CG240Z

Adjusted the AFM by using the beer can method on the Atlantic Z website, it was a little off, so I adjusted it. Put the AFM back in and cranked the motor. Still popping out the exhaust, running rough, and not idling. I left the cover off and played with the rotating mass as the engine ran, doing this I can get the engine to idle. So maybe I didn't adjust it enough? I'll look into that some more. At one point I was adjusting the timing and messing with the AFM to see if I could get it to run any better. Not much success. I might have stumbled across something too. I'm not sure I'm running on all cylinders. I pulled the fuel injector harness on 6th plug and the engine didn't change much. I then pulled the plug with the fuel injection connected and I didn't notice a change. It's getting spark, I could see it arch when I put it close to the plug. This might be another avenue to look further into. Hanging the can, you can't tell in the picture, but the can is hanging. <a href="http://s254.photobucket.com/user/taillonml/media/280z/C1CD5374-9970-4495-B2E0-59BDBD759133.jpg.html" target="_blank"><img src="http://i254.photobucket.com/albums/hh101/taillonml/280z/C1CD5374-9970-4495-B2E0-59BDBD759133.jpg" border="0" alt=" photo C1CD5374-9970-4495-B2E0-59BDBD759133.jpg"/></a> <a href="http://s254.photobucket.com/user/taillonml/media/280z/C910DDFF-06FA-46C9-8A42-CF912C2A6D26.jpg.html" target="_blank"><img src="http://i254.photobucket.com/albums/hh101/taillonml/280z/C910DDFF-06FA-46C9-8A42-CF912C2A6D26.jpg" border="0" alt=" photo C910DDFF-06FA-46C9-8A42-CF912C2A6D26.jpg"/></a>

Awesome picture Eurodat.

I ordered a fuel pressure gauge, should be here by Wednesday. I put a new fuel pump in the car, but it's just an Autozone special, I'm curious to see what it's doing.

I'll check the timing. I've set it before with a timing light, but you know how that goes. It could have shifted. Thanks for all the ideas, I have lots of avenues to explore.

I did check the lash pads, thinking maybe that was it. I called Web Cam where I bought it from and asked about it. They said as long as I can get .008 and .010 my lash pads are fine. Tight tolerances, but that's what it calls for. Good idea on fuel pressure, I'll need to pick up a gauge.

Nope, I still have the mild performance cam in. Hopefully that's not the root of the problems. I'd like to get the AFM cleared before I go swapping cams. I'm waiting on Lenny's new ecu to come out, I'll put that in too to help compensate for the cam.

Working on this bad guy tonight. Going over the tech tips from Atlantic Z and EFI manual to try to figure out if this thing is calibrated or not. I'm hoping this is the key to get the engine running better. <a href="http://s254.photobucket.com/user/taillonml/media/280z/F6065827-574E-453C-BAE5-94149AB06148.jpg.html" target="_blank"><img src="http://i254.photobucket.com/albums/hh101/taillonml/280z/F6065827-574E-453C-BAE5-94149AB06148.jpg" border="0" alt=" photo F6065827-574E-453C-BAE5-94149AB06148.jpg"/></a>

Congrats! Great news.

Sad to hear, I've been there too. My 1970 240z also literally blew a hole in the side of the block with the #2 piston.

I believe the engine is running rich, not lean. I haven't pulled a plug to confirm, but I can smell the gas while the engine is running. The car didn't run right before the move, it's been backfiring since it's first start. It's a new cam so I shouldn't have any flat spots. But it just hit me, I'm running stock lash caps, I wonder if the cam calls for a different lash cap. I am going to call the company I bought it from this week and find out and also double check on the valve clearances with them. I still need to double check the AFM, just didn't have the energy to pull it out today. Once I get the engine running, I need to get my clutch issues figured out. After that she's ready to hit the open road for her first test run.

