Hi, I bought my 2004 156 JTS 2.0 Manual sedan about 2 years ago with 133000km on the clock.
In the first month I ran the car without oil for about 4 days (dry dipstick) as I didn't realise how much oil the car used. I subsequently measured the oil consumption at 1litre/1800km. I suspect the previous owner may have had a similar incident, but didn't tell me.
I didn't notice any damage, thought I was imagining a very slight drop in power, but not really noticeable.
I've added about 50k in 2 years with no real problems.
A few months ago I started hearing s light metalic grinding noise which I thought may be a pulley bearing that's busy wearing.
Then 2 days ago an engine noise started to become quite loud. Not sure if it's related to the first noise. It sounds as if its coming from the cambelt side of the engine and higher up.
Someone looked at it today but said it could be a number of things, but he suspects it's someting in the head. I agree, I don't know if its a valve or what...
I've uploaded a video clip here https://www.youtube.com/watch?v=pqLwycZjxdc
Has anyone heard this noise? The real life noise is very loud compared to the normal engine noise, it also has another element than a pure knocking sound (grinding?)
Likely course of action? I can't pay someone thousands, I'll have to fix it myself.
