So first post, and its not exactly on the best of terms. First off, I have an 81 diesel jetta, shes a little rough around the edges, but she gets me 54mpg so I dont complain. She had a bit of a leak when I bought it, which to me wast all that big of deal. That was until I found where the leak may be coming from. I think it may be coming from behind the crank pully, which would be not good. So I guess the question of the day would be, what do I do about it?

I'm guessing you're referring to oil? Sounds like a bad seal. There's a seal behind the crank pully. It's not too bad to replace, take the pullys off, take the timing belt off, take the crank pully off, replace seal. Get a new crank pully bolt along with all the stuff for timing belt while you're at it.

Be thankful it's not coming from the transmission side, or you'd be dropping your transmission.

thanks for the quick reply

yes its leaking oil, (should have mentioned that). It may be coming from the transmission side as well. At this point I have no Idea. With the engine and surrounding area covered in guck, I have no way to tell. The front seal is bad to the point to where it drips while the engine is running.

Question #2. If I do end up dropping the transmission, what sort of gearing differences are there between my jetta and an 80 gas model? Both are 5 speed. I ask because my wimpy top speed of 120kph leaves something to be desired.

You'll have to get the codes off of both transaxles and then determine which has better gearing and final drive ratio that would be more suited to your driving conditions and style.

The code is on the bottom of the transaxle towards the front of the car. Once you get the codes there are numerous sites that list all of the VW transaxle codes and what their ratios and final drives are.

So...a gas transmission would fit? Something for me to keep in mind in case my current tranny blows up, deliberately or otherwise

For all things gearing, here is a great source of info:

Check your tranny code against that chart.
