There is a flat spot at the top of the block, where it meets the head.  It will be between cylinders 2 and 3.  It's probably covered in grease. :lol:

1.6 NA should be ME
1.6 TD should be MF

You should add your location to your profile.  It will help us give you more informed answers!

A 1.9TD would most likely be an AAZ.  On this side of the pond at least.

A standard Canadian 1991 Jetta will have a 1.6l MF engine rather than the 1.9l AAZ... and the lines are definitely different, so you'll want to be sure.... dealers rarely do refunds. :wink:

Easiest way, short of finding the cryptic part number on the block, is to see how the valve cover bolts down.  If it's held down with 8 bolts around the perimeter of the valve cover it's a 1.6... if there are 3 bolts in the top of the valve cover it's a 1.9.

If you can direct us to a picture or two we can probably give you the Internet's opinion. :lol:

I have since cleaned my engine since these pictures....  :P

Looks to be a 1.9 based on your explanation.

Thankz for the help.
