Working on my ride, this hole (first picture) started leaking white milky fluid. 1. What is this hole for? 2. The White milky fluid was oily, so I assume I would have to change the head gasket. Is there any relation to the milky fluid and the missing pipe that goes into the hole in the first picture? The previous person mickey-moused the car. I am learning so please dont set a noob on fire, I would like assistance. Daniel

i have a 71 240z. just bought it about a month ago ran into some trouble driving it around last week. my biggest problem is the rear. the left rear wheel shudders and wobbles (i checked the lugs). also when i jacked the car up i rocked both rear wheels and theres a good amount of play. i assumed it was a loose/worn bearing so im replacing it. . also replacing half shafts and uj as well. the right wheel does not sit center to the car. seems like it is sitting more towards the front of the fender. also when test driven it has a grinding noise coming from the rear. assumed its the differential. i just want to know what else to check for when i inspect it again and anymore su…

Since it is possible, and even acceptable, that Engine Serial Number can be different from the Chassis serial number,was there any re-ordering of the engine numbers? For example, my chassis number is 434056, but the Engine Number is 280438,and I believe that the engine is the original one, so I get the idea that they re-started the engine numbering with the new L28 design, because it is significantly different from the earlier carburetted engines. It's hard to justify that a difference of about 154,000 between the Chassis and Engine numbers, even with the knowledge that Datsun's record-keeping was not to good.

Just got the car on the road recently with a new to me close ratio 5 spd tranny. In all ways I would say it works very well except in 3rd and 4th gear on hard acceleration there is a high pitched rattling from the trans that I can hear and feel in the car and can hear coming from under the car through the windows. Does this mean a rebuild is needed? I'm running Redline MTL 75/90 trans fluid. Thanks, Chris

Hello, I was under the impression that n-42 heads were only used on 75-76 280z's with EFI. I came across one which was not drilled for injectors and expressly for use with carburators. Which vehicles were these made for?

Does anyone remember reassembling a 4 or 5 spd transmission from a Z from the 4 spd era to the 5 spd 280ZX transmission era and remember the ease of putting in the return to center bolt? I am wondering if I can pull that bolt out and put it back in without taking the transmission out of the car. My return to center is weak so I tap reverse sometimes when pulling out of 5th. This also makes it hard to find 3rd sometimes. I understand from the two rear ears on my 5 spd that it is the older 5 spd transmission if that helps. I have read of someone else cleaning and greasing the spring and whatever it pushes on (I don't remember it being a ball bearing) and that fixed the…

I became a Z addict in 2003 and was very active in learning about the Z I just bought. I enjoyed writing tech tips as I learned so as to help others but some friends at work betrayed me in 2005 and I had many challenges from 2006 until last summer. I did manage to collect some data and tech tips that were in limbo and post to this site in articles as well as put some new ones up. I also had a fun project to restore a series one that was a nice break from the tough times. Here is a tech tip that was lost on the net:77 280z Clutch master and slave

I'm starting a new thread, since the other one discussing cooling kind of went off on a science tangent.... I drove home tonight (about 10 minutes, 7 miles), and the engine temp gauge indicated that the coolant was up to temp. Upper radiator hose hard and hot. Open the hood with the engine still running and look at the fan. Spinning, but kind of seemed to be slower than it should be. Turned off the engine and immediately tried to turn the fan by hand. I could spin it with one finger. Sound bad? The factory manual is useless for this - gives you the theory of operation and then just says to check for oil leaks and bent bimetal, and replace as a unit. Is this thing …

Transmission and Rear End Gear Ratios So this shows that there are three different 5-Speeds from the 1979 to 1985 Datsun 720 pickup. Says that it bolts up to the L6 motors too. What I like is that one of the transmissions has the same gearing as the two-piece 4-Speed, but with a 5th gear. Any data on this transmission? What year and models it came on? Is it the same length of the two-piece 4-Speed? Build with it done? I want to keep an eye out for this transmission.
