Thanks for the info: also posted (with LV screenshots) to the Learning View discussion thread.

I didn't really push the stock tune, but the car felt kinda flat.

More penny dropping goodness: Due to the oil use issue, I'd been topping up with 5w30 Edge, which probably thinned the oil quite a bit and either brought on or exacerbated the AVCS issue.

what weight oil are you using now? i would use 10w min with the higher km your car has, i dunno why anyone would put 5w in an older subaru

It was on the shelf in 1L bottles, my bad!

Whats in it is whatever syn Docklands STi use, maybe Edge 5 or 10W40?

The answer is "lack of education" which is why I'm here

i dunno what subaru use and what brand it is, i use 15w50 motal lol it was recomended to me.

what are you going to use now?

should use the same top up oil as what was used in the car when serviced, i normally buy 2x 5l so i got some spare and when next service comes i only need one

Thanks for the advice , buddy

Some heavy hitters have recommended 10W60, and either myself or another member are likely to give that a go very soon.
I just bought Nulon 10W40 from Repco so they might let me swap it out for that.

In breaking news, I hope to have some input on this issue from the new service manager at the cars home garage, Docklands STi.

i like the 10 w 50 better ha ha

are you coming to kebab bbb?

BBB is a slightly used kebab.

Still logging the issue, looks like oscillations in RH VVT angle also happen on cruise at C 2300rpm, in comparison to LH VVT angle which is steady.
This is fascinating, since apart from the LH VVT ocsillation/vibration at C 1400rpm, there's no drivability issues...

I'll log warming up the car, induce the vibration, drive to the freeway, start cruise control and graph the results.

(I want to kebab but its the wife's B'Day!)

Even heavier hitters say this oscillation can occur upto 2500RPM at which point enough oil is fed to maintain sychronicity and negate the seal leak impact.

Perhaps a log of 2500 RPM + data will confirm.

Get some thicker oil in as well. You know the one...

Seals in the inlet cam, OCV solenoids or the blockage of the oil feed lines is the question I seek to answer with tonight's logging

edit:

proposed schedule of logs:
Parameters: revs, speed, L&R VVT angle, L&R OCV duty (optional)
warmup
induce 1400rpm vibration
cruise at 100kph @ 6th, 5th, 4th gears.

Any suggestions?

I'm going with Mick's diagnosis and am buying the part he's recommended. He told me he's taken this whole thing apart and identified exactly what's wrong and it aint the solenoids etc.

The guy genuinely knows his stuff from what I've seen so I'm going with his recommendation.

cause some people like keeping info with them as they make money and can fix issues other cant, happens all the time bit like the msr anti pop on gear changes
