Valve adjustments
Checked my valves the other day, and I just want some advice on what to adjust them to. My car always sounds a bit 5 cylinder, so I was hoping to find some of them very tight.
I checked them hot, following the advice in this thread (1.6TD): http://www.brick-yard.co.uk/forum/th...opic33228.html I'm confused by the figures shown though in the book. Why are the figures WIDER for a hot engine? I thought the rule was that everything expands, so clearances get less on a hot engine? Cold Engine: Intake = 0.15-0.25mm Exhaust = 0.35-0.45mm Warm engine: Intake = 0.20-0.30mm Exhaust = 0.40-0.50mm These are my values at the moment. They all look to be at the low end, or just below spec, apart from 11&12, which are a bit tight. Is this enough to cause my engine to sound a bit 5 cylinder at idle when hot? 1 (ex) - 0.40 - 3.70 2 (in) - 0.22 - 3.90 3 (ex) - 0.41 - 3.85 4 (in) - 0.21 - 3.90 5 (ex) - 0.43 - 3.85 6 (in) - 0.25 - 3.85 7 (in) - 0.23 - (shim wouldn't come out) 8 (ex) - 0.43 - 3.80 9 (in) - 0.25 - (shim wouldn't come out) 10 (ex) - 0.41 - 3.85 11 (in) - 0.22 - 3.80 12 (ex) - 0.36 - 3.80
