  1. But it does discredit the "only in America" statement. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>

    And there are cars here that came from the factory with only catalytic converters and no mufflers.

    Legality is about DB limits, and my car is legal, and actually pretty quiet as you can hear from the frontal shot and interior shots.
     
  2. Dodge SRT4 Neon is a prime example.

    The finish quality isn't quite the best but actually I was thinking on something with wider tubing and more direct flow. No need for so much tubing mess! Of all those in that site, it actually was the best IMO...

    As for the muffler regulations, what I ment about "only in America" is that, apparently, it's legal to have un-muffled cars. In Europe, it's not, since our noise restriction laws are tighter. That's why most of the american cars imported have to suffer specific modifications or have specific specs for Europe. I remember Viper and Corvette as examples but there must be more.

    If a straight-four needs to be muffled, why won't a V8 have to? The legal limit is 92dB here...
     
  5. THe Baja Bugs have the exhaust outlets in a different location than the "regular" bugs? Didn't know that (my bad).

    Yeah, that'd be niceee! I'm curious about that exhaust...
     
  6. Yes, the Baja Bugs generally have the outlet pointed up toward the sky since there's no body work in the way. Then it isn't hanging low to get snagged on something on a trail. When you have the full rear body work of the standard Beetle, the outlet has to come out below the bodywork. I found a couple of examples of the Baja-style stinger and then there's an example of the dual exhaust that looks similar to what you were sketching up.
     
  7. Sweet... :D

    I'm not much of a 'cruising' car guy, but I'd been looking at these recently, and after hearing yours I'm loving the noise. What are they like to drive through some corners? Obviously fairly good, but enough to entertain someone who likes lightweight cars but kinda wants more room?
     
  9. They feel smaller the faster they go. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A> I didn't buy mine with the intent of having a sports car, but it's been pretty good. The Sport optioned versions are teh best, naturally, but you can add good prings and shocks to the regular ones, as well. And, of course, good tires help.

    That sounds nice. One of my friends will be over this weekend with his video camera, so we'll get a short video of the Bug.
     
  11. That's hot
     
  12. Well, I got the left front wheel bearings changed (turning the front wheel sounded like a miniature ball mill or something) and the brakes adjusted on Saturday. I also adjusted the angle of the muffler so it tucks up toward the fender a little better. I put in the rear engine tin (doesn't fit quite right, but it will work for now) and used a huge hose clamp to temporarily fix the alternator mounting strap (I'll have to take pictures of that one). I was going to drive it to the DMV and get it registered Monday morning, but I had a 10:00 meeting that I didn't want to risk missing and there's no way I would have driven it to work (15 miles) until I got it registered.

    So, I drove the Bug for the first time today... it was only to the DMV, but still. Now the paperwork is in for the registration (special interest vehicle) and title. So it's all legal-like now. Unfortunately, on the way to and from the DMV, I started blowing a boat-load of smoke out of the tail pipe. It didn't do it consistently, but when it did, I had a good smoke screen behind me. It didn't run all that great either. It didn't run bad, but definitely not running like it should. So, I'll need to figure out what's going on there. I noticed some oil coming from the head (between the head and the cylinder), so I'm wondering if somehow the cylinder head nuts backed off the studs.... hopefully it's not the studs pulling out of the block.

    And yes, I'm positive that it wasn't just oil leaking onto the exhaust causing the smoke... I could see it pouring out of the tail pipe and when I got home the inside of the tail pipe was oil-soaked. I had been planning on driving it to work today, but I just decided to drive it home and take the GTI. Maybe the "big" engine build will have to happen before I was planning...

    My friend Mike was down this past weekend and took some video and posted it to youtube. I'll send the link from home... youtube is blocked here at work. It sounded pretty good this weekend, but you can still hear that something isn't completely right (I was thinking carburetion and timing sounded and smelled a little off). I'll post more explanation when I post the video.
     
