    Brake leak help

    Alright everyone, thank you so much for the feed back. I'm finally back home and have some additional info... please bear with me. Two years ago I installed new OEM wheel cylinders (not cheap) from zcar depot. Last year I only drove the car twice because something bad happened inside my engine. I talked the wife into letting be buy a 2.7 stroker from Datsun spirit. Now I have an auto trans so I rarely set the e-brake. The first night of the engine install the car was on jack stands so I left the e-brake applied. The next morning I discovered a puddle of brake fluid under the rear drives tire. It appeared to be leaking from the hard/ soft line junction. So I tightened that up and cleaned everything up. Sadly the next night I discover it was still leaking. I cleaned everything up and decided to check once I got home. The strange thing is that it has not leaked since. I have about 450 miles on the engine and the rear wheel has no fluid leaking. I'm home this weekend so I plan to bleed it, but I'm still confused about what happened and why. Sorry if this ran a little long.Heres a picture of the new engine because picture make threads better. Cheers, Scot

    Brake leak help

    My drivers wheel cylinder leaks when I apply the e-brake. Does anyone have an idea why this might be happening? It doesn't seem to leak during normal driving. Thanks in advance for any ideas. Cheers, Scot

    Transmission help

    Agreed, for now I'm going to install the Datsun Spirit engine and keep the auto. That will give me time to get the extra cash for quality parts for the manual swap.

    I do have the pedal box, it's just the other $1000+ worth of stuff.

    Transmission help

    I have an automatic in my car at the moment and it has been fun for the past 20 years. However, there is nothing like rowing through the gears and I find myself wanting the manual experience. At the moment I have a Datsun Spirit Engine waiting for me to install. Really the big thing holding me back is the combined cost of the items I am missing for the conversion. I have the proper clutch pedal and brake pedal, but I need to source everything else. So here's a question for you folks: if it were you would you try to find a 5 speed? Again thank you for all the help. Cheers, Scot

    Alright I tried the pictures again. Thank you for the replies. Based on the information I've gotten it looks like I have a 4 speed series B. Is there anything else I should know? Cheers, Scot

    Transmission help

    Hello all, I purchased my auto 240z back in 1998 and the guy I bought it from gave me a manual transmission and some other bits to do the conversion. Well 20 years later I'm thinking its something I want to do. The problem is I have no idea what transmission I have. I browsed through the interwebs, but the seems to be an endless number of combinations. I don't even know if it's 4 or 5 speed (the box o bits came with knobs for both). I would greatly appreciate any insight you might have. Cheers, Scot P.S Sorry about the quality of the photos. The transmission is buried at my parents place.

    L24 compression question

    I did run my nail across the lobes and couldn't feel any type of groove or ridge. Tomorrow I'll try a little oil in the #4 cylinder to see if I get a different number. Any recommendation on oil weight?

    L24 compression question

    As requested here are some pictures of the cam. At this point I think I will button everything up and tackle repairs in the spring. My storage unit is not climate controlled and I don't want to leave any critical parts exposed to the elements.

    L24 compression question

    I'll post some pictures of the cam lobes later today, but I'm not sure they will show much. To my untrained eye everything looks pretty normal.

    L24 compression question

    I did not check the valve lash when I replaced the oiler because I thought I had found an easy solution (silly me). My plan is to pull the head, have the car towed over to storage (winters here in Montana are not Z car friendly), and spend the next couple of months rebuilding the head. Once the head is off I figure I'll be able to do a visual check of the pistons which might give me a little more information. I also plan to install a new timing chain and a more aggressive cam in the process. Thank you again for all the feedback. It's nice to have a community of knowledgeable people.

    L24 compression question

    Thank you both for getting back to me. The rear section of the Cam oiler came off and fell out when I removed the valve cover. This all started after a 300 mile interstate trip at a consistently high speed (80-90 mph). The other issue that I failed to mention before was smoke coming from the valve cover breather. I'm not sure if the issues are related. The engine stable at the same time as the sound in the head so I'm leaning towards a valve issue of some kind. The sound is pretty intermittent/ almost non existent at idle. If it was a tight rocker wouldn't it be more consistent? This is all a little frustrating because in the 19 years I've owned it it was running the best I can recall
  14. Hello all, My engine was running good, but developed an intermittent metallic sound in the head. I removed the valve cover and discover that the cam oiler had failed. I replaced that with high hopes all would be well only to discover the mystery sound remained. So I did a compression test and got the following numbers: #1=123 PSI #2=115 PSI #3=123 PSI #4=40 PSI #5=138 PSI #6= 145 PSI Now obviously there is a problem with my #4 cylinder. My question is why are the first 3 cylinders all consistently lower than the back 3? I have dual SU's and thought it may be that the front carburetor was partially restricted. However, I fully opened the dash pots and throttle and got the same results. For the record the engine was cold with all spark plugs removed and I did not put any oil in the cylinders. My car is and early 72 (11/71 build) and the engine and head are original. Thank you for any feed back. Cheers, Scot
