Engine Thumping

I finally got the thing running! After a head gasket, delivery valve o-rings, engine mounts, radiator flush, engine oil and filter change (Mobil 1 5-40 3 qt, Mobil delvac 1300 15-40 4 qt), oil spinedel o-rings, fuel filters, glow plugs, glow plug rely, and a bunch of minor things. Before starting it I filled the main filter with Power Service fuel conditioner. It took about 10 tries for 15 second intervals to get it started. (It was over 4 hours of time) It started and seemed ok once the idled smooth out.

Now it has a loud thumping and i can't figure where it is coming from. Or what it is. all I know it it does not sound good

Hope the video is ok, Kinda hard to see. I loosed all of the lines to the injectors from 1-4.

Thanks for any input

sounds like you have really tight valves, try adjusting them again.
Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?

Hydraulic cam followers on a 190D 2.2. No adjusting other than replacing the follower. My '84 had the same noise and I replaced a follower and the noise went away. Then again, I could be wrong and probably am.
