Welcome to the forum and I'm sure everyone will want tons of pictures of your new toy in action.
ryan congrats enjoy your new ride i drive mine every day just like a car because i can got a question on the 1600 rear main seals yesterday i noticed a puddle under my trac checked it and noticed oil driping from the rear of the engine do theyhave a rope seal or a full circle seal

There are a few places that can leak oil between engine and transmission.
I can leak from case halves or the cam plug. Both of these require splitting the case, but are not as common as either the rear main seal or flywheel oring.
The rear main seal is a full rubber seal that seals the case halves to the outside of the flywheel. Then there is a rubber o-ring in the inside surface of the flywheel to prevent oil from coming out wheel the bolt holes on the flywheel are. If you are taking it apart replace both rear main and o-ring.
If this is on the motor with the excessive end play ...That can definitely take out the rear main.

thias has worried me since i put the motor back into service it was a chunk of rust and corrosion under the hood the thng had sat for over 5 years with out running so i kind of expected leaks from every where and was suprised when none appeared i have been driving this rig since september and this was the first time i had to add oil to it the engine was supposedly rebuilt and only run a season or two before the owner passed away so i have no clue what went into the rebuild or how competent the guy was im now running 5w40 synthetic in it starts good at -15 with no oil usage till the leak showed up so i'm guessing he did some thing right.any thing else you can think of while i have the engine out that i sould look at now that you know some of the history of the engine vw info is a little hard to come by up here.they wern't popular cars in ak .

Just talk to the shipper and the snow trac should be here on the 10th. I will post some pic when it gets here.

hey Ryan i'm now having to address my end play problems with a new crank and block the guy putting it together in wasillia told me he still has your wiper motor pm me your address and i will passit on to him. your snow trac was in his shop not too long ago to get the trans rebuilt sounds like your rig in well taken care of

Snow trac delivery delayed until Tuesday morning. The anxiety is killing me. The shipper says he has had a blast loading and unloading it from various trucks. I am getting kinda irradiated that he is having fun with it and I'm sitting here waiting. I will post pics when I see it.

in the guard every time we shipped a susv out seemed like northland had to tru 4 or 5 different flats before they had one that worked also i fund out that its not yours the guy in wasilla had a wiper motor for it was the fiers one you tried to get that one went to ca but he had also worked on yours and thinks it's one he did a 1600 conversion in.

I believe you are right about the 1600 conversion. The original motor was damaged when the flywheel cam off. The vw guy out there built a motor for someone with a bug and couple of days later he rolled it. He then bought that motor back and later installed it in this snow trac.

YES, snow trac is here. Serial #58025...I think that makes it the 25th one built. It was not running very good last night. I could hardly get it out of 1st gear. I found it was only running on 3 cylinders. Put new points, cap, and rotor on it and drove it this morning. Can now start out in 3rd gear and have had it going around 20mph in my parking lot. Still needs some work before I take it on any long trips. I will post some pics today if I get a chance.

Do you have an initial impression of how the 1600 VW will perform in the Snow Trac at altitude?
i bet it works ok for him he wont get high gear on a hill in soft snow i bet it pulls pretty good for the yerrain though.
utahwilson
New member
curious as well about the altitude. Mine doesn't run very well at 7500'. I think leadviller mentioned he is at over 10k.
ts all in the how you tune it he should be able to get it to run great but if he gets to sea level i bet it wouldn't run worth a hoot at sea level thats the beauty of efi its seld adjusting

I just set timing and dwell took it for a drive...blew my mind. There is a hill near my shop that is about a 45 degree pitch and it went right up it. I can't believe how capable these machines are. Tuned properly a 1600 single port puts out plenty of power for these machines even at 10,152 feet above sea level. I'll keep you all posted...hopefully with some pics soon. I've been having too much fun to take pics so far.

Ah Leadville, US capital of low birth weight babies (it's true!) and gasping internal combustion engines. At ~10,100' above sea level, it's tough on man and machine. Anyway, it's a real neat town that has a snowcat feel to it. I used to visit as often as I could.
His 1600 VW engine will run like a 1200 of similar condition at sea level. Gasoline, diesel, n/a, turbo, efi, etc., you can't get around the fact that there are on average about 1/3 less oxygen molecules there than at sea level. Turbo would be a real boost to cramming more oxygen into the combustion chamber, but a turbo in Leadville will still have ~1/3 less hp than at sea level.
I agree with dds, we should all have EFI. The mass airflow sensor measures the amount of incoming air and automatically adjusts the amount of fuel. With the 'ol carburetor, well it's pretty messy isn't it with jetting and all that crap to achieve only a rough approximation of ideal stoichiometry for a narrow set of altitude, rpm, and load conditions.

Ok, here's some pics.
Looks like it's in great shape. I'm guessing the exterior has seen some new paint in the past. Either way, looks good!!!
sharp ride what is that box in the corner of the pictuer on the left frnt picture. i also like the storage aera next to the driver i might box mine in the same way. it is amazing how clean that stuff stays when its away from the salt water the engine tin and alternator looks like new.
Hey dds speak in english

I believe the box you are talking about is a propane heater installed by the previous owner. It works well and is installed nicely, but a 20 gallon propane tank takes up too much room. I have ordered a 5 gallon tank that will fit under the bench seat.
there was a silver box under the hood by the left front fender next to the voltage regulator. nice heater the other thing that is cool is allthe extra glass as far as the propane goes try too find a dot tank like on a fork lift you can put out side you dont want your tank inside if it gets too warm the vent can pop off and release lpg in your cabin. lp is a safe gas until your fuel air mix gets just right and you don't want it contained in your cabin .

Those silver boxes (one on each side of the engine compartment) are oil containers with valve that you can open and let oil drip on the chains for lubrication. I don't know if those are stock, but it looks like they are.
