5.7 manifold errosion

[FishStretcher]

If you are running non ethanol gas, then you are already taking pretty good care of it. I hear you can reprogram the 555 based systems. I don't know if that includes the TBI. The colder sensor or resistor in the wiring harness is a trick on older systems like that.

I suspect this would help. Maybe a fair amount. But at some point it is just cast iron in a condensing marine environment, so there will be a finite life. Which means I should look at mine, too.

edit: I wonder if edelbrock etec 170 heads would fix this. They are aluminum and supposed to be a replacement for the vortec heads. Something I am interested in, but haven't fully researched.

Bushwacker., Its an early EFI, throttle body system. Sensor in a cooler place is a good idea. I'll explore how to do that with my mechanic.


Raining today, it may be a while before I can get back to the boat.
