Clacky Om606 - ho55 - 04-17-2017
Since i got my donor motor fired up, its been a bit clacky/knocky on the rear end on idle but smooths out over 1500 rpm.
I dont think it was this way in the donor car, but that did have better sound insulation.
Recently i did a diesel purge, and while it was running on the purge fluid the knocking was gone, but after putting back on diesel it was back.
Does this give any clues to anybody?
I have not done any timing checks or checked the injectors as yet. Its a electronic ECU.

Could be bad injector or dirt gone to injector, they can keep pretty bad noises.

Open lines one by one to diagnose if its injection related. Could be tappet related or even valve...
If its injector, have them cleanened and repoped. Delivery valves cleaned and holder washers and O rings done.
If its tappet is a lot more dirty and time expensive. Valve is even worst .

Video?
I would say tappets make clacky idle if the injectors & DVs are good, and disappears with anything over 1k rpms. But purge shouldn't make a difference to the tappets of course..
