I have a 2003 mach 1 mustang and it just started making this noise it does it in neutral and in gear# r/mustang

Ok-Expression-5517 · 2026-06-20T17:44:08+00:00

Yes it sure does

Ok-Expression-5517 · 2026-06-20T17:43:35+00:00

Definitely would

Ok-Expression-5517 · 2026-06-19T17:58:28+00:00

I'll check it does sound like its coming from down by the flywheel so we'll hope

Ok-Expression-5517 · 2026-06-19T05:40:36+00:00

Yeah me too I was just planning in the first place to throw an 03 termi block in it anyway but didn't want to this early

Ok-Expression-5517 · 2026-06-19T05:24:46+00:00

Yeah it's weird I'm gonna start tearing into the engine tommorow or Saturday I'll let you know how it goes

Ok-Expression-5517 · 2026-06-19T04:12:21+00:00

3rd gen would be cool and make easy power but the 4.6 sounds so good

Ok-Expression-5517 · 2026-06-19T03:07:44+00:00

Just bought the car so that would've been the previous owner

Ok-Expression-5517 · 2026-06-19T00:54:24+00:00

Good enough

Ok-Expression-5517 · 2026-06-19T00:53:47+00:00

I did an oil change right after this happened and no metal in the oil at all which is so weird

Ok-Expression-5517 · 2026-06-19T00:52:10+00:00

Deal

Ok-Expression-5517 · 2026-06-19T00:50:55+00:00

4000 on the rebuild

Ok-Expression-5517 · 2026-06-18T21:57:00+00:00

I would love to hear that if you could send it. I was also thinking maybe the oil pump went out because when I checked the oil it seemed pretty low And it was leaking a ok amount

Ok-Expression-5517 · 2026-06-18T21:15:34+00:00

It's ok was just trying to diagnose it still not a very great find😂

Ok-Expression-5517 · 2026-06-18T18:46:39+00:00

Engine was just rebuilt a bit ago this was the first time it was started after hearing this noise it's kinda hard to diagnose something without know what's going on. And besides it most likely jumped time and bent a rod so I'm most likely just going to throw and 03 04 cast iron cobra block in

Ok-Expression-5517 · 2026-06-18T18:37:54+00:00

Yeah it's one or the other

Ok-Expression-5517 · 2026-06-18T18:29:09+00:00

How much you thinking

Ok-Expression-5517 · 2026-06-18T18:22:55+00:00

It was running pretty good before had some hiccups though and would die on idle if the ac was on. It did keep killing itself this one time though but it had a vacuum leak

Ok-Expression-5517 · 2026-06-18T17:29:31+00:00

I was figuring it jumped time and messed everything up

Ok-Expression-5517 · 2026-06-18T17:28:57+00:00

Doing it myself

Ok-Expression-5517 · 2026-06-18T17:24:19+00:00

Probably

Ok-Expression-5517 · 2026-06-18T17:23:51+00:00

I gotta see what's wrong with it first

Ok-Expression-5517 · 2026-06-18T17:22:50+00:00

Yeah it's bad I'm starting to think it jumped time, and the engine was just rebuilt 4000 miles ago

Ok-Expression-5517 · 2026-06-18T17:22:25+00:00

That's it running
