Take a look at this picture of the piston top from my L24. It's got 200K miles and is about to be replaced. The compression was low on all cylinders and rose with the addition of oil. Are those shiny clean areas around the edge of the piston from blowby due to worn rings? I've got an L28 that is going in, and this block will likely not be used again by me, so I'm just asking as part of my ongoing Z education.

Ok heres the problem: When i touch the exhaust tip the whole thing started moving, and it wobbled for a while, looking under the car shows that it is attached to nothing, it goes straight from the header to the end. I cant see any places where the thing might have mounted. So can someone give me some advisory on what to do? Thanks alot.

I rebuilt sometimes ago my fan clutch as per tech tip on this site with silicone oil. The O ring was good and I put gasket sealer before reassembling both halves. I noticed today that I have oily spots on the underhood as before the repair. The fan blades also have black oily deposits and the clutch too. It seems that I have no choice but to buy a new fan clutch. Any comments or suggestions

On the '74 I have triple mikunis... Those of you that are running this or any triple setup, what are you running for fuel pressure? I assume that since these are not a draft style carb, the pressure is important as far as performance goes, not just keeping the bowls full.... At a sustained rev (3k RPM) my pressure is dropping to 2 LBS or so and at an idle it's at 5 LBS. I think that the motor is low on pressure fuel wise which is contributing to performance issues as far as demand goes, I have a great pull in the first few seconds then the engine seems to "drop off" a bit. Any suggestions as far as fuel set up goes? I am currently running an electric pump that has a ra…

I have a '73 240Z with the stock ignition system that I want to upgrade to electronic ignition. I've seen this discussion before, but still have a few questions that I'm hoping someone in the group can help answer. 1. What are the merits of going to a 280z distributor vs. adding a new pickup to my existing distributor? 2. Does anyone have experience with the MSD 6A and Crane XR3000 units? The MSD seems more popular, but the Crane comes with a kit to replace the points on my existing distributor, and is also cheaper. 3. How important is it to replace/upgrade the coil? 4. Should I expect any issues with my stock plug wires if I do all these upgrades? The rest of my engi…

Hey all. My '83 ZX's (I know, I know ) 5 speed tranny is beginning to show its age. The synchros are getting a little balky especially when its cold outside. As the tranny fluid has never been changed in the last 20 years (to the best of my knowledge) I'm thinking new fluid might be in order. Any thoughts on whether I should just use straight gear oil (40 weight if I remember correctly) or has anyone used some new wonder fluid that will help "renew" those tired synchros without damaging the tranny. Thanks, Peter

I am ready to order JE forged pistons for my F54 block that will be used for a turbo project. I planned to only bore it .040 over but is there any good reason not to bore it more? I have read posts about of weak stroker motors that have been bored to large and come apart too easy and don't want the same problem. I am using a P90 head with a schneider cam that has it best power between 3000 and 6500 RPM. Also I want to stay around 8 to 1 compression ratio and will be using a good engine management system. Can anyone provide me with an experienced opinion about how much the F54 can be safely bored? Thanks for your help..........mayolives.

Lately I've been running my 73 240 with roundtops as lean as I can to deal with some idle issues. One side effect is that applying the throttly gently, such as going around a corner slowly in 2nd gear, results in a jerky response from the engine. It's just not possible to accelerate gently and smoothly at the same time. So I was playing around with things and removed and plugged my vacuum advance. I also advanced my timing from about 8 degrees to 15 at idle. Interestingly, the jerkiness at part throttle is almost completely gone. And I find it pulls to 6k rpm just a little stronger as well (due to the extra advance, maybe?). So my question to the group is what am I g…
