I've done the soak twice now, once for 8 hours, a 2nd time for 24 hours. I've got a borescope so I will have a go.
there is no PCV anymore - I've configured a draft tube arrangement - filter on the exhaust side, 'pcv valve' is a straight barb fitting to the catch can and the catch can vents to a draft tube, there's a wee bit of oil at the bottom of the catch tank - and it's working.
I checked the cold idle blowby and it doesn't seem excessive, but I need to compare with my turbo car which has PCV, really.
Next step is to get the cylinders leakdown tested.

Goodness.
Checking leakdown and bores would have provided more info to troubleshoot initially.
Good luck!

The compression and performance seem to be good but I want some numbers 'so I know'. I've got the ITV/MOT test tomorrow. Once that's over I'll head over to a shop that might do the test.

Passed the test, 2nd time. After some frustration with the fact that it has a 'new' license plate but it's a 1992 car. Cat tests are only required on 1995 and later here.
On the smoke front. I've seen nothing for the last week. More driving required.

So this is a very late follow-up but I thought it worth mentioning.. I moved to a thicker oil - 10w50 and that solved most of the smoking issue but I could still, let's say, 'provoke it' ;)
After having seen some higher oil temperatures (on the motorway) now I had some data collection in place for that (bosch combo sensors wired up to the link g4x) - a few days ago I switched to a higher flowing thermostat (Made in USA, 160f 72c) - and that dropped my coolant and oil temps both by around 20c - coming from max 126c to max 106c oil and from 100c coolant to 80c coolant.
Result - 40kpa more oil pressure minimum, sometimes more, and I can't get it to dump smoke on over-run at high revs - thinking being the higher temps were causing the rings to lose tension.
RS Delta is now asking me to do a video.. so, one day.. one day! I feel a bit more tempted now.
