A while back, I heard that the original distributer cap was grey. Going off of that and a poor quality picture on BAT, I was able to find a grey YEC branded cap, but didn't know if it was close to the correct color. Today, I found a picture of an original Hitachi distributor cap: Putting that here for reference for others.

Does anyone know of a shop rebuilding 5 speeds in the PNW? Close to Portland is preferred, but am willing to drive if there's someone who has a ton of specific experience with Datsun stuff. Thanks in advance!

I have been rebuilding my differential for the last couple of evenings. It is a "K" R180 from the front of a Nissan 4X4 truck. From running it in my 240z, I know it was in good condition before disassembly. And, when I took it apart, I checked backlash and it was within spec. So, I don't believe it ever had been apart before. I purchased a Quaife LSD for it. I also purchased all new bearings and seals. For the differential case and the drive pinion shaft, I was very careful to install races and the tapered bearings, fully seating them in their correct positions. I also was sure to use the spacers and shims that were removed back in their origin…

I don't want to hijack the other thread on a R180 LSD installation. I have two photos attached on an LSD being installed. One from the internet from a Subaru that shows it just goes in nose first, is turned with two fingers, and slides into place. The other one is of my KAAZ LSD going in nose first and not moving beyond that position. The Subaru was replacing an LSD with another LSD while mine has never had an LSD. The ring gear almost clear the side of the housing. Are there any tips on what I need to do other than keep at it?

Hi yall! First post here. I've been trying not to ask too many questions and research on my own before begging for help, but I can't seem to find this answer. Other posts where close but not quite. I'm rebuilding a '72 240Z (Feb). The car wasn't running when I bought it, so I'm nervous to rely on previous owner's status quo. The smog system was removed and the two hose spots I highlighted in red are were empty when I got the car. Parts manual calls it a "hose pipe connector." If I keep it open like previous owner had it, does that have long term effects on the engine? Like can gunk find its way inside? Do I install a hose just to cover them? Or block off totall…

Hey gang, On a '78 I'm told the cam is 'internally oiled' (instead of using the oil spray bar). What does that mean and are there holes somewhere on the cam that spray oil while rotating or something? I looked but didn't see any... -chase

I don't see any other threads like this on here, so I hope this is not inappropriate. Honestly I don't care for the HybridZ website, so I don't feel inclined to post there much. This is my long term plan for the 280Z. A neighbor who is also an old car buff stopped by about a month ago, he told me his wife's uncle had an '06 350Z that wouldn't pass inspection in RI ( I had told him earlier that I was considering a drivetrain conversion at some point in the future). The car is mechanically sound, so having the entire vehicle for the cost of an used engine & CD009 trans of unknown pedigree made sense to me. My personal experience with buying JDM drivetrains has not …

I finally got a lead on a 5 speed, which has been sitting on the shelf since the mid 90's at a Sacramento manual trans business . Went to look at it, appeared to have a close ratio tail housing. Did a quick check of the 1st and 5th gear ratios by marking shafts and turning, not too accurate. Estimated 5th was .773, and first was 3.6, which I thought odd. They recently replaced the seals since it was sitting for so long, and came with 1 year warranty. They unfortunately painted it gray, ugggh. Anyway, decided to buy it. It looks like like a typical close ratio tail shaft housing, no dust shield, bottom speedo bolt, one rear tab, reverse lockout plate. Its does …

Hey Guys, I have been trying to tackle an elusive problem on my Z that has been happening since late last Spring. The issue is that During a cold start, the engine taps extremely loudly for the first few seconds, then goes away and it sounds normal. Then once it is warm it seems to just slightly tap, but not nearly as loud. If I let it sit for a little and then start it hot it will tap loud again during startup. However, sometimes about every 10 starts (different days) during hot or cold start I won't hear any noise. I tracked the tapping sound to the head toward the front of the valve cover. I am thinking 2 or 3 valves back from the front. However, I have…

I've got my 4 speed out to fix an annoying drip, replacing both front and rear seals. Spent an hour or so cleaning up the input shaft housing, old Permatex on gasket area, and sealant on threads and washers. Threads go into case, so FSM calls for sealant on bolts, but not much else for help. Ready to put back together, and obviously don't want it to leak. What is the best practice folks have found to get this leakproof? Thanks!

Got my intake manifold back from the machine shop, and the EGR gallery has corroded so thin you can poke through it with a screwdriver. I have a sinking feeling this manifold is toast, but with a flashlight in it I can't tell whether the ports between the EGR gallery and the intake are open. Anyone have any insights?

I'm trying to determine the gear ratio on my R180. There is a number on the ring gear of ?? x 394 Does this mean 3.94:1 ? Should I just see how many turns of the differential input is required to make a full revolution of the ring gear? Can anyone assist in decoding this? Jeff
