Hi all, My 92 80-series with 1HZ has about 220,000 kms on it. Starts and runs very well, just changed the timing belt and tensioner on it to baseline that. I was browsing on the Lcool site and indications there seemed to suggest that on 1HZ engines (and possibly other similar Toyota diesels), the injectors themselves should be inspected/replaced at every 100,000 kms, and the injection pump about twice that. My truck is over the 200,000 kms level, and I don't have evidence in the few paper records that came with it that any work has been done on injectors or the IP. I'm not looking after work, but don't want to neglect something either. One of my mottos is "if it ain't broke, don't fix it", but I try to balance that with good attention to PM. Any thoughts or words of advice in this area? Thanks.
