    James, This question is more suitable for the Z-Car Operations area of the forums. I have moved it to that location. It's inside the Carburetion forum. [m]

    This was posted to our old tips forum by Trevor: I chased gas fumes on my Z for quite awhile. When I had it all apart a year ago I replaced all the fuel vent hoses with the genuine Nissan ones and I kept getting fuel smell. Part of it was a leaking seal around the fuel level sender which I replaced several times and the last time I noticed that the tank built up pressure inside awfully fast while I was resealing it. I had never noticed any pressure build up when removing the gas cap though. I checked the valve in the engine compartment where the vent line hooks up. And although it wasn't hooked up exactly right, it basically hooked up to the air cleaner and the intake to vent the fumes it was also mostly plugged so the pressure was finding other places to escape like through the seal and around hose connections. Got the valve degummed and now I don't have the fumes or leaking problems anymore. -Trevor

    Found out that Nissan does NOT make gas tanks for the early Z-cars anymore. On discussion with some of the restoration specialists at the Z-Store, I found out a way to make my existing gas tank like new. It's a four step process: Boil the tank. Have it cleaned up inside and out. You can take it down to your local engine or radiator specialist to get this done. They will hot or cold dip it in acid to eat off all of the grime. Sandblast the tank. This can be done by the powder-coat specialist. Or, feel free to do it yourself if you have a sandblasting attachment for your air-equipment. Powder-coat the outside. Take the tank to your local (or maybe not so local) powder-coating specialist. Have them powder-coat the entire tank (outside only) in your favorite color. Also be sure to tell them that the thank has been dipped and stripped. Since the powder-coating process involves baking in an oven, some specialists get nervous about gas tanks. Gee, I wonder why?!!? :-) Seal the inside. Take the tank back to the radiator shop and have them seal the tank internally. This *MUST* be done after the powder-coat process. Since powder-coating involves high heat, a pre-sealed tank will be ruined from the heat. I guess the sealant bubbles on the inside. Now, I'm not sure if you can seal the outside of the tank after the powder coating has been applied or not. I wouldn't think it will hurt the powder coating to do this. Anyway, thanks to the anonymous donor for this information. I would publish the donors name, but, he probably doesn't want everyone calling him. I also saw a very nice article in the Z-Car Magazine about how to do this step by step. Check out their web site and get your own subscription for these kinds of tips. You can also order back-copies.

  5. You can read this, or visit the web page that I created at: http://scarab.240z.org/tips/tips_rack.htm The steering rack & pinion assembly unit is a pretty basic little setup. It consists of a small gear pushing a large bar left to right. The ends of the large bar are connected to your front wheels. This turning motion make the car turn left to right. Pretty simple explanation, eh? Well, that's how it works. Basics, get back to basics. If you figure this out, you'll be in for a nice life. Anyway, I wanted to share my experiences while looking at this little beauty. Why can't everyone benefit from my experience? It's also a nice way for me to look back at all the work I've done and say, "Whew! It's done!" The entire rack assembly mounts to the front mount bar. This is the same bar that the engine sits on top of. Therefore, engine removal is desirable, but, not required. Of course, I have all the correct tools to remove my engine in a few hours while the standard garage mechanic may not have this luxury. Well, I may not consider it a luxury. Anyway............. my apologies if some of this may be out of your field. The information isn't intended to be easy to perform. I did not perform a total rebuild on my rack assembly. I decided to cut it short of removing the gear mechanisms and tie rod knuckles. These suckers are $800 to rebuild for a reason! I cleaned the entire unit and tore just about everything else out of it. Okay, here we go. The parts that I used are: New steering rack boots. New polyurethane rack bushing mounts. New steering rack oil seal. Grease. New grease reservoir (from Nissan). With all of these parts in hand, and a previously removed steering rack assembly, I began my journey. Remove the old bushings. Use a screwdriver, knife, or whatever tool you need to pry the old bushings from the rack. Remove the old rack boots. You can probably do this with a knife or some scissors. Use a rag to clean up as much grease as you can. Clean up the outside of the rack assembly with a good degreaser. Remember, there is probably 20 years of grime on that thing! Just be careful not to get any chemicals into the rack internal components. Use a screwdriver and pry off the oil seal around the turning gear mount. This is the mount that the steering wheel arm connects to. Use extreme care not to bend the top of the seal. You might want to re-use it depending on its condition. Use a rag and clean out all of the grease you can inside the bearing housing. Now, take a some large pliers and loosen the locking nut (the large one) that sits around the slotted tension adjuster. Remove the locking nut. Remove the tension adjuster. SLOWLY remove the tension piston. Clean up the inside chamber and the piston workings. Be sure to keep the spring and washer positions noted. You can do this by just stacking them off to the side. You should be able to see the end of the zirk fitting and the bottom side of the rack inside the gear housing now. Clean it all up. Try to get a lot of the old grease out of there. Now take your grease gun and squirt some grease into the housing through the zirk. You should see the grease pumping in through the fitting. Be sure to fill the gear housing full of grease before you start the next step. Replace the tension piston by covering it with grease before you slide it into place. Make sure you put it all back together the way you found it. :-)

