My forged FSI engine EA113 rattles a lot (video included)

(1/1)

Ucefkh:
Hello guys,

My mk5 GTI BPY engine 2007 has been rebuilt and almost a year now, i had this rattling noise from the top of the engine around the cams..



Everything is forged besides the cams and rocker arms(they were not changed) so i have been struggling to locate or find cause of this rattling noise!



Please check the videos(one is a cold start and second is a warm one after a drive!



Cold start: New video by Youssef KH



Warm engine after a good drive:

Please help!



Should I change the cams? Rocker arms? Lifters?

RasmusT:
Sounds like the chain rattling..

Ucefkh:
New chain! New belt, timing checked with the metal piece you do timing from ecs tuning! All checks out

What would it be?