Many moons later I'm settled into the new house and the Datsun has it's new garage. Got to do some tinkering on her today trying to get the engine to run smoothly. I did a valve adjustment and she's still back firing and will barely idle, if any. My next thought is too check the AFM to see if it's calibrated correctly and go over the vacuum hoses again. At least she looks good in the garage regardless of if I can drive her. Just pretend the Ford Racing flag says Datsun Racing. <a href="http://s254.photobucket.com/user/taillonml/media/280z/E281F1C6-ED9E-4566-AEA3-3EDE5AFF8D30.jpg.html" target="_blank"><img src="http://i254.photobucket.com/albums/hh101/taillonml/280z/E281F1C6-ED9E-4566-AEA3-3EDE5AFF8D30.jpg" border="0" alt=" photo E281F1C6-ED9E-4566-AEA3-3EDE5AFF8D30.jpg"/></a>

I didn't realize we started a new thread. I was wondering why the old thread got so quiet. None the less, sign me up for an ECU!

Thanks for the help! Lots of useful information. Can't wait to get working on the car again and seeing if I can get this problem ironed out.

Hopefully someone will be able to help me out on this. I have a 78' Z with an 83 5spd trans. I'm having problems getting the clutch adjusted properly. It's either slipping or won't disengage. I can't seem to find that happy median. Something that might be causing it is, even with the clutch M/C rod adjusted all the way out, the pedal still isn't returning to the pedal stop. I looked in the service manual and confirmed that the pedal height should be greater than what it is. I installed a new Autozone M/C and clutch in the car and have read that the rods can be too short. So I pulled it back off and compared it to the M/C that was on the car, same length rod. Also, when I do have the clutch adjusted to where it somewhat engages/disengages, it only actually works the clutch at the last 2 inches of pedal movement. I bought the car non-running, but I'm assuming the clutch pedal should have an even feel the whole way. Not "nothing, nothing,nothing, engage". Any advice would be great. This is one of the last hurtles keeping my build from getting on the road. Thanks guys!

Figured I'd give my thread an update. Hopefully close on my house within the next 2 weeks. It has a decent sized 2.5 car garage, which isn't very common in San Diego. Can't wait to get the garage setup and the Datsun unloaded. I'm ready to hit the open road in it.

I had a 2+2 280z that somewhere along the line had a sunroof installed. Doesn't seem to be a terribly uncommon add on people do. I'm not a fan of them, but that's just personal preference.

Do you really need oil temp? I had it on my Vette and it was nothing more than a cool factor. I'm not so picky with this upcoming ECU. I'm just looking forward to my engine running better and to be able to monitor the main sensors on my laptop.

Great updates! Exciting news. Can't wait, maybe you can make some money off this and consider moving somewhere a little bit warmer. Haha.

The skins look great. Can't wait to be monitoring all my gauges on my laptop. (Which I will also have to buy. Haha) Then I will really be able to see how my engine is running.

Thanks! I enjoy sharing the restoration experience with others. There is still a lot to be done, so keep following along! I'm still looking for a place to live, so until then work has taking a temporary break.

Thanks! I'm still looking for a place to live. I'm itching to get back to work on the Z and hit these California roads.

I didn't realize how long it's been since I've done an update. A lot has happen to the car, I'd say it's about 90% done. Got the engine fired up, but she's running really rich. I need to double check my vacuum lines, check the AFM, and do a valve adjustment. Engine has only has about 30 mins of idling time on her. The clutch needs some more adjusting. At first it was slipping, then I couldn't shift gears, and now the car will move, but once I give it gas the clutch just slips. More on that later..now for some pictures! Restored spare tire looking great. Modified the false floor so I now have access to the storage compartments. It came out perfect. You can't tell that the front part flips up. Perfect for storing random things. (Picture is before I installed the center console and finished painting inside the compartments) The seats and interior are looking great. (Rear hatch weather stripping fell down) I really like the rear end with the smooth bumper. Exhaust looks great too. Here's some shots of it on the lift. I don't have too many photos of the finished product yet. And finally the car loaded up in the trailer. I'm moving out to San Diego. Progress on the car is going to have to go on hold for a bit until I found a place to live. Can't wait to get back to working on her. She's been registered and insured, just needs a few more adjustments and she'll be ready for her initial drive.

I'm going to try some more speedo and welding wire action. The tank has been sitting since 95 before I got to it this year, so it's definitely gummed up.

I like the blue, looks good.