  13. I cant believe you ruined my engine the first time you drove it! <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>

    Tell me one thing: the oil you had in the exhaust was liquid or already burnt? Cause I had a similar problem with my car and the problem is that the piston segments and part of the piston's head had been punctured by a faulty spark plug (which was makig contact between the pole and the piston instead of the two poles). That would cause the car to stutter quite a lot at low speed and it would make quite a lot of smoke. But in your case, if it isn't making it consistently, it might not be the case. IMO, it could be one of the piston segments that has collapsed and some might be squirting out to the combustion chamber.
     
  14. That's what I think is happening... the head could be slightly loose on the one side allowing the cylinder to shift just enough to let oil by the rings. It's probably going to be a few weeks before I get a chance to work on it again. My wife is getting tired of me leaving her with the kids on Saturdays while I work on the car (I'm only out in the garage, but still)... so the investigation will have to wait for a while. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>

    The oil in the tailpipe was pretty wet, so there was some significant blow-by. It wasn't just carbon deposits from running really rich or anything.
     
  15. Hmmmm... if it's liquid, it isn't passing through the combustion chamber. I mean or it is and it's quite a large leak (enough to half of the oil to be burnt and the other half to be exhausted fluid and still soak the piping) or it might be the valve cover gaskets or something. But there were carbon deposits too, right?
     
  16. The oil has to be passing through the combustion chamber... otherwise, it wouldn't be on the inside of the tailpipe. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>

    It was definitely burning the oil (hence the smoke), but enough was getting through unburnt that the inside of the tailpipe was pretty wet.
     
  17. Well, not forcingly. It could be, as I said, lubrication oil form the valve tappers that was leaking to the exhaust mainfolds. But yep, if it's smoking, it's burning! Haven't you sensed a clear lack of power? I mean, I'm guessing you haven't driven it yet but surely the car was running lazyer than expected from a car like that... and uneven acceleration/throttle...?
     
  18. Yes, the oil that was dripping onto the OUTSIDE of the header could be a leak from the valve cover, but the header pipe is too far in toward the center of the car for the valve cover to drip on it. The drips appeared to be from between the head and the cylinder. The oil on the INSIDE of the tail pipe (far from any possible drips) had to come from the combustion chamber.... how the oil got into the combustion chamber is the mystery. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/wink.gif"></A>

    Yes, it was running a little odd when it would smoke... definitely misfiring, but how far down it was on power I wouldn't know since I never drove it beforehand. It seemed more powerful than my old '74, but it's been about 10 years since I had that car... I think part of it was my '74 was a good 200 lb. heavier...
     
  19. Almost certain it's one (or more...) of the segments that's ruptured. That way you lose compression and the oil from the sump will enter the combustion chamber whan the piston is on its descent. Not expensive to fix if done in time (and watch the oil level, my car did that and if I wasn't careful enough it would become dangerously dry; never gripped though).
     
  20. What do you mean by "one of the segments is ruptured"? Like one of the piston rings broke? That could very well be, and would be a pretty easy fix. I really doubt a leaking valve stem seal would let that much oil into the combustion chamber, especially given how the head and cylinders are laid out. The thing I was finding odd was not necessarily the oil inside the exhaust, but that I also had oil dripping on the outside of the exhaust from the head as well. These engines don't have a head gasket like water-cooled engines, so the only things I can think of for the oil leaking from there too is either (a) the head studs are loose or (b) I have a cracked cylinder head or cylinder. I guess we'll see when I get a chance to tear it down.

    Part of me thinks that if the engine needs a rebuild, no matter how minor, I might as well just save up for the bigger engine build. But then the other part of me thinks that I could live with the smaller engine for quite some time, so a very basic rebuild would be all I need. Meh.

  21. Yeah, that's what I meant. The piston sealing rings...
    I hope it's not a cracked head or something. In that case, I'd go for a new engine instead of a rebuild. At least you wouldn't spend the money for the rebuild plus the new engine anyway.

    Bringing this back from the dead in case people are curious about the exhaust sound.




    Also, I drove it to a VW show a couple weeks ago and it ran fine. It did start smoking on the way home though and it looked like it was coming out from all over. I got her into the garage and there was oil dripping from the tins onto the header.... so maybe most of my smoke was a leaky oil cooler. I'll tear into it one of these days. I don't drive it much at all...
     
  23. looks/sounds great
