If it's standard shift there's a plastic cap on the top of the bell housing.
The there's marks on the flywheel and a pointer. You may need to unscrew the outer plastic part to see the pointer. JoBo "Glenn Roesener" > wrote in message 36... > Ok, this seems so silly.

silly timing question (how-to)
Ok, this seems so silly. I normally work only on Air-cooled...but the
daughter's home from college. I went to replace her cap and rotoron her '90 Jetta GL (1800 engine), and wound up dropping a piece of something into the distributor. Long story short...I had to take the whole thing out to shake the silly thing out. Now I realize I have no tune-up data, and can't find a mark on a pulley to save my life anyway. So...how do we set timing on a 1990 Jetta? It's 40 miles to the nearest auto parts store, so I'd hate to have to travel all that way just to buy a book today. Any help is deeply appreciated. |

You need to set the timing at about 2500rpm so have someone in the car keeping up the RPMs for you. |

This Is how I know to do it if it a digifant fuel system:
Warm car to operating temp, unplug blue coolant temp sensor at the top of the block , rev car three times past 3000 rpm to clear computer, maintain 2500 rpm while viewing mark on the bell housing after removing green inspection cover, set timing to +6 deg mark , plug sensor back in and you're done . > From: Glenn Roesener > > Organization: TDS.NET Internet Services www.tds.net > Newsgroups: rec.autos.makers.vw.watercooled > Date: 19 Sep 2004 13:23:27 CST > Subject: silly timing question (how-to) > > Ok, this seems so silly.
