It doesn't sound like a fuel line problem ( though there's a small small chance it's a fuel pump ), it sounds like your engine isn't getting enough air on one end or the other. It might be a dirty air filter, or it might be a clogged cat or bad O2 sensor. Sometimes it's easy to tell if the cat is clogged, it will get extra hot and turn red and that's your ...

Typically it's to catch the blow-by. While the PCV system is designed to vent just air/fumes as Nick C mentions, as an engine wears it'll start to blow some liquid oil past. That's normally redirected to the intake so it'll burn off (as oppposed to just dripping it on the ground like the old cars used to). Car enthusiasts like to install catch cans (that ...

Most, if not all, internal combustion engines have a breather on the crank case, to allow fumes to escape from the oil pan. In a lot of cars (presumably including the RX-8), this is vented into the inlet manifold to prevent the fumes being released into the atmosphere. Installing a catch can in this breather can prevent atomised oil evaporating up the ...

Is the car running when you try to "get it stuck again by hand"? If not, remember that when the car is running with the throttle closed, there is vacuum being pulled against the throttle butteryfly by the running engine. Perhaps there's some play in the pivot or the assembly that allows the intake vacuum to pull the butterfly into a position where it ...

Turns out it was the water pump. Jim at Watson Automotive in Thetford VT replaced it ($400) and it's not stalled or flooded since. In the question I left out one clue that Jim used — a belt was squeaking. He found that was from a leak of radiator fluid from the water pump. Jim theorizes that low coolant caused portions of the engine to get too ...
