Now I see why so many used Corvettes are for sale and they are still trying to get 50 and $60,000 for those used corvettes

To clear the brake codes, push the start button without stepping on the brake petal to power up the car. Do not start the engine. Then press firmly down on the brake pedal for 20-30 seconds. You will hear clicking noise during this process. When the clicking stops you can start the car and the brakes will be reset , the codes cleared and warning lights gone.

Did the thermal plates and blanket help much? For the price, would you say its worth it?

This is cool wish someone would make something like this for cable driven

Lol how you seal between zylinderheads and the plate it's really strange

My GM service team changed the fluid and after a track day went to limp mode. They changed the entire brake booster system and programmed it and 2 days later same problem. Now GM is saying it’s because I have girodisc rotors and carbotech pads and I gave to put OEM parts back on. What have they done wrong?

I bought a 1993 Spartan to with 32,000 original miles I love it everything works a year and a half later I had to put a water pump. Hi Mechanic got one online put it in works awesome wouldn’t sell it for nothing only 350 were made it is definitely a collector car and you can name your own price.

What is your shop contact info?????

This vid just made a lot of Z51 brake swaps WORTHLESS.... THANKS for the heads up.

I’m really thinking about buying a c6z 2008-2013. I’m not an expert on motors, can anyone tell me what all exactly I need to buy to replace in the engine to prevent a valve from dropping. Also what’s the price estimate on how much it’ll be to upgrade everything?

There should have been a class action lawsuit against GM for this failure. There isn't any reason the customer should have to pick up the bill on this!

Great video man. I am sorry, but I played the Benny Hill theme on the quiet parts of the engine tear down. lol

so which software on tds do you need? tech2 win or light duty global diag (gds2)?

Gm has a history of not righting wrongs and this is no different. They should've recalled these values guides under warranty.

Hi I just want to bring my c8 to change brake fluid what's the address or phone number I'm an dallas Fort Worth

Thank you for this informative video, and you are correct that there is an information vacuum about this online. I was going to swap out my calipers (from black to yellow) on my 23 C8 using the usual brake bleeding procedures. You have saved me from making the serious mistake of trying to do this without the exact tools.

Does Texas speed give you any guarantee that if your engine blows in the same manner with these new valve guides

Must be pretty embarrassing putting your name on it and that’s gonna blow

I just can’t take anyone with a Tesla jacket on seriously 🤷🏼‍♂️

So even fully built this zo6 is still going to have valve issues ?

Where did u learn to do this?

2022 update in the future? Still have the 13?

So zr1s also have this issue?

You shouldn't be putting out videos on technical issues such as clearances you haven't got a clue.

What will cause a valve to drop?

Your the only person I’ve seen has a z07 velocity yellow corvette. I would love to see a full video on the z06 in detail

I have a question for you, currently trying to install these on my 2015 Z06. At 6:12 into your video it appears you place some sort of black "cap" on the opening there. Can you elaborate what that is and if it's 100% required? I bought my plates from someone and all they came with was the bolts and plates, not sure if this was missing or needed separately. Appreciate your feedback!

Did you say at the start of the video that the person who dropped a valve was a c6 zr1 ? I thought it was a zo6 issue ?

GM tried to save too much money again.

Why Does everyone Keep saying Dropping A Valve? These Valves Are Breaking Or separating , Dropping Involves The Keepers Or Retainers Failing Or Coming Loose And the valve Falling Into the Motor. That Is Not What's happening. The Valve Stem Is breaking. Big Difference, At Least This guy Is saying Why and what. Thank you For That.

Thank you for not adding music👍👍👍👍👍👍👍👍👍you don’t check the clearance that way. Take springs off remove seals clean oil off then you can check.

