Codes and Problems, engine ticking noise

SwedeZ

Hi. Youtube says "Video unavailable". I suppose you have marked it as "private" or removed it.

Was curious to listen to it, since I today noticed a ticking noise from my engine.

Just as in your case, it can only be heard at idle. Can't hear it when driving, and it also goes away at standstill when touching the accel pedal slightly to rev the engine.

Funny thing is (in my case at least) it's only present when the engine is warm. I don't hear it when cold.

This is what the engine sounds like when cold:



Pretty loud. Hoping it's just normal/common valvetrain noise?

And this is when it has warmed up (after a 20 minute in this video):



The ticking remind me of the infamous (and super common) Mustang BBQ tick that a lot of owners supposedly "solved" by adding liqui moly ceratec.

My engine was recently (500 miles ago) rebuilt completely due to a rod knock issue, so I cannot imagine it being oil pressure related (ie. gallery gasket). A brand new oil pump was even installed.

I wonder if my tick is just valvetrain-related (and harmless)? Lifter tick?

Or could it be from the "evap canister purge volume control solenoid valve" which can be pretty loud according to others here on the forums?
