I'm posting a new thread hoping to get some feed back (Thinking about freshening up my suspension). If you have been there done this or know without a doubt the facts, please respond. My ASE mechanic friend and I just spent 6 hours trying to put the rear end/suspension back in to my car, a 1975. I am no further now then I was when I started, just frustrated and pissed. It should not have taken 2 hours tops. Long story, short... I removed the sleeves out of the mustache bar in preperation for my Prothane kit and now realize I should'nt have. I waited 2 weeks for new Oem bushings that are probably on indefinate back order and decided to purchase a used mustache bar in…

HIguys, I thought I'd mention something you might like to hear: I just received an endoscope via eBay, that works with my Android tablet. I think I'll "look into" my engine, *if* it gets warm, or whenever Spring comes along. It might be interesting to see what the pistontops look like. It's supposedly waterproof, but I don't think I'll be looking into the rocker box. It was about $10

Guys I need help here figuring this out. I have been fighting an oil leak in the rear main seal area which I have posted here. I have done everything including a speed-sleeve on the crank where the rear seal rides. I have always thought my oil pressure was too high on this engine, but discounted it because of the stock gauge. Today I installed a new oil pump(standard pressure and volume) and installed a mechanical gauge inside the car. No change. The oil pressure reaches 70psi before I get to 3000rpm. At cruise it will stay right at 70psi-cold or warm it doesn't matter. If I understand the pressure relief valve and how it works, 70 is the magic number as far as max pres…

How can you get the throttle torsion rods off the intake on a 280Z? I got a tin-zinc plating setup so I can plate exposed parts like that. thxZ

One suggestion by "experts" to help protect your car from being stolen is to disconnect the HT wire from the ignition coil, (or remove the rotor, mix up the spark order, etc.) but that seems like an obvious thing for a thief to look for, except for that last one. But what if you had some kind a "dummy wire?" Just disconnecting the HT wire means you will have arcing from the coil, which will harm the coil, and disconnecting only one spark plug will still allow the engine to run, albeit slightly poorly (BTDT ) so if you had a safe way to allow the HT charge to go to ground, the engine will turn over and everything will "look" like it should, but still not start. …

Would it be okay to mix Redline Gear oil 75/90 with MT-90 75/90 for my differential? I have half quarts of each left from previous changes and I want to change out the oil in a R180. Thanks for any replies, I haven't been able to find a definate answer searching the internet.

Im having an issue with cylinder #4 as whenever i race the car and make a couple of stops and leaving the car at idle for 5 mins in the garaje, spark plug 4 (NGK BP5ES) comes out fouled and sooty. I have both front and rear roundtop su carbs at 3 turns clockwise. All of the other plugs are burning correctly. Could my car be running only on 5 cylinders? mechanic says i need a valve adjustment but cold and not hot. Do you concur???? the car does not have the original cam but a Schneider 274F to compensate as my engine was bore to 2.6 L and not 2400 cc as original. http://schneidercams.com/274FL6.aspx Is a valve adjustment at cold required better than Hot?

I ordered brass plugs from Amazon and also tried the ones sold by Home Depot but none of them fit. The opposite hole has some sort of rubber plug. Any suggestions on sealing this hole? Howard

I made this table back when we were thinking about using a diesel crank in my 280z block and thought I would throw it up on the forum in case anyone wanted the information. It doesn't tell you anything that you can't find through reading all of the threads on which rods are best for which combinations of parts, but it was helpful in understanding what the overall options are when it comes to finding rods from different Nissan engines to make funky changes. The color coding was to help me figure out what clustered together. Given that you can get whatever piston dimensions you want these days, you can do a lot with this. We went with the non-standard-but-common L28 block +…

Some of you may remember that I bought a hot Rebello motor for my early 260z and when I first started it there was a clunking sound. Luckily that problem ended up being a clutch slave cylinder bolt that was too long and it was resolved pretty easily. Since then I put about 200 miles on the new motor and its been reliable. Yesterday I went to my garage to start the car for work and after running for about a minute there was a horrific clunking sound so I shut it down immediately and took the truck to work. Its been cold (for the middle of California) in the low 30's (about 0 Celsius) but in the garage I estimate the temp to be in the mid 40's. After work I took out al…
