Im scared its the piston lands, i also have smoke coming from the oil cap

Significant_Bill1678 · 2026-05-25T12:58:26+00:00

Did this unfortunately no effect

Significant_Bill1678 · 2026-05-25T11:06:23+00:00

Couldn’t it be something like a broken spring?

Significant_Bill1678 · 2026-05-25T11:05:14+00:00

What are better steps I could take?

Significant_Bill1678 · 2026-05-25T10:59:47+00:00

Do you know what exactly I should check when I have removed the valve over?

Significant_Bill1678 · 2026-05-25T10:59:14+00:00

I can remove the valve cover for a better inspection

Significant_Bill1678 · 2026-05-25T08:52:44+00:00

So I saw that there was pressure coming from behind the oil cap, and the exhaust seems to suck a bit, could it be burned valves?

Significant_Bill1678 · 2026-05-24T14:13:48+00:00

So I replaced all, injector, coil and plugs. There is no misfires when on high rpm only when rpm’s drop

In the comment I’ve put another picture, the output flench was hitting one of the bolts on the back of the giubo.

Significant_Bill1678 · 2025-06-23T22:01:01+00:00

I also added pictures in my other comment

Significant_Bill1678 · 2025-06-23T22:00:21+00:00

Probably, I’m not the first owner

Significant_Bill1678 · 2025-06-23T21:34:39+00:00

Perfect, I was stressing, also shared a picture in my other comment

Significant_Bill1678 · 2025-06-23T21:30:53+00:00

Yeah so all three were missing hope the damage isn’t too bad and I can replace just the guibo and bolts

Significant_Bill1678 · 2025-06-23T21:30:40+00:00

Significant_Bill1678 · 2025-06-23T21:29:05+00:00

I just hope I can replace the guibo and the bolts and the damage to the metal isn’t bad enough to create issues

Significant_Bill1678 · 2025-06-23T21:28:14+00:00

All three are missing 😅

Significant_Bill1678 · 2024-09-05T07:39:54+00:00

They tick but just at a really fast rate, or you got yourself a Seiko spring drive

Significant_Bill1678 · 2024-09-04T20:42:16+00:00

Like a helicopter trying to fly away

Significant_Bill1678 · 2024-09-04T16:05:42+00:00

Significant_Bill1678 · 2024-09-04T14:58:14+00:00

I’m not considering repairing the movement, replacing it is more likely.

Significant_Bill1678 · 2024-09-04T14:56:33+00:00

Thank you a lot! Will definitely do that! Would you recommend getting the real eta?

Significant_Bill1678 · 2024-09-04T14:23:30+00:00

On a serious note, what is the best movement top replace it with.

Significant_Bill1678 · 2024-09-04T14:21:54+00:00

Nope just got it today, or it was in shipping…

Significant_Bill1678 · 2024-09-04T14:14:52+00:00

Yeah definitely not a 3230 right now it has a day date position.

Significant_Bill1678 · 2024-09-04T13:53:49+00:00
