intake tube be for what?
This is my question and I figured it out. You remove a spring clip located in the end of the intake tube where the hose goes in. Then you are supposed to be able to pull it. Mine had been in so long it was stuck. I had to take the turbo intake tube off (no small feat) and get it on the work bench. Then I bumped the hose loose from the tube with a punch. Every thing went together better than it came apart. I suggest most people leave this job to a Volkswagen mechanic.
There is a metal tube that runs under the intake manifold. It goes from the back of the water pump to the rear of the engine where it changes to a rubber heater hose. That metal tube is known to rust out and leak coolant. The intake manifold must be removed to gain access to the tube for replacement.
The BOV for a 1987 Mazda RX 7 Turbo II is located on the top mount inter cooler pipe from the turbo to the air intake pipe right after the air box, just above a vacuum source. By simply disconnecting the BOV from the intake tube befor the turbo but after the intake box, you get the air pressure release sound commonly heard on many "tuner" cars.
No, not for the hose but, I have seen the metal bypass tube that the hose connects to, rust out and cause a coolant leak out the back of the engine. The intake manifold would have to be removed to replace that metal tube.
Replace the drink tube assembly
The intake is the tube that attaches to the engine - usually the carburetor is attached at the opposite end of the tube (intake).
Well, no. But its normal for the float in the carb to get get stuck and cause the gas to overflow through the overflow tube.
The leak is your water inlet tube behind the thermostat housing. It's a dealer item only, about $90, and it's very difficult to install.
replace the drink tube assembly
an iat sensor is almost always located inline with the intake tube. i work on so many vw's at heart volkwagen i cant remember exactly where it is. if it is a turbo it will be most likely mounted on the inercooler. just check for a 2 wire sensor online with the intake tube.