Im retired GM service tech. GM cant get the centerline of the seat/guided the same? The valve head breaks off? Junk valves? Worn guides? Are they worn in an oval shape or are the worn round? Im gona get some guff over this...bring it....worn guides are from junk springs...springs where the top and the bottom are not parallel. It has nothing to do with the tip of the roller rocker not being in the center of the valve stem or oem stamped steel rockers...Big block chev has valves that are angled in 2 directions. Have you ever heard anybody say they needed roller rockers to keep the guides from wearing out....i have messed with a couple sets of heads, this set was on a L88 427 i bought....ran it in my boat and it ran fine ruclips.net/video/11eXlFkZekM/видео.html Nothing more than bad springs.....Easy to prove, get a head with bad guides...put the spring on the valve, put the rocker are on and figure out how to use the pushrod to get the valve off the seat. Good spring, valve will move around with your pinky finger, bad spring and it will be pushed to one side, really bad spring and you will need a tool to move it. Ti exhaust valve raise redline? That aint gona happen, ignition has a rev limiter, the intake valve is bigger/heavier than exhaust, it will be the first to float....and round up a dyno sheet for your motor....see where peak hp is? You need to shist a few hundred rpm past that...or less..short shif is always best

Did you also measure 90 deg from the one shown in video? I would think that tangent in line with the rocker shaft would show more wear since maybe the rocker is pushing out slightly (towards outside of car) while also pushing down. (The direction shown at 10:15)

You are fixing a year that didn't have the problem. You range js acceptable and you did t measure properly. Should have had the springs removed. But hell, nothing wrong with a nice ahead job.

You said you had nine to ten thousands on the intake exhaust but you never or I didn't catch, what the measurement was supposed to be. also, even with that side play I don't understand why the retainer didn't hold the valve in place...? In order for the valve to drop either have to break it or the retainer has to come loose. Which is happening?

John, nice presentation. A couple of thoughts. First, do you have a "slow-mo" version of the head removal. It was difficult to pause the video fast enough to see what you were doing, so definitely slow motion would be great. Second, having watched several head jobs that check the guides, I noticed you measured at the top of the stem and not at the guide itself. I'm really not sure who is right about this. Where did you get your information to test the distance at the top of the stem and not at the guide. Thanks John for the video!

This is why I own an nsx r and not a corvette, Honda would have done a recall if they had this issue in their cars! GM is a terrible and greedy company

What year was your buddies ZR1?

Nice info on the auto-blip. As for the TPMS sensors, if possible get a different set of wheels/tires without TPMS for track days. Those things losing air under severe stress is fairly common. It happened to me with my 2012 Mustang GT. I got lucky, a local tire shop happened to be open and they replaced it for me.

Awesome video. Yes, some of it may be a good advertisement for Texas Speed, but so be it. I've been around this stuff a long time. I was a Tool & Diemaker for 40+ years. If I do say so myself, I am very impressed with Texas Speed. I knew they did good work, but didn't know they ground their own cams. I see cam grinder is a Landis. I ran a Landis O.D. grinder for almost 20 years that accepted pieces up to 8 feet long. They were based in Pa. at one time. Don't know where they are now, maybe still Pa.? Anyway, I see Haas machinery also. All really good equipment. Looks like you went to the right place. These LS7s are great motors, but ticking time bombs until heads are redone.....

Unless that insulation blanket was foil faced on both sides, you put it on upside down. The foil needs no face down towards the heat source. did you see any results in blower/IAT2 temps? Would you do it again?

Hi bud, does the LS7 engine require lash caps and if so on which rocker do you install the lash caps on? All the rockers or just the intake side or exhaust side?????

would it work on a 2001 mustang cobra? im very interested!! -p3t3r

What's more expensive, an extended warranty or this?

Great video but I'm Not gonna lie , never thought I'd see a 7.0 liter LS7 Vette owner who is wearing a Tesla jacket. What's next you're going to tell your car doesn't have any cats? ;)

Excellent information Thanks

LS engines are nice, but costly! I guess that's why I'm still using a big block Chevy. 🤣

How did it run??

Did you need to modify the hood since it sits higher now?
