technician reckoned it was LCF000190 but I think that's a part number.
OK, I have managed to locate and read the engine number - removed rear shelf panel and went in from above rather than below.
According to the V5 the car should have 18K4KP25590284 fitted to this April 2003 car whereas what is fitted (and it's not easy to read is it?) is 18K4KN36423310. Now I think I have an MGF Trophy 160 engine rather than a MGTF engine, being 2nd hand it has "Trophy 2" hand written on the cam cover presumably for the dismantler to identify.
So, as far as I see I have an older engine in what I thought was a 39K car. Minded to see about handing it back. Shame really as it looks good in red and seems to go well.
