Chevrolet S-10 :: Rats Ate Vacuum Line


Apr 15, 2013

6 cyl. vortac engine, air, 4WD utility model. The HVAC controls quit working and I just drove it - then after a few months the heater core started leaking. I had to fix that. While I was under the dash getting ready to put the new core in, I spotted a T in a vacuum line that went to an actuator on the passenger kick panel, the line to the actuator was intact. But the T went about 6 inches then thru a rubber plug (round with a cone shape on one side) hanging in space and about an inch on the side that was cone shaped the end had been chewed off.

Perhaps that is why the HVAC control quit? No other line can I find that it connected to. I have not been able to locate a vacuum diagram on the 'net. Or even find a hole somewhere within range that it might have passed thru originally. Much less the other end of the line, I guess the rats took it with 'em? where this line connects? or have a diagram??

Phaeton :: Burning Oil Smell - EGR Vacuum Line Disconnected?

My Phaeton had the typical burning oil smell so I suspected the Camshaft cover gasket. However when I looked at the service history the gaskets were only just changed in 2012.

When I inspected the car closely I found the RH EGR vacuum line was disconnected (pipe cracked through).

Unlike the Audi A8, the VW 4.2 looks like it has 2 EGR valves, and not one. So I reconnected it, and so far, the burning smell is now gone!!

I am a newbie on the VW 4.2 but is a disconnected EGR a likely cause of oil leaks? (ie positive crankcase pressure). It makes me wonder if all the people whom are changing their cam cover gaskets, should be checking their PCV/EGR's instead??

Lexus SC430 :: Code P0308 Because Vacuum Line Disconnected?

Lately I have been working a lot with my cold air intake. One of the vacuum lines keeps popping off. Today I got a check engine light and VSC and VSC off light. Is that due to the tough idle caused by the disconnected vacuum line. I erased the code and so far it has not returned.

Volvo :: Engine Computer Test - Sputters Unless Disconnect Vacuum Line

I replaced the engine computer (1346107) with one from ebay. Now it runs but sputters unless I disconnect the vacuum line (still sputters but a lot less). with it connected, the timing is off (to about 15-18 instead of 12). the distributor is rotated as far as it will go. Need to recognize these symptoms? Is there a procedure to test the ICU?

Golf IV / Jetta IV :: Brake Vacuum Line Is Cracked After Check Valve On Intake Side

Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.

I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?

Ford Super Duty (1999-2016) :: 2001 - Stalls While Slowing Down / At 15 Mph - Vacuum Line Burnt?

I have a 2001 F-250 7.3 diesel with an automatic trans. Over the last couple of months it has stalled 3-4 times while driving, always when slowing down but even at speeds of 15 mph or so. I did find a burnt vacuum line the other day. It comes out of some type of relay box located behind the battery and in front of the starter solenoid relay and is mounted on the fender. It has an electrical plug in the top and two vacuum lines at the bottom. I am hoping this is the cause of the truck dropping off of the idle circuit? But I don't know what the unit is so I cannot order the correct replacement lines.

Chevrolet - Lumina :: 1997 - Vacuum In Gas Tank

I have 30k on my 97 Chevy Lumina. there is so much vacuum in the gas tank that it crushed the tank. I have replaced the tank but don't know what the problem is. Have taken it to three different shops and got three different opinions. One shop replaced the purge solenoid, no luck. Another said there is no fuel tank pressure data and want to drop the tank and check the sensor. the error code they read is p0440. The other replaced the evap canister. Am driving without the gas cap to protect new tank.I don't want to pay for another unnecessary repair and am sure I can repair it myself but want to be cartain I have it right. Also I didn't realize there was a pressure sensor in the tank. They also said I could have a restricted vent valve or canister.

Chevrolet - S-10 :: 1996 - Brake Booster Vacuum Leak

Brake pedal whistles and is hard to push. Only happens intermittently. Mechanic wants to put new brake booster on. This would be 3rd brake booster in 9mos. It's gotta be something else. What does the vacuum hose connect to from the check valve; where on the intake manifold? If no PVC valve...then what else? Truck runs fine...no fast idle or rough idle and no hesitation.
