I have a 76 280 4 speed. was working fine when i parked it last summer. the other day went to start it clutch peddle went all the way to the floor nothing there. checked the fluid it was low so i added some no luck. last night tried to bleed it when i opened up the bleeder nothing came out even when my son pumped it. so was thiking master is shot .but after reading some on here and looking at the slave my question is the slave and fork. should the slave piston be out that is how it is was thinking it should be in then when you push on the peddle it should come out.

Long story short, my engine was making an intermittent ticking, opened it up to make sure a valve hadnt gone lose form an adjustment I did a bit back and realized my #5 valve spring was completely extended, as in, did not stop pressing against the rocker arm even when the rocker arm was completely "lose" so I brought the exhaust valve next to it all the way down then counted the turns to get it adjusted to the right level for the other one that I could not adjust. Adjusted the other one to that point, then set the good one to its correct position and threw it back together. From my understanding of how the valves work, the only way that would happen with the spring is if …

Finally starting the LS1 swap guys. I'm removing the triple webers and engine and will be getting rid of those to help fund the rest of the project. You have to appreciate how easy it is to drop one of these engines compared to a newer car. The car and engine I am starting with has about 90k on it, so I'm a little sad to be pulling it apart, but I plan to completely refinish the whole thing, so I'm dropping the whole drivetrain and getting it up an a rotisserie to start body work. Wish me luck. Phase 1: Remove triple Webers and intake. DONE Phase 2: Remove exhaust. DONE Phase 3: Remove transmission Phase 4: Remove engine (lift point suggestions, anyone?) Phase…

I just finished replacing all the bearings and inspecting all the synchros in my 1982-83 five speed. I assembled it all in the vise, but without the case yet. The case is off so I can test it all. It shifts though the gears nicely on the bench, and all is smooth...except when I engage reverse. When I engage reverse, it is difficult to spin the input or output shafts by hand, there is quite a bit of drag. It spins with a wrench on the splines but it feels like there is a lot of drag. Possibly the 5th gear synchro dragging?? When in reverse, if I force the reverse shift rod 1/16" forward or backwards against the detent, the trans frees up perfectly. It's almost as…

Hi Folks, I cleaned my spark plugs and noticed all were ok except No.1 that was wet with oil. Engine has decent compression and runs smooth as silk. Car has been sitting for about six months. Could it be I have excess oil that has creeped into the cylinders due to a bad valve stem seal? If I rev it at idle it will smoke at 3000RPM and then clear up. I'm guessing I should drive it for awhile....any suggestions?

I pulled the oil pan tonight to fix a gasket leak before I get it back on the road and I found a milky goo in the bottom of my pan. The car did sit for about a year prior to an oil change and restart. This scares me. Little more info. This is a new build. I had the head and block redone by a local shop with lots of Z experience, but I did reassemble it. The car runs (sitting still) pretty darn good with no smoke of any kind. I've run it long enough to watch the temp and idle settle, but I've never ran it for longer than about ten minutes. Been working on it for about three years. The oil I drained does not smell of anti-freeze or anything else. The pan does smell a littl…

I got a full clutch assembly, stage 2 I believe, from and sr20 (s13) and I was just curious if it would fit in my stock 260z? I have an offer to buy my whole sr20 engine and I was curious if it was worth keeping that for my Z. Thanks for the help!

It's the lock pin which holds the striking lever to the striking rod. See this pdf pg 4: http://www.jdmgallery.com/wp-content/Datsun/70-78/1978_280z_FSM/MT%20Manual%20Transmission.pdf I had trouble getting it out as fastd did from his post of a couple weeks ago, however I handed the whole assembly off to a technician friend before I cut anything up. I did try drilling into the "head" of the pin and even a small hole through the lever itself all in hopes to relieve some tension of the hold the pin had on the surrounding parts. So here I am hoping (reasonably I believe) that the lever with its little hole is still reusable but I'm looking for a new lock pin. Anyone know how…

Hey guys, new to the forum just purchased a 260z 2+2 74" and it has a dogleg transmissión 5 speed. I'd like to know if there is anyway of telling where it came from? What car? Year? I have zero experience on the Z's and I'm just starting the restoration on this one. Thanks!

My restored, stock 71 240z has a perfectly good automatic transmission. My plan is to find a manual transmission soon, and hang on to it. Someday, if or when the auto trans goes, or I get sick of it, I will have the manual ready to go. And yes, I will also need ALL of the other bits and pieces to make the conversion. My issue is, should I go with a 5 speed or the original 4 speed. It seems putting a 5 speed in requires some modifications. I don't have a preference to either 4 or 5 speed, but I think putting in the 4 speed would be easier. I really don't like the idea of whatever changes or mods the 5 speed might require. I would just like to hear some opinions on this sub…
