thats why i asked - i have a
2qm20 on my
boat and it sounds like theres a jackhammer in the big end when i start it, settles down to gentle carcrash as it warms up a bit - these old 2 cyl diesels sound awful but - they go fine. If it started to make a LOT more
noise, I'd say worry, but if it just seems really loud but goes ok it probably is. Remember its a
compression ignition engine - no glow plugs, so seriously high
compression heads, but they are designed to run like this. If you get a chance to get someone trustworthy with experience of these engines to have a listen to it, that might be worth your while, hopefully just to set your mind at ease.
