70/71 datsun 240 Z

On Rockauto, there is a couple condensor's listed as for dual points cars (The automatics). As long as you ordered the primary condenser (Which is the same as the manual transmission confessor),...

So it's not just me with the horrible throttle modulation off of idle? I've only driven my Z around the block, but I swear if it were wet out, the tires would be spinning every time I hit the gas...

After watching "Just SU's" for the first time, your symptoms are describing a leak in the throttle shaft to a T. I'm a novice for sure, but from watching the video that is what he describes exactly.

Well, I think i'm going to go with MOOG universal 1" sway bar mounts. I stripped, etched/primed and painted the bar today. I then test fitted the sway bar end links I had purchased for a 240z...

Wow! Your doing the body work yourself! Great effort, gives me some hope after all!

2 choke cables would definitely make sense. But I am missing one in the cabin, but there is a spot next to my choke(On the centre console) which looks like it could house another(I was always...

Vancouver BC. I'm slowly making my way through the tune up procedures. After installing all the ignitions points etc the car was idling very nicely. Unfortunately this seems to have changed as it...

I should also note to Blue. The car is still not drivable, so I believe a lot of the carbon buildup on the spark plugs is due to extended idling, as the car has not been driving or been run for...

Blue, I agree. The other plugs definitely show a rich mixture, but with the one that is quite a bit more lean, I was concerned before I try and tackle another issue.

Yes, the vehicle is still...

We have spark… Hmm

Oops, sorry. I always forget to add the details. 1971 Datsun 240z with SU's.

The plug is very grey/white, even though the picture may not show it. The remaining 5 are definitely black.

I'll...

I was just searching online about general advice on this subject from other vehicles, and noticed someone mentioned if water was getting into the cylinder then it could cause this. Recently I...

Or, 5 rich…

I pulled the plugs today and noticed the cylinder closest to the firewall (6 or 1?), was much more lean the the other obviously over rich(Just black), cylinders.

What could cause a...

Changed the oil and it overfilled an 8 liter(quart) pan. Not sure how much was really in there….

Gorgeous. The Roadster was my first true Datsun love, but I found my clean 240z first. A little jealous.

Here it is. I apologize, I can't for the life of my figure out why my photo's get posted upside down. I even try and flip them and it does nothing.

^ Thanks for the suggestion. I didn't end up getting paint or POR as I was unsure of a primer. So this info is greatly appreciated. Wire brush is cleaning it up nicely. Although after picking up...

Perfect! I couldn't remember what the units were. Thanks again!

Hello,

Just swapped out the points, cap, rotor, and 1 of the two condenser's on my 1971 240z.

I couldn't unscrew the "automatic" condenser without some clever contraption without taking the...

Thanks for the advice. Removed the sway bay today, will pickup a wire wheels and some paint today to tackle this project. Powder coating is not going to be an option this time around.

1971 240z L24 w/E88 head. Stock, SU carbs

Thanks for the picture rotation!

Good to know it's possible it could only be a coolant leak. I guess the only real way to check is to do a compression test?

Is there any other heads I could...

Looks like I have a coolant leak between the head and the block, right near the back of the engine, close to the transmission.

I'm assuming this is clearly a head gasket? Not having much luck...

Hello,

My Front sway bar end links and bushings arrived, and I thought I might as well try and sand the bar down (I don't have access to a sand blaster) and give it a quick shot of paint.

Any...
