When I took my distributor out, the housing was packed with a thick grease. It was grey/silver in color. I haven't found any reference to putting grease in the housing during a rebuild in any of my manuals. Anybody know what this is and is it recommended? Bob

Leaking Head Gasket

So I spent most of last night fixing an oil leak caused by a bad gasket on the oil pump. Once i finished that I set my timing and took the car out for a quick spin to check the seal. Once I got back home I looked under the car to see if it had worked and I noticed a stream on coolant running from the back of the block. iIfollowed it up to the top of the block and found that there was a leak coming from the head gasket and spraying onto to transmission. Its a small leak. It's not blowing any smoke so I think its just leaking to the outside. Does this mean its time to replace the gasket? This isnt work I would do myself, so if yes how much does it usually cost to have this …

I am hoping the wise and esteemed masters can help me...we finally got the carbs sorted out and the car is now running fine (even better when I remember to put gas in it)...anyway...I have been having a hard time shifting into Reverse and other gears...we have diagnosed the problem to be the slave cylinder and I have a call into NAPA to see how much it will cost to get a new slave and master... The reason I need help is I would like to go ahead and change the clutch assembly at the same time. My car is a '71 240z (Build date of 12/70) but the previous owner installed 5 speed out of an 83 280zx. My question is which clutch do I buy? Which pressure plate? Which throw-ou…

Timing Indicator Plate Location

I have noticed on every z motor I have pics of the timing indicator tab is located on the passenger side of the car. Mine is on the drivers side. Is this a common place for just the 73? Searched around but can't find an answer. I have a new one for the left side and I think my original was "lost" at the platers, still hunting for it. The notch on the damper is also on the drivers side. What gives?

5 speed install

I'm getting ready to put the 79 280ZX 5-speed into my 73. I noticed that the 5 speed only has one electrical connection, toward the front of the tranny near the shift fork boot. I assume its for the reverse lights. The 4 speed had 2 elec. connections (back-up lights and neutral switch I guess). If I don't connect the neutral switch, is that annoying seatbelt buzzer going to be going off all the time?

Inner Shift Boot?

I have installed an 83 5 speed into my 70 Z. I have read in previous threads about an "inner shift boot" that protects the top of the tranny from dirt, etc. Mine does not have this, is it supposed to? I never saw one on my original 4 speed, so not familiar with it. This is not the inner rubber boot that goes under the shift boot over the console, but one underneath it. If there is one, what is the part number? Would like to order one! Thanks!

Here's a pic of my almost complete engine bay. This weekend I cleaned and painted my fuel rail, installed ignition & alternator wiring, etc. Still need to replace the positive battery cable, install hose clamps and clean-up the emmision components. Starting in mid-January I plan to figure out how I'll mount the compressor, condensor & routing for the AC lines.
