308 ep6 5fw missfire.

[Cristian]

Hi there.
I have a 308 2010 ep6 5fw with 80000 ks.
It has a cylinder 3 missfire that only happens when engine is hot.
I have done all obvious sparks plugs coils injectors. I had it diagnosed by Auto electrician and everything electrical seems good.
The issue has been narrowed down to mechanical.
Can anyone send me the intake camshaft procedure to dismantling the spring and parts attached on the picture I have put up.
Any advice on what else I could try is welcomed.

You may get an idea from this video but I found it hard to understand and a bit long winded so I haven't watched it all, but it may help!!

At that distance it might be the timing chain is worn, our 2010 1.4 vti C3 needed one at 50k miles and was giving an error code suggesting a timing fault.

Mine is a missfire on cylinder 3 that only happens when engine is hot and in iddle.
Non electronic issue it seems but a mechanical one
