Passat :: 1997 Volkswagen - Engine Compartment Sounds Like Vacuum Cleaner
Recently my car has been doing some weird things. After driving it for about an hour, I get a sound from the engine compartment that sounds like a vacuum cleaner. It's fairly loud, but it's mostly just noticeable from the outside. The car continues to run, but if I turn it off, it doesn't restart (does not even crank). Last night I was driving at about 55 MPH and all the electronics went off and then came back on. In other words, the radio restarted and all the lights turned off and back on. The headlights turned off, but they did not come back on no matter what.

So.... here's my issue. I have a 2001 supercrew 5.4 and runs great all day long, no problem starting or anything. After I have driven it for a while and turn the AC on it cools off very good then after about a 1/2hr. the truck tries to stall. It almost sounds like a vacuum leak and really bogs down. I can wait about 2hrs and then with the AC off the truck starts and drives like it should. I am steering to the IAC valve but would like to know if this is it.
View 9 RepliesGolf V R32 :: Exhaust Or Vacuum Leak At Higher RPMs
Recently bought a MKV R32. Already had a magnaflow cbe, k&n panel filter, and some emissions stuff taken out from under the hood. not sure if it has been flashed, waiting to get a vagcom. think it is pretty stock other than that. My problem is about 2 weeks after I got it, I started to notice an exhaust leak or vacuum leak or both at higher RPMs, like above 3 or 4k it starts. The exhaust has a nice deep rumble in normal driving but when the leak noises start that is all you hear, the exhaust note disappears completely. I have tightened the clamps on the cbe and still does it. Not sure what to look for.

I recently started to notice what sounds like a vacuum cleaner coming from the engine at start up, usually in the morning. The sound continues for about a minute or less then goes away. Haven't noticed it after repeated starts during the course of the day. Car runs fine, no CEL's.

So I started my truck this morning and it sounds like air rushing out from the driver side of the engine. I currently have my ICP unplugged due to a bad sensor, will be replacing it on Sat. Also I have been having an issue with my turbo but I don't think that it's related as I here the air rushing sound when at idle as well at when driving. It seems to be a bit louder when the engine is cold but I could also be crazy about that.

I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!
Prius (2004-09) :: 2006 - Check Engine Light - P0420 Code / Air Leak In Exhaust
So today my CEL came on. I immediately looked at my mileage and I was EXACTLY at 500m past my oil change the other day. I checked the dip stick and lo and behold, it was about 3/4" past the full marker. I took it back to the oil change place and had them drain it down to a good level.
I had driven from NH to NY this week. I filled up my gas tank on my way home from NY. Gas cap was on nice and tight for sure.
The code is still on (not sure how many miles or drive cycles is required) for something to clear. I figured it was perhaps due to too much oil added. I decided a few hours later to take it to AutoZone and grab the diagnostic code. It's a P0420 code (Cat System efficiency below threshold: Air leak in exhaust before rear HO2S, AF Sensor Error, Fuel System Fault, Faulty Catalytic Converter).
Ford A/C :: 2004 - Vacuum Leak Under Dash When Control Set To Off Or Maximum?
I have a 2004 F250 CCSB 6.0 diesel. The problem I'm having is that vacuum is bleeding off when the control is set to OFF or MAX A/C. I also have no vacuum at the MAX A/C level to close the heater valve. Looking for a vacuum schematic for an 03 or 04 truck with manual controls or how to know what the malfunction is?
View 2 RepliesFord F-150 (2004-2008) :: Small Vacuum Leak In 4WD System
Long story short, I have a small vacuum leak in the 4wd system. I disconnected the lines going to the hubs to prevent grinding them to pieces as they are brand new. This, of course lock the front hubs in and disengages the X-fer case in 2wd.
It is not engaging in 4wd unless I select it, so I don't imagine it hurting anything in the X-fer case or anything. Other than the extra rolling mass, is this okay to operate at until I resolve my vacuum issue, provided I close all openings and places for trash to get in?
Ford Escape / Hybrid :: 2004 V6 - AC Defrost Only - Vacuum Leak
I have a 2004 Ford Escape 3.0 V6 FWD, and the air conditioning has been blowing only to defrost for a few weeks now. After many searches online, most sources seem to agree it is a vacuum leak, as the selector switch is vacuum driven if you want anything except defrost. I popped the hood and within one minute I found one open vacuum line that looks like it has been worn in two.
The line in question goes from the vacuum canister towards the passenger side of the firewall, then goes to a T connector, then a line (the one that is broken) continues towards the heater core lines to where the break in the line is. I found a picture online of what it should look like, but I am having trouble accessing the line that goes through the firewall and behind the glove compartment. I am pretty sure this vacuum line continues through the firewall between the two heater lines, but after that I am stumped.
I popped the glove box down out of the way and I see two thin vacuum lines and a small metal "can" nearby. The black line goes from a fitting and into the A/C bundle, and the white line goes from the top of the metal canister and down into the same bundle. My main question is which line controls the AC selector, and how do I pass a replacement line through that part of the firewall to make a good connection, as it seems the break is at the firewall itself with no extra sticking out for me to connect to.
Ford F-150 (2004-2008) :: Vacuum Leak Causing Erratic Idle - Codes PO171 / 174?
I tugged on the little hose on the back pass. side of the engine,(5.4),...
and I could hear the vacuum leak that is apparently causing the erratic idle, and PO171 & PO174 to come up.
I know this hose is hooked to the Charge motion Control Valve on the back of the manifold,..I can't imagine what it does, as it terminates with some kind of plug or check valve??? Haynes say's to remove the entire manifold to get to the CMCV.
I can see it with a mirror,. I am thinking maybe long needle nose from Harbor freight,...bend the tip short,..maybe be able to change it out?????
Ford F-150 (2004-2008) :: Exhaust Leak On Passenger Side
I have an exhaust leak on the passengers side of my 2006 F-150 5.4 triton. If I do the repair which is the correct way to do it? Do I replace just the blown out gasket?
Do I need to buy a new exhaust manifold and gasket kit, with exactly what parts should I buy in the kit? Or do i need to replace both sides?

Ford F-150 (2004-2008) :: Exhaust Manifold Leak On Passenger Side
2004 SCrew, FX4, 5.4 ... I had the dreaded exhaust manifold leak on the passenger side. After reading the horror stories of this repair and living in the rust belt I decided against fixing it myself. I took it to a local repair shop to have done. Initially the mechanic could see that the front 2 studs were snapped off (before even trying to remove them).
After a full day of fighting the studs (engine loose & lifted up) everything is out but the front 2 studs. the top one has about 1/2" exposed, but it is frozen in place (penetrate on it overnight). The biggest problem is the bottom stud. it is broken off about 1/8" below the surface of the head. The guy doesnt have a small enough right angle drill to get between the frame & head to attempt to drill it out. I will gladly go buy a drill for him to do this, as it will likely save me money if it will work to drill out the stud.
Need to get the 2 studs out, particularly the bottom one, or what right angle drill may fit in there?

View 3 RepliesFord Exhaust System :: Exhaust Leak At Manifold Where Donut Gasket Meets The Catalytic Converters
My truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....
