weater operation.The reason I say this is because it looks quite similar to most air cleaners installed oncarburated vehicles up here in the Great White North. The winter temps up here can goas low as -40deg. for days and often weeks on end. So to combat the anoying problem of carburator freeze-up at those colder temps the factory installed a system that looks identicalto what we are seeing in this picture. The vaccum to the diaphram is controlled by a temp. sensitive bi-metalic switch mounted in the top of the air cleaner cover. When the air temp.entering the air cleaner drops to a certian point the switch opens allowing manifold vaccumto be applied to the diaphram hence opening the trap-door while at the same time closing off the snorkel. Causing air to be drawn through that pipe on the lower part directly beneaththe diaphram. In our case up here the other end of that pipe is connected to a shroud that encases the lower part of the engines exhaust manifold right around the spot one would find the heat riser valve. This in turn of course pre-heats the air going into the air filter and pre-vents the carb. from freezing up. However in the case of the patrol I do not see any shrouding around the ex. manifold and considering the direction that hose seems to be heading leaves me to speculate they may have used the cab heater core to serve the function of pre-heater for the air intake. Either that or that hose connects up with an intakeport inside the glove box or in the dash and really is part of a deep water fording kit withthe vaccum to the diaphram being switched manually by the driver from inside the cab.Very interesting!Scooter

I think your guess of "cold weather" might be correct Scooter. I would be suprised if it was part of a deep fording kit. Cold weather makes most sense to me, the cold weather kit is listed in my parts book. Regardless I think we are looking at a very rare equipt Patrol for here in USA......

Hey Scooter Dave n Fud   Huh... cold weather huh? That is ironic, in that the system you described, where the shroud around the exhast manafold and that control valuve at the intake of the air cleaner, ie that thing point backwards is very simular to the early smog systems down here in the Great Hot South! In that early on car makers trying to meet CA standards realised that the worst case emissions were at start up, thus they wanted to get it up to temp asap. So, I agree, it doesnt look like a deep water kit as much as some cold weather thing like you described... or a very early attempt of NISSAN to meet CA smog standards... It all started to kick in around 69... and I heard one of the rumors why the PATROL was no longer shipped to the states was they didnt want to deal with the smog stuff, yet, in AUS I see that they did deal with it in the sense of carbs and such near the end.   Grant

Well Grant...   I am unfamiliar with smog things having lived in Oregon and Wyoming my whole life, we never have had to worry about it. You could be right, I really don't know. I do think that Scooter made a good guess and I am thinking "cold weather" makes most sense. Patrols were outfitted for this purpose, just like Patrols in hot regions had no heater. I am curious to know though as "cold weather" and other set ups are listed in my books but I have never seen them and am unfamiliar with these things. It would be cool to know....just like a lot of other small mysteries about Patrols.

The cold weather thing sounds right to me. I looked at my microfiche and it shows a Switzerland version of the air cleaner. It looks similar to this picture other than it has a paper element instead of the oil bath. It has the snorkel thing going toward the firewall. It had a tube running down to the exhuast manifold much like our cars do today to heat the air faster on start up. It doesn't show a vaccum diaphram that operates the trap-door for fresh air intake though.  Is it possible that someone welded the snorkel from a newer air cleaner to an oil bath breather?  There are some pretty heavy looking welds that attach it. Just a theory.  Also the heater blower is facing the wrong way. Most pictures I've seen the air intake oppening faces toward the front. As Fud stated "I can see that 67 had an org heater at some time (now?) by the fresh air intake to the left of the radiator...."  That is where the hose should attach and run to the blower. Maybe it's from something else??? The flap would help in warming it up ?????  Is the snorkel attached to the heater blower? Can't really tell. Need smoother pictures to tell. Sorry Roc8man I don't mean to pick apart your Patrol. I was just guessing at  possible options.          Grant,    You said "In that early on car makers trying to meet CA standards realised that the worst case emissions were at start up, thus they wanted to get it up to temp asap."  Mine has a thing called a Emissions Vacuum Control Valve (according to Chilton's Datsun 61-72 repair guide). It has tubes attached from a manifold vacuum port and one from the carburetor vacuum port that run to the valve then it attaches to the vacuum advance line. It says it has something to do with cold starts and advanced timing on deceleration.  I'll try to get a picture of it and scan the page from the manual. It tells the 2 methods used on the Partol for emission control.            Keith

I took a couple of more pics from different angles tonight. I'll look at it better over the weekend since it's easier to see during the day. You can see the snorkle tube is not attached to anything right now. I'll look to see where it may have gone to.   That's a spare carb strapped in there. Good eye Grant.   The heater looks original since there are no other holes in the firewall.   The oil bath snorkle also looks original. The "heavy welds" your seeing is caked on dirt.   I looked inside the end of the snorkle and it does have a flapper that is connected to a vacuum line connection so based on what I've read so far, it does appear to be a cold weather option. This Patrol is originally from Colorado so that could be.   Here are the pics.   DavidAttachment: Mvc-711x.jpg

Hey Roc8man!   Thanks for the pictures! You should add them to the PICTURES section. Looking at this pic:   http://www.msnusers.com/NissanPatrolClu ... chments/53   It does appear to be a cold weather option instead of a deep water or smog thing. And it kind of makes sense, initial when we saw that the side ports on the body of the air intake were replaced (filled in, ie none) with the long intake pointing to the rear it gave us the impression that it was for deep water, but, considering the top of the air cleaner, ie the lid, is NOT sealed, and only an inch or two above where the intakes use to be... well that would be alot of work to gain an inch or two of deep water action, so it is defintally NOT a deep water thing. And, it is just too early for the smog thing, so, that leave cold weather. Which explains what the side ports are removed and forces the air intake to come in that long intake pointing to the rear, where at the entrance there is a valve to direct the air from fresh, or (down) where I assume there use to be a pipe that connected some way near the exhaust manafold to get the heated air coming off the exhast pipe area.   Only thing left to figure out... why is that valve that directs the air from fresh to heated controled by a VACUME... that realy makes me think smog... in that considering how MANUAL every thing was back then... you would think there would have been a manual lever/knob in the cab to control the selection... Hmmm well.. how did the smog stuff back then detect cold starts, which in turn contrled the vacume line that controled the intake fresh/heated thing... I cant remember off hand... cold starts I belive had more or lesss vacume... once the engine heats up it changes... Hmmm well I guess the same thing would work for cold weather kit? Well, not sure, Im sure it is not deep water, and just dont think it is smog, so must be cold weather!   Grant

Good analysis Grant...   What if the top to the oil bath is missing though? It looks like it could have made a watertight seal fairly easily with bolt down through top, ect. I still think it is "cold weather" gear but maybe someone moved this oil bath, adapted it or something for a snorkel. Only reason I say this is that like pointed out, the air intake is pointed rear, right at the air vent in hood. The rectangular intake looks like it would be a good fit with a rectangular hose for both the oil bath intake and the hood air vent. It is pretty much not happening to have a snorkel with stock oil bath, converted no probs but....this set up is the only stock looking thing I have ever seen that would be easy to adapt a snorkel to....It kind of looks like the heater had welding on it where the intake is, possibly so it could be turned on it's side to allow clearance for the snorkel? Anyways....intresting subject.
