Hi,
Ticking usually is from a lifter. Does the sound seem to come from the top of the engine? You could have good compression if the valve lash is too large. Also, that would cause ticking.
Additionally, do you know if the valve lifter oil filter was replaced? It could be partially blocked lowering pressure to the lifters. It is mounted under the oil pressure sensor and under the intake manifold. See pic 1.
Let me know. Also, if possible, record the engine making the noise and upload it for me to hear.
Take care,
Joe
