    84 720 Failed California Smog :-(

    The NOX being near upper level could indicate it's running lean, possible vacuum leak somewheres would also trip the HC levels to be high as it isn't burning the fuel it's given. I live in So Cal, smog laws can be a b*tch

    510 strut top fail......oh no

    Thanks....yeah I had looked all over for stock sized 510 struts to drop into the strut tubes without success (for some reason the older 510 length strut inserts are not easily found)....... however the ZX struts are avail everywhere and by reading some of the more in depth posts on here regarding using them in the 510 I was able to make the upgrade easily. I replaced the boot and bumper while it was apart and along with the new bearings and strut top insulators mentioned before the wagon is all set 😉

    510 strut top fail......oh no

    Correct..... I followed the advise given by many Ratsun folk and used ZX inserts along with approx 2in of spacer in the stock tubes to make up the difference. I wanted to stay near stock ride heights so no need to swap out the strut tubes. Works great

    510 strut top fail......oh no

    So I finally had time to dig into this problem further and as I suspected the rubber insulator had worked itself into powder allowing the metal center cup to push up and out. I had looked locally at different solutions (since I didnt want to use old parts) but finally settled on these from Zcar https://zcardepot.com/all-products/suspension/front-suspension/front-upper-strut-mount-insulator-280zx-510 . The pics tell the story of course. Now with all the bushings, struts and now these insulators replaced the wagon feels like a new car (well better at least....haha). I hadn't realized the car had been leaning towards the driver side caused by that strut bearing being sucked up into that failing rubber insulator.......all good now 🙂 -- Ray

    GOONS check in

    Sounds like you have a weak/dead cylinder..... do a compression check and proceed from there, my guess is you have low one. Glad you got drive it!

    510 strut top fail......oh no

    The only theory that makes any sense is that the bearing may have been binding bad enough to "twist fatigue" the rubber insulator over time. This wagon is a daily so it is never still for long in our house.....lol.

    510 strut top fail......oh no

    Shocked me to see it lemme tell ya...lol. Yeah the rubber center just gave up and looks like the pass side won't be far behind as the rubber has a huge crack around the majority of the center. Your pic Mike shows the bearing mount (top hat) for both cars....the bearing saddle and the bolt circle look pretty similar and I have hope the ZX mount will just drop onto the 510 strut. In hind sight the upper bearing on both sides has not been turning smoothly (when it was in my hand 2 weeks ago and I regreased it felt smooth but under the weight of the car it was notchy) and I had wanted to replace the upper bearings and mounts but was not having any luck finding new replacements. I'll pull it apart this week and try and match up something at the parts house :)

    510 strut top fail......oh no

    Yeah the rubber insulator just got weak enough to let everything below it bust up right through........ it is weird. From what I can gather (searching these forums and interwebs ;) ) the later 280ZX might be a drop in for replacement upper strut mount? It does have ZX strut inserts but stock struts otherwise (no low). -- Ray

    510 strut top fail......oh no

    Not sure what you mean Mike, it's assembled as stock.....just now the rubber insulator has given up and allowed the strut, bearing and associated bits to break through :( Never seen one do this??

    510 strut top fail......oh no

    So while driving I hear a loud thud and then notice my hood is sitting a bit tweaked.... popped it open and bam lookee what I see....ugh. Just got done installing new strut cartridges and bushings all around, now this happens :( The struts are stock besides 280z inserts.....what are my replacement choices? I did the Ratsun search but nothing definite showed up. Just read that 240sx top mounts are a match to the 510's bolt pattern, will the 510/ Z car strut slip into it? That would be an easy fix if so! Thanks all :)

    Need pics of 620 tension rod installed

    What I need to complete my L20B

    THIS /\ /\ /\ !! Both my wagon's L-16 and my 620's L20B came from him...........one had a bad head (cracked internally) and one had been built incorrectly and started using oil. I won't be a repeat buyer from here on, he's had other probs as well on here.

    looking for pics of 13s on a 510

    Just your standard direct from the dealer 13x6 slots, stock suspension :)

    78 620, L20B foreign matter in combustion chamber.

    I was doing the same mod to my '74 umpteen years back, pulled the EGR lump off there and was gonna make up a nice new PVC mount, block off plate etc..........noticed then that the truck throttle cable mounts to that EGR plate so no go. I ended up welding those two passages shut in the manifold and lopping off the entire EGR portion of that intake (hangs off the front of the intake...ugly) You could also use a 521 cable mount which bolts on two of the carb mounts. --Ray
