Difference between 81 and 82 non turbo 1.6 ??

[DieselVanagon]

Is there any difference between a 81 and 82 1.6 liter non turbo motor?
How can I tell the difference between 1.5 and 1.6
Besides Oil pump /pan what else do I need to swap using a 1981 rabbit engine in my 1982 Vanagon. Flywheel?

I think the 81 will have 11mm headbolts but the 82 might have 12mm (changeover year). I might be wrong with those dates. I can never seem to remember them

1.5s will be stamped with a D on the back of the block and 1.6s will be stamped 1.6D

i don't know what all markings are on a vanagon gas fly wheel but as long as it has top dead center then the fly wheel is fine.  like burn says tho, 81 was the cross over year for the 11mm to 12mm engine, half the cars from the that year are 11mm bolts and half are 12mm.  it might have to do with where they were built, my jetta had 12mm studs, and my rabbit (us built) has 11mm studs.  the way to tell a 1.5 from a 1.6 is to look on the back of the block, it will say either 1.6 or 1.5

My 5/81 Jetta (German) has 12mm head bolts. Pretty sure it's the original engine. Is your Vanagon already diesel? If not you're going to need quite a few expensive/rare parts. Also, a NA Vanagon is a very slow beast.

nice to see another user from the Southeast.

I'm fairly certain my 82 1.6D has 12mm headbolts. It is in a crate right now. I need to decide what to do with it. It has a Giles pump, and I still swapped it out for an AAZ, and I'm driving a little rabbit. I'm with Andrew. If you are going to go to all the hell and expense of doing a swap, go ahead and get enough power to conquer the onramp while you are at it.

Good luck, and welcome to the forum.

if you look at the front oil drain on the head behind the injection pump, all the 1.5 engines had a small return. and all the 1.6 engines had big returns. if its about as wide as your thumb, its a 1.5, if its as wide as about 2 thumbs, then its a 1.6. thats much easier than getting a mirror out or climbing under the car. also, if you are good enough, you can just look at the code and know what it is.

There is no way that I would ever install a non-turbo 1.6 into a vanagon that I owned.  Ridiculously slow and I'm o.k. with slow.  It might behoove you to consider that if it needs an engine, then now is a great time to install a more powerful engine.  In stock form even the 1.6TD is inadequate, IMO, but it's a HUGE step up from the 1.6 non-turbo.  

Assuming the vanagon already is a diesel, you'll also want to swap over the valve cover, intake, exhaust, injection pump, the injection pump bracket, the timing belt cover along with the flywheel and clutch assembly.  You might want to swap the vac pump if your vanagon has the rotary and the rabbit engine has the diaphragm pump.    

My Vanagon is a Diesel already and I’m trying to use a 1.6 liter Rabbit for the short term.
I was hoping to use the pump from the rabbit and wonder what the difference to the vanagon is.

Thanks for the welcome. I know the vanagon will be slow but at the moment I like to use what I have and get it running again.

What does a vanagon weigh? The 1.6 n/a is very slow in my truck which weighs what a ton?

[DieselVanagon]

I'm just trying to get Vanagon back on the road regardless of speed. The only thing I need fast is to get it running again. Some how someone has accumulated 109.000 miles with a 1.6 Diesel in it.

The other option I have is to use a TDI AHU  that it available to me. I do not want to mess with engine mount and pump conversion at this point, hence the question about running the TDI non turbo. If I could make this a bolt on for now using the 1.6 intake and exhaust manifold maybe even the pump with lower pressure injectors that would be great. Anyone knows?

 

[DieselVanagon]

The AHU would bolt in.  The intake and exhaust would bolt on.  The intake ports are wrong, but it would work.  The oil pump is also wrong, but it would probably work o.k.  Long term you should get the 36mm vanagon TD oil pump to fit on the AHU.  I've never tried running a TDI with a 1.6 pump.  If it did run it would run very poorly.

Thanks these are great news to me!
