Check out these new boots after 10 minutes of driving!



I drove around last night in the dark normal, no WOT, and burning did not get worse and headers were not glowing. I bet WOT is what does that.
The GOOD news is it is only the boot on #2 and a little on boot #4. All other 6 boots look fine.
Maybe #2 and 4 has an injector or fuel rail feed issue?

I put a sock over #2, wiped the ash off #4, and will see today if it burns more or not.


No WOT for me!

My fuel trims dump fuel on that side at idle. Cruising they even out. Does that mean anything to anyone? Like at idle that side is 140's - cruising it is 126-130's: http://www.cdntechnologies.com/camar...afterwires.zip

 

i have them thermal covers on all plugs. could be a bad injector, could be a valve spring

 

how bout you fix your valve cover leak.

 

Looks like your front header bolt on the #2 primary is backing out. Get that tightened up and reset the PCM before you try to combat any fueling issues, as exhaust leaks can affect oxygen sensor readings (and thus affect BLMs on that bank).

That said, I'd probably pull all of the spark plugs on that bank and see how the electrodes look -- see if all cylinders are running lean/hot on that bank, or just the front two cylinders.

I don't have datamaster on this computer to check your logfile, but if you get that header bolt torqued up and the header gasket isn't leaking, I'd then suspect fuel injectors, vacuum leaks, the Bank 2 oxygen sensor/harness, or maladjusted rockers.

 

Thanks everyone
It was the loose header bolts. I never noticed them before. It would only leak at WOT and burn the boot then. All the other boots are still OK it's just the ones I found loose bolts on that burned. Since tightening all is fine.

Thank you!
