    Small update:
    Pulled in togehter without the filterbox, tried a PVC pipe against the cylinderheads. But dident work for me, dident hear any better. Think i need to buy a stehoscope for this.
    Made another video, pulled my phone. a few cm from the cylinderheads and moved it back an forward slowly. One thing i noticed today is that the ticking is very irregulary. Can hear that in the video also.

    Hope you staying safe out there in this crazy world.

    You should check the valve lash to rule it out. I know its a pain.

    Ya, I'm still thinking it sounds like a loose valve tick.

    Update: So, i bought a stehoscope. Worked alot better. And yeah, the ticking sound is from what i call cylinder one. (closed to the front). Could hear it best if i put the stehoscope real close to the sparkplug. Gets lower and lower on 2, 3 and the lowest on 4 ofc.
    As i sad before, the owner is ensured me that they been rebuilt. (in no way a garantee but).
    Can it be oil relateded?
    Im using mobil syntetic 10-30. Was thinking of adding some oil additive. But might be pointless?

    I know you said before to measure the valuves. But honestly dont have the knowlegde, so need to have a shop look at it, and will be costly, so im just wanna make sure its nothing else that i can check myself first
