4th gen head gaskets are starting to show up in large numbers...

Read the thread. Thanks!

So what would you recommend?
Letting a dealership do it for $4800?

Also, there are many Gasket Master locations, or so they say.... Maybe they all don't cuss at dissatisfied customers..

I like that they use the Felpro, the dealer probably doesn't. I wonder if I asked for that particular HG gasket they would use it?
Probably not....
What I don't understand with these quickie HG replacements is,, Why are they not resurfacing the head? Why not disassemble the valves, clean every thing, at least lap the valves and install fresh valve stem seals?

Same with a dealership repair. My friend said they could have it done in a 2 days. I suspect they are not doing anything to the head other than wipe down the gasket surface???

 

Just found this YT short from Gasket Masters on Gen4's.
You can see that dealio in the block to 'even out the thermal blah,blah of the cylinder walls'.
But that doesn't help the HG, apparently.

If this comment sounds like an excuse, maybe someone should ask GMs what they think and what they are seeing. As stated at the end of the video posted by the OP, well just take a look see here and now

What's the newest Gen 4 they've gotten with a leaky gasket issue? And was it a daily driver, uber, taxi or something else like a courier service ?

Knowin they're providing their content keeps my eyes open.

 

I’m not convinced gen 4 has a head gasket issue yet.
I am convinced early years have had some exhaust heat exchanger leaks
