Engine Codes?

[16_Valve]

My Clio is a 1.4 (1390cc) 16v ... Log book says first use 22/10/2003 .. I've seen loads of engine codes on the forum i.e. F4R - F7P - 197 -172 - F7R - 182 - 255 etc. Haven't got a clue what they mean!? Does anyone know the correct code for my Clio? Thanks in advance, Steve

There's also suffix codes for the engines as well
