Hi, i have a 94 Toyota Hilux ln86 2wd ute with the 2.8l diesel naturally aspirated and the engine shakes on idle. it runs great and has heaps of power while driving. When you go to start and stop the engine, the exhaust pipe hits the chassis rail and will eventual over time crack the exhaust. i have put new engine and gearbox mounts (genuine Toyota) in the vehicle but it still does it. the engine idle is set to 700rpm. I have even tried putting rubber mounts on top of the engine with support bars to try and stop the exhaust hitting but it doesn't help. The engine only has 150,000kms on it, doesn't burn/leak oil or use coolant. The fuel primer pump has been replaced thinking it might be sucking air but it wasn't (it holds pressure). Also put new glow plugs in it. It doesn't matter if the engine is hot or cold, it still does it. If anyone has had this problem or knows what it might be, that would be great. Thanks, Ryan.
