1HDT ticking, knocking? (1 Viewer)

[ivansolis10]

Hey! Ive come again asking for wisdom from this awesome community!

I have a 1993 80 series with a 1HDT engine

im getting frustrated with a ticking or knocking sound im not sure at this point….
Some mechanics say might be valve, others say injectors and others say rods

- Engine was rebuilt 3 years ago
- Fuel Pump has been rebuilt
- Head was rebuilt (valves, shims, etc)
- I dont have any symptoms like loss of power or too much smoke
- car runs great
- even after the engine rebuilt i always felt that my engine sounded much louder than other 1hdts
- Injectors dont have denso nozzles
- the sound never changes, cold start, warm, idle, highway drive it always sounds the same
- the sound is rhytmic with the engine revs and injection

Have you checked valve clearances yourself? Start there - easy task to do and least invasive.
