OK, I've searched, found, and read a lot about the oil/vacuum pump worn tang and bow-tie slot issue.
So far all I read is "it's normal". I can't put this back in like this.
My tang is severely worn - now diamond shaped with sharp tips and the slot on the vacuum pump is seriously "bow-tied" - like bozo the clown.
I'm gong to be looking at well over 2K in parts by the time I'm ready to put this motor back in and this pump has got to be changed.
I think I found a new pump for about 75 bucks but it doesn't quite look the same as the one I have (only two bolts hold the suction tube to the bottom of the pump on the new one) mine has the suction tube integral to the end cap and looks longer than the one on the web site.
As I don't know what model car, or year this engine came from, it would help if someone here can make some sense of the numbers from the block (if it's possible). There is 1.9 TD cast into one side. There are the following numbers stamped on the smooth surface on the RH side of the block (facing pulley end between cyls 3 & 4) they are: 370 015. 80HBH is cast on the right below cylinder #1. 140 4 is cast to the right of cyl 4.
OK, The AAZ is listed as a Passat engine, Canada between 91 & 98
http://www.autoshoppingcenter.com/Volkswagen/vw_enginescode.htmlThere is a long number cast at the lower side of the block but I can't make them out very well.
I realize that this motor has had some "refinements" done for sure as it has a 1.6 IP and possibly a 1.6 oil/vacuum pump. As it is a Vanagon retro-fit there may be other bits that are odd but I hope knowing basically what it came out of will help me find parts easier.
Most sites want you to begin your search with a model and a year so I start guessing.
Any help appreciated.
Thanks
