Thanks again guys, but I can't take the credit.

There were many before me, who made similar posts, and during a time when I was even denying that the problem was as big as it was.

But after awhile, it became obvious to anyone following this matter, that it was, indeed a problem. Updates attributed to GM themselves seem to me to indicated as much.

Those ahead of me on this matter, may or may not have been as vocal as myself, but they paved the way.

Like the rest of you.....I'm just glad that there even is a fix, or more accurately, a means of effective protection, against a $15K bill, for those of us out of warranty for one reason or another. Be that reason time, mileage, mods or tracking.

Think about it. This problem would be a whole lot worse, if there were no known method to mitigate it, and no known way for owners to protect themselves.

Yes, it is expensive. It takes some automotive skill to do. But it apparently works very well.

Finally, I'm thankful for this forum, and the vendors on our forum, and off, who can offer an effective manner for dealing with the valve issues of the LS7.

Thanks to it, and them, this issue will no longer have the "advantage" of consistently catching us off guard, and without having the information and opportunity to take steps to protect ourselves.

So you can add me to the list now. Bronze guides, ss exhaust valves, ported stock heads.

I did not care if my stock guides "looked good" or had wear within spec, I wanted to be protected.

It's on.

Dirty Howie

Alright Ricky my new heads just got torqued down !!!!!

Add me to the list.

Pics/Post later this weekend.

Done.

And the brake fluid leak?

Dirty Howie

ABS BLock leaking They have some service port on them and cannot be fixed only replaced. That part is not available today.

Found my PS pump leaking also. We are waiting for that and will replace it today.

CMS is doing an asskicking jog

Any one check their geometry that is where the rocker strikes the valve stem.
The hole for the guides could be the issue, that maybe the missed machined that GM hasn't named. New guides will wear as well if this is the issue.

good question. are there specs/procedures on what to check for exactly?

new guides will indeed wear even on "perfect" heads, but having new bronze guides + solid stainless steel valves seems a bit more stout than the stock 2-piece hollow setup.

ABS block. That's what I was afraid of.

'06 Quicksilver Z06

Yes, I did and posted the results complete with pics long before that thread jumped the shark.

My witness marks were fine.

Dirty Howie

So what do you know about this?

I don't understand why this cant be patched up in some way? It functions fine.


DH

PITA.

Anytime that block is involved, I believe you need a Tech 2 to bleed the brakes afterward.

Sharpie coloring applied


Rocker arm shown, no brown half moon "skid marks" indicating "bad juju".


My witness mark on my WCCH heads.

For that exact reason, I will go aftermarket heads if my guides are worn.

Dirty Howie

Your car was covered. I pulled it back a bit and took a picture for you. I will post it in my new thread that I will start working on tonight.

Thanks for calling this to my attention msd127.

Also, I added SS MPSTR as his car is at CMS now having his new WCCH heads installed.

Congrats SS MPSTR.
