Valve tick/ Lifter noise.... Gone?

[RCSignals]

............ after break-in oil ................

It has been stated before that there is no such thing as 'break-in oil' the cars leave the factory with Motorcraft 5W-20 oil.
If there was such a thing as break-in oil, 5,000 miles would be far too long for the first oil change to be recommend.

In the old days some people thought it was a good idea to use non-degergent oil as a 'break-in' oil, but even that is not a good idea, or good for an engine that will use detergent oil the rest of it's life.

can someone help me with my ticking noise

Can anybody help me with this problem. my oil is currently changed and this happened the last time i got an oil change but a lot worst. The last time it was coming from the driver side this time the passenger more so. The last time i fixed it buy taking a qt of oil out and adding a qt of lucas. I noticed 2 weeks ago while sitting in a drive thru that the temp gauge was past what it normally reads at (its was around the 3/4 mark comparing it to the gas hand) then as i took off it went down to the normal mark which is right around the middle. And also the check engine light is on throwing the 420 code. Can anybody tell me what might the problem be? Thanks

Temp gauge being that high means you have air in the coolant system and need to "Burp" it of the air. Search for burping.

That thump coming out of the engine is valve related. Either one is burnt which is common in the 7&8 cylinders which are the back 2 on the drivers side or perhaps it's something simple like a cam follower coming loose or fell off. The cam cover has to come off the investigate and since it's mechanical and not electrical that would explain the code 0420.
Good luck.
