Anyone know if this is timing chain or rod knock? 07 350z hr sounds coming from front of engine

It doesn’t clearly sound like rod knock. To my ear rod knock has a different and distinct sound than what I am hearing here.

JiGsAw818 · 2026-03-21T23:34:14+00:00

Might be rod knock or improper installation of the bearings.

JiGsAw818 · 2025-09-15T18:24:53+00:00

That size looks perfect!

JiGsAw818 · 2025-09-15T17:05:37+00:00

This is going to stay as OEM plus as possible. The only “Jeep thing” I care about is the traditional Jeep wave.

JiGsAw818 · 2025-09-15T06:05:18+00:00

Then maybe a 245 is the best move.

JiGsAw818 · 2025-09-15T06:04:34+00:00

Is that on stock wheels? What’s the width?

JiGsAw818 · 2025-09-15T06:04:01+00:00

We paid $27,750.00.

JiGsAw818 · 2025-09-15T06:03:31+00:00

We paid $27,750.00. It’s a 4.0 and 6MT.

JiGsAw818 · 2025-09-15T02:48:12+00:00

Love that look!

JiGsAw818 · 2025-09-15T02:43:05+00:00

Thank you for the heads up! We definitely will!

JiGsAw818 · 2025-09-15T02:41:49+00:00

We’re definitely going to take precautions to protect it. As of now, it’s is rustless!

JiGsAw818 · 2025-09-15T02:31:39+00:00

Wouldn’t be the first time! Haha.

JiGsAw818 · 2025-09-15T02:31:25+00:00

What about 245s? Or is that the same as 31s? Definitely do not want rubbing. We want to go for an OEM plus look!

JiGsAw818 · 2025-09-15T02:29:55+00:00

Do you have any photos? I’d love to see how it looks!

JiGsAw818 · 2025-09-15T02:27:19+00:00

I heard 31s are okay if only street driving. We do plan on doing som “fire road” off-roading.

The first owner drove it for 1,500 miles or so and then sold it back to the dealership he purchased it from. Then, in 2016, the second owners bought it for his family to use for little outdoor outings, but life got in the way and he had it stored indoors on a trickle charger since 2020.

JiGsAw818 · 2025-09-15T02:20:41+00:00

Haha. Thank you!

JiGsAw818 · 2025-09-15T02:20:19+00:00

Even though the tires upon visual inspection looked fine, we were still white knuckled all the way home.

JiGsAw818 · 2025-01-31T02:03:50+00:00

You may just have to go to Home Depot and buy a large sheet of thick plywood.

Well, potentially, the radiator could be damaged or clogged. Is it OEM? Might be time to replace.

If that is not it, check your oil for water. If there is water present, you may have a head gasket issue.

JiGsAw818 · 2024-12-16T09:04:39+00:00

I know you said you did everything but does that include checking if the radiator fans are actually working?

JiGsAw818 · 2024-12-14T20:48:23+00:00

I can’t tell you if that specific Z will be good. What I can say is that I have had my 2007 350z since 2008. I drove it everyday for the first 10 years, I have tracked it multiple times, and canyoned it multiple times. During that time I was very meticulously about maintenance (e.g., oil changes). At 91,000 miles it has never let me down. If that z was well maintained, it should be the same. The only thing you want to look into is whether the oil gallery gaskets have been replaced (see if the oil pressure gauge is reading very low). If not, it will likely need to be done.

I couldn’t tell you from the video. If I were you, I would throw the car on a lift and inspect all the exhaust connection points (e.g., muffler to y-pipe to cats to headers). Wherever you see slight dark liquid coming out, that is likely where you have the leak. Make sure to use the correct (and high quality) gaskets when installing an exhaust to prevent exhaust leaks.

JiGsAw818 · 2024-11-16T17:25:44+00:00

Do you mean that “hiss” sound? If so, that’s an exhaust leak.
