Passat (B6) :: Exhaust Sounded Like It Has A Leak - Possible Blown Diverter Valve?
Was cruising on the freeway and all of a sudden my exhaust sounded like it has a leak!!! I gave it some gas and it got louder but the car didn't pull like normal??? No check engine light or anything crazy. I don't think the inter cooler pipes blew off because the engine didn't shut down and I was on cruise mode.
Its sounds like the turbo wants to spool but cant hold boost, can this be the diverter valve leaking or its blown?? I haven't had the chance to check which diverter PN# I have but Im pretty sure its the stock OLD version. I am the 3rd owner. 07 Passat FSi variant with 36K miles.
I hear the 07 FSi are know to have bad or weak Diverters.... I know I needed to go with a stonger TSi Diverter which I hope is the problem here....

View 10 RepliesGolf/GTI VI :: 2011 - Grinding Sound Around 2k RPM / Diverter Valve?
I currently have a 2011 DSG. I purchased it last year and when I test drove it I did not notice any unusual sounds coming from the motor/ drivetrain. However since then I have noticed that the car makes a grinding like sound when my car is around 2k-3k rpms, its especially loud under load. Its a very audible sound, like something is grinding in the transmission- Everyone that has been in my car can hear it, and it only happens at low rpms. Anyway, I took my car in once to service and I mentioned it, however the tech said he could not hear anything.
I honestly think that I got louder since then so I took it back and the shop foreman came out for a drive with me. So the guy hears the sound, but says that its the diverter valve and that its supposed to sound that way. He tells me its because the cars now have a metal valve and that its louder. I had a 2002 A4 1.8t and it never made a sound like that, even after chipped. So Im a little worried that its something else and I wont be able to get it fixed under warranty, or maybe im just paronoid and the DSG sounds like this.
Golf IV / Jetta IV :: Lost Power - New Forge Diverter Valve Installed
So the other day I replaced my N75 valve and upgraded my DV to the Forge 007. For some reason the turbo doesn't spool like it did before, it's lost it's pep.
I've tried the Yellow and Green springs, also I tried them with the shim too. No luck. The car got turbo back exhaust, intake, and stage one program.
Passat (B6) :: CEL On / Code P0299 - How To Replace The Diverter Valve
The CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:
000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached
The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.

GTI 337/20th Anniversary :: Lag In Boost - Diverter Valve Throws CEL?
If your diverter valve is bad, will it throw a CEL or not always? I don't have a CEL but sometimes I feel like there is a lag in the boost. Wondering if the diverter valve is bad or not.

I've got a coolant leak here (I wiped away some of it before taking the picture):
Close up
This is the only place I can find coolant leaking and it's running down all the way to the water pump:
When I wiped away from just below the valve cover gasket it flaked right off and it doesn't appear there is any oil mixed in. I changed the oil today and it didn't appear to have any coolant mixed in either.
The coolant doesn't appear to have any oil in it's nice and pink as it should be. I started the car from a cold start and sat and watched the area waiting for it to leak but nothing ever came out, of course.
I know there shouldn't be coolant leaking from this area anyways but I don't know how else to explain the trail pictured. I definitely have a small leak somewhere as I've found coolant on the floor of the garage before.
Do I just replace the valve cover gasket and move on or is there something else I should be concerned with here?
Golf IV / Jetta IV :: Oil From Valve Cover Leak In Pistons
I drive a 2003 24V VR6 GLI
I recently did a valve cover repair to stop the dreaded misfire problem. Well, I'm still waiting on a few things but during the spark plug change obviously some of the oil from where the valve cover leaked previously fell into the pistons because I couldn't really clean it all out efficiently. This seems like it would cause a lot of problems? Do you think I should throw old spark plugs in there and let all the oil burn up before finally replacing them? I really don't want to foul up my brand new NGK's.
Also, I pulled p0300, p0305, p0306, so I am guessing oil in the spark plug/coil pack connection may cause some of the misfires, but do you think two of my coil packs are bad still? My plan was to move them around to see what happens after I get the new parts and am actually running again.
Golf/GTI VI :: 2010 - Oil Leak Around The Valve Cover Gasket?
I just noticed what appeared to be an oil leak around the valve cover gasket, which the VW dealer has determined to be a defective cam sensor. Apparently the VW parts distribution center in Wisconsin has 530 of these in stock, so it may be a common failure. This is on a 2010 GTI with 28,xxx miles. Thought the community would like to know.
View 2 RepliesCamry :: Oil Leak Coming From Valve Cover Gasket
so I have a 2azfe engine
So there's an oil leak coming from the valve cover gasket (just purchased vehicle dirt cheap with 220k)
found this
Notice all the oil sitting on top of the exhaust mani gasket
In the left(lower) part of the picture it appears to be scraped.
the gasket appears to be newer, I did NOT use a screw driver to remove the valve cover, which is what this appears to have been done..
Can this be sanded down then filled with jb weld, and then regasketed?
Suzuki - Grandvitara :: No Sign Of A Leak And Yet No Engine Oil - Bad PVC Valve
I own a 2007 Suzuki Grand Vitara, V6, about 104,000 miles. My mechanic recommended the annual oil change in December 2015. My vehicle started making a loud tapping noise July 2016, so I took it to a mechanic. My mechanic discovered my car had no engine oil and there's no evidence of a leak. I have to replenish the engine oil every three weeks. My mechanic recommends I replace the PVC Valve; I'm unsure if the issue is the PVC Valve or oil compatibility issue. Oh I must also mention (not sure if it's related) when driving or parked and my a/c is running, the a/c intermittently blows out hot air....I can hear the transition like another vent suddenly opens up.

I had my a/c recharged in April and it was blowing hot again by July. I brought it back in today and they told me that it is leaking out of the Schrader valve on the low pressure side. They told me that they would have to replace the entire line which would cost a few hundred just in parts. Why can't they just replace the valve. The tried calling auto stores for a special part, but could not find one. How to seal or repair just the leaking Schrader valve and not the entire line?

I have a 07 Sonata and having recurring valve cover leak. First time it happened it leaked onto my alternator and had to get car towed and whole bit.

I know this is an established problem but how many times can the same problem occur?? I'm passed the warranty (103K).

I have a 2009 Santa Fe Limited with 82000 miles. I have replaced four (4) batteries since it was purchased, new, in March, 2010. I have repeatedly taken it to the Hyundai dealerships in Las Vegas, Nevada and Centennial, Colorado, for an oil leak on the valve cover over the alternator. At no time has the service technicians at the dealerships ever told me there was problem. Last Thursday, the latest new battery, installed that same day, failed. I had my independent garage technician assess the multiple battery failures, with the associated battery display light illumination, related to the location of the continual oil leak. He stated that the cause of the battery failures was from the oil damaging the alternator. I contacted Hyundai Customer Service, today, and was told that there have no reported problems from oil leakage onto the alternator, with subsequent damage to it, and/or the battery.

Also replaced the evaporator . They charged it the last time, it was parked for a week and I started it up and no ac. Took it back to ford and they said there was no freon. They removed the dash again, put dye in and can't find a leak. They claimed they used a black light and Cannot find leaking dye anywhere. I picked it up today and the ac works but prob not for long. Any clues?
