Hi guys im wondering if any of you know the function of the metal bracket that is held in by the oil pan bolts on the driver side?

Is it okay to remove it? any use for it? thanks for any help

Hello Z family, ***Disclaimer I am completely new to the older Z world. I have an 03, 08 nismo now the papa 240z. *** I purchased the Z feom BaT. Car started and drove perfectly. Under throttle and idle. It had a straight 3" exhaust and I could not take the "noise". I swapped the headers and exhaust for the Zstory system. Header through to the twin muffler. I took the car out for a drive and giving it throttle it starts to cut out around 5k and then shuts down. I restart and the same thing. When I first got the car home I was driving around town 30+ miles. Car shows Breakfast cruising. Loud cruises. But no issues at all. Cars fuel level would be ab…

I'm working on doing a brake fluid flush on my 1977 280z. I just finished bleeding the master cylinder and I went to the rear drums next. When my fiance pumped the brakes and held down the brake, I noticed that the line right below the hole to drain the fluid is leaking. It was never leaking before until now. It seems to be leaking right before the nut which attached to the drum. How can I stop this leak?

Working on my new-to-me 72 240z today. Successfully replaced the right side steering rack accordian boot today. Started on the left side boot. The jam nut refuses to back off, threatening to round off the nut points. On the right side, the jam nut has a right hand thread. On the left side, is the jam nut rotation direction reversed, as in a left hand thread? Thanks!

Hi, right now i am in the process of fixing all small issues with my Fairlady. Since you guys already helped me I want to try my luck a second time. I had a look at the vacuum lines and to me they seem to be set up in a weird way. The car is a '78 280Z with a 280ZX engine (L28E F54 block with P79 head) converted to Ztherapy SU carbs and original AC. The engine runs fine apart from a slight fluctuation in idle speed (every 3-5 second it goes up from 800rpm to maybe 840rpm and then back down again). I checked all the FSMs to use the correct terms in my drawing and I added three pictures of the current situation. Especially the wrong plumming of the servo diaphragm and c…

My 74 260z has dual Weber 32/36dgav with emissions and mechanical fuel pump delete. Car runs good at idle and on throttle. The problem is cruising around at a constant speed it has a "mis"/bubble spot the it seems a cylinder isn't firing. I have new plugs wires and distributor cap and rotor. I noticed taking off the plugs the NGK caps for the wire connection unscrewed itself from the porcelain.(possible fix) The cylinder 6 has a dark plug but the rest are a dusty clean grey. The cylinder 6 exhaust bolt is snapped in the block and definitely has a leak. Brand new fuel filter put in last week. I also have never owned a carb car before so my tune is iffy and I'm going to loo…

Hi everyone! So over the past year and a half I have torn my 1974 260z with an L28 and flat top carbs down to it's rusty britches and done my best to get her nice and shiny. This is my first project car, so I probably have no idea what i'm talking about. However, I have not been able to get the car to start and I am pretty stumped, even though the car ran when I bought it. FYI, I did disassemble the engine, clean it up, refresh it with new timing stuffs etc, and put it back together citing the FSM almost religiously. I also have been wiring the car myself using the speedway 22 circuit harness + some custom over engineering bits. So far: Brand new battery …

I'm confused about where a hose goes or if I got the wrong hose for my tank. The attached 3 pictures showing the hose, an illustration of the hoses (I think this is hose #5), and a photo of my tank with the connector circled. I think this is the right hose for this connector but the hose diameter is <1/2 inch and the tank port is maybe 5/8th inch. Where should this hose actually go? My car is a Jan' 74 260z.

1976 280z rough idle then dies.

Need some help on what to do next, here's the story so far. 1976 280z California edition (manf. date Sept.1975). Bought the car in late Jan. 2019, car passed emissions test and it started and drove fine until 2 weeks ago when problem first occurred. Engine runs very rough for about 1-3 minutes at high RPM when gas pedal is pressed, and exhaust kicks out white-ish / light gray fumes. When gas pedal is released, engine dies, car will not idle. Try to start again and engine cranks but will not start. Let it sit for 1-2 hours and it will start again, same as above. Makes me think it is flooded with gas and needs to sit before it will start a…

I have yet another question for the gurus in this forum. I pulled my transmission to replace all seals/orings and found what seems to be "a lot" of play in the input shaft. My semi-accurate measurement technique shows around 0.045" of play back and forth. Is this normal. None of the manuals I have give any sort of measurement on this. The car has 125K miles on it. Thanks!

I'm in the process of converting my 72 240 from a 4 barrel holley back to SUs. I've read numerous articles on the pros and cons of heating the manifold and I think since I live in New Hampshire where every morning is cold I want to heat them. Ideally I would have the manifold heater thermostat that was used on the later 72 models and beyond to avoid the potential issues with continually heating them. Anybody know where I can get a thermostat and the associated piping? I'd like to think I could get an old one to work again with some TLC. I found a part number in a different forum for a possible alternate but it looks like it is no longer available. Any thoughts / ide…
