It is a hose that connects from the air filter to valve cover that stops contamenents from staying in the engine.
Blow-by Engine is getting tired Excessive engine wear bad rings
In/out hose located on valve cover (fresh air) Dirty air sucked in through breather hole on manifold
My 2000 Jaguar S-Type did that. As soon as I fixed the lower breather hose on the engine, it stopped doing it. i am assuming that the lack of air is making the engine suck harder. A way to find out, and I heard mine clearly, is to pop the hood and listen for a hissing. I said my lower breather hose but mine was actually my upper breather hose. It's just the lower breather hose is the most common problem in vacuum leaks in the 2000-2003 Jaguar S-Types
in engine cover.it connects to the breather hose on the RHS of the engine cover.
The 4.0 engine was designed with a Controlled Crankcase Ventilation hose - the smaller at the rear of the valve cover, and a front air inlet hose from the breather. It moves crankcase gas into the intake manifold through the small hose, and has no PCV.
On the top side of engine, underneath breather element tube, under top radiator hose
I believe it's the hose that attaches from the air filter into the engine. It may look like an accordion or a bendy straw. I'm looking for one too
yes, but it will make th engine stall and knock like craise
It depends on the year, for Cougars made from '99 till '02, the Automatic Transmission Breather hose is located on the drivers side of the engine, underneath the battery tray.
The vent hose is for either the transfer case breather or the transmission breather. A light amount of oil residue is normal. If there is a lot of fluid coming out of the hose then it is most likely caused from the transmission getting too hot.
A breather is something you put on your gas tank to let the fumes out. It is the hose coming out of your tank.
