I just replaced the (cracked) intake on my 2000 GT with an aftermarket one of the newer aluminum coolant crossover design, and I saw lots of baked on oil sludge in my throttle body, the factory intake manifold, and in the runners into the heads. The runners were clean below the injector's spray pattern.
I've also noted that my throttle is sticking when I first press the accelerator pedal, for the past couple of months, and I can hear the valves rattling as if the octane is too low in the gas. I had to replace the IAC valve a while back and even earlier had to clean a lot of sludge out of the factory original, as it wouldn’t hold idle.
Finally, I don't have any leaks on the garage floor, and I don't see any smoke from the exhaust, but I am using about 1.5 quarts of 5w-30 consistently between oil changes.
I've got about 137,000 miles on the 'stang, and I am the original owner.
Is this possibly an issue with a faulty PCV valve, or are these symptoms of something else on the intake side?
Thanks in advance.
