1st oil change @ dealer-interesting convo. Warning: tick content

[accel]

It's got to be cavitation. But it sounds like a chain flopping against a metal pan.
2019 GT with 12500km on the car. This year I did my seasonal year end-of-year oil change after 4500km. Oil in the pan was Penzoil Ultra Platinum Synthetic 10W30 that contained 1 bottle of Ceratec that was added back in April when the car came out of hibernation.

Drove it 4500km this year and had no abnormal engine noise that I could tell.
Old oil and Ceratec was drained and replaced with fresh PUP 10W30 oil. Oil filter was filled with fresh PUP oil before starting.

1st cold start out in the driveway with fresh no Ceratec in the oil. Ambient temperature around 12 degrees C.
I heard this random loud clacking noise when I got out of the car. This is what it sounded like:



The sound was loudest under the passenger side. Opening the hood, I could tell the noise was not from the valve cover area.
After 5 minutes idling the noise seemed to quiet down slightly and became synchronous with the other engine sounds but still loud:



And lastly still noisy a few more minutes later after pulling into the garage. The engine noise can be heard pretty much everywhere reverberating off the floor and walls:


In the spring I am going to record the same video. Then add Ceratec to the oil to compare.
The noise is a bit unnerving but the car runs and pulls great. No oil consumption at all that I can measure. I really don't know what to think of this except keep driving until something bad happens.

Before your post I had this theory that if ceratec was added to oil well before the oil change (so that it has time to spresd and buildup), then it would protect the engine during oil change and thus prevent engine tick.

I add 150ml of ceratec to each oil change preventatively.

I do add the Ceratec (1 bottle). But I do it in the spring when I can drive the car. The oil change is done in the fall so the engine is not sitting all winter with old oil. I don't add the Ceratec until spring because I feel it would just sink to the bottom of the oil pan after the oil change.

My engine got tick twice and I got short block replaced twice in pre tsb times. Second block ticked just like yours right after oil change.

Not taking any risks with my current block. Added cerstec to it shortly after the replacement.

I'm adding ceratec but I'm also concerned with sediments. 150ml worked for me through several oil changes. One time I even used just 75ml. No tick, but then I topped to 150ml later. Will try 100ml next time.

Besides prefilling the filter I also prime the engine with oil pressute and only then start it. Ceratec - I add it to jugs and shake well before the oil change. It actually takes time to build that pressure by engine starter only. I'd estimate 10-15 seconds.

I still have yet to see an example of a failure due to the bbq/typewriter tick.

As long as neither the cause nor the effect of the tick is not known/made public, how would anyone know that one or more failures are not related to it?

 

[Zent]

wait so are you guys saying cos of the tick issue its best to use full synthetic in these cars?

No cause/or the effect, that is incorrect there is plenty of public information and post with regards to this normality.

One can choose to accept the facts as they are, enjoy the machine. Or have regrets, dislike the car, making the payments .
