Earlier this month I purchased a 1972 240Z that hasn't been on the road in a while. I only drove it a little in the first week or so that I bought it as it wasn't registered yet, and the brakes were pretty bad. I definitely noticed a good amount of driveline noise, even at very low speed. Also, when turning the rear wheels by hand, you could hear and feel some notchy gear sounds coming from the diff. I'm now in the middle of a full suspension and brake rebuild with all the suspension components and the differential out of the car. The magnetic drain plug had some metal shavings, and it seems that the noise is coming from the spider gears Youtube video …

Ok so I've got a hole i guess on the drivers side of the block that a short metal pipe keeps coming out of .. there's oil now all over that side of the engine bay .The metal pipe has hose on it connecting it to the breather on top of the valve cover and it tees off to somewhere else also.. My questions are this .. what's the best way to keep that metal pipe from blowing out of the block and what is that thing called and what's it for? Sent from my iPhone using Classic Zcar Club mobile

Mine was missing, I got a correct one for it recently and decide it was time to install. well after about an hour of fussing with it last night I decided a different approach was in order. 1st remove the ECU and disconnect the fuel relay plugs. This gains a bit more clearance. next glue in the little plastic thing that mounts to the top of the dash, used some gasket cement. This keeps it from dropping out just at the wrong time. hook up the SHORT side of the spring to the clutch pedal (I presume this is correct, same as the brake IIRC). and maneuver the spring over the into the correct position. Depressing the clutch pedal makes this a bit easier (the …

I was going to post this in CO's "relocating the PCV valve" thread but it's fallen off the "Activity" page and I can't find it. Have y'all noticed that there is a wide variety of part numbers for PCV valves but they mostly look identical? Why is that? Why doesn't one size fit all? And will a PCV valve specified for a vertical application work the same if it's located horizontally? Is there a test for PCV valve function that is ore sophisticated than blowing air through it and shaking it to make sure it rattles? Why is there a spring only on one side of the internal valve? When does the valve close (it is a "valve" after all)? Just wondering if relocating …

I have two Nissan OHC valve covers from 240Z parts cars - one cover I personally removed from the engine of a 07/72 car. This cover matches the one on my car. The other cover was in the back of a 12/71 car and I presumed it came from that engine. Today I noticed two differences in the second cover: (1) the center section with Nissan OHC is raised the length of the cover to the oil filler neck and (2) the holes for the bolts to secure the plug wire brackets are smaller (the bolts and brackets were not on the cover). In checking the parts catalog, I find the same P/N for the valve cover across the L24/26/28 series - 13264-P0100. Any help on identifying where the second…

Howdy, Was able to get the motor running yesterday. I set everything TDC and realized that the dizzy shaft was 180* off. It makes sense why the motor was "backfiring" through the carb, the timing was off and perhaps a valve was still open when the little spark cam through. So I dropped the oil pump (3rd time) and got the dizzy shaft installed correctly. I noticed however on the restart of the motor after that initial "start" the starter seemed to struggle to rotate everything. (Bat tested 12.25v) I only ran it for a couple of seconds (1-2 tops), turned it off to inspect for leaks // oil. I noticed that the rocker chamber was super dry, no oil dry. Which is strange bec…
