I have read a couple of people have had problems with the 1.9 TD AAZ engine spinning on the crank and ruining the engine. Is this a really common problem that almost all of these engines will eventually do? Is there a way to fix this other then machining for a tdi crank gear like maybe lock tight or something? Also, is there any other problems I need to be concerned with and what can I do to fix these problems and what do I look for to detect the problems. I was also wondering what kind of glow plugs are in the 1.9. I am using this engine in my 81 rabbit that was set up with fast glow plugs. Will that relay work or do I need a slow glow plug relay. What are the glow plug part numbers to replace them and what is the relay number if I need to replace that to match the glow plugs. I am doing an engine swap and can't afford much if any down time as this is my work car. The engine that is in it works for now so I can work on the 1.9 to prepare for the install but once I start I need to finish and can't wait for things like glow plugs, etc. Any help would be greatly appreciated. Do this need valve adjustments ever and do they blow head gaskets. Is 50,000 miles the standard replacement time for the timing belt. Will these engines take the same oil filter as the 1.6 NA. I know I can find the long life oil filter for the 1.6 through amsoil but I can't find one for the 1.9 so this is why I would like the 1.6 filter to work on it.
