Texas Speed

[mikeyss]

Has anyone had trouble with the Texas Speed website. There is an option to plug in your VIN #, but when I do mine, it says it's invalid. So skipping that, I just put in my model year (09) and that it's a Tahoe. Now every product I look up is either for a 4.8 or a 5.3. I have a 6.2 so nothing that I'm looking at would be for me. Do I lie to it and say I have an 09 Escalade?

Here is why I am asking...

Yesterday I heard a NASTY tapping coming from the valve train. It sounded like the exhaust manifold gasket had just disappeared for 2 mins, or that noise you hear after an oil change first engine start. The engine was at normal temp, and I had turned it off for 2 mins to check the mail. When I restarted it, that's when the tapping happened. The noise has since disappeared and not come back...

I think it's either a lifter that got stuck and un-****** itself that quickly, or maybe a valve spring is on the way out. I'm not chancing anything and am replacing the valve train and installing headers while I have the top end apart. I have around 165k on it now.

I've chosen Texas Speed for the valve train stuff, but the site won't let me pick a Tahoe with the L9H 6.2.

I'm pretty sure Mike that all these LSs use the same valve springs. The 12589774/12706568 are shown as being for both the 5.3 and 6.0 and 6.2 motors. Sorry to hear about the motor, hopefully it was just a one time event.

If you have any doubts about what to buy give them a call their customer service is excellent.

What, no Colorado Speed in your area? C'mon man!

If you planned on doing the valve train work anyway, I see your point but I would not do all that just because of a sudden noise that has since disappeared. But if you need that problem to convince the wife it NEEDS to be done, go for it.

I had been planning on cam replacement, but was gonna wait to buy a house first. I'm kind of OCD, and hearing that horrible noise, I don't want to be caught with my pants down if there is a looming potential failure. It's my DD and the 2nd love of my life. Also, I never mentioned this.. but I have a husband..if you catch my drift. He is also a gear head and when I told him about the noise... His first words were... So we are upgrading the cam and valve train, right? We are on the same page!

 

[Dantheman1540]

Sounds to me you need to get a cam kit ordered ASAP! That lifter or spring could go any moment

Get used to searching with L92 and LS3 filters. Aside from yours having flex fuel, it's an L92 and aside from it being the truck variant, it's "basically" an LS3.

Call them, their customer service is top notch and the guys know what they're talking about. I have placed 5 orders from them and the only time I did one online was because I didn't have my debit card on me while I was on the phone.

25-LS3Camkit660 is the cam kit you want. It will give you drop downs to pick which cam you want, spring kit you want, oil pump etc. I would go ahead and replace the oil pump since the front cover will be off anyways. When I had mine apart doing everything I put the Melling High Volume 10296 pump in along with the pickup tube Orings and I'm running about 30psi hot idle, 40psi while driving, 60psi cold start on 192k mile L92.

CHE trunnion upgrade = Yes

VVT delete is up to you, I did it because of the cam I selected, not everyone has to though.

Think about getting a converter unless you want to keep the cam pretty mild. TSP sells a Circle D for our 6.2/6L80 combos and it works great.

The following is the most important part
No matter your options above. DO NOT get anything other than the following for lifters, trays, gaskets.
Lifters 12499225
Head Gasket 12610046
Trays 12595365

Those are the gmpp lifters and gaskets, not an oem ls7 setup or knockoff parts. But the good stuff. Trays are oem but are the only ones that should go in your engine.

Well, that was easy!

+1 for the parts recommendation, and my personal recommendation would be to get a VVT-friendly cam.

We went to test drive a nice 2016 GMC Yukon Denali. That was until we started the engine. Had a very noticable tapping sound that did not go away with a restart. We did not drive the vehicle and the salesman said they would check it out and let us know. Few days later the car was off their web site. Guessing they did not want to put a motor in it.

They probably shipped it off to auction!

Throw some 15w50 in it and send it to auction lol.

Now do not confuse the loud direct injection (fuel injection) with lifters it can sound very similar to the average consumer

 

[avalonandl]

Direct Inj. soundslike a sewing machine. A bad lifter is very distinct- has a loud single tap as opposed to a constant (x8) injector noise...

Don't do it! I had a 2014, 2015, 2015, and a 2017. They all had stupid issues. Read the forums. Too much to list. I gave up and traded my Denali 6.2 for a Mercedes and bought a 2013 Suburban LTZ as our second truck. So happy to be back in the LS truck. I have been a GM truck owner for over 30 years and have never seen more issues with any other platform than the 2014-2018. At the price point its just unacceptable.

Good luck
