What did I do??

[Shantae516]

Ok, so hubby pulled off the timing cover yesterday to check everything out, and it looks good we started the car a couple times to check tension on the belt and everything was fine, so he put her back together. He checked my oil and noticed I was a little low so he added a quart. Now, she idles a little rough, like she wants to die out and sounds different than she did before when driving. Like, idk a little whiny. I'm so sad I don't know what oil she had in her but I just wasn't thinking when he put the new stuff in. Could that be the prob? Doing a full synthetic oil change today, hoping this cures the prob. I'll let you guys know.

Off the top of my head, the connector for the cam sensor is there, perhaps there is a loose connection now.

When is the last time the plugs and wires were changed? FYI, never pull on an NB spark plug wire to check it for connection, unless you want to buy new ones.

On the 2.0 engine, you have to remove a vaccuum line from the intake to be able to remove the top cover of the timing belt.

If that line is not connected tightly, or it has a leak the bug will do exactly what you described.

The exact thing happened to me and once I fixed the leak/hose the car ran perfectly again.

Ok so we checked the hose hubby says he put it on tight. But the little black box the other end of the hose goes in has play. Is it supposed to, or is it supposed to be tight. Not where the hose goes onto the plastic elbow, but where the plastic elbow goes into the black box. Sry just a little frustrated here. It was fine and now its not and we didn't even do much of anything lol

[D2Beetle]

Some of those vacuum hoses are cloth braided and prone to dry rot; you may want to consider replacing it/them. Regarding the "little black box", that is a somewhat ambiguous description, if you could take a picture and post it, that would be helpful.

[Shantae516]

alg referred to the vacuum line from the intake in a reply...I was talking about the other end of that hose where it plugs into a black box with 4 other hoses right behind the coolant res. I can take a pic tomorrow, tonight I am very frustrated I just really have no ideas on what this could be...seems like maybe a vacuum leak but we checked and double checked. I can't at all believe it is not related to the fact that we had some things off the car when we were looking at the TB.

[Shantae516]

Ok, so there is this metallic sound when I give it fuel....hubby pulled off the hose that is connected to my oil fill. WTH is this gunk??? plz guys any help would be appreciated.

AEG dont technically have a PCV system. However, what you are looking at is the equivalent to the AEG PCV system.

Firstly, that black round cylinder. Unscrew it from the top of the valve cover, and clean it out. The hose that all the gunk is in, replace it! Oil eats rubber, any petroleum based product will eat rubber. That tiny hose with the lil' bend in it ranges from 15-30 bux.

Surprisingly, that "yellow" sludgy stuff your seeing, is completely normal on the Beetle, you are the 10 millionth person to find that nasty stuff. That is caused by condensation mixed with the oil residue. For the most part, its normal. However, if the hose gets clogged, it wont breathe properly. Need to replace ASAP. it is normal for a little bit of oil to go through that hose.

Next, take off your intake piping. You need to look in there, and see if there is this same sludgy build up inside the air intake piping. If that is clean, everything should be ok. if it is not, you have a problem.

Also, when you change the oil, if you see this stuff, any amount flowing out of the drain plug, this means you have a "major" sludge issue.

Here's the thing, I assume you havent been using synthetic. Synthetic will eat away sludge over a period of time of use. However, if you have used conventional the sludge has built up around your seals and may have eaten them away, and now the sludge is acting like a seal. If you take away the seal, you get massive oil leak. Be careful since you havent run it on 100% synthetic. It wont happen with one use, but constant use for a period of time could result in what I said above.

if you dont want to use and spend the money on synthetic.
Get the synthetic blends, the molecules are more refined they are smaller, and will last longer, and still eat at the sludge little bit by little bit. Synthetic blends are actually really good oils, not as good as synthetic but "way" better then conventional.

I just replaced mine a few weeks ago, hose was squishy and eating away from the inside out. Judging by the pics, your is much worse then mine. This may not fix your problem, there maybe another cause however, clean it out and get a new hose!

I need more details, pics, counds etc... to try and diagnose over the net. I know its hard to believe that the "yellow" stuff is normal, for a few weeks I denied its existence as normal. So I went to 2 VW customization shops been in business for a combined 70 years, and went to a dealer.

BTW the hose at the dealer is 30 bux. Anywhere else its 15...

[Shantae516]

Hubby is gonna pull that apart and check it. The thing I don't get is it was totally fine until i put one qt of reg oil in by accident and now its all screwed up. It has a very slight hesitation when i start it. if i give it the slightest amount of fuel it smooths out but if i give it a lot of fuel it makes this tapping or metallic kind of noise. we did do a full synthetic oil change, so now I will watch out for leaks but it looks like i wont be driving it much anytime soon. Though it is drivable like this, I dont want to make it worse sad panda

[Pseudotropheus]

What kind of ticking or clanking noise is it? Is it coming from the motor, or elsewhere. Need more info to try and help out a little more.

I cant here the sound so I cant tell you what it is. Try this I want to inspect your vaccum lines, and I assume you have no vaccum pressure tester.

Start the car, after warmig up I want you to hit the gas pedal really fast, tap it really quick and let out. Dont hold it down, just tap it really quickly. Does the car cutout?

[Shantae516]

LOL I'll pm you my # and let you listen to it

[Pseudotropheus]

That might work.

[cep]

You may have overfilled it with oil, too. Did you check it after you put in that quart?

[Shantae516]

yeah, oil lvl is perfect. PM sent

[Pseudotropheus]

Hopefuly we solved the issue. At least some of it.

[simonsi]

C´mon, what was the noise? We are all interested and waiting

[Pseudotropheus]

I will let her tell you what the noise was from.

I don't want to say anything in case it didnt fix the noise. From all diagnostic standpoints, it should. However, cars are like a box a chocolates, you never you know what your gonna get.

What are you talking about...??? The AEG DOES HAVE A PCV...??? Where you put the oil in the engine is the PCV !!?? Take the PCV valve out of the valve cover and de-grease it as well as the hoses... If you find that the hoses are detererated replace them ,same with the PCV. Also if you look at the picture you can see that the gasket for the oil fill cap needs to be replaced as it is obivously letting in condendsation.Same with the gasket under the PCV. Both of the gasket's are cheap to replace. If i we're you (OP) I would remove all the intake hoses and make sure it's all cleaned of oil and condendsation including the airbox. If this was my car i would go over all the hoses and belts as this car has not had a good maitenace record and has probably sat and not run for a long period of time before you bought it...GL....KP...

DITTO...What's the poop...???

[Pseudotropheus]

I was told that on the AEG, it is a PCV system, but the technical name for it is different.

They call it something different. I cannot remember the name for it, I can get it for you this week.

2 VW customization shops and 1 dealer, Larsonvw.com service also said the same thing. They dont call it a PCV system.

I specifically called all 3 places looking for the "breather hose" in the "PCV" system. They corrected me everytime I said PCV system' wish I could tell you what the hell the name was...
