Long story short, it had lifter tick day 1. Since i hated the dealer I got mine at i went to 2 other who claimed not to hear it. It was obvious folks. Dealer took 3 months to fix it and when I got it back they started ticking the next day. So I bring it back up there and they are trying to tell me that this is caused by my Haltech intake and the MAF.
What should I do? I'm getting very close to the end of my warranty and these mouth breathers won't fix my ish. Meanwhile, I'm still waiting on my reimbursement for the 3 months worth of rental cars from the first repair because this is still an open issue.

Is it possible you are hearing the direct injectors? They are loud and sound like lifter noise.
no. I'm familiar with the sound. Plus they already admitted it when they "fixed" it the first time. I bet he tested one side, found the bad lifters and didn't bother with the other side.
so? unless they have voided your warranty, return it to stock and take it back.
they are just going to look at me and say, "we know you just changed it and we're still not fixing it". Unless you think Lois Lane is running things there i doubt that will work.

They might or might not. The diagnostic procedures are written in a way that counts on the car being configured as it was designed from the factory. And, in some cased, a modification actually prevents the tech from completing the procedures as written. So, it could be that - they are running diagnostics and getting unexpected results caused by the mods, even if those mods are not actually causing the problem. GM cannot and does not run tests to validate results for all possible aftermarket mods that could be installed.

I wonder what possible diagnosis or procedure could result in mechanical lifters malfunctioning being caused by a MAF but whatever. If the 2nd tech says the same thing or won't fix the obvious problem. I'll put the factory box back on and go to another dealer.

I don't know. I assume you don't have a code set.
The manual is 7000 pages, the majority of it consisting of procedures that are called for by specific codes, and then repair procedures that are called out depending on the results of the diagnostic procedures. Without a code, there are some general procedures they might follow.Engine related procedures may start with verifying proper function of basic engine components. Done by verifying that sensor values are within specified limits.
I do not know if thats what is happening, and I get your point that the mods you made should not cause a lifter issue. But it could still cause out of range sensor values and hinder diagnosis.
You said they fixed one side. What did they do to fix it?

they replace 2 cam shafts and the matching set of lifters. So they left the others completely alone. I really should have thrown the key back at the manager when i picked it up. Long story short, i when i originally went to pick it up after buying it they said I couldn't actually get it because they had to have a special tech inspect it first. F-ing dumb *** didn't catch this because it was doing it day one.
worst part of it all is i bought this car new because I was tired of working on older sports cars and I just wanted something awesome with a warranty. So much for that.

so? Make them tell you that. Then elevate the case. Not sure what answer you are looking for, unless you just want to vent.

An LT2 only has one camshaft, that's an engine out replacement. Are you saying they removed your engine for the work and you didn't know it? Lifters are hydraulic, if there is oil pumping to them they work.

I don't know what they did to replace them but yeah, apparently they weren't working that great because they tore up the cams and a couple of valves needed to be replaced as well.

You keep saying cams like there's more than one, there only one, it's a pushrod engine. Valves is a heads off repair, so not only did they pull the engine, they also pulled the heads and the cam???? THAT much work would certainly be on your service ticket they gave you when the work was done. If your engine had a destroyed cam, damaged valves and failed lifters, you complaining about a lifter tick is like asking for a Band-Aid for a shaving nick when your arm had been cut off.
