My 6.2 has this noise when it's cold, And goes away once it's warmed up.

the direct injection also makes a noticeable ticking noise

Oops, I just realized this is the 2015+ section, so my noise surely is different from what you may be hearing in your newer L86. Sorry about that

The direct injection will take a moment more to turn the engine over than previous 6.2. The fuel pressure has to build up to something fierce. The DI also makes it’s own sound.

The tick tick on the 6.2 on our 08 was a leaky ex mani gasket at #7 right against the firewall on the driver side. It had a broken mani bolt back there too. The GMC dealer flat out closed their eyes to it for FOUR years and concealed the code it triggered. Bastards!

It took a crack diesel Indy mechanic a few attempts to get that bolt out w/o pulling the head just today.

Fuel injectors

people who try to buy your car and claim it's making noise to try and get a lower price.

My 19 has a VERY notable tick. I assume its the injectors as it doesn't change throughout the temp range. I think its normal
