[N52dj]

I have a 2008 bmw 128i n52 automatic
Liquid Molly oil 5w30
This issue didn’t happen before the vc job, people r saying loose spark plugs

Just replaced valve cover and all seals
Spark plugs and coils w bosh
Pullies and belt/ Alternator
Oil filter housing gasket
New oil / filter

When starting now the engine seems to knock , I tried to attach a video
It does go away after driving about 5-10 mins
I’ve only started the car a handful of times since the vc job