    Please bear with me while I complete this page during my rear-suspension rebuild. It's not complete, but, I will be adding to it later. You can find the page here: http://scarab.240z.org/tips/tips_rear.htm [m]

    How in the world do you get that shock cartridge out of the strut assembly? Well, you need to have contacts, or a nice wrench will do! :-) Your main goal is to release that top nut. It's a pain. It's a big pain. It's not easy to remove with vice grips, a pipe wrench, or any other standard wrench around your house. If it's stuck.... you can give up now. Do this. Take it down to your local Nissan dealer. Go into the shop area and bring the strut with you. More than likely, someone will approach you and ask if they can help. Point to the nut and tell them that you need to have it removed. Hopefully they won't rush you out. If they don't, they'll probably walk you to a large tool chest, pull out a cool looking "special tool," mount your strut to a vice, and proceed to remove the nut with one swift motion. All this time you can pick the grease out of your swollen knuckles -- because your pipe wrench didn't work. :-) Yes, I'm speaking from experience. I couldn't get it out and my tire store friends couldn't do it, either. They probably won't charge you (especially if they know you), because it will take less than 2-3 minutes to complete the task. Tell 'em you heard it here! [m]

    One more thing.... I like these forums a lot better than the Email list because the information is permanent. One question answered by many can help out a lot of other people down the road. In other words, most messages about suspension upgrades will only need to be answered once. Future "upgraders" will only need to look in the forum and review a similar thread from someone else. [m]

    Richard, These forums are still pretty new. They were put online around February 1, 2000. In our list, you will see a link at the bottom of every message to these forums. And, I plan to change the main web site to our new format. If you want to see our new format just visit http://scarab.240z.org Sorry, there is no spell checker (yet at least). To check topics, just click on the 240z-Logo and it will bring you back to the main Bulletin Board Forum page. From there, you can select the topics of discussion. If you aren't happy with the forums selections, send me your ideas and I will consider adding more. An ICQ number is part of a global-chat service. It's mainly a way of keeping a program running on your computer that will allow you to chat with people on demand. Visit their site at: http://www.icq.com I think you can change your own password. If not, let me know (don't post any passwords to this forum) and I will delete your account. After I delete it, you can re-create your account with a new password. I can't change passwords. As far as messages.... The Email list is completely separate from this Bulletin Board. So, if you want to stay in touch with the Email list... you'll still have to remain on our Majordomo mailing list. Maybe someday these forums will replace the Email list, but I doubt it. I'm sure there are people who will like to see both. [m]

    Back when I could drive my Z, I did the same thing. I replaced my stock header with a Motorsport 6-to-1 and 2.5" exhaust. My power increase was very dramatic. I could tell that the car was breathing a lot easier -- especially during acceleration. As far as noise... I could tell a difference. My car was louder, but it hummmed to a nice tune. Sounded strong and healthy instead of weak and choked. I can't give you scientific numbers, but headers are usually a lot better than stock (for the early Z's anyway) because they are tuned for the car. All the pipes are similar in length to create a balancing effect. Your other options include a 3-to-1 (6-to-2) header and a 2.25" exhaust. I have heard that the 2.25" exhaust gives you the same benefits, but it's not as noisy. IMHO: You can just buy a better muffler and use the 2.5" system. If you buy a header from the internet, make sure it has flange thicknesses that match your intake manifold. My Motorsport header had a thinner flange and it caused problems for me. The flange is used to bolt the header to the head. There are about 4 bolts that hold the intake and the exhaust header to the head (they share the same bolt). If one is thicker, the bolt doesn't fit right. Anyway, that's my $10 worth. I'd say go with a 2.5" exhaust and buy a good muffler. Definately go with the 6-to-1. [m]

