    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.
