Background info: Had a blown head gasket and a mechanic used a sealant on it to patch it up. Car went from not turning on to running ok
Problem: at idle the engine creaks. It isn’t a ticking or knocking but definitely more of a creaking sound. Can’t figure out if this is safe for the car to be driven and what could be causing it.
I have a video of the sound if anyone feels confident they might be able to guess what’s going wrong. Potentially a head gasket that was partially fixed maybe??