    This story is also available on my home page. It was also created a long time ago in a galaxy far far away..... (that's my lame excuse to make up for grammatical errors) ------------- I first purchased my 1971 240z in 1989. I bought it from a family friend and he was the second owner of the car. The first owner of the car is also a family friend. So, I know where the car has been! Obviously, I am the third owner of the car and I'd have to say that I've pampered it the most. I have too much money into the vehicle to sell it. Plus, it means much more to me than the top value of the car (probably around $2,000). I bought the car after it had been sitting for about a year. The master brake cylinder was shot and the engine was blown. So, I replaced the master cylinder and towed it home (actually, my dad drove it through town with a blown head gasket -- but, we won't tell anyone about that). It then sat in my families garage for another year while I managed to fix the engine. To make a long story short -- I had the head rebuilt from Performance Specialties here in Corvallis. I then decided that the bottom end of the engine should be looked at. So, I took the entire bottom end of the engine over to Bob Forrest Engine Rebuilders (also here in Corvallis). He then tore the entire thing apart and called me into his shop to look at the damage. He took me into a dark-room and shut off the lights. He then switched on an ultraviolet light and pointed it at the engine. There were cracks in the block! Apparently, he put a chemical into the engine and forced it out through these cracks with high pressure. This test was able to confirm his belief that the engine had frozen over in the Winter! I needed a completely new engine. Well, Bob ended up finding a new engine block and we had to rebuild that one from the ground up. I'm sorry to say that the serial numbers don't match. That's the only drawback to my Z. Anyway, I had the engine completely rebuilt and also had Bob put on the fresh head from Performance Specialties (I eventually found out that Performance Specialties originally had Bob do the work on my head -- and they charged a profit on top of his work). So, I had a new engine. I was ready, believe me... I wanted to drive my baby. My dad and I transported the engine from Bob's place (after paying ~$1k) to our garage. We cleaned up the engine compartment, replaced the clutch, and hoisted the fresh engine into the old car. Now, you have to realize that we didn't end up doing this in ONE day! The entire engine "insertion" took us about a month. Weekends were just about the only time we could work on it efficiently. After we put the engine in the car, I had yet another chore.... I had to put it all back together. This, in itself, was a hellish nightmare. It was, after all, the first time I had ever taken that car apart. [m]

    Junior Member until you write 10 messages in the forums. After that, you become a regular member!! Whhoooo! Sorry, no gold stars. In fact, I could change it to 2-3 posts. That way "single message" users are still at junior status. Okay, I talked myself into it. Junior member status until 3 messsages have been written. After that, regular member kicks in.

    Oh yes, quite a lot of work But, it's worth it. I sure could have used something like this when I started to work on my Z-Car. I just keep remembering the "good ol' days" when my car actually ran. Heh. [m]

    Welcome to the Internet 240z-Club's new forum area! We are very excited to bring this to you and expect to see good results in the next few years. These forums were created with the thought that information can be stored and used by everyone who owns an early 240z or 260z. It's also nice to have somewhere to go when your Z-Car is acting up and you don't know where to turn. Believe me, when working on Z-Cars, it's much nicer to obtain help on a global scale -- especially when thse vehicles get older and a rarity on the road. Since these forums are new, you might have a few questions about how they operate. After you check the FAQ and new user pages, please submit a question to this forum. Your question should be answered within a few hours. If your question pertains to a specific Z-Car related item, take a look through our forums and make your selection based on that particular genre. For instance: If you have a question about the carburetion system, post a message in the "Engine & Carburetion Forum".... etc etc. You get the idea. -- Moderator Mike
