I recently posted about a tapping and was advised to check my ehxuast for leaks and it indeed was a leak. I have cracks and missing pieces in my header gaskets. I am about to buy heads and i want to know if its really a big deal to have them leaking for the time being, and what they can hurt? Thank you

if it's efi if the header hasket leaks are large enough it'll skew the o2 reading and simulate a lean condition and fuel mpg may suffer a little....but more often than not you should be fine as long as you fix the prob as soon as possible
