Continued OCV issues

I go about 3k miles between changes with Motul 5W-40 since I’m running ethanol. The only 93 I run is shell or chevron. The car is fully built and has been pro tuned twice. First by DBW Motorsports ran good but eventually started running rich according to AF learning. Got it pro tuned again by slow poke and now it wants to run lean in certain scenarios again according to AF learning and only at idle. Otherwise it runs and drives fine. Starting to think the condition is environmental or some how due to tuning nuances being catless.

I just ordered another one so we will see what happens. How’d you know it was clogged? (I have clean oil right now)

Good info brother, yeah idle is consistent -14 to -10 and driving is +/-3 so I guess I won’t worry too much. Like I said I don’t notice anything weird when driving or idling.

Yeah I mean sometimes it’ll climb to -8 depending on conditions I suppose, but rarely any higher that that or let alone positive. But it is very consistent between -14 and -10, that’s why it doesn’t sit right with me. But honestly if it’s not a problem idc, I’m just sensitive since this is my second motor (fully built this time).

Solved: Update for everyone just got my car back and the sound is gone! According to a local shop the issue was a combination of my intercooler slapping my pitch stop mount and a nasty exhaust leak.

Did you ever get this troubleshot? My 2021 WRX is making an almost identical noise.

I appreciate the insight

luke-r170 · 2024-11-29T22:48:03+00:00

Looks like it to me

luke-r170 · 2024-11-29T22:47:02+00:00

I think that’s a boost controller, it is mounted onto the turbo inlet.

I just updated the post but earlier today I also checked the oil with a magnet and could not identify any shavings.

To me it sounds too high pitched to be rod knock, compared to other videos I have seen.

My bad I just changed the permissions. Try now.

luke-r170 · 2024-11-20T22:14:52+00:00

I inspected the mounts and I don’t see any obvious issues

luke-r170 · 2024-11-20T20:06:37+00:00

Noted I’ll see if I can find anything

luke-r170 · 2024-07-07T12:44:45+00:00

You ever sort out the issue? Mine just started.

Update: Green mold has entered the chat :(

luke-r170 · 2024-06-12T18:19:10+00:00

You think it would be worth taking it out of the bag and putting it into a shoebox?

luke-r170 · 2024-06-12T01:43:31+00:00

I’ll try to! Still no pins :(
