    Very shiny and clean! What did you use/process to clean them?

    Yes pattern parts can be somewhat different to the genuine parts. You get what you pay for in the end unfortunately.

    I used, in the following order, Loctite7200 and a scraper, dishwasher cycle and WD40 and a brush.
    WD40 and the brush was the most effective method to remove deposits from unreachable corners on the pan, as it's a very good solvent.

    I used just what I had at home, and I don't recommend the dishwasher because is very salty and will attack the aluminium

    Anyway, compression values:

    Attachment 32695
    Attachment 32696

    According to VIDA, compression values should be between 11-13bar (160-185psi?), these ain't but are definitely a good improvement over my older engine. What values are you used to see?
    The values in VIDA are for a 'WET' test. Clearly you did it 'DRY', whether or the not the engine was warm, makes no difference.

    Try the compression test again but this time, using a long reach oil can with a pressure trigger, squirt a small amount of engine oil into the cylinder as far into the spark plug void as you can. This will make a wet seal around the compression rings and then do a compression test.
    You see the values rise considerably on the gauge and will likely be withing Volvo spec, unless you've got a serious problem and a broken ring.

    wow ok, that's important information I didn't know, thank you. I might repeat the test, together with an oil pressure test once I've put everything together.

    It doesn't look like new but I think it has improved a lot.

    but, how can you explain that this compression tool returned VIDA values in a friend's T5? 12-12-10-12-12 Because it ate a spark plug.
