Default hydraulic lifters (tappet) diagnosis - 05-16-2017, 06:16 AM

Hi guys,

So im always hearing metallic rattling noise coming from the engine at idle, i have my valve cover off to tap and plug the pcv system.

i was wondering if theres anyway to check which hydraulic lifters are damaged? or if there a way i can clean them?

would appreciate some info

I wouldn't plug your pcv valve imo. And are you sure it's not injectors? When's the last time you changed oil? N54 motors generally make some lifter noise.

I plugged the pcv intake slots as i have an external pcv system. The car is running fine so i don't think its injectors. But as i have it all open i thought it's a good time to replace the hydraulic lifters...

he was saying that the injectors tick. Not that they're broken, just loud. Direct injection isn't quiet.
