1999 Volkswagen Jetta 6 cyl Front Wheel Drive Manual

Hello,

I have a 1999 vw Jetta vr6 5 speed manual.
The breather hose for my pcv valve was removed by a mechanic because it was cracked. He couldn't fix it, and left the hose off saying only my gas mileage would be affected until I get the vw part and put it on myself.
When the engine is off I can shift through all gears smoothly. But when the engine is on the clutch pedal doesn't seem to have the proper resistance and it is hard to even get the car to shift into first and then sometimes you can get into the other gears if you are lucky. But once you drive for a few miles the shifting gets easier and easier until it shifts normally. Ever since. Is this because of the missing breather hose or could someone who doesn't drive stick have messed up the cable linkage alignment for the stick shift.


Thanks

Matt

The PCV valve has nothing to do with it. Ifit is a hydraulic clutch it may be having an issue with a little air getting into it, then when used a little it is forced out giving proper pedal pressure again.

Jack,

It is a hydraulic clutch. I can understand that.

But why would I have alot of trouble to get the shift lever to get into first or any of the other gears?

The clutch pedal resistance is not the main problem to me. Being able to or not being able to select gears is the main problem. Sometimes if I can get it into first or reverse I can not get it out it is stuck there. Would the hydraulic clutch affect that or would that imply a problem with the cable/shift linkage?

I never had this problem until I took it to the mechanic for diagnostic testing. Is this just coincidence?

Thanks

Matt

If the hydraulic system is sucking air, it wont work the clutch properly and you wont be able to get it in and out of gear. Sounds like it is coincidence.

Jack,

Brought the car to a VW dealer. FYI, it turns out that the brake fluid while full was dirty. After the brake fluid was flushed and new fluid put in everything works fine. No hydraulic leak. But thanks for your info. It was helpful and I enjoyed using your website.
