Ok,

I got a question, we all have valve covers with a hose to the intake manifold. The driver side goes to the rear the passanger side goes the front.

Now add in a catch can, and i have a leak somewhere...I also cannot take off the oil fill cap. There is so much suction its stuck shut...I think its the seal for the valve covers...

But back on track, i want to remove all conections to the intake manifold, and re-route it to the intake tube just behind the MAF sensor...My thought is i still keep the engine earth friendly, and i also keep the engine clean as well...Is this possible, or does there have to be a vacuum under the valve cover?

I am just tryin to minimize the potential leaks for the last two cylinders are lean and its goofin up my tune...Plus i havent had a vibration free ride since i did this...
