the shop and tuners name will not be given ever

 

ouch that really sucks bro, did you sign a waiver?

 

This is every car builders worst nightmare.

 

i tune mostly everyday of my life and i cant understand why people spend 2 to 3 hours on a dyno with one car unless they are having problems. i can tune a car to 450whp in less than 7 runs and never even have touched the cam gears. the fact that this happened is a no no. he accepted liability you should take what you can get. i think if the tuner made a 100% mistake he should cover some if not all of the $$$. i would start looking @ another tuner someone who knows what they are doing.

 

damn bro, sorry to hear that!

 

Did he know the specs of the motor prior to making those changes?

 

Is your block split at the outer wall? Shaky picture from cell phone so I can tell. If it truely came from the cam adjustment and the head was not milled or deck surface beyond a normal re-surface for gasket seating purposes then its totally a tuner issue. If you did not tell the tuner the head was milled several thousandsth and or the block decked then its partially your fault. That is some serious damage though either way. Post a better pic if you can.

 

thats what i was thinking, you should have told him how for he could move the cams, a little work on your end would have covered your *** completely

 

The Pistons were 9 to 1 compression. He new the specks on the motor. And yes He was having problem with the Boost controller. The Company that I purchased ECTUNE and the boost controller from overheated the PMW componets in the ECU whenn installing them so the tuner had to fix it. I singed a liabilitly wavier last time I went but not this time.

 

Really sad,hope it all works out for you.

 

The block is fine it just needs to be bored out. I am just upset that the head is trashed.

 

What size valves were they?

 

Get what u can out of it and then move on to a new shop!!

 

Stock size valves

 

When it broke, where were the cam gear settings?

There's a pretty good chance that it was not his fault.

 

I will look when I get off work. Thanks to everyones reply. This will help me alot. I just didnt want to call the shop being pissed, pointing blame and loosing a good realationship over something that was not the tuners fault.

 

A machinist once told me there is no such thing as a junk aluminum head. I dont know how true it is though.

I would be upset but as everyone said already make sure it was 100% his fault before you say something to him about it

 

What cams are you running???

 

Agreed.

 

If I have a motor blow up and its undenyably my fault our shop will rebuild the motor. But the reality is that alot of times stupid things happen that you can't control. I had a car with a brand new set of injectors where 1 injector was intermittantly leaning out at 26PSI.. After the first indication somthing was wrong ( melted off a ground strap on 1 spark plug) we sent the injectors out to get tested and they came back 100% ok.. We reinstalled them in a different order and marked them and the plug melting followed the number 1 injector.. We then told the customer he needed to buy another set of injectors since know we knew for sure it was a faulty injector.. but stuff like this happens.. the car would run perfectly fine around town and at lower boost levels with no issues, but once we got it up to about 26 PSI that one injector would go lean. Somtimes parts are just faulty. Just be 100% sure it was the tuners fault before you take any action. It always sucks but it happens, no ones perfect.

 

pro 1's

 

I always ask my customers how far I can adjust their cam gears. I didn't build the motor, so I would have no clue how far I can go until piston to valve contact, so they better know, or I won't adjust them. Better safe than sorry in my book. I feel really badly when motors let go on my dyno, so I try to make sure that it doesn't happen. Normally, problems during tuning result from poor assembly, or faulty components.

 

Real Pro 1's or are they just a stock regrind???

locash makes a very valid point here... You can have the best engine builder put an engine together, but if the parts are not top notch... Forget it! You might as well consider it a "Time Bomb".

 

****, my car went lean and torched a passage from head to sleeve. I was still asked to pay a small fee for the day and was own my own from there. But we were in an unknown territory and he had tuned my stuuff for years so I thought he was intitled to one screw up. For your case if the cams were set in a way that they would collide don't you think the problem would kinda surface the second you started it. What do your retainers look like. are any others starting to pull through.

 

Did u sign a waiver.. before tuning?
