Minimal Valve Clearances

[Mad Professor 7]

The good old joke book states the following.

 

Valve Clearances (Engine Cold)

Inlet: 0.15 - 0.25mm

Exhaust:: 0.35 - 0.45mm

 

I would like to know what is the minimal safe Valve Clearances you can use on the 205 8v engine.

 

At this point in time I am using.

Inlet: 0.15mm

Exhaust:: 0.30mm

 

I know there was a post quite some time about this, But I am unable to find it at this time.

 

Thanks For Your Time.

 

Best Regards.

Pumaracing says:

0.20-0.25mm on the inlets and 0.30-0.35mm on the exhausts btw. The Pug spec on the exhaust is unnecessarily large IMO and engines run quieter and smoother with my own settings.

Hope that helps.
