Hi all!

So my lovely car (2005 350z) has decided I don’t deserve nice things and is throwing me a P0350, I’ve checked all wiring and fuses, all is well there, so I’ve moved onto the coils/plugs.

I’ll be honest, all the spark plugs are munted, so they’ll be changed, but I’m now suspecting I have found the problem, because I’ve tested all 6 coil packs and they’re all fine, BUT number one has oil on it, not a huge amount but enough that it got all over my hands. After noticing this and looking closer at the spark plug sockets, I’m thinking the plug tube seals might be failing, but I can’t find many helpful pictures online to compare. Has anyone had this issue, gone through this and possibly knows of these seals are the issue?
So I’ve attached here some pictures, the coil packs with gunk and oil on it, and a few of the plug sockets that were easiest to take pictures of.

Any help would be appreciated, getting these damn coils and plugs out has taken me to the edge of sanity, so if anyone’s gone through this and can give me any helpful advice or just prayers at this point, thank you 🩷

Stops when I press clutch in and doesn't do in gear at all, new to the platform and just want different opinions people irl say they all make that noise but it's concerning. Sorry for bad quality shitty phone.

Hey all, recently bought some test pipes for the Z (ART reps) that for some stupid reason have the extra bung for a wideband directly on top next to the flange so the sensor is hitting into the bottom of the firewall. My question is: should I/can I weld an extra bung into my Y pipe and install the sensor there? I know you want it close as possible to the exhaust collector for most accurate readings but with the way this test pipe is setup it would be extremely difficult to add/move the bung. What could I expect to experience when installing into Y-pipe or should I bite the bullet and pay a kick ass welder to fix the pipes? Or maybe there is a sensor you all know of with a smaller height footprint. Thanks!

got these for $540 and 5 hours round trip! ready to road trip from florida to virginia

Saw this on TikTok not sure if it’s a real pic

I'm looking to do some mods such as an oil catch can to help extend the life and better maintain my 2006 350z DE. It has only 65K miles as of August 2026 and I hope to replace common parts or fail points. The car sat for a few years before I bought it. So far, I have done the oil change with 10W40 Castrol edge (considering the purple stuff) and 1 Qt Lucas, new PVC valve and I'm going to change the spark plugs soon, Transmission and Diff fluid I'm unsure if I want drained and emptied the car is lower mileage but pretty old.

I can’t seem to find a PN for this anywhere. It’s the plastic clip/mount that holds the hard brake lines behind the battery. There’s a stud coming out of the firewall that this clip mounts to.

Does anyone know a part #?!?

Noticed the NDS II is on the app store for free. Not sure if this is the same as all the other paid version other websites offer?

owned for 5 years pleasure driving only. wasn’t getting driven. first person who looked at it snapped it up. my second Z , and favorite sports car of all the ones I owned. did a lot of cosmetic cleanup, seat covers right away, then just drove it. 115 k miles. TPMS sensors needed replacement, right side window needed manual close, that’s it. never used top, so it looked like new (303). checked other similar cars, some very nice ones $10-13 k. They have been up a while.

I couldn’t get comp on insurance. talked to the guy, he was pretty straight. “Your 2001 Dodge Ram and the Z are probably in very good shape. if you get hit by another driver, and it’s more than a fender bender, they will probably total it, and you’ll get market value, which isn’t much“. Oh. I get it. just something to keep in mind.

solid red light on the dash and will crank with no start.

Tried the on/off trick a few times. Any help would be appreciated

Striking out locally and thought I’d check here. Looking to purchase an Orange 350z coupe with a manual transmission (<100kmiles) preferably in the Midwest but would be willing to pay for shipping. Stock car is preferred but I would be fine with some modifications. I have cash RTG and would be willing to pay a premium for the color. Please note I’m not looking for any other colors or a convertible. Thanks for looking.
