That would be one or both of the 2 feeding and draining the turbo and they would have taken them off and put back on when they did the head work. It should be on them if it wasn't leaking before the head repair.

You are right to be frustrated! These mechanics are idiots!
I am still pondering the root cause of your problem. What NGK plugs exactly were you running? Who recommended them? A wrong plug could have caused knocking and the valve damage.

NGK SIKR9A7 SPARK PLUG SET (OEM SPARK PLUGS 1.4L MAIR TURBO)
These are the plugs that I bought from EuroCompulsion.

The NGK's are OEM. FCA just stick them in a MOPAR branded box and double the price.

So Alison, what you have read, should my warranty have been voided with the parts added?

Hi there, Allison of Fiat Cares. Welcome to the thread.

In amplification of SteveWy's question, can you tell us why an OEM equivalent part - the GFB DV+ - was used to deny his warranty, when it's routinely recommended by a number of Fiat dealers, and based on that fact, hundreds of owners here have installed it as a replacement for a failing original part?

Thanks!

the tune would have voided his warranty even if he hadn't installed the non-mopar-branded spark plugs (even though they are identical to the mopar-branded ones) as well as the dv+.

Yeah if you are running an aftermarket tune I'd fully expect to say goodbye to warranty.

Same with anything that you take beyond spec outside manufacturer claims. Sucks but there is always risk.

Hope you get some resolution. Wouldn't expect fiat to agree to anything on an open forum!

Are you guys aware of the The Magnuson-Moss Warranty Act? A warranty can not be voided for modifications unless it can be PROVEN that those mods caused the needed repairs. Even then the warranty is not voided just the coverage for that specific repair is denied. Some of you should speak with a lawyer.

This is correct. Dealership told me this too when I asked about making changes. I'm in Canada but warranty should be the same throughout North America.

The exhaust valves burn because of excessive EGTs. What really happens is that the cylinder gets too hot, the heat hurts the guide and seals and finally the heat warps the valve. Now, you have a valve that is sticking open because of deformation and ta da, the valve starts to take damage as it is now exposed to combustion on the “back side” of the valve.

I have one or two exhaust valves that are hurt as I discovered this during a leak down. A number of us with 500s have had the same failure but we’ve run piggybacks and an EC tune.

My EGTs were always maxed out with my EC tune. They range from 600-750 without meth on my Tork tune, and rarely hit 700+ even with my max power meth tune.

FYI, you might want to back off on the pops and bangs.

Can you explain this statement somewhat? Are you saying that your 500 w/ EC tune reached the allowable max temperature? How much is that allowable? Are you also saying that the Tork tune exhibits lower temperatures? Is it because of the tune or the methanol?
My car with stock factory tune reaches 800 C (1500 F) in just a couple of hard 3rd-gear pulls.

This is why the 500 Madness tune goes to full rich at 5000 rpm--to cool the cylinders. And max boost is limited to something like 20 or 30 seconds before it goes back to stock tune for a given period of time. The stock cooling system is just not set up for much higher horsepower than stock. The tune is really just an 'overboost' for a short period of time but it's great to do a roll on with some guy on the interstate or blitz an on ramp. And, in the country, it can work almost continuously as you're on and off the gas frequently.

This leads me to questions concerning how the Chipbox deals with the fueling issue. When I bumped up the boost in my Saab 9000 turbo significantly we changed the injectors to deliver more fuel to cool the pistons and cylinders. Never had any issues with that set up. Anyone have any information from Seletron on this?
