		What's a L28 worth?
		
		You can buy a complete engine with accessories (head, block, alternator, distributor, AC, power steering, manifolds, etc.) from the local PicknPull here in Oregon for $240. With a 30 day guarantee included. Electronic distributors are ~$42. That $300 is easy money IF you think you're done with the L engines. Otherwise, it's nice to have a known-good engine as a spare. http://www.picknpull.com/part_pricing.aspx?LocationID=119&Language=English&NavItem=3&SearchCriteria=partpricing

		Aftermarket Mirrors
		
		I bought a set of those. I just drilled holes where necessary. Use the plastic base a template for the holes to make sure it seats right, it shouldn't be difficult. They fit really well. I really like the way mine look. Much better than the old torpedo shape. Since we're giving opinions on esthetics. And having a passenger mirror is great, I don't know why Nissan didn't put one on originally. I did have one problem with mine when they arrived. One of the lenses was warped and gave a fun-house mirror image. I called MSA and the guy I talked to said he'd not heard of that before but they paid for shipping back and replaced it. I was only out waiting time. Check the image before installing. The one downside I found to the mirrors is that they're noisy in the wind. With the window down in the summer you can really hear it. I could cup my hand around the mirror and knock down the noise but it gets old after a while. If you have a quiet car and like to hear the scenery going by, they're a little irritating. I've had my eye out for better mirrors but haven't found them yet.

		1976 280Z Alternator Upgrade - Minor Issue/Battery Drain
		
		My old thread, back to life! If the rewire worked for a couple of months, I would have the battery and alternator tested, or test them your self by disconnecting either and seeing if the drain stops. A shorted alternator will drain the battery and a bad battery might not take a complete charge. And check the remaining wires from the conversion, one of them is hot all the time on the 76. It might be shorting to ground. No idea about the relays not affecting the brake warning light. Maybe Nissan moved the relays in 77. Odd. You did mention one other thing that's not quite normal - the voltmeter should be on all the time not just with the key on. But that might not matter. Assume that your car is normal and check the normal stuff for a battery drain, the battery and alternator.

		Starts right up, then falls on its face.
		
		The video sounds a little bit like low fuel pressure, from the fuel pump stopping when the key is let go. 78 uses the alternator or the oil pressure to keep the fuel pump running, either one. Maybe your switch is bad and/or the alternator is not kicking in soon enough. Watch your voltmeter and see if it jumps above where it sat before starting.

		Using Chevette Springs to Re-gain Original Ride Height
		
		How much effect will there be having the same rate front and back, compared to the lighter rate front springs in the stock setup?

		Starts right up, then falls on its face.
		
		Could be the auxiliary air regulator (AAR), It might be stuck closed. It's designed to let more air in for a few minutes so that you don't have to hold the throttle down or blip it. It's the torpedo shaped thing by the throttle body with a large hose connected to each end.

		arrrggh...clutch bleeding issue
		
		Here's a recent thread that's relevant. Opposite of your problem. We figured out the "magic number" - http://www.classiczcars.com/forums/showthread.php?t=47279&page=2&p=416109&highlight=clutch%20collar%20height%2092%20stack#post416109 If the collar is too short there should be lots of room for the collar to move back and forth on the front cover before it contacts the pressure plate fingers. Just another thing to maybe confirm your suspicions. I feel your pain, I took a transmission back out in less than a week after I installed it because it was leaking 2-3 drops of gear oil per day. The pivot pin threads in the cover hadn't been sealed. It had to be done.

		arrrggh...clutch bleeding issue
		
		The slave cylinder has a spring behind the piston that pushes it out to a certain spot and holds the rod tip against the fork. If things are right, the spring will take up all of the play between the rod tip and the seat on the fork, so that the next stroke give maximum travel. You can actually push the rod in to the cylinder to remove it if you wanted to, if things were right. It's fairly easy to take the slave cylinder apart, you might do that before you go too far. I think that there is a simple circlip holding the piston in. Maybe there's an obstruction in your slave cylinder. You could also take the rubber dust boot off of the fork at the transmission and get a better feel for if the fork is seated on the pivot pin and held correctly by the springs. And somewhere out there I have seen a diagram of the angle of the fork when it's seated properly. If the fork is on the pin correctly, it will have a little bit of play fore and aft but will be held firmly by the springs. If it's not held by the springs you'll be able to tell. It's hard to feel with the boot on though, you'll need to pop it off (it's hard to get back on though). Just a few ideas before you take it out. And, by the way, I think that you're using engage and disengage backwards. Engage is when the clutch pedal is up and the engine is tied, or engaged, to the transmission. Disengage is when the engine is released from the transmission by pushing on the clutch pedal.

		Aluminum foil inside injector port.  I feel stupid.........
		
		Following Tomohawk's suggestion - the first thing you should do is see if the intake valve for that injector port was or is open. If the valve is not open, then the foil piece is probably sitting there waiting to fall in if you turn the engine over. If the valve is open, it might still be sitting on the back of the valve head. With a bright light you might be able to see it through the injector port. You might be surprised. If you can see it, rig up a small diameter vacuum hose so that your shop vac pulls a vacuum on it and suck it out like liposuction.

