Escort Bj96 1.3L Hydros?

Hey, I’ve had an Essi tournament with a small 1,3l EFI engine for about 2 months. The engine sounds like a little trecker since the first day… no matter if it’s cold or warm, it’s always clacking, only if it rolls and I don’t give a gas, it’s very quiet. I had first tapped on the hydro plunger, so it was at least with my E30 back then. I’m absolutely not sure because I have no experience with Ford! Would be great again if you could help me! Thanks and mfG cd
