Thanks. I wanted you to answer those questions, but didn't think you could get any more credit on the same thread...so I posted fresh. Since that post, the shop advised that on initial inspection, all cylinders were affected, so a top down oil source was suspected (vs rings/valves in one cylinder). He claimed to experience excess vacuum, so he went ahead with the PCV replacement and replaced the breather diaphragm in the valve cover (still not sure if this is a good fix, nor where they got this part...I've only heard of replacing the whole valve cover). Anyway, it was still smoking upon start up...so they thought it might take a while to clear out. I think they went ahead and cleaned up the oil in the intake/throttle in some way...and...
...got it to STOP smoking. But when they ran it (or drove it?), the smoking eventually returned.
At this point, I think they started to give up, wanting to claim internal problems...blow by...wash hands...take to dealer...which did not sit great with me. I mentioned the secondary PCV-like system in the oil filter housing, which I've read can cause the same problem as the PCV/breather in the valve cover.
They were not aware of this second system, and went back to look after it. That was 1.5 hours ago, so perhaps they are on to something.
I'm thinking it shouldn't be too hard for them to isolate these two PCV vacuum situations, and figure out which is causing the problem.
Have you seen the same problems with that second PCV system, in the oil filter housing? Just much less often than the valve cover? It seems lots of codes and problems are related to the darn valve cover, no?
Hi Chris. I tried to direct a new question to you...twice. But they keep posting as all experts. Anyway, there are two identical...new...questions hanging out there. If you can grab both for credit, great. Thanks.
Hi Chris. I have a new question for you specifically, but the system won't allow it to be directed to a particular expert...IF...it has already been asked to the whole group. So, I will put it here, and add new credit when you reply. Hope all is well.
Most of our mechanical repairs, problems, and maintenance have been resolved. Here is the latest:
2006 Jetta 2.5 with 6spd Automatic (non-DSG) transmission. 77k miles:
The trans used to have about a 3 second delay when shifting from park to drive...in the morning when cold. In the past 3 weeks, this delay has increased a lot. Tested this morning: 50-55F degrees. First start of the morning. Shifted immediately to D (not Sport or +/- manual), the started a stopwatch. 9-10 seconds before drive started to engage.
The VW dealer says this is not abnormal, and that many customers report the same experience. The dealer says it is a truly sealed unit (sealed for life), and you do NOT service this transmission at all (no fluid changes, etc.). There is no dipstick.
Other say 3 seconds is fine, but not 9-10 seconds...no way.
The transmission seems to operate perfectly once warmed up, and shifts smoothly and reasonably quickly up and down whether automatically or manually.
I did note an odd nuance that, even when dead cold, if I pull the shifter over into the manual shift mode (+ and -), it will engage immediately into forward, without the 9+ second delay experienced when shifting from park to drive.
Either the colder morning temps are affecting this trans, but to a higher than acceptable level. Or perhaps there was some collateral damage during one of the many other repairs. Maybe someone knocked a trans hose loose, and then replaced it, spilling some fluid. Who knows?
Any explanation? What should we do? Thanks
I went to the VW dealer where I know the manager, and the tech. There were no trans leaks/seeps, and no trans codes in the module. He said the trans fluid needs to get down to a certain temperature (cool off) before he can accurately check the level...so we couldn't do that today, since I had been driving it...and it was way too hot. I'm guessing the fluid is probably a little low, and the increase in cold shift time over the past three weeks is probably due to the colder morning weather. I'm not sure if we will pursue this further. My friend is selling this car, and I'm not sure about opening up the sealed system at the point. The tech said that as this NON-DSG sealed trans approaches 100k, they recommend NOT opening it up or changing fluid at all. The fresh fluid seems to cause more problems than it solves. I'm just passing on what he said.
As always, thanks Chris. I will rate excellent.
