Who has 6.2 and Does the 6.2 engine have a tick tick noise

[Jorge1313]

Have a question for all with 6.2 engine does it have a tick tick tick tick noise when one on mine now 2000k and has a sound tick tick not sure if the normal or not. Someone told me it same as vette engine it lubrication noise noise who know there stuff here.

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.

also with 2 million miles your doing pretty good..

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

My 07 Escalade ticked for the first few minutes. I was alwayes under the assumption it was piston slap.

Mine is a 6.2 and that ticking noise are your lifters. I got them all replaced by a local mechanic $4K

What year?

The newer 6.2 have direct injection. The injectors are much louder and the produce a "ticking" sound when they fire

Could also be lifters. Mine started ticking really loudly and I had to get the lifters replaced on a couple of cylinders. Cylinder deactivation strikes again.

It is similar to the corvette engine and it is the injectors, same noise as in the corvette. My corvette had "injector" noise with the stock injectors. Once we went forced induction (first supercharged, now twin turbo'd), who the hell could hear injectors over the forced induction and straight pipes (unmuffled but for the turbos)……….

If you are worried about lubrication and possible ticks as a result of low pressure, throw an oil pressure gauge on it. 200K miles wears things out.

Mine. 2018 year model

I'd bet injector noise. Its normal
