Valve adjustments

[ian2000t]

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):

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
