I have heard and seen stock TBSS break stock valve springs but havet heard of them having push rod problems. Of course that doesnt mean it cant be a push rod but I would bet on thats not it.

Yes I did a CASE relearn with new PCM as I was instructed to do so.

Will a datalog show a valve train issue?

It can if the right things are data logged, with EFI scan tool you can data log around 25 different parameters and record them. Its alot easier to data log something and record it and play it back frame by frame to see what is not right.

What did you use to do the crank re-learn? Are you 100% sure it worked? I have had to try several times before because with EFI Live you have to meet certain parameters before the re-learn will work. When you do it with efi live you are 100% sure it worked because the vehicle will cut off for a second.

It was done with a genysis scanner. And yes it worked.

hope the PCM doesnt magically fix it, that'll be an expensive "mask" fix......

like a bad ground a tech found but had 5-6hrs diag time in the vehicle so he gives the "its the xxx part and cost $XXX to fix"...... just to make some dough.

Well....they called. He said he can't figure it out. Come get the truck no charge.

WTF? I asked if they investigated valvespring tensions and pushrods and the like.

NOPE. He's tired of chasing a gremlin he says.

WTF do I do now?

Get it home and check the push rods on your own.

Gonna get up with Neil and datalog it first....

Problem with pulling it apart myself is that right now it's my DD. Don't know that in the 4 hours a day I get at home that I'm not sleeping, that I can get it all apart and back together in that time.

Might just go to Crews on Friday and drop it off.

That's pretty weak for a dealership...

Yeah, that is fucked up.

Even worse, he called my sister (former employee of RH Chevy, now Hyundai) and informed her of what was going on. That I had written some things on a forum that "were not very nice" and he has printed them all.

I just reread this whole thread and don't see anything "not-nice" anywhere.

Chris the service manager, and Kelly the technician, if you read this, thanks for your help.

To whomever informed them of this thread, thanks. I hope I find out who you are.

Do what!!

Well, this will show you that you can't say anything around here (Charleston) pertaining to performance cars without it getting around. Everyone is in bed together in this town. It's one big circle jerk. If they haven't worked for a shop or dealer at one time, they know someone who does. That's just how it goes.

Sorry for your frustrations. Let us know if we can help.

Already had a PM asking me if I was the one that said anything. I am kind of glad I didn't make it over to hendrick this past weekend as I had originally offered.

Keep in mind that 2-3 other Hendrick employees are registered members here.

That's the question. Thanks for replying matt. Was just curious if it came up in your conversation, no need to get all defensive it was only a question. If u didn't talk to him then it couldn't have come up.

Thanks for all you guy's help, wish this would have ended a better way.

I learned that lesson too. Don't make ANY comments about someplace when your car is in their hands... same thing with the people who handle your food...

Should see what I did to your block.

IS dats why its so slow???:mrgreen:
