Squish area and distance

[DerSchwede]

Hi,

does anyone have the squish distance between the piston top and the head surface at TDC recorded for a standard euro M30?

In this particular case it's a 218 bhp 535i engine from a '85 535i.

Thanks
A

.889mm to 1mm

That would be best for most engines anything less would not be best... Quench as they call it.... .035 to .040 inches...
