Phaeton :: Burning Oil Smell - EGR Vacuum Line Disconnected?
Jan 29, 2016
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??

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.

Recently I have been having a strong gas smell coming from my 1997 F150 Supercab 4.6L 2wd. It is not happening all of the time. I have also been hearing what sounds like a vacuum line leak. A loud shrill which varies with the engine rpm. This also does not happen all of the time.

I have always had a occasionally burning smell in the cabin when I am using the heating system. Has never happened in summer. Only happens randomly in winter when I am using the heat. I don't think I have seen steam and stuff and definitely no water puddle in footwell area. This strongly makes me think that I have a leak in the heater core area, maybe not the core itself, just o-rings and things like that. Vw has checked many times and replaced the valve gaskets. But the smell is still there. This morning when the smell came, I opened up the hood immediately and I think the smell was around the passenger side plenum chamber area.

Just got a weird chemical smell on my way back from lunch and the a/c stopped working. Pulled up to the garage and there was a smell of burning under the hood, plus a fairly loud hum, and also these weird noises that sounded like electrical discharges from underneath.

Put down the passenger window today, heard a clunk, and now it is loose, as in disconnected from mechanism. Won't close all the way by itself. I have to manually pull it up.

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??

My car has been missing after a recent spark plug change, so i did a smoke test and i see smoke coming from under the air cleaner and i see that the accessory vacuum line goes under there, could this be the cause of the misfire? i already checked all the sparkplug work and wires. and if this could be the problem how would i get to it 1998 Buick century 3.1.

Was wondering if it is safe to use seafoam through my brake booster vacumm line? If I drip it in SLOW can I still hydrolock my engine?

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?

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?

02 F150, 5.4 gas motor, about 338k miles. Bought this truck well used so I would have a truck when I needed one. Someone has removed the heater control valve. I've got a new one, but there is a port on the top for a vacuum line, but where this line plugs into.

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.

On the way into work today, I smelled a burning smell in my cabin. Got to work and opened the hood and it's very clearly something burning in the engine bay.
Coolant levels are good (even opened the coolant reservoir and it filled back up a bit, so it doesn't seem there's a coolant leak there), checked the dipstick and oil level seems good. MK6 GTI, just hit 21.5k miles. The only things I can think of are:
-Haven't replaced the cabin filter
-Intake may need to be cleaned? It's been on for about 10-12k and hasn't been cleaned yet.
Might also be just because my senses are heightened because of this, but the engine sounds louder than normal, specifically the lifters sound louder, but might just me being paranoid now. Been hearing about the headgasket possible 2.0 recall that's been bouncing around, so could it be that?
I want to take this to my car guy, but he's about 1.5-2 hours away, so I'm iffy on driving it that far.

Three times in the past few months I have smelled something burning in my car. It only lasts for about 10-30 seconds. I've taken it into the shop to have checked with no results. One dealer told me I was smelling burning leaves caught in the manifold. It sure didn't smell like burning leaves to me though.

So i had a burning oil smell for 2 years. I finally brought it to the shop and had the valve cover gasket changed as well as the chain tensioner gasket. I now have a constant burn smell. It cannot be burn off because when i open the hood i see it dripping on the cat. converter i just cannot see from where. I seems to be right behind the heat shield that covers the edge of the valvle cover. What else could be wrong here?

I have a 96 camry that has a minor oil leak. I have taken it in to get checked, and the mechanic told us that as long as I'm willing to keep putting oil in it every month, I don't have to fix anything. However, lately the car has been making a burning smell, especially when I turn on the heater, and when the car is low on oil. Also, my oil cap has some yellow gunk on it. I'm concerned that this means water is mixing with my oil.
