Friend: Nissan LD20 engines, from 1987, came with a distribution girdle, not with chain, I have the manuals and I can't find Ca dena. The LD28 if I had a chain.

I would not know what vehicle comes here in Argentina, they entered as a scrapping engines from Japanese here they were sold to put them in other cars, in the entrance papers to the country it appears as Nissan LD20 Model 1987 and in some spare parts that I also got

Is it diesel or benkinero?, what displacement has and what model of Nissan is originally, these data would help us find what you are looking for.
