sucking noise
sucking noise I have this noise that is sort of a sucking noise along with my lifter noise. It sounds like it's louder on the passenger side of the car. You can hear it in the fender well on the passenger side. I have done many things to fix this problem
but I am totally stumped.
I checked the PCB hose and those air valves off the exhaust manifolds egr lines and am completely stumped.I also checked the lines on the back of the intake manifolds. I need some help please.

Take a spray bottle full of water, and while the engine is running, start spraying it all over your intake gasket surfaces, and the hose connections. When you hear your idle change, you've found your leak.
You can do this with flammable gases as well, but that can get dangerous if you're not careful. I have always found my leaks with just a spray bottle of water.

I also like to use water. If you don't find it, it could be one of the vacuum hoses, so inspect each of them. Just don't start replacing things, as you will end up wasting your time and $

There is a vacuum line that's wrapped in foam that runs along the passenger valve cover. Around the #4 cylinder it slips into another line and can pull out but when spraying for vacuum leaks the motor won't surge because it's wrapped in foam. Had this happen to me but I also had my intake off 3 times in 2 days so I was pulling on **** a bit. Just something to check quick
I took a bottle of water and sprayed everywhere.I have sprayed many times and have come up with nothing.I thought it might be the passenger side exhaust gasket. I plugged the air hose to exhaust manifold and nothing.
I am still stumped as to what it is.I was thinking that there may be a leak in the rear of the intake manifold.I put a rag in back of the intake manifold and the noise did not change. The sucking noise seems to be on the passenger side.Do you guys have any suggestions?

I am still chasing this thing. I disconnected the wire harness on the air pump.I thought it might be an exhaust leak, but now I don't think so.I have sprayed and sprayed and I can't seem to get anywhere.
Now I think that it is in the intake manifold. I would like some ideas as to where to go to fix this problem.Can't anybody point me in a direction that will help me fix this thing?

Try this. Get a cigar and a nice bottle of liquor like Templeton or something.
Remove your air lid, MAF, etc to get to the throttle body.
Light the cigar and with the throttle blade open, blow the smoke into the intake and quickly close the throttle. If you have any sort of vacuum leak, you'll see smoke coming out.
Now, go get a shot glass, a really nice robe, and smoke the rest of the cigar while sipping the Templeton and pretend you're the most interesting man the world for 20 minutes or so
You can use a hookah also but your car will smell fruity for a while. Cigar smoke smells more manly.
