After 250 000 miles, I finally got around to renewing the valvetrain components of my Volvo 240. Springs and hushers being the main items to replace. I also adjusted the fuel distributor system pressure, control pressure, flow plate and CO mixture.

Next up, tuning fual distributor system pressure<\/h2>\n\n\n\n

System pressure was only 4.6 (not shown in photo), so I carefully got the pressure regulator out and added shims to it. Quite a lot of shims was needed, I think the spring had gone weak.<\/p>\n\n\n\n

After that, I centered the air flow sensor plate and checked the rest height. To be able to tighten the flow plate nut without it moving, fold over a piece of A4 paper and slot it down all round the plate. This has the right thickness to keep the plate centered.<\/figcaption><\/figure>\n\n\n\n

Next, CO tuning. Incidentally, if you can’t find a photo of this either, this is what the bung down the CO adjuster screw tube looks like:<\/figcaption><\/figure>\n\n\n\n

I screwed a little screw down the tube and pulled it out.<\/figcaption><\/figure>\n\n\n\n

That’s it. Next, replacing the power steering pump…<\/p>\n","protected":false},"excerpt":{"rendered":"
