Clio 172 head combustion chamber volume

hmh

Car  Renault Clio RS 172 ph1
Anyone has precise numbers of combustion chamber volume in the head of Clio 172 (F4R 732)? Or a reference to a good description how to measure it. My measurments give me numbers between 30 and 40cm3 :dapprove:
 
I used petrol for my previous measurments and it flew out of camera even before camera was filled completely. Today I tried regular sunflower oil and measured 43cm3 before it flew out. Anyone has other numbers?
 
are you using a flat piece of perspex with 2 holes drilled, and some grease on the head face to make a seal? brake cleaner or de-greaser is good to use.
 
you cant acurately ask this question as every head will be different! you can only give a rough idea of what they could be.

You can get specific measuring fluid, its called GUNK, works a treat! as danny said, bit of grease round a perspex ring, with a hole in it, doesnt need to have two holes if you have the head on a slight angle, the air will buble out ok. dont use too much grease either,

we account for grease by subracting 0.2cc from the measure, but if your frugal you shouldnt need to subract anything :) thats just for the burger fingers amongst us!

petrol isnt the best idea!
 
Got head back from polishing (or right term would be grinding?), measured using kerosene and CD-shaped piece of plexiglas
My number is 46.4.
