1982 300D

Hi, everyone. I had planned to adjust my valves over the holiday weekend, but I'm concerned that the working temperatures (in the 40s) could affect the adjustments. Am I okay to adjust them in this cooler weather, or do I have to wait until spring

I ask because I seem to remember someone saying that colder weather can affect the valve adjustments. I'm just not sure how cold is cold enough to be a factor.

Thanks,

Pete.

Its always recommended to adjust them cold. I think it would be just fine to adjust them in those temps. Whats not good is to adjust them on a warm engine.

Anyone want to trade an old Volvo for an '87 300sdl?

There are specifications hot and cold for the 617. My car has a sticker under the hood specifying x clearance at y temp. IIRC, exhaust is 0.3mm hot, 0.35mm cold. intake 0.1mm hot, 0.15mm cold. Check yours!

listen, look, .........and duck.

Fortyish should be perfect if you've let it sit overnight. Good luck keeping your fingers from freezing. I don't think that's cold enough to require a different setting. I think I remember reading that the gaps change when it gets considerably colder though.
