Title: I30 2008 1.6crdi knocking engine
Post by: rob_danny on June 15, 2020, 17:20:59

Hi all
Have a problem with a noisy engine
It is also unstable when idle
Never had a I4 diesel car before, only I6 and they were smooth
The car itself runs and drives sweet, acceleration is good
Serviced every 5k miles at least in my ownership (15k miles)
Had the problem before but it wasn't that noisy
Only can be heard without the oil cap
Here's the video

Was thinking, hydraulic lifters? Bit too noisy imo
Hopefully not the bottom end

Thanks for any advice

I was going to suggest taking the engine cover on and trying to listen injectors via stethoscope (or a screwdriver). But opening the cap really made it audible. Does the engine have right oil in it? Sounds a bit like something in the cam, valve, lifter section.

Hi
Yes the oil's been changed last week along with the filter.
I'm planning on taking the cover off tomorrow to see what's what then...

I was just thinking about the oil viscosity. Someone put 0w-30 once to engine which was meant to run 5w-30 or 10w-30 oil. Lifters started to make noise as the oil was too runny.

Sounds quite similar to mine both with and without fuel cap. I never did get to the bottom of it .  :crazy1:
After my engine warms up tho it’s mostly not to noticeable(unless I’m driving next to a cement wall then I can here ticking  :crazy2:)

Keen to follow this thread . (I use 5w-30 aswell)
