Scrivyscriv's 1967 java green sunroof sedan (stock)

Risky surgery tonight.
I managed to snap the needle off, but the superglue repair seems to be working!

I had the worst speedometer squeal that was getting louder every time I hit 45MPH. I used Molykote paste to fix it, and thankfully I didn’t find any other broken gears or parts. The needle reassembly was a little tricky but I found there’s a sweet spot where the needle shaft seats down into its tiny little bearing.

Overall I think the speedometer squeak is fixable without disassembly. If I were doing it over again I would dribble some 3-in-1 down the input shaft. It’s not as much of a long term fix but much less risky than tear down for cleanup and regrease

Good work. You’re not afraid to tackle anything!

My 67 speedometer bounces. I’m not sure if it’s fixable, or what would cause it, but eventually I will probably dig into it like you did here.

Yeah, there’s not too much on here I’m scared of tackling, except getting into the gear set in the transaxle! That’s why I like these cars so much. They are so user-friendly and designed for an average mechanic to fix!

I don’t know why a speedometer would bounce - from looking at the mechanism, I’d hazard a guess that there’s dried grease on the spinning cup causing it. It only takes two twist tabs to separate the drive mechanism to clean and grease the gears!

You mentioned that you broke the needle. Is that pretty easy to do? Knowing what you know now, is there a way to remove it that would reduce the risk of breaking it?

I’m not sure when I’ll tackle mine, but I will file this away for future reference!

The needle was just collateral damage and a total accident that it even happened! It doesn't need to come off just to clean and grease the gears and input shaft.
Look at the second picture in my post above, where I'm holding the drive mechanism: In the very center of the mechanism there's a tiny brass bushing, with an even tinier hole in the center. The back of the speedometer needle shaft rides in that bushing. When I was reassembling the body back into the chrome and glass, I did it with the glass flat on the table, and the body of the speedometer facing down. The needle shaft got dislodged from its tiny bushing and caused the needle to stick in place. I opened it back up to fix the needle and get its shaft lined back up; I accidentally put pressure on the needle with it resting against the little "zero" peg, and the tip just snapped off and went across the kitchen like a rocket!

It only takes two twist tabs to separate the input mechanism from the odo and speedo mechanism, after the chrome ring and glass come off of course.

In the bus world a bouncing needle has to do with the cable. A new lubed cable usually fixes it. I’m currently using a cable from Autozone in my car.

Thanks for the needle link!

Pretty good frost last night. Man it was chilly at work!

Guys I've run out of motivation again. I had a great momentum going, then the fuel delivery problem just sapped it all

This old green tart has lived under my roof for five years without paying rent! I backed her out to a parking spot on the concrete driveway parking area right after Thanksgiving, partly to get some space back for a bit, and partly to see if she's water tight

Turns out she isn't


I had over an inch of standing water in the back seat footwell area of the pan after a series of storms moved in. Pop outs? Roll down windows? Sunroof? Who knows. I mopped up the bulk water, drove her back into the garage (much to my girls' disappointment - it had turned into a super fun playroom ) and rolled the windows down.

The next thing on my list is to check the fuel pump for output volume and pressure. I rebuilt all the major parts: the stock square-top Pierburg pump has a new WW diaphragm (the good one) and I'm almost positive I correctly preloaded it all; the Solex 30 pict is rebuilt, with only the accel pump checkball left untouched; and the distributor is a stock Bosch 113/205K, rebuilt with new shaft bushings, shims, felt, and new points/condensor.

So I've been through it all.. but very clearly missed something. I suppose it could be some trash in the tank. Just not motivated to make my garage smell like gas.

I had a sunroof Scirocco that leaked. We opened the roof, sprayed compressed air down the tubes and a bunch of stuff came out. They were clogged and it didn’t leak again.

I’ve owned 8 ACVWs and 1 water cooled VW in my day. Not one of them was perfectly water tight.


I’m assuming you haven’t pulled the gas tank during this process. Definitely an important thing to do. I would drain it and pull it. Remove the petcock, pull the screen (sock) and inspect the tank. Reinstall the petcock with a small hose that’s plugged. At this point everyone has a tank cleaning trick. I use acetone and a few links of a chain. Pour it in and let it sit for a hour or so. They shake the tank and get that chain moving around to break up any stuff that’s in there. Repeat process as many times as you wish. When you’re satisfied, dump it out and install a new sock.

I’d run a long solid wire down the metal fuel line that runs from the tank to the car to make sure there are no obstructions, then blow it out with compressed air. The line in ‘65 was clogged. Reinstall tank with new 1/4” fuel injection hose. If I remember correctly the hose would be 12” long and spiral from the bottom of the tank to the hard line.

Install a new New tank vent line, as stated above.

Good luck!!!

Oh yea, replace the speedo cable and your bounce should stop.

It's probably the sunroof that is leaking but it really can come from anywhere.

Sorry man! Sounds like a vent wing seal or the rear window seal. It has to be up in that area. Everywhere else is pretty protected.

I would park it the same way when it leaked. Then set the wife up with a hose and squirter. You then get inside the Bug and get somewhat comfy. Then have her shot the water up in the air, allowing the returning droplets to land on the car, to mimic rainfall. Then start searching for the water. Might take awhile, but you will find it!

Rich has it right! You need to allow some 30W oil to seep down into the cable. That is where the squeak happens. I have never seen a squeaky VW Speedo! Disconnect the cable at the Speedo. Stand the end facing up and the nut pulled tight to the end (I have the end of a Speedo for this, cut from a broken speedometer. Then fill the end with oil and let it dribble into the cable overnight. Might take awhile few nights. But the squeak will go away! Did this hundreds of times! I have never rebuilt a speedometer!

Feel your pain-never give up, never surrender.

Sunroof-yes, there are drain tubes that run down from the s/roof 'pan'. They must be clear and unbroken. Remove the rear seat and interior panels and you'll see them. Check 'em. blow them out 'upwards'...

Fuel delivery: start at carb and work backwards. Easy test is connect fuel inlet at pump to a 'coffee can' of fresh fuel with a long piece of fuel line.
If good, then you go under the tank. With the lf wheel off you can get to the outlet....

I think his main concern wasn't that it squealed, but it that it "bounced". To me, that points to a possible kink in the cable. Even a very slight one could be the culprit. But lubing the cable is always good to do as well.

When you replace the cable, consider changing its associated rubber grommet in the spindle too - it keeps water out of the wheel bearings on that side. I do agree a bouncing needle generally seems to be from a cable problem, whereas a noisy speedometer is usually a speedo lube problem.