		Steering Wheel Clamshell Screws
		
		They are self-cutting, or -tapping, and cut their own threads in the plastic when first used, I believe. Very coarse thread. Similar in pitch to the self-tapping screw shown in this link - http://www.bbc.co.uk/schools/gcsebitesize/design/resistantmaterials/jointsrev2.shtml

		Harmonic Damper problem
		
		Here's a "while you're at it" maybe - if you have had any thoughts about going to an alternate ignition or engine management system, like Megajolt or Megasquirt, add a 36-1 wheel to the damper and pulley before installing.

		arrrggh...clutch bleeding issue
		
		Sometimes the bearing will come installed in the collar. With those parts you probably need the tall collar shown on this link - http://zparts.com/zptech/articles/trans_swap%20parts/4tobear_specs1.html Did you install the parts or did someone else? I had a very similar situation, way back with one of my first cars, when I put the clutch disc in backwards. The hub springs were jammed against the flywheel bolt heads. Unlikely for you, just an example of how things can go wrong. Also, if your slave cylinder is leaking, you'll probably have some fluid inside the rubber cover. The cover seals pretty tightly and will hold quite a bit of fluid. Watch out if you decide to peel it back and take a look. I had a leaking slave cylinder (Schucks-bought) and it had your symptoms.

		'78 Clutch Engagement Issues
		
		Have you checked the clevis assembly for play and wear? If I was installing a clutch MC, knowing what I know now, I would eyeball the relationship between the clevis pin holes and the pin hole on the pedal before I inserted the pin. The MC has an internal spring that pushes the piston out to where it should be in the cylinder. If it's pushed out too far, you'll run out of travel in the cylinder, if it starts out too short, you'll run out of travel on the pedal. The starting point should be to have the clevis pin holes lined up before inserting the pin, then fine tune it. If the pedal is at the top of its travel and the MC piston is at the start of its stroke, that's the maximum travel you'll be able to get. Easy to verify by removing the pin and seeing where things are. Might have to use a mirror. There's probably a stop screw under the pedal also that can be adjusted. One more thing to check.

		Mustache Bar Bushings (rubber)
		
		Did you replace the bushings or a shop? Even after 18 months it should be fairly easy to recall the rubber piece that was burned or hacked out of the mustache bar to install the urethane bushing. To install new rubber bushings you need to cut out the metal sleeve of the old bushing that was left behind, from the mustache bar. The Rear Axle and Suspension chapter of the FSM has a drawing of the cross-section of the bushing and the washers. If you can't figure it out, post a picture of it here and someone can probably walk you through it. Edit - Thank Blue for making it easier...

		Harmonic Damper problem
		
		What brand and model so future damper replacers can avoid the problem? Did you install it yourself or have a shop do it? Just curious about any installation problems. I know that MSA's damper is often too tight to install without modification.

		Engine rebuild
		
		I tried datsun parts, "datsun parts" in quotes and datsunparts as one word in the search box and didn't get anything worth reading. I think that Chris Z is suggesting that datsunparts llc might not have a good reputation. Probably worth checking out before buying, especially for a big item like an engine.

		Fusible link update
		
		The wire size and color are shown in the Body Electrical chapter of the FSM, in diameter not gauge. The capacity of the links commonly referred to for the fusible links "upgrade" is apparently based on estimates. Not trying to stir up old discussions, it's been discussed in depth before. It's just the state of the situation, anyone modifying their car based on internet information should verify veracity and is ultimately responsible for any problems incurred.

		Car won't rev/idle pass 3k " Video"
		
		Not sure why there's two threads now but the video worked great in this one. Your engine sounds almost exactly like mine did when I installed the plug wires in reverse rotation order. Then engine will start, even though, by firing order, it's only running on two cylinders. Maybe another cylinder or two gets enough timing to fire also. Anyway, I would re-check firing order and rotation - 1-5-3-6-2-4 in counter clockwise fashion.

		Car won't rev/idle pass 3k " Video"
		
		Your video is in mp4 format, which my computer won't play. Is the problem no load, or while driving? What year car? Is it stock or has it been modified? Why did you install a thermostat housing? What all did you remove when you were working on the housing? Just a few questions that might help in figuring out the problem. Idling funny and "farting" sounds like a miss, which could be vacuum leak related or could be low fuel pressure or misplaced plug wires. Edit - actually Windows Media Player did open it and play it, but without the sound. Which doesn't really help.

		Suspension advice needed
		
		I screwed up way back when I said that I had 5020's for my 280Z. I have 5022's, which are the 280Z springs. Sorry for any confusion.

		arrrggh...clutch bleeding issue
		
		There are many possible combinations of pressure plate and release bearing collar, some work and some don't. Can you describe the collar and pressure plate that you are using? Your hydraulics might be fine, it could be the other parts.

		Voltage regulator???
		
		The mass of relays and square metallic objects and wires and connections near the VR can be confusing. It sounds like you or someone else might have installed the wrong alternator on your car or you have the right alternator but should have replaced the external VR instead. 75 used an external voltage regulator. If you use the internally regulated alternator you have to disconnect the old VR AND install some jumpers at the VR connection. You should get 10% more sure, to 100%, of what you have. There are drawings of the VR in the Electrical chapter of the FSM. The location is shown in the Body Electrical chapter (use the 76 FSM if you need to, the 75 xenons30 link doesn't seem to have that chapter). Also, your ammeter will tell you if the alternator is producing. + is amps going in to the system, - is draining out. The atlanticz link might help you help you out too, with pictures from a 77 280Z - http://atlanticz.ca/zclub/techtips/alternatorswap/index.html

		What is my car worth?
		
		Diode. But if they installed the late-model alternator in a 240Z without installing the diode, they may have also installed it without disconnecting the external regulator. Better check the whole charging system.

		cold start valve,
		
		Many manufacturer's offer a cheaper part but give a shorter warranty. That is probably the main difference. The cold start valve's only purpose is to squirt some extra gasoline in to the intake manifold when the key is at Start and the engine is cold. Many people remove theirs to remove one potential problem. I've removed mine and don't even notice it's gone. I live in Oregon where it rarely gets below freezing though. If you live in Minnesota, you might want to keep it.
